Dentoalveolar characteristics in skeletal class I patients with excessive overjet / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the dentoalveolar characteristics in skeletal class I patients with excessive overjet.</p><p><b>METHODS</b>Ten cephalometric measurements of 60 skeletal class I patients with excessive overjet were analyzed.</p><p><b>RESULTS</b>Compared with patients with normal overjet, 1-SN, 1-NA and MxAAH were significantly increased in excessive overjet group I (overjet 3 - 5 mm) and 1-SN, 1-NA and MxAAH were significantly increased in excessive overjet group II (overjet 5 - 7 mm).</p><p><b>CONCLUSIONS</b>The protrusion and tipping of maxillary incisor, and absence of compensatory proclination of mandibular incisor may be the factors, caused skeletal class I excessive overjet. Increased height of anterior maxillary anterior alveolar process was the compensatory change in skeletal class I patients with excessive overjet.</p>
