This article describes treatment provided to replace 2 maxillary central incisors with implant-supported restorations. The site of a missing maxillary central incisor was treated utilizing a bone expansion technique to augment the labial hard and soft-tissue profiles at the time of implant placement. The adjacent central incisor tooth, although destined to be extracted, was retained to serve as an abutment for a fixed provisional restoration until the first implant was deemed to have successfully integrated. At the appointment to uncover this implant, the fractured tooth was extracted and an implant was immediately placed into the socket. The first implant was then used to support the provisional restoration during the healing phase of the second implant. The techniques utilized resulted in optimum soft-tissue contours, allowed the patient to have a comfortable and esthetic provisional restoration, and minimized the number of surgical procedures.
本文描述了采用种植体支持修复体替换两颗上颌中切牙的治疗过程。在上颌中切牙缺失部位进行治疗时，采用骨扩张技术在种植体植入时增加唇侧软硬组织轮廓。相邻的中切牙尽管最终要拔除，但在第一颗种植体被认为成功整合之前，保留该牙作为固定临时修复体的基牙。在揭开这颗种植体的复诊时，拔除折断的牙齿，并立即在牙槽窝内植入一颗种植体。然后在第二颗种植体的愈合阶段，用第一颗种植体支持临时修复体。所采用的技术产生了最佳的软组织轮廓，使患者拥有舒适且美观的临时修复体，并将外科手术的次数减至最少。
