美观的托槽用陶瓷、树脂等材料制成,其抗磨损强度、与树脂间界面结合强度、对弓丝的摩擦抵抗力等机械性能得到改善。方丝常用金属材料制成,为了改善美观,有几家公司生产出一种在金属弓丝表面应用白色Teflon(聚四氟乙稀)或环氧树脂的美观弓丝。当前推出的一种更为美观的新型弓丝 Beautiful brackets made of ceramic, resin and other materials, its abrasion resistance, bonding strength with the interface between the resin, the friction resistance of the arch wire and other mechanical properties are improved. Square wire is often made of metal, and in order to improve the appearance, several companies have produced an aesthetically pleasing wire that uses white Teflon (polytetrafluoroethylene) or epoxy on the surface of a metal wire. The current launch of a more beautiful new arch wire
