Protection structure of alveolar bone defect bone grafting region

Abstract

The embodiment of the invention relates to an oral medical appliance, and discloses a protection structure of an alveolar bone defect bone grafting region. A protection structure of the alveolar bone defect bone grafting region comprises a shield film and retention pins, wherein the shield film is used for covering and sealing the alveolar bone defect bone grafting region; the retention pins are used for fixedly connecting the shield film and the jaw; a plurality of retention pins can be installed. The shield film and each retention pin are made of degradable alloy materials capable of being absorbed by the human body. Compared with the prior art, the shield film and the plurality of retention pins jointly provide stable regeneration space for the bone regeneration; the shield film and the retention pins can be slowly degraded and absorbed by the human body, so that the shield film and the retention nails can be gradually degraded and absorbed while protecting the alveolar bone defect bone grafting region; the bone tissue regeneration is promoted, so that the injury and the risk due to that fact that the shield film and retention pin are taken out by secondary operation can be avoided.

Description

technical field [0001] The embodiment of the present invention relates to an oral medical device, in particular to a protection structure for a bone graft area of ​​an alveolar bone defect. Background technique [0002] The human alveolar bone continues in the body of the upper and lower jaws. It is an important maxillofacial support structure that supports tooth eruption and masticatory force transmission. It also stabilizes the shape and function of the dental arch, realizes language, breathing, and chewing functions, and maintains the maxillofacial Aesthetics, etc. have an important impact. Chronic inflammation, trauma, tumors, developmental defects and other factors can lead to alveolar bone tissue defects, resulting in abnormal oral and jaw function and facial appearance. For cases of tooth loss and severe local alveolar bone shortage, bone tissue augmentation surgery is often required in clinical practice to ensure the smooth progress of subsequent dental implant rest...

AI Technical Summary

Problems solved by technology

The inventors have found that there are at least the following problems in the prior art: when the absorbable barrier membrane is used, the mechanical strength is insufficient, and a stable regeneration space cannot be provided for bone regeneration, which often leads to treatment failure at the site of high local tissue pressure

However, when a non-absorbable barrier membrane is used, after bone grafting, a second operation is required to remove the non-absorbable membrane and membrane nails, which will cause greater trauma to the patient.
