The aim of this study was to evaluate the clinical performance (retention rate) of fiber-reinforced composite fixed partial dentures (FPDs). Polyethylene fiber (Ribbond) was used combined with restorative composite during FPDs fabrication. FPDs were placed in thirteen patients in a private clinic. Nineteen FPDs were evaluated. The prosthetic space was filled with only one pontic using extracted teeth (2 cases), acrylic resin teeth (11 cases), or with composite resin (6 cases), combined with Polyethylene fiber. The clinical criterion used was based on retention rate of FPDs. If FPDs were in function in the mouth at the time of examination without previous repair they were classified as Complete Survival (CS) restorations. A classification of Survival with Rebonding (SR) was assigned in the event of an adhesive failure, but after rebonding the FPD still remained under evaluation. Treatment was classified as a Failure (F) if the FPD restoration was lost. The time of evaluation was 41.15 months (+/-15.13). The FPDs evaluated were retained (CS=94.75%), and no failure was found except for in one situation which required rebonding (SR=5.25%). According to the survival estimation method of Kaplan-Meyer the mean survival time was 42.3 months. At the time of evaluation investigated, polyethylene-reinforced FPDs showed a favorable retention rate in preliminary data.
本研究的目的是评估纤维增强复合固定局部义齿（FPDs）的临床性能（固位率）。在制作FPDs期间，将聚乙烯纤维（Ribbond）与修复性复合材料联合使用。在一家私人诊所对13例患者置入了FPDs。共评估了19个FPDs。修复间隙仅用一颗桥体进行填充，桥体使用的是拔除的牙齿（2例）、丙烯酸树脂牙（11例）或复合树脂（6例），并结合聚乙烯纤维。所采用的临床标准基于FPDs的固位率。如果在检查时FPDs在口腔中正常发挥功能且之前未进行过修复，则将其分类为完全存活（CS）修复体。如果发生粘结失败，但在重新粘结后FPDs仍在评估范围内，则分类为带重新粘结的存活（SR）。如果FPD修复体丢失，则将治疗分类为失败（F）。评估时间为41.15个月（±15.13）。所评估的FPDs均得以保留（CS = 94.75%），除了一种需要重新粘结的情况（SR = 5.25%）外，未发现失败病例。根据Kaplan - Meyer生存估计方法，平均生存时间为42.3个月。在调查评估时，聚乙烯增强的FPDs在初步数据中显示出良好的固位率。
