采用组合磨损试验研究了咬合周期和刷牙周期对复合树脂磨损的影响，该试验交替进行咬合和牙刷磨损测试。测量磨损体积和最大磨损深度，以评估两种不同周期（咬合周期：50 和 150 周期；刷牙周期：20 和 50 周期）的四种组合下的磨损。对于由较大且形状不规则的填充颗粒组成的复合树脂APX，其磨损体积和磨损深度随着咬合周期的次数显着增加。复合树脂 Z100 由相对较小且形状不规则的填充颗粒组成，其磨损值随着刷牙和咬合周期的增加而显着增加。对于由小的、不规则形状的无机填料颗粒和大的有机填料颗粒组成的复合树脂SRE，在较低的刷牙周期下，其磨损体积随着咬合周期显着增加。对于由球形无机填料颗粒和大有机填料颗粒组成的复合树脂SDX，其磨损不受刷牙和咬合周期增加的影响。
The effects of occlusal cycles and brushing cycles on wear of composite resins were investigated using a combined wear test, which carried out occlusal and toothbrush wear tests alternately. Worn volume and maximum worn depth were measured to evaluate wear under four combinations of two different cycles (occlusal cycles: 50 and 150 cycles; brushing cycles: 20 and 50 cycles). With composite resin APX, which consisted of relatively large and irregular-shaped filler particles, its worn volume and worn depth significantly increased with the number of occlusal cycles. With composite resin Z100, which consisted of relatively small and irregular-shaped filler particles, its wear values significantly increased with both brushing and occlusal cycles. With composite resin SRE, which consisted of small, irregular-shaped, inorganic filler particles and large organic filler particles, its worn volume significantly increased with the occlusal cycle when under a lower brushing cycle. With composite resin SDX, which consisted of spherical inorganic filler particles and large organic filler particles, its wear was not influenced by increases in both brushing and occlusal cycles.
