一概述:我国瓷牙的研究和生产从1947年起步,那时所用设备比较简陋,工艺尚停留在瓷牙发展的初级阶段,使用低温熔瓷制作瓷牙,其熔点较低,在870～1065℃,生产的是第一代中孔瓷牙。1957年研究生产出第二代瓷牙,即横穿瓷牙。1960年,研究使用中温熔瓷制作瓷牙,其熔点在1092～1259℃,第三代瓷牙,即中温横串瓷牙诞生。1964年,又研究了第四代高温真空烧成的瓷牙—合金钉瓷牙。这样在瓷牙生产制造工艺上,开始使用熔点在1315～1370℃的高温熔瓷,使瓷牙的工艺日趋完善,瓷牙的内在质量达到了最佳状态。此后,在使用高温熔瓷制作瓷牙的基础上,又陆续研制生产出黄金钉瓷牙,JZ-81型白合金钉瓷牙等等高质量的瓷牙品质(见附图)。
An overview: China's porcelain teeth research and production started from 1947, when the equipment is relatively simple, the process still stays in the primary stage of the development of porcelain teeth, the use of low-temperature porcelain to make porcelain teeth, the lower the melting point of 870 ~ 1065 ℃, the production is the first generation of porcelain teeth. 1957 study produced the second generation of porcelain teeth, that crosses porcelain teeth. In 1960, the study of the use of porcelain teeth in the production of intermediate temperature melting, the melting point of 1092 ~ 1259 ℃, the third generation porcelain teeth, that is, the birth of the cross-type porcelain teeth. In 1964, another study of the fourth generation of high temperature vacuum porcelain teeth - alloy porcelain teeth. This porcelain tooth manufacturing process, began to use the melting point of 1315 ~ 1370 ℃ high temperature melting porcelain, Porcelain teeth process is perfect, the inherent quality of porcelain teeth to achieve the best condition. Since then, the use of high-temperature porcelain porcelain teeth on the basis of the successful development of another production of gold nail porcelain teeth, JZ-81-type white ceramic nail porcelain teeth and other high-quality porcelain teeth quality (see photo).
