树脂复合材料已成为直接后路置换的首选，并越来越受到临床医生和患者的欢迎。同时，文献中的一些临床报告讨论了这些支架的长期耐久性。在这篇综述中，我们检索了牙科文献，寻找1996年至2011年期间发表的至少5年随访期内研究后牙复合体脱位的临床试验。检索结果为34项选定研究。90%的临床研究表明，I类和II类后牙复合矫正的年失败率在1%到3%之间，这取决于几个因素，如牙齿类型和位置、术者、社会经济、人口统计学和行为因素。材料特性对寿命的影响较小。长期失败的主要原因是继发性龋，与个体龋风险有关，和断裂，与衬里的存在或所用材料的强度以及患者因素如磨牙症有关。修复是替代更换的可行方法，它可以显著延长设备的使用寿命。正如文献综述中所观察到的，如果在进行重建时考虑到患者、术者和材料因素，则可以预期后路复合重建的长期生存率。(C)2011年牙科材料学院。由爱思唯尔有限公司出版。保留所有权利。
Resin composites have become the first choice for direct posterior restorations and are increasingly popular among clinicians and patients. Meanwhile, a number of clinical reports in the literature have discussed the durability of these restorations over long periods. In this review, we have searched the dental literature looking for clinical trials investigating posterior composite restorations over periods of at least 5 years of follow-up published between 1996 and 2011. The search resulted in 34 selected studies. 90% of the clinical studies indicated that annual failure rates between 1% and 3% can be achieved with Class I and II posterior composite restorations depending on several factors such as tooth type and location, operator, and socioeconomic, demographic, and behavioral elements. The material properties showed a minor effect on longevity. The main reasons for failure in the long term are secondary caries, related to the individual caries risk, and fracture, related to the presence of a lining or the strength of the material used as well as patient factors such as bruxism. Repair is a viable alternative to replacement, and it can increase significantly the lifetime of restorations. As observed in the literature reviewed, a long survival rate for posterior composite restorations can be expected provided that patient, operator and materials factors are taken into account when the restorations are performed.
