The mean tensile/peel bond strengths were evaluated for three types of aesthetic brackets (a ceramic-reinforced bracket and two generations of a ceramic/polycarbonate combination bracket). These were found to be significantly lower than the mean tensile/peel bond strength of a convention foil-mesh stainless steel bracket base. Failure of the ceramic-reinforced polycarbonate brackets occurred predominantly by fracture of the tie wings during testing. With the ceramic/polycarbonate combination brackets, the majority of the specimens failed due to separation of the ceramic and polycarbonate parts of the bracket.
对三种类型的美观托槽（一种陶瓷增强托槽和两代陶瓷/聚碳酸酯组合托槽）进行了平均拉伸/剥离粘结强度评估。发现这些托槽的平均拉伸/剥离粘结强度显著低于传统箔网不锈钢托槽底座的平均拉伸/剥离粘结强度。在测试过程中，陶瓷增强聚碳酸酯托槽的失效主要是由于结扎翼断裂。对于陶瓷/聚碳酸酯组合托槽，大多数试样因托槽的陶瓷部分和聚碳酸酯部分分离而失效。
