Restoring edentulous areas with fixed prostheses can be challenging, especially when key abutment teeth are missing and implant placement is not an option. Sometimes, clinicians are faced with situations where teeth have to be connected with implants even though long-term prognosis of those connections may be questionable. This clinical report presents a connection of 2 implants with 1 tooth in the esthetic zone with a nonrigid connection. Two zirconia custom abutments and 1 zirconia coping definitively cemented on the tooth were used. A zirconia superstructure, veneered with porcelain, was cemented with provisional cement on the abutments and the coping.
用固定义齿修复无牙颌区域可能具有挑战性，特别是当关键基牙缺失且不能进行种植时。有时，临床医生会遇到需要将牙齿与种植体连接的情况，尽管这些连接的长期预后可能存在疑问。本临床报告介绍了使用非刚性连接，在美学区域将 2 个种植体与 1 个牙齿连接。使用了 2 个氧化锆定制基台和 1 个氧化锆全瓷冠，最终粘接到牙齿上。用临时粘固剂将氧化锆桥架，并用瓷贴面覆盖，粘接到基台上和全瓷冠上。
