Achieving functional and aesthetic implant-supported restorations in the partially edentulous patient can be particularly challenging when the implant sites are in the anterior region and not in harmony with the adjacent dentition. The learning objective of this article is to focus on presurgical evaluation of anterior implant sites and systematic development of related therapeutic modalities. Utilization of guided bone regeneration and connective tissue grafting predictably facilitates implant positioning that is compatible with required aesthetic restoration and soft tissue contours. Other aspects, such as abutment protection caps with variable emergence profiles, provisional restorations for the development of optimal periimplant soft tissue contours, and fabrication guidelines for different types of prosthetic restorations, are also discussed.
对于部分牙列缺损患者，当种植部位位于前牙区且与相邻牙列不协调时，实现功能和美观的种植体支持修复可能会特别具有挑战性。本文的学习目标是专注于前牙种植部位的术前评估以及相关治疗方式的系统开发。可预测地利用引导骨再生和结缔组织移植有助于实现与所需美学修复和软组织轮廓相兼容的种植体定位。还讨论了其他方面，例如具有可变龈缘轮廓的基台保护帽、用于形成最佳种植体周围软组织轮廓的临时修复体以及不同类型修复体的制作指南。
