The esthetic outcome of implant-supported restorations has become increasingly important, especially for single-tooth implants in the esthetic zone. Because of the morphologic alterations that occur following tooth extraction, augmentation procedures are often necessary before, during, or after implantation to achieve an esthetically pleasing result. This article describes a modified technique for augmenting the soft tissue during stage-two implant surgery. The technique uses a modified roll flap, in combination with a tunneling approach to the adjacent teeth and a coronally positioned palatal sliding flap, to achieve sufficient horizontal dimensions and a scarless and harmonious architecture of the peri-implant soft tissue.
种植体支持修复体的美学效果变得越来越重要，尤其是对于美学区域的单颗牙种植体。由于拔牙后会发生形态改变，因此在种植前、种植期间或种植后通常需要进行增量手术，以获得美观的效果。本文介绍了一种在二期种植手术中增加软组织的改良技术。该技术采用改良的卷瓣，结合向邻牙的隧道式入路和腭侧冠向滑动瓣，以获得足够的水平尺寸和种植体周围软组织无瘢痕且协调的结构。
