Abstract

A dimethyl siloxane triacetoxy terminated silane, Type A adhesive, was modified with the base component of a medium grade polydimethyl siloxane with vinyl groups, MDX 4-4210, to produce a more pliable maxillofacial prosthesis. Force-displacement curves of various ratios of Type A adhesive/MDX 4-4210 were determined and compared with force-displacement curves obtained from human subjects. Within the force range of 0.4 to 1.2 N, the force-displacement slopes obtained on human subjects compared favourably with some of the Type A adhesive/MDX 4-4210 test specimens. The force-displacement slopes for the elastomers and humans were not in agreement for forces below 0.4 N.

摘要

一种A型粘合剂，端基为三乙酰氧基二甲基硅氧烷，用含乙烯基的中等粘度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A型粘合剂/ MDX 4-4210不同比例的力-位移曲线，并与从人体受试者获得的力-位移曲线进行比较。在0.4至1.2 N的力范围内，人体受试者获得的力-位移斜率与一些A型粘合剂/ MDX 4-4210测试样品相比具有优势。对于低于0.4 N的力，弹性体和人体的力-位移斜率不一致。
