一般来说，残疾患者（例如脑瘫患者）的龋齿和其他口腔和牙齿问题的患病率会增加。在初级牙科诊所为脑瘫和智力障碍等疾病的患者提供适当的牙科治疗具有挑战性。本研究的目的是评估脑瘫患者固定假体的寿命并探讨相关预后因素。 36 名脑瘫患者的记录用于收集和分析数据。本研究最终纳入了总共 155 个由金属合金制成的假肢。计算年故障率；通过多变量 Cox 回归分析和引入随机效应的脆弱模型来评估与假体失败相关的患者和牙齿相关变量。 10年假体存活率为62%，20年存活率为36%。就修复体相关变量而言，修复体类型有显着影响，固定局部义齿的风险比是单牙冠的2.32倍。就患者相关变量而言，癫痫的存在对生存有显着影响，合并癫痫的风险比是未合并癫痫患者的3.76倍。我们的研究结果表明，在合并癫痫的情况下，脑瘫患者植入的固定假肢的存活率可能特别低。仔细考虑假体的类型和/或设计也可能很重要，以确保更好的预后。
In general, the prevalence of caries and other oral and dental issues is increased in patients with disabilities, such as those with cerebral palsy. Providing appropriate dental treatment at a primary dental clinic for patients with cerebral palsy and intellectual disability, among other conditions, is challenging. The objective of this study was to evaluate the longevity and investigate the related prognostic factors of fixed prostheses in patients with cerebral palsy. The records of 36 cerebral palsy patients were used for collecting and analyzing data. A total of 155 prostheses made from metal alloys were finally included in this study. Annual failure rates were calculated; patient‐ and tooth‐related variables associated with prosthesis failure were assessed by a multivariate Cox‐regression analysis and frailty models to introduce random effects. The 10‐year prosthesis survival rate was 62% and the 20‐year survival rate was 36%. In terms of prosthesis‐related variables, the type of prosthesis had a significant effect, and the hazard ratio of fixed partial dentures was 2.32 times that of single‐unit crowns. In terms of patient‐related variables, the presence of epilepsy had a significant effect on survival, and the hazard ratio for comorbid epilepsy was 3.76 times that for those without comorbid epilepsy. Our findings suggested that fixed prostheses placed in patients with cerebral palsy might have a particularly low survival rate in cases with comorbid epilepsy. It might also be important to consider the type and/or design of the prosthesis carefully to ensure a better prognosis.
