当前,常用自凝塑胶制作丙烯酸酯塑胶义齿,其主要优点与热凝塑胶相比是花时间少。本研究目的为通过戴自凝及热凝塑胶总义齿的四年追踪,比较两种材料某些生物学及机械方面的性质。材料及方法:任意选择60名病人,30名作自凝塑胶总义齿,30名作热凝塑胶总义齿。在同一实验室内用相同的步骤及方法取印 At present, commonly used self-curing plastic acrylic plastic denture, the main advantages compared with the thermal plastic is to spend less time. The purpose of this study was to compare some of the biological and mechanical properties of two materials through a four-year follow-up of self-cloting and thermocoagulation total dentures. MATERIALS AND METHODS: Sixty patients were randomly selected, 30 were self-coagulating plastic total dentures, and 30 were thermal plastic total dentures. In the same laboratory with the same steps and methods for printing
