Description

Surgical guide for implant surgery with preserved labial roots

technical field

The utility model relates to the technical field of dental implantation, in particular to an implantation operation guide plate for retaining the root of the labial side.

Background technique

The labial alveolar bone resorption after anterior tooth implant restoration is a common clinical complication, which seriously affects the effect of aesthetic restoration and brings great distress to doctors and patients. Retaining part of the labial root can maintain the integrity of the physiological connection between the root and the bundle bone, maintain the volume of the alveolar ridge, offset the collapse of the alveolar bone after tooth extraction, and reduce the resorption of the labial alveolar bone. At present, doctors mainly use bare hands to cut the root, which often causes accidental injury to the surrounding alveolar bone, the size of the retained root does not match the expected, the section of the retained root is not neat, and even causes the retained root to loosen and cause the failure of the operation. It seriously affects the prognosis of this treatment.

Chinese patent document: CN110464494A, publication date: 2019.11.19, discloses a dental implantation guide system and inspection method, the implantation guide system includes a transplant socket hole preparation guide and a root hole preparation guide, and the transplant socket hole preparation guide has implantation Guide hole, the outline of the transplant guide hole is consistent with the outline of the neck line of the transplanted tooth, and the transplant guide hole coincides with the transplant direction of the tooth to be transplanted; the root preparation guide plate has a guide sleeve and a drill sleeve, and the axes of the guide sleeve and the drill sleeve are parallel to the direction of the implant. The direction of the target root of the tooth to be transplanted is the same; the implant guide hole and the drill sleeve correspond to the same alveolar position.

The technical solution is as follows: simulating the preparation of the transplant socket on the plaster model, and using the transplant guide plate to accurately locate the position of the hole that needs to be prepared for the root of the transplanted tooth; after preparing the hole, remove the tooth to be transplanted, clean it, and check the buccal-lingual To the position, the implanted tooth is implanted; using the digital software, the precise position of the autologous tooth implantation is simulated on the three-dimensional software before the implantation. The size of the implant guide hole is determined according to the shape and size of the implanted tooth; the implant guide plate made by 3D printing is used.

In addition, the main purpose of this technical solution is to prepare a suitable implant space, while the main purpose of the present application is to precisely cut teeth. The two are completely different in purpose.

To sum up, there is an urgent need for a labial root-retaining method that can help doctors determine the angle and depth of cutting teeth during surgery, prevent unnecessary damage to alveolar bone, and determine the location and direction of implants to achieve precise teeth cutting and precise implantation. The implant surgical guide has not been reported so far.
