Abstract: Orthodontic adhesives are claimed which use polymeric filler particles with defined particle size characteristics. The particle size characteristics are controlled such that these adhesives provide comparable mechanical retention and cohesive strength of conventional orthodontic adhesives when used to bond orthodontic appliances to teeth. Because polymeric fillers are generally softer than inorganic fillers, these adhesives are easier to remove from the tooth than conventional adhesives after debonding an orthodontic appliance. Embodiments of the invention include both self-curing and two-part adhesives, packaged adhesive-coated orthodontic appliances, and methods for removing a cured adhesive from a tooth surface.

Abstract translation: 要求使用具有确定的粒度特性的聚合物填料颗粒的正畸粘合剂。 控制粒度特征，使得这些粘合剂当用于将正畸器具粘合到牙齿上时，提供了常规正畸粘合剂相当的机械保持性和内聚强度。 因为聚合物填料通常比无机填料柔软，因此在脱粘矫正器具之后，这些粘合剂比常规粘合剂更容易从牙齿上除去。 本发明的实施例包括自固化和两部分粘合剂，包装的粘合剂涂覆的正畸矫治器，以及从牙齿表面去除固化的粘合剂的方法。
