    • An orthodontic headgear assembly which incorporates at least one magnetic release mechanism. In one embodiment, the headgear assembly generally includes an inner bow, an outer bow interconnected with the inner bow, a mechanism for generating and applying a force to the ends of the outer bow which is thus transferred to the patient's teeth, and a magnetic release mechanism which is positioned between each end of the outer bow and the force generating mechanism. When a given magnetic release mechanism is subjected to a force of a predetermined magnitude, the mechanism disconnects adjacent portions of the headgear assembly to reduce the potential for the adverse effects on the patient due to snapback of the outer and/or inner bow when at least a portion of the force is removed from the headgear assembly.
    • 包含至少一个磁性释放机构的正畸头饰组件。 在一个实施例中,头带组件通常包括内弓,与内弓互相连接的外弓,用于产生力并施加到外弓的端部的机构,由此将其转移到病人的牙齿上, 位于外弓的两端和力产生机构之间的机构。 当给定的磁性释放机构受到预定大小的力时,该机构使头套组件的相邻部分断开,以减少由于至少在外部和/或内部弓的回弹时对患者的不利影响的可能性 力的一部分从头带组件移除。
