This article reviews the development of esthetic implant abutments and illustrates the use of aluminum oxide implant abutments in two cases.
Two patients were restored with single-tooth implants for the replacement of anterior teeth. One patient received a prefabricated aluminum oxide abutment, which was customized by the dental technician. A second patient received a custom aluminum oxide abutment, which was designed and fabricated using CAD/CAM technology. Both cases were restored with all-ceramic crowns.
Satisfactory functional and esthetic results were achieved in both cases. The CAD/CAM abutment required no further customization in the dental laboratory.
The use of aluminum oxide ceramic abutments improves dental and mucogingival esthetics in single-implant restorations. The use of CAD/CAM technology simplifies the design and customization process. Clinical studies are required to confirm the long-term performance of this type of restoration.
本文回顾了美学种植基台的发展，并举例说明氧化锆种植基台在两个病例中的应用。
两名患者接受单颗牙种植修复前牙。一名患者使用由牙科技师定制的预制氧化锆基台。另一名患者接受了使用CAD/CAM技术设计和制作的定制氧化锆基台。两个病例均采用全瓷冠修复。
两个病例均取得了满意的功能和美学效果。CAD/CAM基台无需在牙科实验室进一步定制。
氧化锆陶瓷基台的使用改善了单颗种植修复的牙齿和牙龈美学效果。CAD/CAM技术的使用简化了设计和定制过程。需要进行临床研究以确认这类修复体的长期性能。
