PURPOSE
This article reviews the development of esthetic implant abutments and illustrates the use of aluminum oxide implant abutments in two cases.
MATERIALS AND METHODS
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.
RESULTS
Satisfactory functional and esthetic results were achieved in both cases. The CAD/CAM abutment required no further customization in the dental laboratory.
CONCLUSION
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.
目的
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。
材料与方法
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。
结果
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。
结论
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。
