运用锥形束CT诊断上下颌横向发育不调的研究进展

Progress in the diagnosis of maxillomandibular transverse deficiency by cone beam CT

上下颌横向发育不调是导致错畸形的重要因素,临床上常表现为后牙反、牙列拥挤、腭盖高拱、Wilson曲线过深、上颌磨牙颊倾、下颌磨牙舌倾等。本文就近年来上下颌横向发育不调在锥形束CT上的诊断方法、诊断标准的研究现状作一综述。

Maxillomandibular transverse deficiency is an important factor leading to malocclusion. Clinically, it is often manifested as posterior crossbite, crowded dentition, exaggerated curve of Wilson, buccal tipping maxillary molars, lingual tipping mandibular molars and so on. In this paper, the diagnosis of maxillomandibular transverse deficiency using cone beam CT are reviewed.
