This study evaluated the clinical outcome of all-ceramic resin-bonded fixed partial dentures (RBFPDs) with a cantilevered single-retainer design.
Thirty anterior zirconia ceramic RBFPDs were inserted using either a phosphate monomer containing resin (Panavia 21 TC; N=16) or an adhesive bonding system with a phosphoric acid acrylate primer (Multilink-Automix with Metal/Zirconia primer; N=14).
During a mean observation time of 41.7 months one debonding occurred in each group. Both RBFPDs could be rebonded successfully resulting in a three-year survival rate of 100%.
Independent of the bonding system cantilevered zirconia ceramic RBFPDs showed promising results during the first three years.
Single-retainer zirconia ceramic RBFPD present an alternative treatment option offering good aesthetics, a minimal invasive preparation, a high biocompatibility and can even be used to treat juvenile patients who do not yet come into consideration for implant placement. No significant influence of the bonding system used was detected so far.
本研究评估了具有悬臂单固位体设计的全瓷树脂粘结固定局部义齿（RBFPD）的临床效果。
使用含磷酸盐单体的树脂（Panavia 21 TC；N=16）或具有磷酸丙烯酸酯底漆的粘结系统（Multilink-Automix 配金属/氧化锆底漆；N=14）插入 30 个前牙氧化锆全瓷 RBFPD。
在平均观察时间 41.7 个月期间，每组各发生 1 次脱粘。两个 RBFPD 都可以成功重新粘结，三年生存率为 100%。
无论粘结系统如何，悬臂氧化锆陶瓷 RBFPD 在头三年都显示出良好的效果。
单固位体氧化锆陶瓷 RBFPD 提供了一种替代治疗方案，具有良好的美学效果、微创预备、高度的生物相容性，甚至可用于治疗青少年患者，这些患者尚未考虑进行种植体植入。迄今为止，尚未检测到粘结系统使用的明显影响。
