Fixed orthodontic attachments/appliances work as a medium to transfer the force applied to the teeth. In bonded types, several factors affect the attachment bond strength and their clinical success. The primary approach for increasing the bond strength focused on altering the time and concentration of acid etching; however, the results showed that these changes might increase susceptibility to enamel decalcification. The bonding mechanism of orthodontic attachments may be chemical, mechanical, or a combination of both. Most attachment bonding surfaces (ABSs) have no chemical bond to resin composites. Hence, mechanical retention plays a major role. Developing more bonding surfaces by increasing the macroscopic size of the attachments has esthetic and hygienic limitations, so the ABS design plays a more important role in maintaining and improving the bond strength. In this research, different ABS designs are reviewed and categorized according to manufacturing methods and their features.
固定正畸附件/矫治器作为传递施加于牙齿上力的媒介。在粘结型中，有几个因素会影响附件的粘结强度及其临床成功率。提高粘结强度的主要方法集中在改变酸蚀的时间和浓度；然而，结果表明这些改变可能会增加牙釉质脱矿的易感性。正畸附件的粘结机制可能是化学的、机械的或两者的结合。大多数附件粘结表面（ABS）与树脂复合材料没有化学键合。因此，机械固位起主要作用。通过增加附件的宏观尺寸来开发更多的粘结表面存在美观和卫生方面的限制，所以ABS设计在维持和提高粘结强度方面发挥着更重要的作用。在本研究中，根据制造方法及其特点对不同的ABS设计进行了综述和分类。
