A dimethyl siloxane-triacetoxy terminated silane, Type A adhesive, can be modified with the base component of a medium grade polydimethyl siloxane with vinyl groups, MDX 4-4210, to produce more pliable maxillofacial prostheses. The mechanical properties of samples with various Type A adhesive/MDX 4-4210 ratios were determined. Addition of the MDX 4-4210 base decreased the hardness, modulus, and ultimate tensile strength, while the percentage elongation increased. The initial tear strength was relatively constant for the various ratios except for the 50/50 mix, where a 50% decrease was observed. The ability to obtain different mechanical properties by using various ratios of Type A adhesive and MDX 4-4210 could result in the production of maxillofacial prostheses which will more closely stimulate the properties of facial tissues.
A型粘合剂，一种二甲基硅氧烷-三乙酰氧基封端的硅烷，可以用含乙烯基的中等品级聚二甲基硅氧烷的基础组分MDX 4-4210进行改性，以生产更柔韧的颌面修复体。测定了具有不同A型粘合剂/MDX 4-4210比例的样品的机械性能。添加MDX 4-4210基础组分降低了硬度、模量和极限拉伸强度，而伸长率百分比增加。除了50/50的混合物（观察到其初始撕裂强度下降了50%）外，不同比例的初始撕裂强度相对恒定。通过使用不同比例的A型粘合剂和MDX 4-4210来获得不同机械性能的能力，可能会导致生产出更能模拟面部组织特性的颌面修复体。
