Loss of anterior maxillary teeth always results in bone resorption and loss of interdental papillae, making a single tooth replacement by an implant very difficult. When infections have been present and previous surgery at the apex of the root has taken place, bone destruction is substantial, increasing the resorption defect and aesthetic and prosthetic problems. The learning objective of this article is to describe the steps necessary for implant surgery and prosthetics. It includes bone regeneration procedures, implant placement, second stage surgery, reconstruction of interdental papillae, abutment selection, and the various prosthetic procedures. Several cases are used to illustrate.
上颌前牙缺失总会导致骨吸收和牙间乳头丧失，使得通过种植体进行单颗牙齿修复非常困难。当存在感染且先前在牙根根尖处进行过手术时，骨破坏会很严重，增加吸收缺损以及美学和修复问题。本文的学习目标是描述种植手术和修复所需的步骤。它包括骨再生程序、种植体植入、二期手术、牙间乳头重建、基台选择以及各种修复程序。文中用几个病例进行说明。
