前牙种植修复体穿龈形态设计的研究进展

Progress in emergence profile design for implant restorations in the esthetic area

在美学区的种植修复中,修复体的形态设计对美学效果有重要影响。龈缘以下修复体的形态,即穿龈形态对种植修复的软组织美学和健康均至关重要。前牙种植修复体的穿龈形态设计方案、适应证、影响因素等相关研究较少且观点不一。多数种植修复体形态设计的理论支持来源于天然牙修复,但种植体和天然牙的修复体设计并不完全相同。本文主要综述前牙种植修复后穿龈形态的设计,以期为临床医师提供参考。

In the implant restoration of aesthetic area,the contour design of restoration has an important influence on the esthetic effect.The shape of subgingival portion of prosthesis,that is,the emergence profile plays an important role in aesthetic effect and health of the soft tissue.There are few studies on the contour design,indications,influencing factors of the emergence profile of the implant prosthesis.Most of the theoretical support for the contour design of implant restorations comes from the natural teeth restoration,but the design of implant and natural teeth restorations is not the same.This paper mainly reviews the design of emergence profile for implant restorations in the esthetic area,and provides and provides reference for clinical doctors.
