Problems solved by technology

In the prior art, when carrying out attached gingiva transplantation, the grafted gingiva is sutured with thread and waits for healing, but the gingiva sutured with thread is poorly fixed, and it is easy to cause the sutured wound to fail to heal, and even the suture is torn to cause necrosis of the gingiva and mucosal tissue

Embodiment Construction

[0023] Such as figure 1 The fixed guide plate for gingiva grafting around the dental implant has screw holes for the guide plate fixture 4 to pass through, and the bottom surface of the guide plate is matched with the bone surface of the patient's alveolar bone. The guide plate fixing part 4 is all the same with the existing gingiva former except that the length of the screw rod is different.

[0024] A method for making a fixed guide plate for gingiva grafting around a dental implant comprises the following steps:

[0025] 1) Obtain the oral data of the patient after the first-stage operation by scanning, and establish a three-dimensional oral model of the patient. The three-dimensional oral model contains the data of the patient's alveolar bone, and the implant 3 is implanted in the alveolar bone 2;

[0026] 2) Pick up the curved surface of the alveolar bone where the gingiva needs to be transplanted, thicken the curved surface of the alveolar bone, and form a preliminary m...

Abstract

A method for manufacturing a dental implant gingival graft fixing system includes: establishing three-dimensional alveolar bone data of a patient, wherein an alveolar bone comprises a healed implant; thickening an alveolar bone curve surface to form a preliminary model of a guide plate; making screw holes in the preliminary model to form a fixing guide plate model; establishing a three-dimensional model of a guide plate fixing part; making the bottom surface of the fixing guide plate model into a plane to form a mucous membrane taking guide plate model; making the fixing guide plate model into a tangible fixing guide plate, and molding the guide plate model. The dental implant gingival graft fixing guide plate is provided with screw holes, and the bottom face of the guide plate matches with the bone surface of the alveolar bone of to-be-implanted gingiva. The dental implant gingival graft fixing system comprises the fixing guide plate, the guide plate fixing part and the implant. When the guide plate fixing part and the implant are connectedly screwed in place, a cap portion of the guide plate fixing part is abutted against the guide plate, and the distance between the guide plate and the alveolar bone is about 3mm. Implanted gingiva fixation can be realized while implanted gingiva survival rate is increased during gingival graft in dental implant two-stage operation.

Description

technical field [0001] The invention relates to the field of dental implant medical devices in the Department of Stomatology, in particular to a guide plate for fixing the gingiva transplantation of dental implants, a method for making the guide plate and a fixing system during dental implant surgery. Background technique [0002] Dental implants refer to a method of restoring missing teeth based on implants implanted in the alveolar bone to support and retain tooth restorations. Dental implants have become the preferred restoration method for more and more patients with missing teeth because they can achieve a restoration effect that is very similar to natural teeth in terms of function, structure and aesthetics. [0003] Dental implant surgery is divided into 3 steps: 1. One-stage surgery: implant the implant into the alveolar bone in the edentulous area by surgical means, wait for the implant to be osseointegrated with the alveolar bone, and the implant is located in the ...
