骨引导再生技术在牙种植中的应用

骨引导再生技术是目前在牙种植外科中常用的一种增加牙槽骨骨量的重要手段。该技术通过在骨缺损处放置屏障膜，维持膜下稳定的空间，阻止结缔组织长入，促进骨组织优先生长。近年来，各种屏障膜和各类骨移植材料不断涌现，此项技术的临床应用范围也在不断拓展。文章对膜材料的种类和特性以及该项技术在牙种植中的应用现状进行了综述。

Application of guided bone regeneration technique in dental implantation

Guided bone regeneration technique (GBR) is regarded as one of the most important methods to increase the bone amount of alveolar ridge, which is often recommended to be applied in the dental implantation surgery. Barrier membrane is utilized in GBR technique to cover the bone defect and create a secluded space, which prevents the connective tissue from growing into the space and facilitates the growth priority of bone tissue. In recent years, along with the emerging of different kinds of barrier membranes and bone grafting materials, the scope of clinical application of this technology is continuously expanded. This article reviews the classification and property of the membranes and the application situation of guided bone regeneration technology in the field of dental implantation.
