目的:介绍一种临床上行之有效的矫治下颌磨牙颊舌向倾斜错位的方法,并探讨其在矫治过程中的特点。方法:对8例下颌磨牙颊向或舌向倾斜错位的患者,采用简易半固定舌弓配合方丝弓矫治技术在矫治初期进行矫治。结果:在矫治初期,应用简易半固定舌弓能快速成功地矫治下颌磨牙颊向或舌向倾斜错位。结论:简易半固定舌弓在矫治过程中固位和稳定性较好,能很好地控制下磨牙颊舌向位置,并缩短固定矫治的疗程,对下颌牙弓前牙区的形态影响较小。

PURPOSE: Introducing an effective corrective therapy for linguoclination or buccoclination of the mandibular molars. METHODS: Using a simple semi-fixed lingual arch combined with the edgewise technology to correct 8 cases with linguoclination or buccoclination of the mandibular molars. RESULTS: Using the simple semi-fixed lingual arch can correct the malposition of mandibular molar's linguoclination or buccolination quickly and successfully.CONCLUSION: The simple semi-fixed lingual arch can fix properly the buccolingual position of the mandibular molar and can shorten the course of the fixed orthodontic therapy.In addition,this method exerts less impact on the contour of the anterior mandibular arch.
