This investigation compared the wear resistance of three "improved" resin posterior denture tooth formulations with two conventional products on a mechanical toothbrush abrasion machine. The ability of the teeth to resist this type of abrasion was evaluated by determination of the weight loss during 339 hours of brushing with firm nylon bristle toothbrushes. All brands exhibited negligible loss, with the conventional brands performing better than the "improved" formulations.
本研究在机械牙刷磨损试验机上，比较了三种“改良型”树脂后牙义齿牙齿配方与两种传统产品的耐磨性。通过测定使用硬尼龙刷毛牙刷刷牙339小时期间的重量损失，评估牙齿抵抗这种磨损的能力。所有品牌的重量损失均微不足道，传统品牌的表现优于“改良型”配方。
