Description

Drill set for precisely guided dental implant surgery

The present invention relates to a drill set for implant surgery used for the precise treatment of dental implants, and to display the information on the length and diameter of the implant surgery drill constituting a suit in the shape and color on each drill The present invention relates to a drill set for implant surgery that forms a length and diameter information of a drill to be used in a surgical bushing assembly to prevent an error during surgery and to perform an accurate implant procedure.

In general dental implant surgery, tissue information is measured at the diagnosis stage, an implant procedure is planned from the measured information, and a surgical instrument is designated to proceed with the surgery. When multiple implant surgery is required, the patient's oral tissue for each implant position is needed. Measure the width and depth of each one.

The length and diameter of the implant, the angle of implantation, and the depth of implantation should be varied by implant according to information on the patient's oral tissue, for example, the thickness of the gingiva and alveolar bone, and the location of the nerve line. In addition to this, information on the exact length and diameter of the surgical instrument must be provided.

For this reason, conventional implant surgery, which requires the measurement of oral tissue in diagnosis, the establishment of a surgical plan based on it, and the measurement and correction in actual surgery, requires a very long operation time and high concentration, and thus must be treated accordingly. It is true that there is a lot of information to do.

In order to solve this problem, a precision guided implant surgery was devised so that the surgical plan established at the diagnosis stage can be realized in the oral cavity through a surgical guide fitting called a guide template.

1 is a view showing a guide template 10 for implant surgery developed and applied by the applicant. The description of the illustrated guide template 10 has been filed in Korean Patent Application No. 10-2016-0036619 (filed March 28, 2016).

The illustrated guide template 10 guides the advancing direction of the drilling drill and the depth of drilling of the buccal (B) and lingual (L) and occlusal (O) or gingiva (O) of the at least one tooth, and the drilling drill. Including the induction bushing 40 to limit the embedded portion 30. For reference, the applicant's guide template 10 includes a first thermoplastic sheet layer in which the support part 20 and the surgical part 30 are in close contact with the tooth side, and a second thermoplastic sheet bonded to the outside of the first thermoplastic sheet layer. It is characterized by consisting of two layers of layers.

Here, the support 20 refers to a part that plays a role of supporting and fixing the entire guide template 10 at a predetermined position in the oral cavity. Since the guide template 10 is made of a gingival model of which the tooth is lost and the first / second thermoplastic sheet that is tightly wrapped around the appropriate number of teeth, the support 20 has the same shape as the tooth or the gingiva. The shaped cavity is formed. Therefore, when the cavity is fitted to the teeth of the corresponding shape, the support 20 wraps the buccal side B and the lingual L and the occlusal side O, or the corresponding gingiva, of the tooth, thereby providing a guide template 10. ) Is fixed in the premises.

In addition, the surgical part 30 is a part in which an implant surgery is performed (a tooth missing part), and instead of a cavity for mounting the guide template 10, an induction bushing 40 for inducing the progress of the drilling drill is provided. Landfill is fixed, one guide bushing 40 is provided for each surgical site. That is, the inner diameter of each guide bushing 40 has a size corresponding to the outer diameter of the drill for drilling to be used for each surgical site to induce the drill to proceed in the correct direction. In addition, when the drill having a guide portion corresponding to the induction bushing 40 is used, the drill is limited to enter only a predetermined depth so that the drilling depth may be controlled without a separate scale measurement.

However, when drilling the alveolar bone to perform the implant, if the implant diameter of the implant is large, at least two stages should be first drilled using a small diameter drill first, and then a drill adapted to the final diameter should be used. For this purpose, a small diameter auxiliary bushing provided at one end or both ends of a bar-shaped auxiliary device is inserted into the induction bushing, and the other hand is drilled while holding the auxiliary device with one hand.

However, if you do not hold the auxiliary device by hand, the auxiliary bushing may rotate due to the rotation of the drill, and in order to prevent this, the drilling work is performed with only one hand. There is a hard side. Furthermore, there is a risk of accidentally injuring the patient's mouth when drilling, or additional personnel are required to hold the auxiliary bushing.

In addition, repeated use of the assistive device wears out the inner circumferential surface of the auxiliary bushing, resulting in a gap between the drill and the drill, which may result in inaccurate drilling.However, it is almost impossible to visually check the condition of the assistive device. Even if you need a separate gauge because it is inconvenient in many ways.

On the other hand, even in precision-guided surgery using guide templates, the selection and guidance of implant surgery, surgical instruments and implants is still performed in the same way as in conventional surgery. Numerical information about the diameter of the implant and the like was introduced.

The method of referring to printed output or computerized information on the monitor has the advantage of precision-guided surgery as it impedes the physician's concentration and causes surgical errors due to the inconvenience of having to alternate between the oral tissue and the output, which are the actual surgical targets. It was a factor that prevented it from performing properly. In addition, even if the surgical assistants guide the outputted surgical guidance information instead, it may not be mistransmitted during the information transmission, and there is a disadvantage in that additional manpower is required.

Korea Patent Registration No. 10-1039287 (July 2011) Korean Patent Registration No. 10-0993666 (announced 10 November 2010) Korea Patent Registration No. 10-1353335 (2014.01.17 notification) Korean Registered Patent No. 10-1344472 (announced Dec. 24, 2013)

Figure 2 is an exploded perspective view of the guided bushing assembly 100 included in the implant surgical drill set of the present invention, Figure 3 is an assembled perspective view of the guided bushing assembly 100, with reference to this in detail describing the present invention Shall be.

As shown in the figure, the induction bushing assembly 100 has two parts: an induction bushing 110 having a hollow cylindrical body 112 and an inner bushing 150 inserted into and coupled to the inner circumferential surface of the induction bushing 110. It consists of two parts.

First, the reason why the induction bushing assembly 100 is composed of two parts, the induction bushing 110 and the inner bushing 150, is divided into at least two steps when the diameter of the hole to be drilled during the implant surgery is large. This is because the perforation work should be performed to reduce the heat generation during the perforation of the alveolar bone and facilitate the perforation without difficulty.

That is, the inner diameter of the guide bushing 110 corresponds to the diameter of the hole to be finally made in the alveolar bone. When the inner diameter of the guide bushing 110 is larger than a predetermined level, the inner diameter of the guide bushing 110 is drilled at a time. If the patient's body and drill will be overwhelmed and the drilling work will be difficult. Therefore, it is preferable to proceed with the preliminary or primary drilling operation to a diameter smaller than the final diameter, for this purpose further comprises an inner bushing 150 having a small inner diameter that is detachably coupled to the induction bushing 110 will be.

When the induction bushing assembly 100 composed of two components, the induction bushing 110 and the inner bushing 150 is applied to the guide template described above, the inner bushing 150 is inserted into the induction bushing 110. After performing the first drilling, the inner bushing 150 is removed and the drilling work is completed by using a larger diameter drill.

Again, the configuration of the induction bushing assembly 100 of the present invention will be described in detail.

The induction bushing 110 is made into a shape cut off a portion of the cylindrical body 112 based on the hollow cylindrical body 112. Here, it is necessary to note that cutting a portion of the cylindrical body 112 does not intrude to the inner circumferential surface, but cuts a portion within the thickness of the hollow cylindrical body 112.

The cut surface may be divided into the first cut surface 114 and the second cut surface 116 based on the cutting purpose and direction.

The first cut surface 114 is a surface cut along the longitudinal direction (height direction) of the body 112 of the induction bushing 110, and at least one or more surfaces thereof are formed. 2 and 3, two first cutting surfaces 114 are formed in parallel to each other, but are not necessarily limited to the illustrated form. The reason for forming the first cut surface 114 is that it is advantageous to prevent the guide bushings 110 from turning together in the guide template by the rotation of the drill, and to reduce the width as it enters the space between the narrow teeth.

The second cut surface 116 is formed along a width direction perpendicular to the longitudinal direction, and at least one or more surfaces are formed to cut a middle portion of the body of the guide bushing 110 and 112 so that a step is formed at the upper and lower portions, respectively. . The second cut surface 116 is disposed in the direction orthogonal to the first cut surface 114, and has stepped portions at the upper and lower portions thereof. The second cut surface 116 has the induction bushing 110 extending in the longitudinal direction (up and down direction). It is to prevent the separation and separation from the guide template along.

In addition, the body 112 of the induction bushing 110 is formed with a slot 118 for longitudinally cutting the second cut surface 116 to penetrate the inner circumferential surface thereof. In the embodiment shown in FIGS. 2 and 3, two second cut surfaces 116 are formed to be perpendicular to and parallel to the first cut surface 114, and the slots 118 are either second cut surfaces 116. It is formed long along the longitudinal center to cut the upper step of the. In the illustrated embodiment, the slot 118 is formed to the lower stepped boundary surface of the second cut surface 116, the length of the slot 118 to be appropriately designed with the handle portion 154 of the inner bushing 150 to be described later. Can be.

The inner bushing 150 has a hollow cylindrical body 152 inserted into the inner circumferential surface of the induction bushing 110, and the induction bushing 110 and the body 112 have a slot 118 of the induction bushing 110. A handle portion 154 extending to protrude to the outside is provided. In addition, a grip portion 156 for holding with a finger is disposed at an end portion of the handle portion 154.

The inner diameter of the inner bushing 150 and the body 152 corresponds to the inner diameter of the induction bushing 110, and the inner bushing 150 for the induction bushing 110 is held by holding the grip portion 156 at the end of the handle portion 154. ) To combine and disengage At this time, the gripping portion 156 is circular, the gripping surface 158 is formed to be concave so that the tip of the thumb can be comfortably in close contact.

In addition, a through hole 160 may be formed in the center of the gripping portion 156, and the small inner bushing 150 is implanted into the neck during the implant surgery by tying a safety string (safety seal) to the through hole 160. When an accident occurs, the inner bushing 150 may be safely collected using the safe string.

In addition, in the illustrated embodiment, the width of the handle portion 154 is made smaller than the width of the slot 118 to allow the inner bushing 150 to rotate slightly, which is an angle that is easy to hold the grip portion 156. It is to be able to turn to. However, it is also possible to make each width the same so that the handle 154 fits in the slot 118.

In addition, as shown in FIG. 4, an embodiment in which the gripping portion 156 is narrow and elongated in accordance with the mesiodistal direction of the tooth, rather than circular, to reduce foreign body feeling in the mouth.

As such, the induction bushing assembly 100 of the present invention is easy to use because the inner bushing 150 having the handle portion 154 can be easily coupled to and separated from the induction bushing 110, and the inner bushing Since the handle portion 154 of the 150 is caught in the slot 118 and does not rotate during the drilling operation, there is no need to hold and work by hand. In addition, since the inner bushing 150 may be inexpensively manufactured by injection molding, there is no burden of discarding it after a single use, and thus there is a convenience in that it is not necessary to care for tolerance management by repeated use.

On the other hand, the induction bushing assembly 100 of the present invention by providing a variety of implant surgery information to the induction bushing 110 and the inner bushing 150 in a simple manner, the conventional uncomfortable and error-prone risk of referring to the printed output You can improve your approach.

First, information about the implant surgery may be provided through the inner bushing 150. Here, it is necessary to exclude the information about the implant surgery method as the character information, because the size of the guided bushing assembly 100 is very small because there is little character readability.

 Accordingly, the present invention considered a method of providing information about the implant surgery method in the form of a figure. 6 is a view showing an example of a figure indicating an implant surgery method, a circular designating a simple puncture surgery, a square specifying a bone graft surgery, a rhombus specifying a maxillary sinus elevation surgery, a bone transplant and a maxillary sinus elevation surgery It is possible to deliver accurate information about the implant surgery method with only four shapes of hexagons. For example, the inner bushing 150 of FIG. 6 is indicated by a hexagonal figure, which confirms that a complex surgery for bone graft and maxillary sinus ejaculation should be performed.

FIG. 5 shows two embodiments in which the figure specifying the above implant surgery method is displayed on the inner bushing 150, and FIG. 5 (a) shows the implant surgery method on the upper surface of the body 152 of the inner bushing 150. FIG. 5B illustrates a shape of the through-hole 160 of the grip portion 156 in the form of a circle or polygon indicating an implant surgery method. Shows the embodiment to make.

Therefore, the operator of the implant surgery can accurately grasp information about the implant surgery method by confirming the figure represented on the inner bushing 150.

In addition, the induction bushing assembly 100 having the above configuration may be more preferably configured as one set (hereinafter, referred to as "implant surgical drill set") together with one or more implant surgical drills DR. have. This is because the function of the guided bushing assembly 100 itself is to guide the drilling operation using the implant surgical drill (DR), because the guided bushing assembly 100 and the implant surgical drill (DR) is inseparably close relationship. to be. Here, one or more implant surgical drill (DR) may be provided in the form of a predetermined number of suits.

In order to be able to effectively use the organically constructed implant surgical drill set, it is much more advantageous to be able to easily and intuitively match the guided bushing assembly 100 and the implant surgical drill DR fitted therein. To this end, the implant surgical drill set of the present invention includes the following special configuration.

First, the guide bushing 110 may be provided with information about the length of the drill to be used as one of the information required during the implant surgery. The length information of the drill is also represented as a figure rather than a letter. As shown in FIG. 7, the length information of the drill is provided on the upper surface of the induction bushing 110 of the engraved figure 120 (circular in the illustrated embodiment). It is provided in numbers. The circular figure is more advantageous than the polygonal figure because it can secure the greatest readability in terms of the angle of view that a person looks at, and also has the advantage of being convenient in processing the figure.

On the body surface of the implant surgical drill (DR) provided by the applicant is shown one to five circular figures corresponding to the drill length of a total of five steps. In other words, the length of the implant surgical drill (DR) is set to five stages. The length of the implant surgical drill (DR) divided into five stages can cope with almost all implant procedures, and also a human can recognize immediately. The number of figures that exist is considering that the limit is about five. Through the configuration of varying the number of such figures, the operator of the implant surgery to accurately proceed with the operation in a simple manner to select the drill (DR) corresponding to the number of the intaglio figure 120 provided on the upper surface of the guide bushing (110) It becomes possible.

Here, although the embodiment of the present invention expresses the length information of the drill in the intaglio graphic 120, the intaglio is represented by the embossed graphic or the printed form because only the intaglio is formed because the ease of processing and the risk of damage are small. Of course it is also possible.

In addition, the induction bushing assembly 100 of the present invention may impart color information to each of the induction bushing 110 and the inner bushing 150 about the diameter of the drill to be used during the implant surgery. In response to this, the drill DR for the implant surgery itself may be configured to allow intuitive matching by making the circular figure displayed on the surface of the body as the color of the corresponding diameter.

 FIG. 8 summarizes two embodiments of color indicating the diameter of a drill to be used in implant surgery. This is based on the fact that there are two types of implants available on the market.

As shown in Figure 8, the first group of colors for specifying the diameter of the drill is six colors of black, yellow, white, red, blue, green, each color is sequentially 1.8, 2.3, 2.8, 3.3, 3.8, The diameter corresponds to a 4.3 mm drill. The second group has seven colors of gray, black, yellow, white, red, blue, and green, and one more gray is added to the first group. In the color of the second group, the diameters corresponding to the drills of 1.8, 2.3, 2.8, 3.0, 3.5, 4.0, and 4.2 mm are sequentially designated.

Corresponding to the color specifying the drill diameter, the guide bushing 110 and / or the inner bushing 150 may also be provided with a color corresponding to the diameter of the drill bushing to provide information on the diameter of the drill to be used. , The diameter information of the implant surgical drill (DR) can be intuitively confirmed through the color of the figure displayed on its surface. The combination of the induction bushing 110, the inner bushing 150 and the implant surgical drill DR to be used through this color matching can be made very easily without errors.

In particular, the diameter of the implant surgical drill provided as a suit is densely arranged at intervals of 0.5 mm or less as summarized above so that the drill can be accurately inserted into the guide bushing 110 or the inner bushing 150. Because it is difficult to do it, it is quite convenient to know the diameter of the drill simply by color without the need for a separate instrument to measure the diameter.

In addition, since the inner diameter of the induction bushing 110 is the final diameter, the diameter information of the drill for the induction bushing 110 may be used as the diameter information of the implant. This is because the diameter of the implant and the diameter of the implant correspond to each other through a tolerance relationship, so that the diameter of the implant to be placed in the drilled position of the drill of the specific diameter is necessarily determined as one.

Therefore, the diameter information of the implant can also be displayed in the color of FIG. 8. That is, by displaying a color on one surface of the implant, it is possible to specify the diameter of the implant to be placed in the hole of the alveolar bone formed by the diameter of the implant surgical drill DR. In addition, since the implants are individually packaged, it is also possible to mark the color of FIG. 8 on the packaging case of the implant.

9 is a cross-sectional perspective view showing an embodiment in which an inner tube 122 made of metal is inserted into an inner circumferential surface of the induction bushing 110. 9 illustrates a case in which the induction bushing 110 and the inner bushing 150 are manufactured by injection molding using a medical engineering plastic or the like for mass production and manufacturing cost reduction, and the induction bushing having a large diameter and a large friction area is manufactured. The inner circumferential surface of the 110 is reinforced by using an inner tube 122 made of metal.

Although not shown, it is also possible to reinforce the inner circumferential surface of the inner bushing 150 with a metal inner tube.

Here, when the inner tube 122 is applied to the induction bushing 110, a slot 124 corresponding to the slot 118 of the induction bushing 110 should be formed in the inner tube 122. In addition, the inner tube 122 may be fixed to the induction bushing 110 or the inner bushing 150 separately by bonding or fitting, and when manufactured by injection molding, the inner tube 122 may be inserted through injection molding. ) May be provided integrally.

10 and 11 are both views of the guide template (1000, 1000 ') to which the induction bushing assembly 100 of the present invention is applied, Figure 10 shows an embodiment of the maxillary guide template 1000, FIG. 11 shows one embodiment of the mandibular guide template 1000 ′.

The difference between the guide template (1000, 1000 ') for the maxillary and mandibular is that for the molar and premolar in the case of the maxillary guide template (1000), the slots (118) and the inner bushing (150) of the The handle portion 154 faces toward the lingual side and toward the buccal side for the rest of the tooth position, while in the case of the mandibular guide template 1000 ′, it is arranged to face the buccal position for all tooth positions. Arranging the induction bushing assembly 100 in this manner minimizes interference between the handle portion 154 and the grip portion 156 with oral tissues such as the tongue or cheek, and prevents the patient from feeling discomfort and causing nausea. This is to ensure that the implant surgery proceeds smoothly.

Here, even when the handle 154 of the slot 118 and the inner bushing 150 of the guide bushing 110 is disposed toward the buccal side, the grip portion 154 and the grip 156 press the strength of the inside of the gum or ball. It is more desirable to reduce.

To this end, the upper surface of the handle portion 154 forms a flat surface while the lower surface of the handle portion 156 toward the grip portion 156 to reduce the amount of interference by the handle portion 154 to press the gum and the inside of the ball can be reduced. have.

In addition, it is also preferable that the upper surface of the grip portion 156 is formed to protrude a little higher with respect to the upper surface of the handle portion 154 so that the grip portion 156 is located close to the inner center of the ball where the ball is most flexible. .

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
