Plastic teeth are preferred as functional portions with acrylic denture base material. The resin teeth have become the integral part of the denture by their chemical bonding with the base. But several factors effect the bonding: faulty boil-out procedures, residual wax on ridge-laps of the teeth, careless application of tin-foil substitutes to the teeth. On the other hand, grinding the glossy ridge-lap surface, painting the teeth with monomer or a solvent, preparing retention grooves on the ridge-lap portion of the teeth effectively lock the teeth to the denture base. The purpose of this research was to evaluate the bond strengths of the acrylic resin teeth and denture base material with retention grooves on the ridge-lap portion of the teeth. As a result of this study, bond strength between resin teeth and the denture base material is increased by the mechanical retention applied on the ridge-lap portion of the teeth.
塑料牙作为义齿基托材料的功能部分更受青睐。树脂牙通过与基托的化学键合已成为义齿的组成部分。但有几个因素会影响这种结合：煮沸处理不当、牙嵴面残留蜡、在牙上粗心地涂抹锡箔替代品。另一方面，打磨光滑的牙嵴面、用单体或溶剂涂刷牙齿、在牙嵴面部分制备固位沟可有效地将牙齿固定在义齿基托上。本研究的目的是评估带有牙嵴面固位沟的丙烯酸树脂牙与义齿基托材料之间的粘结强度。这项研究的结果表明，通过在牙嵴面部分施加机械固位，树脂牙与义齿基托材料之间的粘结强度得以提高。
