Definitions

  • a dental implant is a dental treatment that restores the function of natural teeth by implanting an implant body (fixture) made of a biocompatible material such as titanium on the jawbone of a tooth defect or a tooth extraction area. If the alveolar bone to which the fixture is to be implanted due to tooth detachment or inflammation for a long time does not have a sufficient thickness (quantity), the implanted fixture cannot be sufficiently supported and pain may occur due to the proximity of the fixture and the nerve. Guided bone regeneration (GBR) is performed to promote bone tissue regeneration by implanting bone graft materials into the missing alveolar bone before or at the same time.

Abstract

La présente invention concerne une membrane barrière médicale, qui est placée entre les gencives et un os alvéolaire, afin de couvrir un matériau de greffe osseuse greffé dans l'aire de l'os alvéolaire manquant ou afin de régénérer une gencive attachée, et plus précisément, une membrane barrière médicale comprenant : une partie poinçonnée dans laquelle sont formés des pores fins permettant le passage du sang ; et une partie d'étanchéité dont la surface entière est entourée par la partie poinçonnée et n'étant pas dotée de pores fins de taille quelconque, la partie d'étanchéité empêchant des substances étrangères introduites par une aire suturée ouverte sur les gencives ayant été séparée (par exemple, une aire dans la aire de suture ayant été séparée) d'entrer dans une aire régénérée sur l'os alvéolaire, et empêchant un os greffé de se disloquer, permettant ainsi d'améliorer l'efficacité de génération de l'os alvéolaire.
