The oral rehabilitation with fixed restorations supported by the combination of teeth and dental implants has been advocated in some cases.
To assess the clinical outcomes of these prostheses. Fixed restorations supported by the combination of teeth and dental implants.
This retrospective study included all patients treated with combined tooth-implant-supported fixed dental prostheses (FDPs) at one specialist clinic. Abutment/prosthesis failure and technical complications were the outcomes analyzed.
A total of 85 patients with 96 prostheses were included, with a mean follow-up of 10.5 years. Twenty prostheses failed. The estimated cumulative survival rate was 90.7%, 84.8%, 69.9%, and 66.2% at 5, 10, 15, and 20 years, respectively. The failure of tooth and/or implant abutments in key positions affected the survival of the prostheses. There were seven reasons for prostheses failure, with the loss of abutments exerting a significant influence. Bruxism was possibly associated with failures. Prostheses with cantilevers did not show a statistically significant higher failure rate. No group had a general higher prevalence of technical complications in comparison to the other groups.
Although combined tooth-implant-supported FDPs are an alternative treatment option, this study has found that across 20 years of service nearly 35% the prostheses may fail.
在某些情况下，提倡采用牙-种植体联合支持的固定修复体进行口腔修复。
评估这些修复体的临床效果。牙-种植体联合支持的固定修复体。
本回顾性研究纳入了一家专科诊所中所有接受联合牙-种植体支持固定义齿修复（FDP）治疗的患者。分析了基牙/修复体失败和技术并发症这两个结果。
共纳入 85 例患者，共 96 个修复体，平均随访 10.5 年。20 个修复体失败。5、10、15 和 20 年的估计累积存活率分别为 90.7%、84.8%、69.9%和 66.2%。在关键位置的牙和/或种植体基牙的失败会影响修复体的存活率。修复体失败的原因有七个，其中基牙的丧失有显著影响。磨牙症可能与失败有关。有悬臂的修复体没有显示出统计学上更高的失败率。与其他组相比，没有一组的技术并发症普遍更高。
尽管牙-种植体联合支持的 FDP 是一种替代治疗选择，但本研究发现，在 20 年的服务中，近 35%的修复体可能会失败。
