下颌前伸装置(mandibular advancement devices,MAD)通过导下颌向前下再定位,增大患者口咽通气道,正在成为治疗鼾症及轻度睡眠呼吸窘迫暂停患者的一种选择。本文旨在调查MAD治疗此类患者时对牙(牙合)可能产生的正畸性副作用,并分析不同MAD设计所产生的差异。 材料与方法 本研究将戴用MAD的75位鼾症及轻度睡眠呼吸窘迫暂停患者纳入试验组,另17位不能忍受MAD的患者作为对照。在试验组中47位 Mandibular advancement devices (MADs), which move the mandibular advancement anteriorly and augment the oropharyngeal airway, are becoming an option for patients with snoring and mild-sleep-induced respiratory distress. The purpose of this article is to investigate possible orthodontic side effects of occlusion on MAD in the treatment of such patients and to analyze differences in different MAD designs. Materials and Methods In this study, 75 patients with MND who had snoring and mild sleep-induced respiratory distress were included in the study group and the other 17 patients who could not tolerate MAD as controls. 47 in the experimental group
