个性化全瓷基台在前牙区种植美容修复中的应用

目的：研究全瓷基台在前牙区软硬组织不足患者中种植修复的关学效果。方法：选取临床上因种植区域软硬纽织不足存在金属基台颜色外露、角度偏差大、龈乳头低平缺损，成品基台又无法达到美学修复效果的上前牙种植修复患者17例，利用计算机辅助制造／计算机辅助制造（CAD／CAM）技术制作个性化全瓷基台并完成铸造全瓷外冠，改善牙颈部透黑现象。结果：17例患者共制作了21件修复体，均改善了牙颈部透黑现象，达到较为理想的美学效果，跟踪观察期（6、12个月）内牙龈健康，未见软硬组织退缩与种植体周围炎发生。结论：个性化全瓷基台可有效改善前牙区种植后的美容修复效果。

The application of personalized all-ceramic abutments in anterior implant aesthetic restorations

Objective To evaluate the esthetic effects of all-ceramic abutment in hard tissues-deficient of anterior teeth regions. Methods 17 anterior implanted patients were selected in this study,they didn＇t have efficient hard tissue and the metal abutments were exposed easily, the angle deviation was high and gingival papilla was low and flat and the finished abutment cannot achieve aesthetic prosthetic effects.CAD/CAM technique was used to make individual all-ceramic abutments and cast ceramic crows to diminish ＂through the black＂ phenomenon of the teeth neck. Results 21 prosthesis were made for the 17 patients,the ＂through the black＂ phenomenon were diminished greatly and fine aesthetic effects were achieved.The gingival was healthy and no peri implantitis,soft or hard tissue defect were found. Conclusion The individual all-ceramic abutments can improve aesthetic prosthesis effects of anterior restorations significantly.
