Clinical success of an endosseous implant to replace a single tooth is not only defined by its survival. Esthetic parameters have become integral aspects in defining success and failure. All-ceramic abutments have started to play a major role in achieving an esthetically successful result. The material itself, however, is not the exclusive determinant for esthetic success. It is the appropriate design and proper handling of the material and the abutment that enables the clinician to achieve esthetic outcomes that were not possible with traditional metal alloys. This article explores the rationale for using zirconia for prosthetic implant components, explains specific material properties, and discusses strategies and guidelines for the design and successful clinical implementation of CAD/CAM-fabricated zirconia implant abutments.
种植体替代单颗牙齿的临床成功不仅取决于其存留情况。美学参数已成为定义成败的重要因素。全瓷基台在实现美学成功方面已开始发挥重要作用。然而，材料本身并非美学成功的唯一决定因素。材料和基台的恰当设计及正确处理，使临床医生能够实现传统金属合金无法达成的美学效果。本文探讨了使用氧化锆制作种植修复组件的基本原理，解释了其具体材料特性，并讨论了CAD/CAM制作的氧化锆种植体基台的设计及成功临床应用的策略和指导原则。
