Abstract

Well-placed dental implants are a prerequisite of functional and esthetically successful dental implant-supported crowns. The presence of soft tissue is essential for excellent esthetics because the dental implant or titanium abutment may become visible if the soft-tissue contour is not acceptable. This clinical report describes the use of a custom ceramic implant abutment designed with computer-aided design and computer-aided manufacturing (CAD/CAM) technology by milling a zirconia framework that was cemented extraorally to a prefabricated titanium abutment with a reduced diameter. This ceramic abutment has the strength and precise fit of a titanium interface and also the esthetic advantages of shaded custom-milled zirconia, with no visible metal.

摘要

位置合适的牙种植体是牙种植体支持的冠在功能和美学上取得成功的前提条件。软组织的存在对于出色的美学效果至关重要，因为如果软组织轮廓不理想，牙种植体或钛基台可能会暴露可见。本临床报告描述了一种定制陶瓷种植体基台的应用，该基台采用计算机辅助设计和计算机辅助制造（CAD/CAM）技术设计，通过铣削氧化锆框架制成，该框架在口外粘结到直径减小的预制钛基台上。这种陶瓷基台具有钛界面的强度和精确贴合度，同时还具有定制铣削氧化锆的美学优势，无可见金属。
