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.
