在口腔修复操作实践中,由于塑料的调拌、充填及热处理,任何环节操作不当均可使义齿基板出现气泡,严重影响义齿的外观及质量。为了克服以上缺点,确保义齿的质量,且能缩短热处理时间和便于控制,我们医工结合共同设计制作“液压式义齿热处理器”供临床应用,现介绍如下:1　基本原理 In the practice of oral remediation, due to the mixing, filling and heat treatment of plastics, improper operation of any part can cause bubbles on the substrate of the denture, which will seriously affect the appearance and quality of the denture. In order to overcome the above shortcomings, ensure the quality of dentures, and shorten the heat treatment time and facilitate control, our medical workers jointly design and produce “hydraulic denture heat processor” for clinical applications. Now it is introduced as follows: 1 Basic principles
