Implant-supported restorations in the upper anterior segment need to meet biological, functional, and esthetic requirements to be successful. Bone availability and soft-tissue characteristics in the area of implant placement are crucial for achieving maximum success. This article describes the steps involved in replacing a fractured upper central incisor with an implant-supported crown. Using surgical techniques involving extraction socket preservation/augmentation and connective tissue grafting, ideal positioning of the implant was possible and gingival contours were idealized. With this multiple step treatment, the final restoration met biological and functional requirements and its esthetic results were maximized.
在上颌前牙区，种植体支持的修复体要取得成功，需要满足生物学、功能和美学要求。种植体植入区域的骨量及软组织特性对于实现最大程度的成功至关重要。本文描述了用种植体支持的冠修复上颌中切牙折断的步骤。通过采用拔牙窝保存/增量及结缔组织移植等外科技术，实现了种植体的理想定位，牙龈轮廓也得以理想化。通过这一多步骤治疗，最终修复体满足了生物学和功能要求，并使美学效果最大化。
