摘要
目的探讨RPI卡环和三臂卡环固位体可摘局部义齿修复远中游离端缺失的效果。方法回顾性分析2015年5月~2016年5月北京瑞泰口腔医院82例(义齿160件)戴用远中游离端铸造支架式可摘局部义齿的患者,按照卡环固位体的不同将其分为RPI卡环组(41例,义齿81件)和三臂卡环组(41例,义齿79件)。RPI卡环组行RPI卡环固位体铸造支架式可摘局部义齿修复,三臂卡环组行三臂卡环固位体铸造支架式可摘局部义齿修复。自制调查问卷,比较两组患者口腔检查、主观评价情况。结果RPI卡环组患者可摘局部义齿修复后基牙松动、卡环固位、义齿总体恢复的效果明显优于三臂卡环组,差异有统计学意义(P<0.05);但两组基牙密合情况比较,差异无统计学意义(P>0.05)。RPI卡环组患者主观评价效果明显优于三臂卡环组,差异有统计学意义(P<0.01)。结论RPI卡环修复远中游离端缺失,可改善基牙松动状态,整体恢复良好,值得在临床上推广应用。同时要加强口腔卫生,加强修复体总体设计,定期复查。
Objective To compare the effect of removable partial denture with RPI clasp and three-arm clasp in repairing distal-extension free end deletion.Methods From May 2015 to May 2016,82 patients(160 dentures)wearing distal-extension free end cast bracket removable partial denture in Beijing Rytime Stomatological Hospital were retrospectively analyzed.They were divided into RPI clasp group(41 cases,81 dentures)and three-arm clasp group(41 cases,79 dentures)according to the different retainers of clasp.RPI clasp group was repaired with RPI clasp retainer casting bracket removable partial denture,and three-arm clasp group was repaired with three-arm clasp retainer casting bracket removable partial denture.Self-made questionnaires were used to compare the oral examination and subjective evaluation of the two groups.Results The effect of abutment loosening,clasp retention and overall restoration after removable partial dentures in the RPI clasp group were better than those in the three-arm clasp group with statistical significances(P<0.05),but there was no significant difference in abutment occlusion between the two groups(P>0.05).Subjective evaluation in the RPI clasp group was better than that in the three-arm clasp group,and the difference was statistically significant(P<0.01).Conclusion RPI clasp repair with distal-extension free end deletion can improve the loose state of the abutment teeth and the overall recovery is good,which is worthy of clinical application.At the same time,oral hygiene should be strengthened,the overall design of prostheses should be strengthened,and regular reviews should be conducted.
