This case report describes the clinical and technical placement procedures for single tooth implant-supported restorations at the time of second-stage surgery. After an implant is placed, its position in relationship to the adjoining teeth can be precisely recorded, using an impression coping and a prefabricated individual resin tray. The tray and the impression coping are joined with self-curing resin and then remounted on the master cast to place an implant analog. The modified master cast is used to fabricate the definitive restoration. Following second-stage surgery, an all-ceramic single crown is placed. The periimplant tissues are molded into position by the definitive restoration, and the healing of the periimplant tissues is controlled entirely by the anatomy of the prefabricated definitive restoration. The learning objective of this article is to familiarize clinicians with placement of implant-supported restorations at the time of second-stage surgery. The method is simple and efficient, and it can also be used with one-phase implant system restorations.
本病例报告描述了二期手术时单颗牙种植体支持修复体的临床及技术放置程序。种植体植入后，使用印模帽和预制的个性化树脂托盘，可以精确记录其与相邻牙齿的位置关系。将托盘和印模帽用自凝树脂连接，然后重新安装在主模型上以放置种植体代型。修改后的主模型用于制作最终修复体。二期手术后，放置全瓷单冠。最终修复体将种植体周围组织塑形就位，种植体周围组织的愈合完全由预制最终修复体的解剖结构控制。本文的学习目标是使临床医生熟悉二期手术时种植体支持修复体的放置。该方法简单有效，也可用于一期种植系统修复体。
