In this embodiment, the locking groove 38 is disclosed as having two locking grooves, but is not limited thereto, and may include at least one locking groove.

It is possible to adjust the height of the dental implant procedure guide (1) coupled by such a locking groove (38).

For example, according to the height of the adjacent tooth, by being selectively fastened to the locking groove 38, the dental implant tissue punch 3 is guided and the portion corresponding to the cover screw C coupled to the fixture F is removed. It can be precisely perforated without incision.

The operation of the drill device for dental implant surgery according to an embodiment of the present invention having such a structure is as follows. 8 is a view for explaining a guide tissue punching step of a drill device for dental implant surgery according to an embodiment of the present invention, and FIG. 9 is an enlarged tissue punching of a drill device for dental implant surgery according to an embodiment of the present invention. It is a view for explaining steps, and FIG. 10 is a view for explaining a state of use of a drill device for dental implant surgery according to an embodiment of the present invention.

First, during a dental implant procedure, the fixture (F) is implanted in the alveolar bone (40) in the gum, and then the primary surgery of suturing the gingiva (42) by combining the cover screw (C) can be performed.

After the first surgery, several months later, during the second surgery, the dental implant guide (1) and the dental implant tissue punch (3) are combined to drill the gingiva (42) without incision to perform vertical drilling. It is possible to perform the perforation work to form the gingival perforation 44.

Specifically, as shown in FIG. 8 , while the dental implant tissue punch 3 rotates in one direction, the guide 1 for dental implant surgery guides the gingiva 42 according to the height of adjacent teeth and the gap between adjacent teeth. The first hole can be made by punching the guide tissue without incision.

For example, when one tooth is implanted, the adjacent tooth gap (D11) is 9 mm, and the length of the fixture (F) is 10 mm, the tissue punch (3) for tooth implant having a diameter (D5) of 3.2 mm Guide tissue punching can be performed without incision of the gingiva 42 by checking the position corresponding to the placement position of the dental implant using a drill device for dental implant surgery in which the outer guide part 20 having a diameter D4 of 9 mm is combined. there is. That is, by using the dental implant procedure guide 1 used in the first procedure, it is possible to accurately locate the dental implant placement position between adjacent teeth and perforate the gingiva 42 without incision.

After the primary guide tissue punching, as shown in FIG. 9 , the dental implant tissue punch 3 rotates in one direction and is guided by the dental implant guide 1 according to the height of the adjacent teeth to form the gingiva 42. It is possible to form a gingival perforation 44 by secondarily expanding and punching the guide without incision.

For example, in the case of implanting one tooth, when the adjacent tooth gap D11 is 9 mm and the length of the fixture F is 10 mm, the tissue punch 3 for tooth implant having a diameter D5 of 4.2 mm And, by using a drill device for dental implant operation in which the outer guide portion 20 having a diameter (D4) of 9 mm is coupled, the position corresponding to the placement position of the dental implant is confirmed, and the gingiva 42 is enlarged and tissue punched to obtain a gingiva ( The gingival perforation 44 can be formed without the incision of 42). That is, by using the dental implant procedure guide 1 used in the first procedure, it is possible to accurately locate the dental implant placement position between adjacent teeth and perforate the gingiva 42 without incision.

At this time, as shown in FIG. 10, washing water may be supplied to cool the dental implant tissue punch 3, which becomes hot due to friction with the gingiva 42 during punching of the dental implant tissue punch 3. there is. The supplied washing water moves through the space part 200 and passes through the through hole 102 without escaping to the outside by the outer guide part 20 of the guide 1 for dental implant procedure that guides the washing water, It is smoothly supplied to the gingiva 42 through the punch hole 36 of the tissue punch 3 for implantation, thereby preventing necrosis of the perforation site 44 so that perforation work can be performed safely.

After the perforation work is completed, the cover screw (C) coupled to the fixture (F) exposed to the perforated portion 44 formed without incision may be removed.

After removing the cover screw (C) coupled to the fixture (F), an abutment (not shown) may be coupled to the top of the fixture (F).

*Finally, the dental implant procedure can be completed by combining the artificial tooth with the abutment.

Conventionally, in order to combine the abutment to the fixture (F), the outer gingiva 42 of the cover screw (C) is cut using a cutting tool such as a scalpel to find a position corresponding to the placement position of the dental implant (42). ) was incised and the gum was peeled off to find the fixture (F). Accordingly, after incising and opening the gingiva 42, finding the fixture (F), removing the cover screw (C), combining the abutment, and then performing a secondary surgery to suture the area, suturing in the dissection process Pain in the affected area was maintained for a long time, and the recovery rate was slow due to swelling, increasing the patient's discomfort.

In addition, the remnants of the incised gingiva 42 enter the inside of the fixture F and cause infection or an obstacle during the procedure, and it is not easy to incise the exact area with a scalpel, etc. If this is not clean, the procedure wound does not heal well and a long-lasting problem occurred.

However, as in the present embodiment, the dental implant placement position is determined by guiding the dental implant tissue punch 3 using the dental implant procedure guide 1 used in the first procedure according to the height of the adjacent teeth and the interval between the adjacent teeth. After confirmation, the gingiva 42 may be perforated through guide tissue punching and enlarged tissue punching without cutting the gingiva 42 to form the gingival perforation 44 . That is, by punching the gingiva 42 using the tissue punch 3 for dental implant, there is no separation of the gingiva 42, and there is no suturing process according to the separation of the gingiva 42, and the gingiva 42 is simply perforated. can do.

Furthermore, while guiding the dental implant tissue punch 3 in an accurate direction using the dental implant procedure guide 1, the dental implant tissue punch 3 may be guided so as not to shake from side to side. Accordingly, the dental implant tissue punch 3 is supported without shaking by the dental implant procedure guide 1, so that the dental implant of the alveolar bone 40 is placed in the correct position, direction, and depth of the gingiva 42. work can be done.

11 is a view for explaining a step of using a drill device for dental implant surgery according to another embodiment of the present invention, FIG. 11 (a) is a view for explaining a state before forming a perforation on the gingiva, FIG. (b) is a view for explaining a state in which a gingival perforation is formed.

First, as shown in FIG. 11 (a), in the case of performing implant treatment on two teeth, it is possible to check the width of the opposite tooth corresponding to the tooth to be operated on.

For example, the distance D21 of the first teeth may be 9 mm, and the distance D22 of the second teeth may be 10 mm.

In the first operation, a fixture (F) is implanted into the alveolar bone 40 in the gum using the outer guide part 20 having a diameter D4 of 9 mm and the outer guide part 20 having a diameter D4 of 10 mm. After that, the first operation of suturing the gingiva 42 by coupling the cover screw C may be performed.

After the first surgery and the second surgery several months later, the gingiva 42 is vertical without incision using a drill device for dental implant surgery in which the guide for dental implant surgery (1) and the tissue punch for dental implant (3) are combined. A punching operation for forming the gingival punching 44 by punching may be performed.

For example, corresponding to the distance D21 of the first teeth of 9 mm, the tissue punch 3 for dental implant having a diameter D5 of 3.2 mm and the outer guide portion 20 having a diameter D4 of 9 mm are combined. Guide tissue punching using a drill device for dental implant surgery, and dental implant treatment in which a tissue punch (3) for dental implants with a diameter (D5) of 4.2 mm and an external guide part (20) with a diameter (D4) of 9 mm are combined. The gingival perforation 44 may be formed by enlarged punching using a drilling device.

Remove the cover screw (C) coupled to the fixture (F) of the part where the first tooth is to be formed through the gingival perforation 44, and then combine a cylinder guide indicating the dental implant placement position of the first tooth. And, by combining the guide 1 for dental implant procedure having a diameter (D4) of 9mm, it can be positioned instead in the gap (D21) of the first tooth.

Next, as shown in FIG. 11 (b), based on the guide 1 for dental implant procedure combined with the cylinder guide located in the gap D21 of the first teeth, the dental implant is located in the gap D22 of the second teeth. Using a drill device for dental implant surgery in which the guide for treatment (1) and the tissue punch for dental implant (3) are combined, the position corresponding to the placement position of the dental implant is checked and the gingiva 42 is perforated without incision to perforate the gingiva. It is possible to perform a punching operation to form (44). That is, by using the dental implant procedure guide 1 used in the first procedure, it is possible to accurately locate the dental implant placement position between adjacent teeth and perforate the gingiva 42 without incision.

For example, corresponding to the distance D22 of the second teeth of 10 mm, the tissue punch 3 for dental implant having a diameter D5 of 3.2 mm and the outer guide portion 20 having a diameter D4 of 10 mm are combined. Guide tissue punching using a drill device for dental implant surgery, and dental implant treatment in which a tissue punch (3) for dental implants with a diameter (D5) of 4.2 mm and an outer guide part (20) with a diameter (D4) of 10 mm are combined. The gingival perforation 44 may be formed by enlarged punching using a drilling device.

On the other hand, since drilling starts with the lower surface of the guide 1 for dental implant procedure seated on the alveolar bone 40, the difference in the gap according to the depth of the perforation that can occur due to the step of the tooth does not occur, thereby reducing the cutting depth. Since is precisely limited to the extent desired by the operator, nerve damage or the like may not occur.

At this time, washing water may be supplied to cool the dental implant tissue punch 3, which becomes hot due to friction with the perforated area. The supplied washing water moves through the space part 200 without escaping to the outside by the outer guide part 20 of the guide 1 for dental implant procedure, which guides the washing water, and passes through the through hole 102 to implant dental implants. Through the punch hole 36 of the tissue punch 3, it is smoothly supplied to the perforated area to prevent necrosis of the perforated area so that perforation work can be performed safely. At this time, the washing water supplied to the perforated area through the space part 200 of the outer guide part 20 and the through hole 102 cools the perforated area so that the temperature of the perforated area does not become excessively high due to frictional heat during the perforation process. It serves as cooling water to prevent necrosis of the perforated area, and at the same time, foreign substances generated during the perforation process, such as oral tissues or fragments of the alveolar bone 40, are smoothly removed from the perforated area through the through hole 102. can be let out.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art to which the present invention pertains can be implemented in other specific forms without changing the technical spirit or essential features of the present invention. you will be able to understand Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
