At least one manufacturer claims that contamination of denture teeth with tinfoil substitute during processing is not detrimental. The purpose of this study was to determine whether tinfoil substitute contamination has any significant effect on the bond strength between acrylic resin denture teeth and their processed acrylic resin base. Eighty acrylic resin maxillary central incisors were processed to denture base material. The experimental group had the denture tooth ridgelap area contaminated with tinfoil substitute. The control group was not contaminated. The bond strength of the two groups was tested. The results indicate that contamination with tinfoil substitute significantly reduces the bond strength of acrylic resin denture teeth bonded to their denture base.
至少有一家制造商声称，义齿牙在加工过程中被锡纸替代品污染并无损害。本研究的目的是确定锡纸替代品污染是否对丙烯酸树脂义齿牙与其加工的丙烯酸树脂基托之间的粘结强度有任何显著影响。将80颗丙烯酸树脂上颌中切牙加工成义齿基托材料。实验组的义齿牙牙槽嵴贴合区域被锡纸替代品污染。对照组未被污染。测试了两组的粘结强度。结果表明，锡纸替代品污染显著降低了粘结到义齿基托上的丙烯酸树脂义齿牙的粘结强度。
