CAD/CAM全瓷髓腔固位冠修复根管治疗后磨牙牙体缺损的回顾性研究
Retrospective study of CAD/CAM all-ceramic endocrowns for restoring tooth defect in molars after root canal treatment
摘要
Abstract
Objective:To explore the clinical effects and failure reasons of CAD/CAM all-ceramic endocrowns for molars after root canal treatment.Methods:A retrospective study was conducted on follow-up 276 teeth(112 maxillary molars and 164 mandibular molars)treated in author's hospital from February 2018 to February 2021.The clinical outcomes of the endocrowns were evaluated using the World Dental Federation(FDI)criteria.The success rate,survival rate,and failure rate of endocrowns over 5～8 years(mean 6.5 years)were studied and analyzed,along with patient satisfaction and failure causes.Results:The success rate of endocrowns was 89.49%,the survival rate was 93.12%,and the failure rate was 10.51%.Pa-tient satisfaction rates for the shape,color,and comfort of endocrowns reached 98.19%,98.55%,and 98.55%,respectively.No statistically significant difference was observed between the maxillary and mandibular molar groups(P>0.05).Conclu-sion:CAD/CAM all-ceramic endocrowns demonstrate favorable clinical outcomes and high patient satisfaction for molars after root canal treatment.However,strict adherence to indications and standardized clinical procedures are essential to reduce fail-ure risks.关键词
