支梨熔模的制作是支架铸造技术的关键,要完成准确良好的铸造支架,首先要制作准确良好的熔模。支架熔模通常大都采用铺蜡法或滴蜡法制作的,也叫蜡模。采用脱模法制作的支架蜡模,在制作过程中容易变形。笔者对前牙缺失深覆(牙合)者的铸造基托及小型铸造支架,采用自凝塑料制作熔模,克服了蜡模易变形的缺点。现以(?)缺失为例,介绍制作方法如 The production of pear melt mold is the key to stent casting technology. To complete the accurate and good casting support, we must first make the accurate and good investment mold. Stent stencil usually used mostly wax or wax law produced, also known as wax model. The stripping wax mold made by the stripping method is easy to deform in the manufacturing process. The author of the deep missing on the anterior teeth (Occlusal) who cast base and small casting stents, the use of self-curing plastic melt making mold to overcome the shortcomings of deformation of the wax mold. Now (?) Missing as an example, describes the production methods such as
