Debonding of plastic teeth from its denture base has been frequently experienced in our prosthetic practice. Three of nine products investigated have fulfilled the requirements for bonding according to ISO test 3336. Loading forces necessary to produce fractures varied between 170-810 N within the tooth and 80-230 N at the tooth-denture base interface. Comparative significances were noted for the mean breaking force against fracture and debonding when comparing the resistance of "Acry Rock" to the other eight materials tested. Maximizing the extension of the polymerization surface through a larger surface area of individual teeth seemed to be a significant factor in the determination of the debonding force necessary to produce fracturing.
在我们的修复实践中，塑料牙与义齿基托分离的情况屡见不鲜。在九种被研究的产品中，有三种符合ISO 3336测试的粘结要求。牙齿内部产生断裂所需的加载力在170 - 810 N之间，牙齿与义齿基托界面处为80 - 230 N。在比较“Acry Rock”与其他八种测试材料的抗力时，发现平均断裂力与断裂和脱粘之间具有显著差异。通过单个牙齿更大的表面积来最大化聚合表面的延伸，似乎是决定产生断裂所需脱粘力的一个重要因素。
