老年人牙缺失临床修复治疗的分析

目的了解老年修复患者的口腔情况及修复特点。方法对1 166例60岁以上老年人牙缺失患者作修复治疗，分析缺牙及修复情况。结果1 166例患者平均缺牙10.25颗。牙缺失数上领>下领，磨牙>双尖牙>切牙>尖牙。1 166例患者中1 120例作可摘义齿修复，其中游离端缺失约占58%0 46例作固定义齿修复。结论老年修复患者具有缺牙数目多，游离端缺失多，余牙磨耗严重，食物嵌塞多，余留牙松动及残根多等特点;修复以可摘义齿为主，可适当行固定义齿修复。修复治疗时尽量发挥尖牙、已治疗的残根及健康第三磨牙的作用。

The Survey of Prosthetic Treatment in the Elderly

Objective To acquire teeth and prosthetic conditions of the elderly. Methods 1 166 patients of over 60 years old had been given prosthetic treatment, and the teeth conditions were analyzed. Results The average number of missing teeth was 10.25. The maxillary missing teeth were more than mandibular ones. The rate of missing teeth were as follows: maxillary teeth > mandibular teeth;molars > bicuspids > incisors > cuspid. 1120 cases were treated with removable dentures. 59% of the removable partial dentures had free-end saddles. 46 cases were treated with fixed bridges. Conclusion The characteristics of prosthetic patients in the elderly were as follows: a large number of missing teeth and free-end missing teeth, attrition of resident teeth, food impaction, existing-residual root and loosen teeth. Removable denture was the main method of the prosthetic therapy for the elderly patients. Fixed bridge was used when the patient condition was good. The cuspid, treated residual root and the third molar should be used for the retention and support of the prosthesis
