| 摘 要： | 目的 比较伴口呼吸安氏Ⅱ类1分类错患儿与正常儿童的牙颌颅面硬组织横向结构的差异,为临床
诊断及选择合理的治疗方案提供理论依据。方法 借助头颅后前位X线头影测量,对12例伴口呼吸的安氏Ⅱ类1
分类错患儿的牙颌颅面硬组织结构进行测量分析,并与15例正常儿童相应结构进行分析比较。结果 伴口
呼吸安氏Ⅱ类1分类错患儿的上颌基骨宽度、上磨牙间距、下尖牙间距及骨性鼻腔宽度明显低于正常儿童
(P<0·01);与正常相比,错患儿的下颌骨宽度、下磨牙间距的测量值也低于正常儿童(P<0·05)。结论 口呼
吸可引起儿童牙颌面横向结构上发育的异常,临床诊治时应对此异常给予考虑。

| Abstract: | OBJECTIVE: To evaluate the craniofacial characteristics of the Class II malocclusion patients with mouth-breating by posteroanterior cephalometry. METHODS: To measure craniofacial width of the 12 Class II malocclusion patients with mouth-breathing, and to compared these measures with corresponding measures in a group of normal children. RESULTS: The width of the maxillary base bone (J-J) was less than that in normal children significantly (P < 0.01). The mouth-breathing children's upper and lower arch width (at first molar and cuspid) were comparatively narrower, and lateronasal width (Lap-Lap) was narrower too. CONCLUSION: Mouth breathing may lead to craniofacial morphological abnormal development in craniofacial transverse structures. |
