一、按蜡型重量计算法制作活动托牙,在充胶之前必需制作蜡型,根据用蜡量的多少,可以推算出牙托粉的用量。我们将上海齿科材料厂出产的红蜡片,用天平进行称量,经过统计学处理,测出每一片。根据试验计算,每一克蜡型,需用0.91克牙托粉进行充填,不包括牙托水重量,为了保证牙托粉用量足够,并扣除在操作过程中的少量浪费,可按每克蜡型用1克牙托粉计算,换算成体积,一克牙托粉等于1.2ml。雕蜡型所用蜡的重量,可用估计法推算: A.用整块蜡片制作蜡型,最后计算用去的蜡约
First, according to the method of calculating the weight of the wax production activities denture, wax must be made before the filling type, according to the amount of wax used, you can calculate the amount of dental care powder. We will be produced in Shanghai Dental Materials Factory wax tablets, weighed with a balance, after statistical processing, measured each piece. According to the test calculation, each gram of wax, need to use 0.91 grams of dental powder filling, not including the weight of the trays water, in order to ensure adequate dosage of powdered trash, and in addition to a small amount of waste during the operation can be per gram of wax Type with 1 g dentin powder calculation, converted into volume, one gram of dentin powder equal to 1.2ml. Wax wax used in the weight of the wax can be estimated using the estimated: A. Wax production with wax pieces, the final calculation of spent wax about
