Objective: the purpose of this study was to evaluate the opaque effect of 3 resins by covering dental alloys and the effects of the shade of all-ceramic materials.
目的：观察3种树脂，不同层厚下对齿科合金的遮色效果，及对全瓷冠颜色的影响。
All parts in contact with the media are structural ceramic materials, their chemical stability and high hardness (Rockwell hardness HRC90), second only to diamond.
所有与介质接触的部分均为结构陶瓷材料，其化学稳定性及硬度极高(洛氏硬度HRC90)，仅次于金刚石。
With the use of an inverter on the cooling fan, the oven controllers remove all moisture in the ceramic materials to ensure a stable, oxide free delivery.
随着对冷却风扇上逆变器的使用，烤箱控制器消除了陶瓷材料的所有水分，以确保稳定，氧化物自由的传送。
