摘　　要：目的探讨不同种类固定修复体的市场需求和需求变化。方法收集四川华西义齿修复制作中心2009—2011年生产的95 789件固定修复体为研究对象,统计产量构成比、绘制产量趋势图,分析固定修复体的市场需求及变化,采用季节指数分析固定修复体的产量规律。结果金属烤瓷修复体的构成比达到90%以上,钯银合金烤瓷修复体是主要的修复体选择类别,镍铬合金烤瓷修复体产量逐年降低,钴铬合金烤瓷修复体、种植体固定修复体、全瓷修复体产量保持稳定增长,金铂合金烤瓷修复体稳定在一定水平呈上下波动;季节指数的高峰为7月,指数达到1.155 56,低谷为2月,指数达到0.840 79,季节指数最高和最低月份相差0.314 77。结论金属烤瓷修复体占市场需求的主导地位,镍铬合金烤瓷修复体的产量逐年降低并逐渐被钴铬合金烤瓷修复体代替,固定修复体的产量存在季节波动,应优化资源配置并积极推广新技术。Objective To investigate the market demand and diversification of different types of fixed prosthe- ses. Methods 95 789 representative samples collected in dental laboratory technology center during 2009 to 2011 were statistically analyzed in terms of proportions and trends. Change situation of production was analyzed by seasonal index. Results The proportions of porcelain fused to metal prosthesis were higher than 90%; porce- lain fused to palladium-silver prosthesis were the main type; the production of porcelain fused to nickel-chromium alloy prosthesis cut down year by year; porcelain fused to cobalt-chromium alloy prosthesis, non-ceramic prosthe- sis and implant prosthesis maintained in steady growth; porcelain fused to gold-platinum alloy prosthesis stabilized at a certain level; the highest month of season index was July, which index reached 1.155 56, while season index of February was the lowest, which index reached 0.840 79, the highest month of season index differed 0.314 77 from the lowest one. Conclusion Porcelain fused to metal prosthesis dominated the market, porcelain fused to nickel-chromium alloy prosthesis was replaced by porcelain fused to cobalt-chromium alloy prosthesis gradually; the production of fixed prostheses had seasonal fluctuations, thus the resource allocation and technology promotion should be improved in future.
