海口地区不同种类义齿修复体需求度探讨

目的：对不同义齿修复体的临床应用情况进行分析，为口腔材料学的发展提供临床数据。方法对2013年1月至2014年3月期间来我院进行口腔修复的1295例患者的1609件修复体进行修复体种类和材质等方面的调查。结果在修复体类型方面，采用较多的修复类型为全冠(54.0%)、桩核冠(22.1%)及局部可摘(16.6%)；在修复体材质上，不论是活动类还是固定类修复体都是钴铬合金所占比例最高。结论随着相关科学及材料的发展，口腔修复体的种类逐渐增多，不同种类的修复体有各自不同的理化特性以及各自的临床需求，修复科医生要对修复材料的生物性能、费用情况等做到全面的了解，帮助患者选择最为适宜的修复体材料。

Discussion on the needs of different types of denture in Haikou area

Objective To analyze the clinical applications of different types of denture, and to provide clini-cal data for the development of the science of oral materials. Methods A total of 1 609 cases of dental prosthesis from 1 295 patients undergoing tooth restoration in our hospital from January 2013 to March 2014 were investigated in the prosthesis types and materials. Results In the type of prosthesis, the full crown (54.0%), post core crown (22.1%) and partial removable denture (16.6%) were used often. In the prosthesis material, the proportion of cobalt-chromium al-loy was the highest for both removable and fixed types. Conclusion With the development of related science and mate-rials, the types of dental prosthesis are gradually increased, and different prosthesis have distinct physical and chemical characteristics and specified clinical needs. The doctors' comprehensive understanding on the biological properties of the prosthesis materials and the cost would help the patient choose the most suitable denture.
