摘要： In an orthodontic appliance fit into the mouth, at least either one of an orthodontic bracket or an arch wire is composed of a composite resin. A reinforcing member is provided at a slot of the bracket and exposed to an inner wall surface of the slot. The reinforcing member is extended into tie wings which are formed as being extended toward the gingival side of the slot and towards the occlusal side. The composite resin is a resin, e.g., a polymer alloy, in which two or more kinds of resin having contrary capacities, i.e., durability and adhesiveness, are blended. Further, a thermoplastic elastomer (TPE) is dispersed into a matrix resin to accomplish the strength and the solvent crack prevention, which are difficult to consist with each other. Dispersing TPE into the matrix resin is one kind of polymer alloying, and thus obtained resin is the composite resin.

摘要翻译： 在矫正装置中，适合于口腔，正畸托架或拱形线中的至少一方由复合树脂构成。 加强构件设置在支架的狭槽处并暴露于槽的内壁表面。 加强构件延伸成领带翼，其形成为朝向狭槽的牙龈侧并朝向咬合侧延伸。 复合树脂是混合具有相反容量的两种或更多种树脂，即耐久性和粘合性的树脂，例如聚合物合金。 此外，将热塑性弹性体（TPE）分散到基质树脂中以实现难以彼此组合的强度和溶剂裂纹的防止。 将TPE分散在基体树脂中是一种聚合物合金化，因此得到的树脂是复合树脂。
