The demand by patients considered for better esthetics during treatment should be seriously considered. With the introduction of fiberglass brackets one has tried to solve that problem. The purpose of this investigation was: 1. a microscopic examination of the slots of these fiberglass brackets after various periods of wearing; 2. an in vitro investigation of the adhesion of the fiberglass brackets in comparison to metal brackets; The following results were obtained: 1. There are remarkable differences in the slot dimensions between new fiberglass brackets and those which have been in the mouth for varying periods of time. 2. Ligating wires into fiberglass brackets may be difficult because of wing fractures. 3. There are significant differences regarding the adhesion of fiberglass brackets compared with metal brackets. Results of tests carried out under defined conditions (bonding, storage, time-factor) concluded that metal brackets behaved much more favourably; the adhesion of metal brackets was nearly ten times greater than that for fiberglass brackets.
在治疗过程中，应认真考虑患者对更佳美观效果的需求。随着玻璃纤维托槽的引入，人们试图解决这一问题。本研究的目的是：1. 对佩戴不同时长后的玻璃纤维托槽槽沟进行显微镜检查；2. 与金属托槽相比，对玻璃纤维托槽的黏附力进行体外研究。获得了以下结果：1. 新的玻璃纤维托槽与在口腔中佩戴不同时长的托槽在槽沟尺寸上存在显著差异。2. 由于翼板断裂，将结扎丝置入玻璃纤维托槽可能会很困难。3. 与金属托槽相比，玻璃纤维托槽的黏附力存在显著差异。在规定条件（粘结、储存、时间因素）下进行的测试结果表明，金属托槽的表现更为良好；金属托槽的黏附力几乎是玻璃纤维托槽的十倍。
