Title:
力反応歯列矯正ブラケット、並びに力反応歯列矯正ブラケットを使用するシステムおよび方法
Document Type and Number:
Japanese Patent JP2007537824
Kind Code:
A
Abstract:
Force magnitudes and/or directions may be determined objectively using orthodontic brackets having an elastomeric member which allows one portion of the bracket to be resiliently moveable relative to at least on other portion of the bracket. In a preferred embodiment, the brackets include a lower base member, an upper bracket member, and an elastomeric layer interposed between the lower base and upper bracket members. The orthodontic bracket is advantageously employed as part of a system whereby the orthodontic bracket includes a force indicator which distorts in response to relative movement between the at least one and other portions of the bracket to provide an indication of force applied to the bracket. An optical detector may be provided to optically detect the indicator and issue an output signal indicative of the relative resilient movement between the lower base and upper bracket members. A processor receives the output signal from the optical detector to provide an indication of magnitude and/or direction of the force applied to the upper bracket member.
