Abstract

Design characteristics (area of bonding, mesh size, and type) and bond strength of fourteen commercial direct-bonding metal bases with commercially attached brackets were evaluated. Tensile bond strength was measured with two direct-bonding adhesives, using plastic and natural teeth as substrates. Statistically significant differences in bond strength were observed among the bases, but bond strength was independent of nominal area and mesh size of the bases. Bond failures occurred most frequently at the base-adhesive interface of the metal bases. Damage caused by spot-welding of brackets to bases was implicated as a factor affecting bond strength.

摘要

对14种带有商业附着托槽的市售直接粘结金属基底的设计特征（粘结面积、网眼尺寸和类型）及粘结强度进行了评估。使用塑料和天然牙作为基底，用两种直接粘结粘合剂测量拉伸粘结强度。在基底之间观察到粘结强度存在统计学上的显著差异，但粘结强度与基底的标称面积和网眼尺寸无关。粘结失败最常发生在金属基底的基底-粘合剂界面处。托槽点焊到基底造成的损伤被认为是影响粘结强度的一个因素。
