Clinical Evaluation of Simplified Biofunctional Prosthetic Denture in Edentulous Patients
-
摘要:
目的 评价使用简化生物功能性义齿（simplified biofunctional prosthetic denture，SBPD）修复牙列缺失的疗效及患者满意度。 方法 收集深圳大学总医院牙列缺失拟行全口义齿修复的患者26例，随机分为两组，分别采用传统全口义齿（conventional complete denture，CCD）修复方法（n = 13）和SBPD修复方法（n = 13）制作全口义齿，于戴牙后即刻、戴牙后1个月和戴牙后3个月填写义齿满意度视觉模拟评分量表（Visual analogue scale，VAS）进行满意度调查。 结果 戴牙后即刻、戴牙后1个月和戴牙后3个月，在咀嚼功能、舒适性及固位功能方面应用SBPD修复方法制作的全口义齿满意度显著高于CCD方法制作的全口义齿（P < 0.05）。 结论 应用SBPD修复方法制作全口义齿能够取得比较好的临床效果，值得进一步实践和推广。 -

Abstract:Objective To evaluate the efficacy and satisfaction of the edentulous patients with the simplified biofunctional prosthetic denture （SBPD）. Methods 26 patients with complete denture restoration were randomly divided into two groups: conventional complete denture （CCD） group （n = 13） andSBPD group （n = 13）. The satisfaction degree was investigated by filling in the visual analoguescale （VAS） at baseline, 1 month and 3 months following the denture delivery. Results In terms of masticatory function, comfort and retention, the VAS score on SBPD group was higher than that of CCD group, （P < 0.05）. Conclusion The SBPD method has the good precision and it is worthy of clinical promotion. -
