摘要
牙齿缺失会导致功能和美学方面的缺陷,传统上应用活动义齿或者固定义齿进行修复。近些年种植体给我们提供了一个更优化的选择,它们被植入颌骨后可以支撑上部的修复体,从而恢复缺失牙。尽管种植体有极高的成功率,但也偶有边缘性骨吸收导致种植体失败的情况出现。为了获得良好的骨结合和种植体稳定性,学者们针对不同的骨质类型和临床条件设计了多种的种植体颈部表面结构。本文就种植体光滑颈圈这一设计及应用进展作一综述,主要介绍了光滑颈圈的几何结构,光滑颈圈与边缘性骨吸收的关系,光滑颈圈与种植体周围炎的关系。
Missing teeth may result in a functional and aesthetic deficit and have traditionally been replaced with dentures or bridges.Dental implants offer an alternative.They are inserted into the jawbones and used to support dental prostheses.Although dental implants show high survival rates,complications occasionally lead to marginal bone loss which could result in implant failure.So as to facilitate obtaining adequate osseointegration and stability,a large number of implant neck surface characteristics were designed for different bone types and clinical situations.There is,however,a paucity of well-presented reviews addressing the influence of the implant neck design on bone and soft tissue parameters.Thus,in this review,we made a detailed discussion about smooth-collared implant,including smooth collar geometry and the relationship between smooth collar and hard and soft tissue.
