This case report describes a novel method of combining lingual appliances and lingual arches to control horizontal problems. The patient, who was 25 years of age at her first visit to our hospital with a chief complaint of crooked anterior teeth, was diagnosed with skeletal Class II and Angle Class II malocclusion with anterior deep bite, lateral open bite, premolar crossbite, and severe crowding in both arches. She was treated with premolar extractions and temporary anchorage devices. Conventionally, it is ideal to use labial brackets simultaneously with appliances, such as a lingual arch, a quad-helix, or a rapid expansion appliance, in patients with complex problems requiring horizontal, anteroposterior, and vertical control; however, this patient strongly requested orthodontic treatment with lingual appliances. A limitation of lingual appliances is that they cannot be used with other conventional appliances. In this report, we present the successful orthodontic treatment of a complex problem using modified lingual appliances that enabled combined use of a conventional lingual arch.
本病例报告描述了一种结合舌侧矫治器和舌弓来控制水平问题的新方法。该患者初诊我院时25岁，主诉前牙不齐，被诊断为骨性II类、安氏II类错牙合，伴有前牙深覆牙合、侧方开牙合、前磨牙反牙合以及双侧牙弓严重拥挤。她接受了前磨牙拔除和临时支抗装置治疗。传统上，对于需要进行水平、前后向和垂直控制的复杂问题患者，理想的做法是在使用诸如舌弓、四螺旋扩弓器或快速扩弓器等矫治器的同时使用唇侧托槽；然而，该患者强烈要求使用舌侧矫治器进行正畸治疗。舌侧矫治器的一个局限性在于它们不能与其他传统矫治器联合使用。在本报告中，我们展示了使用改良舌侧矫治器成功治疗复杂问题的正畸病例，这种改良舌侧矫治器能够与传统舌弓联合使用。
