种植体颈部设计的研究现状

Advances in the design of the transmucosal part of dental implant

口腔种植修复已成为缺失牙的首选治疗方案,种植体的成功不仅需要良好的骨结合,良好的软组织封闭也尤为重要。目前,种植体骨结合方面的研究已趋于成熟,而种植体颈部设计对软硬组织的影响还有待研究。笔者将本课题组对种植体颈部结构设计的研究情况结合国际上的前沿研究进行探讨,按照种植体颈部设计与边缘骨吸收、软组织封闭的形成和菌斑粘附形成的关系进行评述。

Nowadays, dental implant is the first therapeutic choice of the edentulous patients. A firm functional soft tissue seal between the transmucosal part of implants and the surrounding soft tissues is significant to the long-term survival of the implant as well as the stable osseointegration. There are many research on the osseointegration, but less in the transmucosal part of the implant. In this review, we combined the implant neck design of our own with the interna-tional study in this field, in order to discuss the relationship between the implant neck design and the marginal bone loss, interact with the soft tissue, the antibacterial activity.
