本研究目的:(1比较五种常用来制作全瓷边缘的瓷的弯曲强度,(2)决定三种表面处理对瓷弯曲强度的影响。方法和材料五种用以试验的瓷是(1)用塑型液作为粘合剂的vita 体瓷,(2)用塑型液作为粘合剂的vita 肩台瓷,(3)用硅溶胶液作为粘合剂的vita肩台瓷,(4)用蒸馏水作为粘合剂的Crystar 肩台瓷,(5)用硅溶胶液作为粘合剂的Crystar 肩台瓷,用塑型液做为粘合剂的体瓷作为对照。每个系统分别制作30个样本。用来实验的覆以金属片的瓷样本含有以下三层:(1)0.3mm 厚的金钯合金基底,(2)0.3mm 厚的不透明瓷层;(3)用来实验的瓷混合物。每个含有30个样本的系统,再以每10个为1个亚组分为3组。亚组接受下列不同的表面处理:(1)自身上釉,(2)表面上釉,(3)自身上釉后抛光。结果记录下每个样本使瓷断裂的最大力量,将这些原始资料输入计算机作统计学分析。得知用蒸馏水作
The purpose of this study: (1) To compare the bending strength of five porcelain used to make all-ceramic edge, (2) To determine the effect of three kinds of surface treatment on the bending strength of porcelain.Methods and Materials Five kinds of porcelain to be tested are (1) (2) vita shoulder porcelain with plasticizing liquid as binder, (3) vita shoulder porcelain with silica sol as binder, (4) Crystar shoulder porcelain using distilled water as a binder, (5) Crystar shoulder porcelain using a silica sol as a binder, and porcelain using a plasticizer as a binder as a control. Each system was individually made 30 A sample of the metal-coated porcelain used for the experiment contained the following three layers: (1) a 0.3-mm-thick gold-palladium alloy substrate, (2) a 0.3-mm-thick opaque porcelain layer, Mixtures Each containing 30 samples of the system and then divided into 10 subgroups of 10. Subgroups received the following different surface treatments: (1) self-glazing, (2) glazing, (( 3) Polishing itself after glazing Results The maximum force of rupturing porcelain in each sample was recorded, and these raw materials were input into a computer for statistical analysis, and it was found that distilled water
