摘要/Abstract

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 ClassⅡ1malocclusion patientswithmouth-breating by posteroanterior cephalometry.Methods　To measure craniofacial width of the 12 ClassⅡ1malocclusion patients with mouth- breathing, and to compared these measureswith correspondingmeasures 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 archwidth (at firstmolar and cuspid) were comparatively narrower, and lateronasalwidth (Lap-Lap) was narrowertoo. Conclusion　Mouth breathing may lead to craniofacial morphological abnormal development in craniofacial transverse structures.
