摘　　要：目的观察应用可摘局部义齿进行咬合重建并结合复合树脂贴面恢复老年患者牙列缺损的临床效果,并探讨其临床操作特点及适应证。方法选择2002年3月-2003年5月肯氏1类牙列缺损的门诊患者16例,采用可摘局部义齿(RPD)修复并恢复垂直距离,进行咬合重建修复,在此基础上采用光固化复合树脂进行前牙区贴面修复,以恢复前牙区美观、高度并重建切导,部分病例同时应用复合树脂进行了松牙固定。于修复完成后3个月、2年、4年进行随访,树脂修复采用USPHS标准进行评价,RPD则通过问卷调查结合临床检查进行评价。结果临床观察4年,复合树脂修复效果可靠,易于修理调改,调简单方便,并能最大限度保存牙体组织;修复体经济、美观,4年树脂贴面的保存率为85.7%,基本能够满足临床的美观及功能要求;与可摘局部义齿配合使用,克服了后者外观欠佳的缺点。结论应用复合树脂结合可摘局部义齿进行咬合重建具有创伤小、经济、美观、有利于牙体组织保存的优点,易被老年牙列缺损患者所接受,值得进行进一步临床研究。Objective To evaluate the clinical effect of removable partial denture combined with composite resin veneer on occlusal reconstruction for aged patients with dentition defects, and discuss the critical steps of operation. Methods From Mar. 2002 to May 2003, 16 outpatients with Kennedy 1 type dentition defects with severe anterior attrition were selected. The distal extension removable partial denture （RPD） was used to reestablish the occlusal vertical dimension. The anterior teeth were bonded with the light-cured composite resin based on removable partial denture. The therapeutic effects for all the patients were assessed at 3-month, 2 year and ＆year follow-up after treatment. Composite resin restorations were evaluated with modified USPHS criteria, and removable partial denture were assessed by routine examination and subjective questionnaire. Results After 4 years of observation, all prosthesis remained in good condition. The mastieatory ability was increased than ever before and the patients were satisfactory with the esthetic appearance of dentures. The remaining rate of lighvcured composite resin was 85.7% 4 years after reconstruction, fulfilling the requirements of esthetics and function. Meanwhile, the dental structure could be preserved and the unsatisfactory appearance of removable partial denture was improved by light-cured composite resin. Conclusions The dentition defects of aged people may be effectively restored by combined application of removable partial denture and composite resin veneer. This treatment has many advantagcs, including less trauma, economy and satisfactory in esthetics, and be- sides, it may better preserve the dental structure. This treatment is well accepted by aged patients, so it is worthy to do further clinical study.
