Drill device for dental implant treatment {DEVICE OF DRILL FOR DENTAL IMPLANT PROCEDURE}

The present invention relates to a drill device for dental implant surgery, and more particularly, in the gingiva covering the cover screw coupled to the fixture in the second operation after the primary implant operation during dental implant operation, corresponding to the implant placement position. It relates to a drill device for dental implant surgery that can prevent nerve damage by cooling the perforated area by piercing the area without incision and at the same time guiding and supplying washing water to the perforated site by gravity during the gingival perforation process.

In general, the implant means a substitute that can replace the human tissue when the original human tissue is lost, but in dentistry refers to the implantation of artificially made teeth. In other words, it is a procedure that restores the function of teeth by implanting a fixture made of titanium, etc., which does not have a rejection reaction in the human body, in the alveolar bone from which the teeth have escaped, and then fixing the artificial teeth to replace the lost root.

In the case of general prostheses or dentures, the surrounding teeth and bones are damaged over time, but implants can prevent damage to the surrounding dental tissues and can be used stably because there is no secondary cause of caries. In addition, since the implant has substantially the same structure as a natural tooth, there is no pain or foreign body feeling in the gums, and there is an advantage that it can be used semi-permanently if well managed.

Currently, the implant procedure is performed in order to implant a fixture in the alveolar bone with missing teeth. When the bone thickness is thin, maxillary sinus elevation and bone graft are performed in parallel to form an implantation groove using a tool such as a drill after implantation. After implanting the fixture, after finishing bonding with a cover screw, after the first operation to suture the gingiva, and after a few months for the second operation, after removing the gingival perforation and periosteum, remove the cover screw, and then attach the abutment to the fixture and abutment The implant operation is completed by combining the artificial tooth with the ment.

At this time, in order to couple the abutment to the fixture, the seat surface, that is, the outer gingiva of the cover screw, must be drilled for a predetermined section to match the upper surface of the fixture. It was removed by rotation.

Accordingly, the incised gingival debris enters the interior of the fixture and becomes a cause of infection or a hindrance during the procedure. There was a problem that did not heal and lasted for a long time.

In addition, the temperature of the incision site increases due to repeated incisions, which may cause nerve damage.

Specifically, as shown in FIG. 8 , the tissue punch 3 for dental implants rotates in one direction and is guided according to the height of the adjacent teeth and the spacing between the adjacent teeth by the guide 1 for dental implant surgery to cut the gingiva 42 . It is possible to make the first hole by punching the guide tissue without incision.

For example, when implanting one tooth, when the adjacent tooth spacing (D11) is 9mm and the length of the fixture (F) is 10mm, the diameter (D5) is 3.2mm for dental implant tissue punch (3) Using a drill device for dental implant surgery in which the outer guide part 20 having a diameter (D4) of 9 mm is combined with the position corresponding to the placement position of the dental implant, the gingiva (42) can be punched with guide tissue without incision. have. That is, by using the guide 1 for dental implant surgery used in the primary procedure, it is possible to accurately find the dental implant placement position between adjacent teeth and drill the gingiva 42 without incision.

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

For example, when one tooth is implanted, when the adjacent tooth spacing (D11) is 9mm and the length of the fixture (F) is 10mm, the diameter (D5) is 4.2mm for dental implant tissue punch (3) And, by using a drill device for dental implant surgery in which the outer guide part 20 having a diameter (D4) of 9 mm is combined, the position corresponding to the placement position of the dental implant is confirmed, and the gingiva 42 is enlarged by tissue punching. It is possible to form the gingival perforation 44 without cutting 42). That is, by using the guide 1 for dental implant surgery used in the primary procedure, it is possible to accurately find the dental implant placement position between adjacent teeth and drill the gingiva 42 without incision.

At this time, as shown in FIG. 10, washing water can be supplied to cool the tissue punch 3 for dental implants that is heated by friction with the gingiva 42 during the punching operation of the tissue punch 3 for dental implants. have. The supplied washing water moves through the space 200 without escaping to the outside by the outer guide part 20 of the guide for dental implant procedure 1 that guides the washing water and passes through the through hole 102, It is smoothly supplied to the gingiva 42 through the punch hole 36 of the tissue punch 3 for implants, thereby preventing necrosis of the perforated portion 44, and thus can safely perform perforation.

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

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

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

Conventionally, in order to couple the abutment to the fixture (F), the outer gingiva 42 of the cover screw (C) is cut using an incision tool such as a scalpel to find a position corresponding to the implantation position of the dental implant. ) was incised and the gums were peeled off to find the fixture (F). Accordingly, if the gingiva (42) is incised and spread out, then the fixture (F) is found, the cover screw (C) is removed, the abutment is combined, and a secondary operation is performed to suture the area, suture during the dissection process. The pain in the affected area was maintained for a long time, and the recovery rate was slow due to swelling, which increased the patient's discomfort.

In addition, the remnants of the incised gingiva 42 enter the inside of the fixture (F) and become a cause of infection or a stumbling block during the procedure. If the teeth are not clean, the surgical wound cannot heal well and has a long-lasting problem.

However, as in this embodiment, by guiding the tissue punch 3 for dental implants using the guide 1 for dental implant surgery used in the primary procedure according to the height of the adjacent teeth and the spacing between adjacent teeth, the dental implant placement position is determined. By confirming, the gingiva 42 can be perforated through the guide tissue punching and enlarged tissue punching without incision to form the gingival perforation 44 . That is, by perforating the gingiva 42 using the tissue punch 3 for dental implants, there is no exfoliation of the gingiva 42, and the gingiva 42 is simply punched without a suturing process according to the exfoliation of the gingiva 42. can do.

Furthermore, it is possible to guide the tissue punch 3 for dental implants while guiding the tissue punch 3 for dental implants in the correct direction by using the guide 1 for dental implant procedures so that the tissue punch 3 for dental implants does not move from side to side. Accordingly, the tissue punch 3 for dental implants is supported without shaking by the guide 1 for dental implant procedures, so that the dental implants of the alveolar bone 40 are placed in the correct position, direction, and depth. work can be done.

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

First, when two teeth are implanted as shown in FIG. 11( a ), the width of the opposite tooth corresponding to the tooth to be treated can be checked.

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

In the first operation, using the outer guide part 20 with a diameter (D4) of 9 mm and the outer guide part 20 with a diameter (D4) of 10 mm, the fixture (F) was implanted in the alveolar bone (40) in the gums. After that, the primary operation for suturing the gingiva 42 can be performed by combining the cover screw (C).

After the first operation, several months later, during the second operation, the gingiva 42 is vertically cut without incision using a dental implant drilling device in which a dental implant guide (1) and a tissue punch (3) for dental implants are combined. It is possible to perform a perforation operation to form a perforated gingival perforation (44).

For example, in response to the spacing (D21) of the first tooth of 9mm, the diameter (D5) is 3.2mm for dental implant tissue punch (3) and the diameter (D4) is 9mm of the outer guide part 20 is combined A dental implant procedure in which guide tissue punching is performed using a drill device for dental implant surgery, and a tissue punch 3 for dental implants with a diameter (D5) of 4.2 mm and an outer guide unit 20 with a diameter (D4) of 9 mm are combined It is possible to form the gingival perforation 44 by enlarged punching using a drilling device.

After removing the cover screw (C) coupled to the fixture (F) of the portion where the first tooth is to be formed through the gingival perforation 44, a cylinder guide indicating the dental implant placement position of the first tooth is coupled And, by combining the guide (1) for dental implant surgery having a diameter (D4) of 9 mm, it can be positioned instead of the interval (D21) between the first teeth.

Next, as shown in FIG. 11( b ), dental implants are placed in the interval D22 between the second teeth based on the guide 1 for dental implant surgery coupled with the cylinder guide positioned at the interval D21 between the first teeth. Using a drill device for dental implant surgery in which the surgical guide (1) and the dental implant tissue punch (3) are combined, the position corresponding to the dental implant placement position is checked and the gingiva (42) is drilled without incision to make the gingival perforation. (44) can be performed to form a drilling operation. That is, by using the guide 1 for dental implant surgery used in the primary procedure, it is possible to accurately find the dental implant placement position between adjacent teeth and drill the gingiva 42 without incision.

For example, in response to the gap (D22) of the second tooth of 10mm, the tissue punch 3 for dental implants having a diameter (D5) of 3.2mm and the outer guide part 20 having a diameter (D4) of 10mm are combined. A dental implant procedure in which guide tissue punching is performed using a drill device for dental implant surgery, and a tissue punch 3 for dental implants with a diameter (D5) of 4.2 mm and an outer guide unit 20 with a diameter (D4) of 10 mm are combined It is possible to form the gingival perforation 44 by enlarged punching using a drilling device.

On the other hand, since drilling is started in a state where the lower surface of the guide 1 for dental implant surgery is seated on the alveolar bone 40, there is no difference in the gap depending on the depth of the perforation that may be caused by the step of the tooth, so the cutting depth does not occur. Nerve damage, etc., may not occur because the condition is precisely limited to the extent desired by the operator.

At this time, washing water may be supplied to cool the tissue punch 3 for dental implants, which is heated by friction with the perforated portion. The supplied washing water moves through the space 200 without escaping to the outside by the outer guide part 20 of the guide for dental implant procedure 1 that guides the washing water, passes through the through hole 102, and passes through the dental implant. It is smoothly supplied to the perforated site through the punch hole 36 of the tissue punch 3 for use, thereby preventing necrosis of the perforated site, thereby making it possible to safely perform perforation work. At this time, the washing water supplied to the perforated portion through the space 200 of the outer guide portion 20 and the through hole 102 cools the perforated portion so that the temperature of the perforated portion does not become excessively high due to frictional heat during the perforating process. It plays the role of cooling water to prevent necrosis of the perforated site, and at the same time, foreign substances generated during the perforation process, for example, intraoral tissue or fragments of the alveolar bone 40, are smoothly discharged from the perforated site through the through hole 102. can be made to be discharged.
