PURPOSE
The aim of this follow-up study was to report the long-term outcome of all-ceramic cantilever resin-bonded fixed dental prostheses (RBFDPs).
MATERIALS AND METHODS
In 16 patients (mean age of 33.3±17.5years) 22 RBFDPs made from a glass-infiltrated alumina ceramic (In-Ceram) were inserted with a phosphate monomer containing luting agent after air-abrasion of the retainer wings. The abutment preparation included a shallow groove on the cingulum and a small proximal box. The restorations replacing 16 maxillary and 6 mandibular incisors were followed over a mean observation time of 188.7 months.
RESULTS
No restoration debonded. Two RBFDPs fractured and were lost 48 and 214 months after insertion, respectively. The 10-year and 15-year survival rates were both 95.4% and dropped to 81.8% after 18 years.
CONCLUSION
Anterior all-ceramic cantilever RBFDPs exhibited an excellent clinical longevity.
目的
本随访研究的目的是报告全瓷悬臂式树脂粘结固定义齿（RBFDPs）的长期效果。
材料与方法
在16例患者（平均年龄33.3±17.5岁）中，22颗由玻璃渗透氧化铝陶瓷（In-Ceram）制成的RBFDPs在对固位体翼板进行空气喷砂处理后，用含磷酸盐单体的粘结剂进行粘结。基牙预备包括在舌隆突上制备一条浅沟和一个小的邻面箱形洞。对替换16颗上颌切牙和6颗下颌切牙的修复体进行了平均188.7个月的随访观察。
结果
无修复体脱落。两颗RBFDPs分别在粘结后48个月和214个月发生折断并脱落。10年和15年的生存率均为95.4%，18年后降至81.8%。
结论
前牙全瓷悬臂式RBFDPs具有良好的临床长期效果。
