Description

  The present invention prevents impurities from adhering to the surface of a stored dental implant fixture, particularly the surface of a bone-implanted portion of the fixture, and easily maintains the sanitary condition of the fixture surface until immediately before use. The present invention relates to a fixture storage container.

  Since the fixture of a dental implant is embedded in the jawbone, it is strongly required that the surface of the bone-implanted portion of the fixture is particularly hygienic. This is because when the fixture is embedded in the jawbone, the generation of bone on the surface of the bone embedded part is not only the surface shape of the bone embedded part of the fixture, but also the surface of the bone embedded part of the fixture. Because it depends greatly on the degree, it is very important to prevent a lot of impurities from adhering to the surface of the fixture, especially the surface of the bone embedded part of the fixture when performing dental implant treatment. .

  As an implant system devised to maintain the sanitary condition of the surface of such a fixture, it is composed of a dental implant (fixture) and a holding member, a clamp member or the like attached to the oral cavity of the dental implant. (For example, refer to Patent Document 1). However, this implant system is simply provided with a holding member or the like so that the fixture is not directly touched by hands, and prevents impurities and the like from adhering to the surface of the fixture from the surrounding environment. No such ingenuity has been made.

In order to prevent impurities and the like from adhering to the surface of the fixture from such an environment, the fixture storage container is often sealed in a substantially vacuum state.
However, even if the amount of impurities is reduced by making the inside of the fixture storage container into a substantially vacuum state, the impurities that have already adhered to the fixture storage container are peeled off during transportation, etc. The impurities remaining in the fixture storage container gradually adhere to the fixture over time. Therefore, if the fixture is stored in the fixture storage container for a long period of time, impurities will inevitably adhere to the surface of the fixture. It is necessary to take measures to prevent impurities from adhering to the surface of the fixture in the char storage container.

JP 2006-43453 A

  In view of the above-mentioned problems, the present invention maintains the sanitary condition of the fixture surface until immediately before use because impurities are unlikely to adhere to the surface of the stored dental implant fixture, particularly the surface of the bone embedded portion of the fixture. It is an object to provide an easy-to-use fixture storage container.

As a result of intensive studies to solve the above problems, the present inventors have found that the internal gas that can contact the surface of the bone embedding portion of the fixture in the storage body main body in which the fixture is stored can flow. If the inner area of the container body is made larger than the surface area of the bone-embedded part of the fixture while the volume of the space is reduced to reduce the total amount of impurities in the space inside the container body, the impurities are dispersed. Because it adheres, the impurities attached to the surface of the bone embedding part of the fixture with a small surface area compared to the inner area of the container body are relatively reduced,
The fixture storage container is moved from the fixture insertion port side, which is closed at one end and provided at the other end, to the storage unit main body in which the fixture for dental implants is stored, and to the fixture insertion port side of the storage unit main body. The volume of the space inside the housing body in which the internal gas that can be brought into contact with the surface of the bone embedding portion of the fixture can flow is 1 of the volume of the bone embedding portion of the fixture to be accommodated. .3 to 4 times, and the area of the inner surface of the container body that can be contacted by the internal gas is not less than five times the surface area of the bone embedding part of the stored fixture, or
The fixture storage container is used for a dental implant from a fixture insertion port side provided with an inner body with a thin wall and a substantially arc-shaped or substantially circular cross-section, with one end closed and the other end closed. Consists of a storage body that is stored in a state where the fixture is not in contact with the interior body, and a lid that is mounted on the fixture insertion port side of the storage body, allowing contact with the surface of the bone-implanted portion of the fixture The volume of the space inside the storage body through which the internal gas can flow is 1.3 to 4 times the volume of the bone embedding part of the stored fixture, and the internal gas of the storage body and the interior body can contact each other. If the area of the correct part is more than 5 times the surface area of the bone embedded part of the fixture to be stored,
Compared to the surface area of the bone-embedded portion of the fixture, the area of the inner surface of the container body that can be contacted by the internal gas or the area of the part that can be contacted by the internal gas of the container body and the interior body is five times or more. Most of the impurities adhere to the inner surface of the container body and the interior body, so that the surface area of the bone-embedded part of the fixture can be kept hygienic, and the fixture is stored when the fixture is taken out or transported. The surface of the bone-implanted portion of the fixture and the main body of the storage body so that impurities do not adhere to the surface of the bone-embedded portion of the fixture due to contact with the inner surface of the body main body or the inner surface of the interior body, and the fixture is not damaged. Since there is a sufficient gap between the inner surface of the housing and the inner surface of the interior body, at least the volume of the space in the housing body where the internal gas that can contact the surface of the bone-buried portion of the fixture can flow is fixed. The volume of char must be 1.3 times or more of the bone embedding part, but if the volume of the space inside the container body through which the internal gas can flow is too large, the amount of impurities in the container body Therefore, the present invention has been completed by investigating that the volume of the space inside the housing body through which the internal gas can flow must be suppressed to four times or less the volume of the bone-buried portion of the fixture. .

That is, the present invention has a storage body main body in which one end is closed and a fixture for a dental implant is stored from a fixture insertion port side provided at the other end, and is mounted on the fixture insertion port side of the storage body main body. The volume of the space inside the housing body in which the internal gas that can contact the surface of the bone embedding portion of the fixture can flow is 1.3 to 3 of the volume of the bone embedding portion of the fixture to be housed. A fixture storage container characterized in that the area of the inner surface of the storage body main body, which is four times larger and the inner gas can contact, is at least five times the surface area of the bone-embedded portion of the stored fixture; ,
A thin-walled interior body having a substantially arc shape or a substantially circular cross section is mounted inside, one end is closed, and the fixture for a dental implant is the interior body from the fixture insertion side provided at the other end. A storage body that includes a storage body that is stored in a non-contact state and a lid that is mounted on the fixture insertion port side of the storage body, and that can flow an internal gas that can come into contact with the surface of the bone embedding portion of the fixture. The volume of the space inside the main body is 1.3 to 4 times the volume of the bone embedded portion of the fixture to be stored, and the area of the portion where the internal gas of the storage body and the interior body can contact is stored. The fixture storage container is characterized in that it has a surface area of 5 times or more of the bone embedded portion of the fixture.

Moreover, in the aspect which does not have an interior body, it is the inner surface of the storage body main body which can contact internal gas, and in the aspect which has an interior body, the inner surface of the storage body main body which can contact internal gas, and an interior body If an unevenness with a height difference of 0.1 to 1.5 mm is provided on at least one of the inner surface of the interior and the outer surface of the interior body in order to increase the area of the portion that can be contacted by the internal gas, the height difference is 1 Since it is a small unevenness of less than 5 mm, the unevenness can be easily provided without making the inner diameter of the storage body or interior body too large, so the volume of the space inside the storage body where the internal gas can flow is determined by the bones of the fixture It is easy to suppress the volume of the embedded portion to 4 times or less, and processing is difficult if the height difference is too small. However, since the height difference is 0.1 mm or more, processing is relatively easy and preferable.
Furthermore, in the aspect not having the interior body, the ten-point average roughness of the inner surface of the storage body main body that can be contacted by the internal gas, and in the aspect having the interior body, the internal body can be contacted by the internal gas. If the 10-point average roughness of at least any one of the inner surface, the inner surface of the interior body, and the outer surface of the interior body is 3 to 8 μm, the inner body can be contacted with the internal gas only by performing a simple surface treatment. It is preferable because the area of the inner surface and the area of the portion where the internal gas of the housing body and the interior body can come into contact can be easily increased.

Further, when the storage body main body is formed of any one of titanium, titanium alloy or glass in both aspects, or when the interior body is formed of titanium or titanium alloy in the aspect having the internal body, And the interior body is made of the same titanium or titanium alloy as the fixture, so that the adhesion of impurities is almost the same in the housing body and interior body and the bone embedded part of the fixture, and the surface area is relatively small. Impurities adhering to the fixture can be reliably reduced, and if the container body is made of glass, it is preferable because it can be manufactured inexpensively and easily.
And in both aspects, when it has further the sealing packing with which it mounts between a storage body main body and a cover body, it is easy to maintain the state also at the time of decompression sealing, and storage for fixtures It is preferable that impurities do not enter the container from the outside.

The fixture storage container according to the present invention includes a storage body body in which one end is closed and a fixture for a dental implant is stored from the fixture insertion port side provided at the other end, and the fixture of the storage body body The volume of the space inside the housing body where the internal gas that can contact the surface of the bone embedding portion of the fixture can flow is determined by the volume of the bone embedding portion of the fixture to be housed. The area of the inner surface of the container body that is 1.3 to 4 times the volume and that can be contacted by the internal gas is 5 times or more the surface area of the bone-embedded portion of the fixture to be stored,
Alternatively, the fixture storage container is used for a dental implant from the side of the fixture insertion port provided at the other end with a thin-walled inner body having a substantially arc-shaped or substantially circular cross-section and closed at one end. The fixture body consists of a storage body that is stored in a state where it does not contact the interior body, and a lid that is attached to the fixture insertion port side of the storage body, allowing contact with the surface of the bone-implanted portion of the fixture The volume of the space inside the storage body through which the internal gas can flow is 1.3 to 4 times the volume of the bone embedding part of the stored fixture, and the internal gas of the storage body and the interior body can contact each other. Because the area of the site is more than 5 times the surface area of the bone embedded part of the fixture to be stored,
Compared to the surface area of the bone-embedded part of the fixture, the area of the inner surface of the container body that can be contacted by the internal gas or the area of the part that can be contacted by the internal gas of the container body and the interior body is 5 times or more, Since most of the impurities adhere to the inner surface of the container body and the interior body, the surface area of the bone embedded portion of the fixture can be kept hygienic, and the area of the inner surface of the container body that can be contacted by the internal gas or The volume of the space inside the container body where the internal gas that can be contacted can flow is 4 of the volume of the bone burying portion of the fixture, even though the area of the part that can contact the internal gas of the container body and the interior body is large. Since there is less unnecessary space in the container body and the total amount of impurities in the container body can be reduced, the amount of impurities attached to the surface of the bone-implanted portion of the fixture can be reduced. Char Since the volume of the space inside the container body where the internal gas that can be contacted can flow easily can be maintained, and the volume of the bone embedded part of the fixture is 1.3 times or more, A sufficient gap is created between the surface of the bone embedding part of the fixture and the inner surface of the housing body or the inner surface of the interior body, so that the fixture can be attached to the inner surface of the housing body when removing the fixture or during transportation. There is no contact with the inner surface of the interior body so that impurities do not adhere to the surface of the bone-buried portion of the fixture or the fixture is not damaged.

Moreover, in the aspect which does not have an interior body, it is the inner surface of the storage body main body which can contact internal gas, and in the aspect which has an interior body, the inner surface of the storage body main body which can contact internal gas, and an interior body When at least one of the inner surface and the outer surface of the interior body is provided with irregularities having a height difference of 0.1 to 1.5 mm in order to increase the area of the portion that can be contacted by the internal gas, Since the height difference is a small unevenness of 1.5 mm or less, the unevenness can be easily provided without enlarging the inner diameter of the storage body main body or the interior body, so the volume of the space in the storage body main body through which the internal gas can flow is reduced. It is easy to suppress the volume of the bone embedded part of the fixture to 4 times or less, and if the height difference is too small, it is difficult to process, and in addition, it is necessary to provide a large number of irregularities to secure a sufficient area. Difficult, but height difference is 0.1m m or more, it can be processed relatively easily,
Furthermore, in the aspect not having the interior body, the ten-point average roughness of the inner surface of the storage body main body that can be contacted by the internal gas, and in the aspect having the interior body, the internal body can be contacted by the internal gas. When the 10-point average roughness of at least any one of the inner surface, the inner surface of the interior body, and the outer surface of the interior body is 3 to 8 μm, the housing body can be contacted with the internal gas only by performing a simple surface treatment. It is possible to easily increase the area of the inner surface of the main body and the area of the portion where the internal gas of the housing body and the interior body can contact.

  Further, when the storage body main body is formed of any one of titanium, titanium alloy or glass in both aspects, or when the interior body is formed of titanium or titanium alloy in the aspect having the internal body, And the interior body is made of the same titanium or titanium alloy as the fixture, so that the adhesion of impurities is almost the same in the housing body and interior body and the bone embedded part of the fixture, and the surface area is relatively small. Impurities adhering to the fixture can be surely reduced, and if the container body is made of glass, it can be manufactured inexpensively and easily, and in both aspects, for sealing that is mounted between the container body and the lid In the case of further having the packing, it is easy to maintain the state even when sealed under reduced pressure, and impurities may not flow into the fixture storage container from the outside. Than is.

Hereinafter, the storage container for a fixture according to the present invention will be described in detail with reference to the drawings.

FIG. 4 is an enlarged plan view, FIG. 4 is a cross-sectional explanatory view showing a main part of the fixture storage container according to the present invention shown in FIG. 1, and FIG. FIG. 6 is a cross-sectional explanatory view of a main part of another embodiment of the fixture storage container according to the present invention showing a state where the fixture is fixed by a pressing bar attached to the lid, and FIG. 6 is a plan view of the fixture storage container of FIG. FIG. 7 is a perspective view showing still another embodiment of the fixture storage container according to the present invention, showing a state in which the interior body is removed from the inside of the storage body. FIG.

  In the drawings, X is a fixture for a dental implant. In the fixture storage container according to the present invention, the fixture X to be stored is not particularly limited. For example, as shown in FIG. 4 and FIG. A screw-type dental implant fixture that has a male thread and a self-tapping cutting edge groove in the male thread can be stored. Is preferably made of titanium or a titanium alloy that has biocompatibility and strength and is well bonded to bone. Note that the bone embedded portion Xa of the fixture X is a portion that is embedded in the jaw bone of the fixture X, and corresponds to a portion where a substantially male screw of the fixture X is formed.

  Reference numeral 1 denotes a storage body body in which one end is closed and a fixture X for dental implants is stored from a fixture insertion port side provided at the other end. The storage body body 1 includes an interior body 3 to be described later. In the aspect which does not have, it is 1 of the volume of the bone embedding part Xa of the fixture X in which the volume of the space in the container main body which can flow the internal gas which can contact the surface of the bone embedding part Xa of the fixture X is stored. It is formed so as to have an inner area that is three to four times as large as the surface area of the bone-embedded portion Xa of the fixture X to be accommodated. Reference numeral 2 denotes a lid attached to the fixture insertion port side of the housing body 1.

3 is a thin-walled interior body having a substantially arc shape or a substantially circular cross section, and in a mode in which this interior body 3 is mounted inside the housing body 1, the dental implant fixture X is an interior body. 3 is stored in the storage body main body 1 in a state where it does not contact 3.
In the embodiment having the interior body 3, the interior body 3 that can be contacted with the surface of the bone-embedded portion Xa of the fixture X only by housing the interior body 3 that has been subjected to unevenness or roughening treatment in advance in the housing body 1. The area of the portion that can be contacted with gas can be easily increased, and the housing body 1 can be manufactured more easily than the unevenness or the roughening treatment.

When the fixture X is taken out or transported, the fixture X comes into contact with the inner surface of the housing body 1 or the inner surface of the interior body 3, and impurities adhere to the surface of the bone embedded portion Xa of the fixture X. In order to prevent the fixture from being damaged, a gap is required between the surface of the bone embedding portion Xa of the fixture X and the inner surface of the housing body 1 or the inner surface of the interior body 3. The volume of the space inside the container body 1 in which the internal gas that can come into contact with the surface of the bone embedded portion Xa of the fixture X can flow is somewhat larger than the volume of the bone embedded portion Xa of the fixture X. Don't be.
Therefore, if a sufficient clearance is provided between the surface of the bone-embedded portion Xa of the fixture X and the inner surface of the storage body main body 1 or the inner surface of the interior body 3, it becomes easy to handle, and therefore the inside of the storage body main body 1 through which internal gas can flow. The volume of the space needs to be at least 1.3 times the volume of the bone-embedded portion Xa of the fixture X, but if it is too large, the total amount of impurities in the container body 1 increases, and the fixture X The surface of the bone embedded part Xa cannot be maintained hygienically. Accordingly, it is preferable that the volume of the space in the container body 1 through which the internal gas can flow is as small as possible, and therefore it is necessary to make it not more than four times the volume of the bone embedding portion Xa of the fixture X.

Conventionally, in order to reduce impurities adhering to the surface of the bone-embedded portion Xa of the fixture X, it has been considered only to reduce the pressure mainly, and the fixture X in the storage body 1 in which the fixture X is stored. The storage body main body 1 in a state where the volume of the space in the storage body main body 1 in which the internal gas that can contact the surface of the bone embedding portion Xa can flow is reduced to reduce the total amount of impurities in the space in the storage body main body 1. There was no idea to relatively reduce the amount of impurities adhering to the surface of the bone embedded part Xa of the fixture X by making the inner surface area larger than the surface area of the bone embedded part Xa of the fixture X.
For this reason, many of the conventional storage body main bodies 1 have a smooth inner surface, and there was no significant difference between the inner area of the storage body main body 1 and the surface area of the bone-embedded portion Xa of the fixture X. On the other hand, in the fixture storage container according to the present invention, the volume of the space inside the storage body main body 1 through which the internal gas can flow is at least 1.3 times or more than 4 times the volume of the bone embedded portion Xa of the fixture X. The interior area of the storage body 1 is set to be 5 times or more of the surface area of the bone-embedded portion Xa of the fixture X, or a separate interior body 3 is provided to provide 5 times or more of the surface area of the bone-embedded portion Xa of the fixture X. This is a very special fixture storage container that can relatively reduce impurities adhering to the surface of the bone-embedded portion Xa of the fixture X. The reason why the surface area of the bone-embedded portion Xa of the fixture X is 5 times or more is that when it is less than 5 times, impurities cannot be sufficiently adhered to the inner surface of the housing body 1.

  In addition, although the amount of impurities adhering to the surface of the bone embedded portion Xa of the fixture X may be affected by the volume and inner area of the space in which the internal gas of the lid 2 attached to the storage body 1 can flow, In many cases, the storage body 1 and the lid 2 are blocked by a mount or the like attached to the stored fixture X to form independent internal spaces in the fixture storage container. 2 does not adhere to the surface of the bone-embedded portion Xa of the fixture X stored in the storage body main body 1, and the internal space between the storage body main body 1 and the lid body 2 is in communication. Even in such a case, since the inner space of the lid body 2 is generally smaller than the inner space of the housing body 1, there is little influence of impurities in the inner space of the lid body 2, and the inner area of the lid body 2 is further reduced. The size of the bone X of the fixture X is Xa Although it is thought that it contributes to reducing the amount of impurities adhering to the site located on the outer lid 2 side, the impurities adhering to the bone embedded part Xa of the fixture X located on the opposite side of the lid 2 Since it is considered that the amount does not have a great influence, in the present invention, the storage body main body 1 or the inside of the storage body main body 1 having a large influence on the amount of impurities adhering to the bone embedding portion Xa of the fixture X is mounted. The relationship with the interior body 3 was defined.

Further, the present invention is intended to increase the area of the housing body 1 and the interior body 3 to relatively reduce impurities adhering to the surface of the bone-embedded portion Xa of the fixture X. It is important that the bone embedded portion Xa of the fixture X is stored in a firmly fixed state so that the surface of the bone embedded portion Xa of the fixture X does not come into contact with the inner surface of the storage body main body 1 and the inner surface of the interior body 3. Become.
Therefore, for example, as shown in FIG. 4, the mount 5 is attached in advance to the fixture X so that the fixture 5 is suspended in the storage body 1 and securely fixed and stored, or the fixture X is mounted as shown in FIG. 5. When inserted, only the tip thereof is brought into contact with the inside of the housing body 1, and the presser bar 6 fitted to the lid portion 2 is inserted into the hole formed on the upper side of the fixture X to fix the fixture. It is only necessary to support X and fix fixture X firmly.

Moreover, in the aspect which does not have the interior body 3, it is the inner surface of the storage body main body 1 in which internal gas can contact, and in the aspect which has the interior body 3, the inner surface of the storage body main body 1 in which internal gas can contact. Further, at least one of the inner surface of the interior body 3 and the outer surface of the interior body 3 is provided with unevenness with a height difference of 0.1 to 1.5 mm in order to increase the area of the portion that can be contacted by the internal gas. In this case, since the height difference is a small unevenness of 1.5 mm or less, the unevenness can be easily provided without enlarging the inner diameter of the storage body main body 1 or the interior body 3, so that the internal gas can flow. The volume of the space inside the storage body 1 can be easily suppressed to 4 times or less the volume of the bone-embedded portion Xa of the fixture X, and if the height difference is too small, processing is difficult, but the height difference is 0.1 mm or more. It can be processed relatively easily.
Further, in the embodiment not having the interior body 3, the ten-point average roughness of the inner surface of the housing body 1 that can be contacted by the internal gas, and in the embodiment having the interior body 3, the housing can be contacted by the internal gas. When the 10-point average roughness of at least any one of the inner surface of the body body 1, the inner surface of the interior body 3, and the outer surface of the interior body 3 is 3 to 8 μm, the internal gas can be obtained simply by applying a simple surface treatment. It is possible to easily increase the area of the inner surface of the storage body main body 1 that can be contacted and the area of the portion of the storage body main body 1 that can contact the internal gas of the interior body 3.

Moreover, when the storage body main body 1 is formed from either titanium, a titanium alloy or glass in both aspects, or when the interior body 3 is formed from titanium or a titanium alloy in the aspect having the interior body 3, Since the housing body 1 and the interior body 3 are made of the same titanium or titanium alloy as the fixture X, the ease of adhesion of impurities is reduced between the housing body 1 and the interior body 3 and the bone embedded portion Xa of the fixture X. Impurities adhering to the fixture X having a relatively small surface area can be surely reduced, and if the container body 1 is made of glass, it can be manufactured inexpensively and easily.
And in both aspects, when it has further the sealing packing 4 with which the storage body main body 1 and the cover body 2 are mounted | worn, it is easy to maintain the state, even when sealed under reduced pressure, Impurities do not enter the char storage container from the outside.

Next, the inner body 1 and the lid 2 are made of titanium, and the volume of the space in which the internal gas can flow is 420 mm ^3. The fixture storage container (Examples 1 and 2) according to the present invention in which the volume of the space is 432 mm ³ and the inner surface of the storage body 1 are not provided with irregularities, and the inner surface is not roughened. Using the fixture storage container (Comparative Examples 1 and 2) in which the volume of the space through which the internal gas can flow is 420 mm ³ , the fixture X (surface area of the bone embedding portion Xa: about 300 mm ²⁾ , An experiment was conducted to confirm how much impurities adhered to the surface of the bone-embedded part Xa having a volume of the bone-embedded part Xa of about 120 mm ³ ). Note that the interior body 3 is not attached to any fixture storage container.

In the storage body main body 1 of each comparative example (Comparative Examples 1 and 2), the area of the inner surface that can be contacted by the internal gas is about 310 mm ^2, which is substantially the same as the surface area (about 300 mm ² ) of the bone embedded portion Xa of the fixture X. Therefore, the requirement of the present invention that the surface area of the bone embedded portion Xa of the fixture X is 5 times or more is not satisfied.
By contrast, the housing main body 1 of each embodiment, in the area of the inner surface capable of contacting the internal gas of about 3210mm ² (Example 1) and about 4600Mm ² (Example 2), bone respective fixture X The surface area of the embedded portion Xa is about 10 times (Example 1) and about 15 times (Example 2), and satisfies the requirement of the present invention that the surface area of the bone embedded portion Xa of the fixture X is 5 times or more. ing.

The volume of bone implanting part Xa of the fixture X volume of container body 1 of the comparative examples (Comparative Examples 1 and 2) and each example (Examples 1 and 2) is housed in a 420 mm ³ and 432 mm ³ Is about 120 mm ³ , the volume of the space in which the internal gas can flow in the housing body 1 is 3.5 times and 3.6 times the volume of the bone-embedded portion Xa (120 mm ³ ) of the fixture X, respectively. Thus, the volume ratio of 1.3 to 4 times that is a requirement of the present invention is satisfied.

  As described above, in each of the comparative examples (Comparative Examples 1 and 2) and each of the Examples (Examples 1 and 2), the volume of the space in which the internal gas can flow in the housing body 1 is substantially the same. Using the storage body main body 1 in which the amount of impurities contained in the storage body main body 1 is substantially the same, the area of the inner surface that the internal gas of the storage body main body 1 can contact only in each of the examples (Examples 1 and 2). The experiment was conducted with a larger value.

  In this experiment, in order to measure the degree of adhesion of impurities, water was dropped on the surface of the bone embedded portion Xa of the fixture X taken out from each fixture storage container, and the wettability was examined. The wettability represents the wettability of the solid surface, and the index indicating the wettability is generally the contact angle between the solid surface and the liquid dropped on it (the angle between the solid surface and the end surface of the liquid). Used. Many impurities present in the atmosphere are hydrophobic, such as dust and human sebum, and when such impurities adhere to the solid surface, when the liquid is dropped, the liquid remains large in the shape of a hemisphere. Since it does not expand, the contact angle increases. On the other hand, when almost no impurities are attached to the solid surface, the solid surface is hydrophilic and has high wettability, and the liquid suspended on the solid surface spreads into a thin film and the contact angle becomes small.

(Experiment 1)
In Example 1, the inner surface of the container body 1 is provided with irregularities with a height difference of 0.6 mm on the inner surface, and the inner surface is further roughened with a ten-point average roughness of about 4.1 μm. The inner area of the fixture X was about 10 times as large as the surface area (about 300 mm ² ) of the bone-embedded portion Xa of the fixture X so as to be about 3200 mm ² .
Further, in this experiment, even if the fixture storage container has a small amount of impurities, the fixture storage container according to the present invention and the other fixture storage container have the bone embedded portion Xa of the fixture X stored therein. In order to show that there is a difference in the amount of impurities adhering to the surface, each fixture storage container (Example 1 and Comparative Example 1) was sealed at 0.1 kPa under reduced pressure, and then stored at room temperature for 30 days. did. After storage, the fixture X was taken out from each fixture storage container, and water was dropped on the surface of the bone embedding portion Xa to measure the contact angle.
The surface area of the bone embedded portion of fixture X and the inner area of each fixture storage container were measured with a gas adsorption surface area meter (specific surface area / pore distribution meter, manufactured by Shimadzu Corporation).

  The influence of impurities hardly appears on the surface of the bone-embedded portion Xa of the fixture X stored in the fixture storage container of Example 1, and the dripped water spreads thinly and exhibits high wettability, and the contact angle is Only 5 °. On the other hand, the dripped water did not spread greatly on the surface of the bone embedding portion Xa of the fixture X stored in the fixture storage container of Comparative Example 1, and the contact angle was 50 °. Comparing both, it can be seen that almost no impurities adhered to the surface of the bone-embedded portion Xa of the fixture X stored in the fixture storage container of Example 1.

(Experiment 2)
In addition, the surface of each fixture X is previously cleaned with Ar gas, and the fixture X is stored in the fixture storage container in a state where impurities are sufficiently removed from the surface of the fixture X. The storage container was filled with Ar gas and sealed without performing decompression or the like, and then stored at room temperature for 30 days. After storage, the fixture X was taken out from each fixture storage container, and water was dropped on the surface of the bone embedding portion Xa to measure the contact angle.

The container body 1 according to the second embodiment is provided with irregularities with a height difference of 1.3 mm on the inner surface thereof, and the inner surface is further roughened with a ten-point average roughness of about 6.5 μm. The inner area was about 15 times as large as the surface area (about 300 mm ² ) of the bone embedded portion Xa of the fixture X so that the area was about 4600 mm ² .
The surface area of the bone embedded portion of fixture X and the inner area of each fixture storage container were measured with a gas adsorption surface area meter (specific surface area / pore distribution meter, manufactured by Shimadzu Corporation).

In the fixture X stored in the fixture storage container of Comparative Example 2, water dripped on the surface of the bone embedding portion Xa did not spread greatly, and the contact angle was 53 °. The contact angle of Comparative Example 2 (53 °) was larger than the contact angle of Comparative Example 1 (50 °). The char X was washed with Ar gas, but it was thought that this was because the adhesion of impurities could not be sufficiently prevented because it was only filled with Ar gas.
Thus, although it is thought that there were slightly many impurities in Experiment 2, in Example 2, the area (4600 mm < ² >) of the inner surface of the container main body 1 is larger than the area (3200 mm < ² >) of the inner surface of the container main body 1 of Example 1. In the second embodiment, most of the slightly more impurities adhered to the inner surface of the housing body 1 of the second embodiment having a larger inner surface area, and as a result, are stored in the fixture storage container of the second embodiment. It is considered that almost no impurities adhered to the fixture X, and the contact angle of the stored fixture X was 3 °, which was smaller than Example 1 (5 °).

  As described above, the amount of impurities adhering to the surface of the bone embedded portion Xa of the stored fixture X is large only by the difference in the area of the inner surface of the storage body main body 1 in which the fixture X is stored from each experiment. It became clear that there was a difference.
