甲基丙烯酸甲脂单体与聚合体粉末的混合物,用于做牙科材料。该材料问世以后至今被广泛地用作于义齿基托和人工牙。我们采用高压水浴加热法固化甲基丙烯酸甲酯塑料使之成为人工牙及义齿基托。在制造可摘局部义齿和全口义齿时,有时发现基托局部或大部分区域出现白化区,并在此“白化区”内伴有酥脆现象产生。我们采用开盒后即将义齿放入温水中浸泡的方法,较好的解决了白化现象的产生,此方法对制造合格的义齿基托是有意义的。 Mixtures of methylmethacrylate monomers and polymer powders for dental materials. The material has been widely used as denture base and artificial tooth until now. We use high-pressure water bath heating curing methyl methacrylate plastic artificial teeth and denture base. In the manufacture of removable partial dentures and complete dentures, it is sometimes found that the base part or most of the area whitening area, and in this “white area” accompanied by crisp phenomenon. We use the method of putting the denture into warm water after opening the box, which can better solve the albino phenomenon. This method is of great significance to the manufacture of qualified denture base.
