Abstract

Objective: The aim of this study was to compare the tie wing fracture resistance of 4 different manufacturers' ceramic brackets currently on the market.

Methods: The tie wings of ceramic brackets from 4 manufacturers were tested with 10 samples in each group. The brackets were Ormco Symetri, 3M Clarity, American Radiance Plus, and Dentsply Ovation S. The brackets were mounted and fixed in a universal testing machine. A stainless steel ligature wire was looped around a tie wing and the mean tensile strength was both tested and recorded.

Results: There was a significant overall difference in tensile strength among the 4 groups (P < .0001) with the 3M Clarity brackets having the highest MPa. When the groups were compared to each other, they also showed a significant difference in mean tensile strength with the exception being the American Radiance Plus and Ormco Symetri brackets.

Conclusion: Test results concluded that the 3M Clarity brackets had the highest resistance to tie wing fracture, while the Dentsply Ovation S brackets had the lowest resistance.

不同陶瓷支架系翼抗断裂性能的比较。

目的:比较目前市场上4种不同厂家的陶瓷托槽的系翼抗断裂性能。方法:对4家生产厂家的陶瓷托槽扎翼进行检测，每组10个样品。支架为Ormco Symetri, 3M Clarity, American Radiance Plus和Dentsply Ovation s。支架安装并固定在通用测试机上。将一根不锈钢扎绳绕在扎翼上，测试并记录其平均抗拉强度。结果:4组间抗拉强度总体差异显著(P < 0.0001)，其中3M Clarity托槽MPa最高。当这些组相互比较时，除了美国Radiance Plus和Ormco Symetri支架外，它们的平均抗拉强度也有显著差异。结论:测试结果表明3M Clarity支架对系翼断裂的阻力最大，Dentsply Ovation S支架对系翼断裂的阻力最小。
