[Influencing factors and esthetic considerations of emergence profile of implant dentures in the anterior teeth area].

The emergence profile of implant restorations plays an important role on the final esthetic outcome. This article intends to review the emergence profile design of implant restorations in the anterior teeth area, and analyse the factors that affect the emergence profile of implant restorations: implant neck design (non-platform-switching bone level implants, platform-switching implants, and soft tissue level implants), implant position and inclination (implant depth, buccal-lingual position, mesiodistal position, and axial inclination), the type of the abutment, quality and quantity of peri-implants soft tissues. The article aims to provide clinical guidelines for the emergence profile design of implant prostheses based on existing literatures and clinical experiences.前牙区种植义齿的穿龈轮廓对最终的美学效果具有重要影响。本文对前牙区种植义齿穿龈轮廓设计进行评述，分析影响种植义齿穿龈轮廓的因素：种植体颈部设计（平齐对接设计、平台转移设计、软组织水平种植体）、种植体植入位置及角度（种植体植入深度、颊舌向位置、近远中位置、颊舌向角度）、修复基台类型及种植体颈部周围软组织的质量等。结合现有文献和笔者的临床实践与思考，为关键区和次关键区的穿龈轮廓设计分类提供临床参考。.
