塑料托槽和陶瓷托槽一样，因为它们具有优异的美学，所以在各种情况下使用。然而，它们的机械性能仍然不确定。本研究的目的是确定在相同的金属丝载荷下，不同材料的美学托槽的变形和应力分布有何不同。使用数字图像相关方法，我们发现了以下内容：（1）塑料托槽的翼部应变在0.2%以内，陶瓷和金属托槽的翼部应变可以忽略不计，（2）具有不锈钢槽的聚碳酸酯托槽显示出比其他塑料托槽显著更小的位移，（3）塑料托槽与陶瓷托槽和不锈钢托槽在托槽翼的位移方面存在显著差异。
Plastic brackets, as well as ceramic brackets, are used in various cases since they have excellent esthetics. However, their mechanical properties remain uncertain. The purpose of this study was to determine how deformation and stress distribution in esthetic brackets differ among materials under the same wire load. Using the digital image correlation method, we discovered the following: (1) the strain of the wings of plastic brackets is within 0.2% and that of ceramic and metal brackets is negligible, (2) polycarbonate brackets having a stainless steel slot show significantly smaller displacement than other plastic brackets, and (3) there is a significant difference between plastic brackets and ceramic and stainless steel brackets in terms of the displacement of the bracket wing.
