Mandibular gingival flap stretching fixation clamp

Abstract

The invention relates to a mandibular gingival flap stretching fixation clamp which has simple structure, is convenient to use and is used in gingival flap implant operation. When in use, a left alveolar bone fixing arm and a right alveolar bone fixing arm clamp the alveolar bone from the left and right sides, a left gingival flap stretching arm and a right gingival flap stretching arm can move oppositely, gingival flap stretching plates on the left and right gingival flap stretching arms stretch the gingival flap to the left and right sides so that the surgical site on the top of the alveolar bone can be fully exposed for operation, the dental drill for holing and the implant can not contact the gingival soft tissue, and the soft tissue can not be carried into the cavity to affect synosteosis; and after the gingival flap is stretched by the stretching fixation clamp, the hands of the doctor can be free and the operation can be performed smoothly. The mandibular gingival flap stretching fixation clamp is mainly used to stretch and fix the gingival flap after gingival is flapped in the mandibular teeth implant operation and can also be used in the mandibular teeth alveolar ridge trimming and forming operation.

Description

technical field [0001] The invention relates to a medical device, in particular to a mandibular gingival flap expansion clamp. Background technique [0002] Dental implant is a new technology developed rapidly in stomatology in recent years. It refers to implanting an implant (artificial tooth root) with good biocompatibility with the human body into the jawbone of the missing tooth through surgery, and after a period of healing, the artificial tooth root is then fitted with a denture. (dentures), to restore missing teeth, has the advantage of not damaging healthy adjacent teeth. As a special way of oral restoration, dental implant has brought good news to patients with missing teeth. It is known as "the third set of human teeth" and solves some problems that cannot be solved by conventional restoration. In recent years, dental implant technology has been widely used in patients with various dentition defects and edentulousness, and has gradually become the preferred resto...

AI Technical Summary

Problems solved by technology

Due to the good elasticity of the gingival soft tissue, the peeled mandibular gingival flap can easily return to the surface of the alveolar bone, which seriously affects the doctor's surgical field of view and operation

Generally speaking, surgeons often use sutures to pass through the mandibular gingival flap and fix it with vascular forceps or directly suture and fix it on the buccal mucosa. This will not only easily cause gingival tearing, but also the exposure of the operative field is often insufficient, and the hole is prepared. When the instrument is drilled and the implant is placed, it is easy to contact the gum, which may bring soft tissue into the implant cavity and affect osseointegration

In addition, during the operation, the mandibular gums can also be pushed away to both sides with a periosteal stripper and other instruments. Although this will not cause the gums to tear, it requires two hands of the doctor, which is inconvenient to operate, and the instruments Tendency to slip off the gingival flap, allowing drilling instruments and implants to come into contact with the gingiva or the rotating drill to damage the gingival tissue
