Abstract

This prospective clinical study evaluated the survival of indirect, posterior fiber-reinforced composite fixed dental prosthesis (FRC FDP). Between June-1999 and June- 2000, 58 patients received 65 FCR FDPs made of unidirectional E-glass fibers (Vectris) veneered with resin composite (Signum) that were adhesively cemented (Variolink II). The evaluation protocol involved technical (chipping, debonding or fracture of tooth/restoration) and biological failures (caries, endodontic complications). Altogether, 6 technical failures were observed after a mean observation time of 180 months (survival rate: 89.2%, Kaplan-Meier) in the form of fractures (n=2) and partial debondings (n=4). All defective restorations were repaired or recemented. Secondary caries occurred in one patient after 11 years. The 3-unit posterior FRC FDPs showed good clinical survival rate up to 15 years of clinical function. Limited numbers of experienced failures were due to mainly debonding followed by fracture of the veneering composite.g composite.

间接后牙纤维增强复合材料固定义齿的临床存活率：长达 15 年的前瞻性临床随访。

这项前瞻性临床研究评估了间接后牙纤维增强复合材料固定义齿（FRC FDP）的存活率。在 1999 年 6 月至 2000 年 6 月期间，58 名患者接受了 65 个由单向 E 玻璃纤维（Vectris）和树脂复合材料（Signum）贴面制成的 FCR FDP，这些 FDP 采用粘接剂（Variolink II）粘接。评估方案包括技术故障（牙齿/修复体崩裂、脱粘或折断）和生物故障（龋齿、牙髓并发症）。平均观察时间为 180 个月（存活率：89.2%，Kaplan-Meier），共观察到 6 次技术故障，分别为断裂（2 次）和部分脱落（4 次）。所有有缺陷的修复体都得到了修复或接收。一名患者在 11 年后出现二次龋坏。3单位后牙FRC FDP的临床存活率良好，临床功能可长达15年。少数失败案例的主要原因是贴面复合材料的脱粘和断裂。
