Distalization of mandibular molars has always been one of the most challenging treatment objectives in clinical orthodontics, particularly in adult patients.(1) If the posterior space is sufficient and alveolar bone is available, however, lower molar distalization is a viable option in Class III nonextraction therapy. Several intraoral appliances have been introduced for this purpose, including the lip bumper,(2,3) a distal extension lingual arch,(4) the Jones Jig,(*5) the Franzulum appliance,(6) and the multiloop edgewise archwire (MEAW),(7) Today, molars can be moved distally using miniscrew anchorage, with no need for patient cooperation, to camouflage a Class III malocclusion or relieve crowding without premolar extractions.
下颌磨牙远中移动一直是临床正畸治疗中最具挑战性的治疗目标之一,尤其是在成年患者中。(1)然而,如果后部间隙充足且有可用的牙槽骨,在下颌III类不拔牙治疗中,下颌磨牙远中移动是一个可行的选择。为此已经引入了几种口内矫治器,包括唇挡,(2,3)远中延伸舌弓,(4)琼斯矫治器,(5)弗兰祖勒矫治器,(6)以及多曲方丝弓(MEAW),(7)如今,使用微螺钉支抗可以在无需患者配合的情况下将磨牙远中移动,以掩饰III类错牙合或在不拔除前磨牙的情况下缓解拥挤。
