目的通过调查临床使用固定修复体的类型和材料,分析上海市口腔固定修复的特点.方法收集上海市三家公立医院的较大规模口腔科门诊和两家大型私立义齿制作所2005年1月-2007年12月的资料,整理固定修复体记录.观察和比较每年制作固定修复体的数量、类型和材料,分析不同类型及材料固定修复体应用比例的变化.结果资料分析显示,2005-2007年,固定修复体总体数量呈现逐年递增趋势,其中金属烤瓷冠所占比例最大.公立医院贵金属全冠的应用数量逐年增加,2005-2006年和2006-2007年的增幅分别为13.85%和30.86%;而普通金属铸造冠的使用率则逐年下降.公立医院和私立义齿制作所计算机辅助制作设计与制作(CAD/CAM)固定修复体(CAD/CAM全冠)和种植体义齿的应用和制作占固定修复体总数的比例均较小,但两者的绝对数量逐年增长趋势明显,其中2006年较2005年分别增长227.78%和53.01%,2007年较2006年分别增长120.34%和27.41%.结论固定修复体仍是目前临床最常用的牙体和牙列缺损的修复方式,其变化主要表现在新技术和优质材料的选用增加.

Objective To collect the information about the types and clinically-used materials for fixed partial dentures, and evaluate the current conditions and characteristics of fixed partial dentures in Shanghai. Methods Three municipal public hospitals and two private commercial dental labs in Shanghai were served as sample units. The data of fixed partial dentures from January 2005 to December 2007 were retrospectively analysed. The number, type and material of dentures of each year were observed, and the proportion of different types and materials of dentures were analysed. Results From 2005 to 2007, the total number of fixed partial dentures gradually increased year by year, and porcelain fused metal crowns accounted for the largest proportion. The application of noble crown in public hospitals increased annually, and the increase rates were 13.85% in 2005 to 2006 and 30.86% in 2006 to 2007, respectively, while the application of casting basic metal full crown decreased annually. Computer-aided design and computer-aided manufacture (CAD/CAM) fixed partial dentures (CAD/CAM crown) and implant dentures occupied a tiny percentage of total fixed partial dentures in public hospitals and privated dental labs, while both had a remarkable increase trend in number between 2005 and 2007 (227.78% and 53.01%, respectively for 2005 to 2006, and 120.34% and 27.41%, respectively for 2006 to 2007). Conclusion Fixed partial dentures are the most common prostheses for tooth defect, and are characterized by the growing application of advanced techniques and high-quality materials.
