摘要

目的:关于双牙冠保留可移动义齿(dcrdp)性能的临床数据,特别是大学以外的研究,是很少的。这项回顾性临床研究的目的是评估dcrdp的生存率和无并发症概率,并确定牙科实践环境中失败和并发症的危险因素。材料与方法:对174例患者(56.9%为女性)的匿名实践资料进行评估,共植入213个dcRDP(平均每个dcRDP 3.3个基牙),随访11年(平均观察时间3.9年)。在假体和基台水平上计算生存概率和并发症发生率,并使用Kaplan-Meier方法进行可视化。采用Cox回归分析计算影响失败和并发症的因素(R Ver. 7;alpha结果:在我们的观察期间,39例(18%)dcrdp失败。2年后的平均总生存率(95% CI)为94%(90-97%),5年后的平均总生存率为86%(80-92%)。结论:在牙科实践中,双冠保留假体具有可接受的中期生存率和常见的技术和生物学并发症,通常易于管理。然而,修复体的性能取决于基牙/种植体的质量和数量。在本回顾性分析的局限性内,我们在牙科诊所观察到的结果与在大学研究中发现的结果相当,尽管略差。临床相关性:评估dcrdp在牙科实践中的临床表现对于评估耐久性和并发症模式,以权衡治疗决策非常重要。

Mid-term survival and complications of double-crown-retained removable dental prostheses placed in the dental practice - a retrospective study.

Objectives: Clinical data on the performance of double-crown-retained removable dental prostheses (dcRDPs), especially beyond university studies, are rare. The objective of this retrospective clinical study was to evaluate the survival and complication-freeness probabilities of dcRDPs and to identify risk factors for failure and complications in a dental practice setting.

Materials and methods: Anonymized practice data of 174 patients (56.9% female) fitted with a total of 213 dcRDPs (mean of 3.3 abutment teeth per dcRDP) were evaluated up to 11 years after prothesis placement (mean observation time of 3.9 years). Probabilities of survival and complication freeness were calculated on the prosthesis- and abutment level and visualized using the Kaplan-Meier method. Factors influencing failure and complications were computed using Cox regression analyses (R Ver. 7; alpha < 0.05).

Results: During our observation period, 39 (18%) of the dcRDPs failed. The mean (95% CI) overall survival was 94% (90-97%) after 2 years and 86% (80-92%) after 5 years. DcRDP survival correlated with lower patient age and more abutment teeth (P < 0.05), while other analyzed factors did not. The probability of absence of prosthesis-related complications was 92% after 2 years and 80% after 5 years. The probability of no technical complications of abutments (teeth/implants) was 85% after 2 years and 78% after 5 years, and the probability of no biological complications was 87% after 2 years and 72% after 5 years. In total, 141 dcRDPs (66.2%) faced at least one complication during the observation period.

Conclusions: Double-crown-retained prostheses fitted in a dental practice had acceptable mid-term survival rates and common technical and biological complications that were frequently easily manageable. However, prosthesis performance depended on the quality and number of abutment teeth/implants. Within the limitations of this retrospective analysis, the outcomes we observed in a dental practice are comparable to, albeit slightly worse than, those found in university studies.

Clinical relevance: Evaluation of the clinical performance of dcRDPs fitted in a dental practice is important to estimate durability and complication patterns in order to weigh treatment decisions.
