常规的软质丙烯酸树脂材料取决于增塑剂的使用以获得其顺应性。在含水环境中，增塑剂浸出，导致材料硬化。使用可聚合的增塑剂已被证明可以解决这个问题。开发了一种这样的材料，但在临床试验期间机械失效。本研究的目的是重新配制以生产具有改进强度的材料。三种不同的甲基丙烯酸酯单体与两种不同水平的增塑剂一起使用，每种单体混合物与相同的共聚物粉末以三种粉末/液体比率一起使用。测量了拉伸强度、撕裂能和硬度，并将结果与专利增塑丙烯酸树脂软衬里材料“Supersoft”进行了比较。所有实验材料的抗拉强度均高于原始帕克/布拉登材料。具有较高粉末/液体水平的30%增塑剂材料具有与“Supersoft”相同范围的强度、撕裂能和硬度值。已经生产出了具有改进强度的材料。(C)1998由Elsevier Science Ltd.出版。保留所有权利。
Conventional soft acrylic resin materials depend on the use of plasticisers for their compliance. In aqueous environments the plasticisers leach out causing the material to harden. Use of a polymerisable plasticiser has been shown to solve this problem. One such material was developed but failed mechanically during clinical trial. The aim of this study was to reformulate to produce a material with improved strength. Three different methacrylate monomers were used with two different levels of plasticiser, each monomer mix was used with the same copolymer powder at three powder/liquid ratios. Tensile strength, tear energy and hardness were measured and results compared with 'Supersoft', a proprietary plasticised acrylic resin soft lining material. All the experimental materials had a higher tensile strength than the original Parker/Braden material. The 30% plasticiser materials with the higher powder/liquid level had strength, tear energy and hardness values in the same range as 'Supersoft'. Materials of improved strength have been produced.
