A common technique for fixation of facial prostheses is the use of skin adhesives. The present study compared the tensile bond strength of five RTV-silicone elastomers used with four different skin adhesives to human skin. The elastomers were: Silskin II, MDX4-4210, Cosmesil, Cosmesil HC2, and RS 330 T-RTV. The adhesives were: Dow Corning 355 medical adhesive, PSA 1, Daro, and 9874 3M double-coated medical tape. The RTV silicones were cured as described by the manufacturer, fixed in circular metal holders, and glued to the skin (inner aspect of forearm) with the various adhesives. The specimens were pulled off 20 seconds after fixation by use of a universal testing machine with a crosshead speed of 1 mm/minute. Eight specimens of each silicone and adhesive combination were tested, and a mean bond strength was calculated for each combination and compared by Duncan's multiple range test on a personal computer. Significant differences were observed among the various combinations of silicones and adhesives. Dow Corning 355 adhesive showed the highest bond strength with all materials, and the medical tape had the lowest. Differences between the RTV silicones were also significant. The strongest bond with all adhesives was MDX4-4210 elastomer and the weakest for RS 330 T-RTV elastomer.
面部假体固定的一种常用技术是使用皮肤粘合剂。本研究比较了五种室温硫化(RTV)硅酮弹性体与四种不同皮肤粘合剂用于人体皮肤时的拉伸粘结强度。这些弹性体分别是:Silskin II、MDX4 - 4210、Cosmesil、Cosmesil HC2和RS 330 T - RTV。粘合剂分别是:道康宁355医用粘合剂、PSA 1、Daro和3M 9874双面医用胶带。RTV硅酮按照制造商的说明进行固化,固定在圆形金属支架中,并用各种粘合剂粘贴到皮肤(前臂内侧)上。使用十字头速度为1毫米/分钟的万能试验机在固定20秒后将标本拉开。对每种硅酮和粘合剂组合的八个标本进行测试,并计算每种组合的平均粘结强度,然后在个人计算机上通过邓肯多重极差检验进行比较。在硅酮和粘合剂的各种组合之间观察到显著差异。道康宁355粘合剂与所有材料的粘结强度最高,而医用胶带的粘结强度最低。RTV硅酮之间的差异也很显著。与所有粘合剂粘结最强的是MDX4 - 4210弹性体,而RS 330 T - RTV弹性体最弱。
