Abstract

DEPCT65 The present invention provides a new orthodontic appliance. The appliance comprises a base member attached to two or more screws implanted in the median palatine suture of the palatine bone, an arm member having a first connection member connected to the base member and a second connection member located on the palatine side of the tooth, and a retraction member made of a flexible wire material that retraction the tooth as the target of the retraction. Herein, the retraction member has a base member attached to a second connection member, a retraction anchorage attached to a bracket attached to a target of the retraction base member, and a retraction force generation member mounted between the retraction base member and the retraction bracket and acting to transmit a reverse and forward rotational force or a forward and backward rotational force to the bracket through the retraction bracket. The retraction bracket has a bent portion such that the wire material extending along the tooth set is plastically deformed and bent toward the root side of the tooth, and a bent portion attached to a palatal projection in the bracket. ----------------------------------------------------------- The invention provides a novel orthodontic appliance. The appliance comprises a base member attached to two or more screws implanted in the median palatine suture of the palatine bone, an arm member having a first connection member connected to the base member and a second connection member located on the palatine side of the tooth, and a retraction member made of a flexible wire material that retraction the tooth as the target of the retraction. Herein, the retraction member has a base member to which a ball attaches to a second connection member, a retraction retainer hooked onto a bracket to which the ball attaches to a target of the retraction located at a distance from the base member, and a retraction member hooked onto a bracket to which the ball attaches to a target of the retraction located at a distance from the base member, and a retraction member hooked onto a bracket to which the ball attaches to the bracket and transmits a reverse and forward rotational force or a reverse and forward rotational force to the bracket through the retraction retainer. The retraction retainer has a curved ball portion in which the wire material extending along the tooth set is plastically deformed and bent toward the root side of the tooth, and a ball portion hooked onto a projection extending to the palatal side of the bracket [Figure 7].
