Description

Packaging for dental implants {package for dental implant}

The present invention relates to a packaging container for a dental implant, and more particularly, to a packaging container for a dental implant, in which a surface of a fixture is modified to be hydrophilic in order to accelerate initial bone formation and shorten the period of osseointegration during placement of the fixture, To a packaging container for a dental implant.

Generally, implants are replacements for restoring human tissues when they are lost. In dentistry, fixtures (artificial teeth), such as titanium, which have less rejection to the human body to replace the teeth of lost teeth, A crown which is joined to an artificial root placed on an alveolar bone to form a chewing surface, and the like, and the original function of the tooth can be restored by using the implant.

Here, the implant such as the fixture is antibacterial-treated, sealed, and stored in order to prevent infection of oral tissues such as the alveolar bone, etc. due to contamination by foreign substances or bacteria at the time of implantation.

In addition, most fixtures are processed to have a hydrophilic surface through processes such as RBM and SLA. At this time, when the surface of the fixture is exposed to the air after the process, the oxide layer increases with time, and the surface energy is stabilized by the contaminant source such as hydrocarbon compound and becomes hydrophobic.

As a result, the wettability to the body fluids and the blood is decreased, and the period of osseous fusion is increased, and the recovery period until the implant is stabilized is increased.

Conventionally, there has been devised a technique of packing a sterilized fixture into a container, irradiating ultraviolet rays to the outside of the container, and increasing the surface energy of the fixture packed in the container to secure hydrophilicity.

However, in the conventional ultraviolet processing apparatus, ultraviolet rays having low transparency are irradiated from the outside of the container into the inside of the container, so that a container made of a special material capable of transmitting ultraviolet rays is required.

Moreover, the intensity of ultraviolet rays emitted from the light emitting device not only decreases in intensity according to the transmittance of the container but also decreases sharply as the distance from the light emitting device increases.

Accordingly, since a light emitting device that emits ultraviolet rays of high intensity is required in order to irradiate the fixture with ultraviolet rays having sufficient intensity for surface treatment and sterilization, there is a problem that the configuration of the apparatus is complicated and the power consumption is increased, There is a risk of causing fatal damage to the human body.

1 to 5, a packaging container for a dental implant according to an embodiment of the present invention includes a base body 330, a bushing 360, and a light emitting unit 50.

Here, the base body 330 may have various shapes such as a cylinder, a polygonal column, and the like. In addition, it may be provided so as to have a water droplet-shaped cross section protruding radially outward from one side of the circumference from a circular cross-section so as to prevent loss, fall, and the like caused by cloud or the like when collapsed.

Meanwhile, it is preferable that a receiving hole 331 is formed in the base body 330 to accommodate the first surface modification and sterilization-processed fixture f for a tooth implant.

At this time, the receiving hole 331 is formed so as to pass through the base body 330 in the up and down direction, and to allow the fixture f to be smoothly stored and taken out, And has an inner diameter, and is formed to have a length of the fixture (f).

In detail, the fixture (f) is provided with a thread (s) to be placed on the alveolar bone of the subject and has a fastening hole formed on the upper surface thereof, such as an abutment for dental implant and a crown.

At this time, the fixture (f) may be formed of a metallic material such as titanium which is high in strength and excellent in corrosion resistance and bio-evolutionary. The fixture (f) is subjected to a first surface modification process so that the outer surface and the screw portion (s) have wettability with body fluids and blood. The fixture (f) Lt; / RTI >

For example, the fixture (f) may be surface-treated with resorbable blasting media (RBM) in which a biocompatible medium such as aluminum oxide, titanium oxide, or calcium phosphate is sprayed to form roughness on the surface. Also, after the RBM surface treatment, the first surface modification treatment can be performed through SLB (sandblasted, large-grit, acid-etched) surface treatment which performs chemical etching using an acid solution or the like. The fixture (f) may be subjected to a primary sterilization process by exposing it to a cleaning liquid, ultraviolet rays, plasma, ozone, or the like.

Accordingly, side effects such as infection and inflammation during placement of the fixture (f) can be minimized, and stable fixation of the fixture (f) can be achieved.

The base body 330 may be made of polytetrafluoroethylene (PTFE) having a reflectance of 90% or more with respect to ultraviolet rays. Accordingly, ultraviolet rays emitted from the light emitting unit 50, which will be described later, can be reflected through the inner periphery of the receiving hole 331 and irradiated onto the surface of the fixture f.

A support step 333 is formed at an upper edge of the accommodating hole 331 so as to be extended and extended radially outwardly at an upper end portion of the inner circumference of the accommodating hole 331.

At this time, the bushing 360 can be inserted into the support step 333, and the bushing 360 fixes the received fixture f so as to be spaced from the inner circumference of the receiving hole 331. That is, the fixture f may be fixed to the inner surface of the receiving hole 331 to prevent contact or friction when the bushing 360 is inserted into the support step 333 and fixed.

The bushing 360 may be divided into a plurality of arc-shaped divided body portions 360a and 360b. That is, the plurality of divided body portions 360a and 360b may be inserted into the receiving hole 331 so as to cover the outer circumference of the fixture f along the support step 333.

The split bodies 360a and 360b may be divided into a predetermined range along the circumferential direction to cover the outer periphery of the fixture f and the support holes 331, And the fixture f may be fixed. When the divided body portions 360a and 360b are separated from the receiving hole 331 and the support step 333, the divided body portions 360a and 360b are easily separated from the fixture f .

More preferably, each of the divided body portions 360a and 360b is formed so that an outer peripheral portion thereof is formed in the inner periphery of the base body portion 330 and an inner peripheral portion thereof is formed to correspond to the outer periphery of the fixture f.

At this time, the upper portion of the outer peripheral portion of each of the divided body portions 360a and 360b may be formed to correspond to the inner space of the support step 333, and the lower portion may be formed to correspond to the inner diameter of the receiving hole 331. Of course, the outer peripheral portion of each of the divided body portions 360a and 360b may be formed to correspond to the inner space of the support step 333 extending from the inner diameter of the receiving hole 331, as the case may be.

In this embodiment, the upper part of the outer peripheral part of each of the divided body parts 360a and 360b corresponds to the inner space of the support step 333, and the lower part corresponds to the inner diameter of the receiving hole 331 As shown in Fig.

That is, the upper end of the outer circumferential portion of each of the divided body portions 360a and 360b is provided with an engagement wing portion 361 protruding radially outwardly to be engaged with the support step 333, and each of the divided body portions 360a and 360b Is provided to have an outer diameter corresponding to the inner diameter of the receiving hole 331.

A recessed portion 363 may be formed in the inner peripheral portion of each of the divided body portions 360a and 360b so that the upper end of the fixture f may be inserted into the split body portions 360a and 360b, Shaped cross-section may be provided as a circular arc-shaped member having a 'C' shape.

Accordingly, the divided body portions 360a and 360b cover the fixture f with the depression 363 facing the screw portion s, so that the outer peripheral portion covers the fixture f, And the inner circumference of the accommodating hole 331.

On the other hand, the fixture f is inserted into or drawn out from the accommodating hole 331 using a surgical tool such as a tweezers or a drill. The fixture f is inserted or drawn into the depression 363 while the divided body portions 360a and 360b are inserted into the support step 333 and the accommodation hole 331. [

Then, the practitioner mounts the surgical tool on the fastener of the fixture (f) to insert or withdraw the fixture (f) into the depression (363). At this time, the fastening portion of the treatment tool can be fastened to the fastening hole of the fixture (f) by interference fit. In the fitting process, the practitioner presses the fixture (f) during the force fitting process to fasten the fastening portion of the surgical tool to the insertion hole of the fixture (f).

In this case, fine voids are formed between the divided body portions 360a and 360b according to the pressing force applied to the fixture f to reduce the adhesion to the fixture f, There is a problem that it is released into the accommodating hole 331.

At this time, when the fixture (f) is released into the receiving hole (331), the surface of the fixture (f) may be contaminated with bacteria or foreign matter. Here, the practitioner has to repeatedly perform the primary surface modification treatment and the primary sterilization treatment of the fixture (f) to prevent infection of the patient to which the fixture (f) is to be placed.

Further, when the fixture (f) is released into the accommodating hole (331) during the drawing process after the secondary surface modification, the first surface modification process, the first sterilization process, and the second surface modification process, The operator is required to proceed again and again, resulting in a time-consuming operation, resulting in a reduction in the working efficiency.

Accordingly, the present invention provides a structure for solving the above problems.

In detail, the inner peripheral portion of each of the divided body portions 360a and 360b is preferably formed with a slanting inclined surface portion 362 so that the diameter becomes narrower toward the lower side. The inclined slanting surface portion 362 is formed by tapering or the like It can be formed obliquely.

At this time, the engagement slope portion 362 may be formed along the inner periphery of the divided body portions 360a and 360b. That is, when the divided body portions 360a and 360b are engaged, the bushing portion 360 may be formed such that the inner portion thereof passes through the bushing portion 360 and is inclined downwardly inwardly in the radial direction. Since the fixture f has a larger upper end outer diameter than the lower end outer diameter, the upper end of the fixture f is in contact with one side of the engaging slope part 362 in a state where the divided body parts 360a and 360b are engaged And can be supported in the radially inward state.

At this time, the engaging slope portion 362 extends downward from one side of the upper edge of the depression 363 so as to be inclined downwardly inward in the radial direction, and is formed along the rim of the depression 363, It is preferable that the diameter is smaller than the rim diameter.

The engaging slope portion 362 may be formed to the other side of the bottom edge of the depression 363 so that the upper end of the fixture f is hooked and the lower end thereof is inserted into the accommodating hole 331. That is, the outer surface of the locking slope surface portion 362 may be formed as a substantially inverted conical profile.

The engaging slope portion 362 is formed in a part of the depression 363 from one side of the upper edge of the depression 363 to the other side of the lower edge of the depression 363 so that the area of contact with the fixture f Can be minimized. Therefore, the fixture (f) is fixed to the bushing (360), and the area irradiated with ultraviolet rays is increased, so that the efficiency of the secondary surface modification can be increased.

Of course, depending on the case, the latching slope portion 362 may extend downward from the upper rim of the inner peripheral portion of the divided body portions 360a and 360b to the lower rim.

At this time, the diameter of the lower end of the locking slope portion 362 is preferably smaller than the outer diameter of the upper end of the fixture f. In detail, the fixture f is inserted into the accommodating hole 331 through the inside of the engaging slope portion 362. [ The lower end of the fixture f may be inserted and the upper end of the fixture f may be engaged with the fixture f because the lower end of the fixture slope portion 362 is smaller than the outer diameter of the upper end of the fixture f.

Accordingly, even if minute voids are formed between the divided body portions 360a and 360b due to the pressing force generated in the insertion or withdrawal of the fixture f, the fixture (f) Since the upper end portion is caught and prevented from being separated by the receiving hole 331 and can be stably fixed, the stability of the apparatus can be further improved. In addition, since the fixture (f) is prevented from being separated from the fixture (f) during the mounting process of the fixture (f) and the surgical tool, the work process such as the surface modification and disinfection process is repeated, .

The engaging slope portion 362 may be inclined downwardly inward in the radial direction at a predetermined inclination angle?. At this time, the predetermined inclination angle? May be set to 3 to 5 degrees, and may be set differently depending on the type and shape of the fixture (f).

Here, each of the divided body portions 360a and 360b is formed such that the engagement slope portion 362 is inclined downward at the predetermined inclination angle?, So that one side of the inner periphery is in close contact with the outer periphery of the received fixture f . ≪ / RTI >

Therefore, the received fixture (f) can be prevented from being released into the accommodating hole (331) by external force such as vibration or impact, and can be fixed apart from the inner circumference of the accommodating hole (331). In addition, since the engaging slope portion 362 is formed at a gentle slope angle, interference during insertion of the fixture f can be minimized and wear or damage due to contact with the edge can be prevented.

The bushing unit 360 may be provided with various predetermined inclination angles θ so that the operator can adjust the bushing unit 360 according to the type or outer diameter of the fixture f for secondary surface modification. The present invention can be applied to the packaging container for dental implants.

The engagement thread 362a of the upper end of the received fixture f may be formed in the engagement slope 362. [ In detail, the engaging threads 362a may be formed in the circumferential direction corresponding to the pitch intervals and angles of the thread portions s along the engaging slopes 362.

The engaging groove 362b may be formed in the engaging slope 362 as the engaging thread 362a protrudes and the engaging groove 362b may be formed in the radial direction It can be recessed outward. That is, the threaded portion s can be screwed into the engagement groove portion 362b, and the engagement thread 362a can be interlocked with the threaded portion s. Therefore, the fixture (f) can be stably fixed to the bushing (360) and stably stored without flowing in the accommodating hole (331).

In addition, the engaging thread 362a protrudes from the engaging slope portion 362, and the end portion may extend radially inward as it goes downward. The engaging thread 362a may be formed so that the inner circumferential surface of the engaging thread 362a is inclined downward inward in the radial direction, corresponding to the predetermined inclination angle?.

That is, the inner circumferential surface of the engaging thread 362a may be formed such that the profile of the cross-sectional profile has a continuous straight inclined surface corresponding to the inclination angle. At this time, when the fixture f is inserted into the depression 363, the lower end of the fixture f is inserted into the accommodating hole 331 without being caught by the engaging thread 362a And the upper end may be caught by the engagement thread 362a.

Accordingly, since the fixture f is prevented from being released into the receiving hole 331 during rotation for threading by the engaging thread 362a protruding from the lower end of the engaging slope portion 362, The workability can be improved.

At least one restraining protrusion 364 is formed on the bushing 360 in a radially outward direction. Specifically, the locking protrusion 364 may protrude radially outward from one side of the locking protrusion 361, and may be formed corresponding to the thickness of the locking protrusion 361.

It is preferable that a restricting groove portion 337 is formed on the rim of the support step 333 in a radially outward direction corresponding to the restricting projection 364. The locking groove 337 may be formed radially outward from the inner circumferential surface of the support step 333, which is opposed to the outer circumferential surface of the locking wing 361 when the bushing 360 is inserted.

When the bushing 360 is inserted into the support step 333 and the receiving hole 331, the restricting projection 364 is inserted into the restricting recessed portion 337, and the bushing 360 is rotated in one direction Can be restrained.

Here, it is preferable to understand that the bushing 360 is inserted into the support step 333 and the accommodating hole 331 to rotate in one direction from the clockwise direction to the counterclockwise direction.

Accordingly, the one-way rotation of each of the divided body portions 360a and 360b is restrained, so that the restricting protrusion 364 can be prevented from rotating even when the drill device is rotated in a state of being fastened to the fastener of the fixture f, And can be prevented from rotating. Further, it is possible to prevent the support step 333 and the accommodating hole 331 from being separated from each other by rotational driving of a drill or the like used when inserting or withdrawing the fixture f. The fixture (f) can be easily screwed to the engagement thread (362a) as the divided body portions (360a, 360b) are constrained in one-directional rotation, so that workability can be improved.

At this time, the restraining protrusion 364 may be formed to have a width smaller than the entire width of the engaging wing 361. Here, the overall width of the engagement wing 361 is preferably a length corresponding to a substantially outer diameter of the bushing 360 including the engagement wing 361.

 That is, the locking protrusion 364 can prevent the bushing 360 from interlocking with the fixture f, even if the drilling device is rotationally driven while being fastened to the fastener of the fixture f As shown in FIG.

Accordingly, the operator can stably insert the fixture (f) into the oral cavity of the patient after fastening the fixture (f) to the surgical tool. In manufacturing the bushing (360) So that material requirements can be minimized and the economical efficiency can be improved.

In addition, the end of the restricting projection 364 may extend in a direction perpendicular to the tangent of the outer periphery of the engagement wing portion 361. At this time, the restraining protrusion 364 can prevent the bushing 360 from rotating in a stable manner in either the clockwise direction or the counterclockwise direction with respect to the one-directional rotation. Of course, the restraining protrusion 364 may extend in a direction having a predetermined angle from the tangent of the outer periphery of the engaging wing portion 361, as the case may be.

The end of the restraining protrusion 364 may have a rectangular shape corresponding to the thickness of the retaining protrusion 361. Of course, it may be provided in a polygonal shape of a pentagonal shape to a hexagonal shape, or may have an elliptical cross-sectional shape depending on the case. If the shape of the restricting projection 364 is not easily separated from the restricting groove portion 337 by a rotational force, . In addition, the restricting projection 364 may have a cross-sectional shape wider toward the radially outward side, and may have a trapezoidal cross-section as viewed in the up-down direction.

The bushing 360 is divided into the divided body portions 360a and 360b so that the restricting protrusions 364 may protrude from one of the divided body portions 360a and 360b. At this time, the plurality of restraining protrusions 364 may be provided, or a plurality of the restraining protrusions 364 may be provided on one of the divided body portions 360a and 360b.
