Abstract:
OBJECTIVETo investigate the dentoalveolar characteristics in skeletal class I patients with excessive overjet.
METHODSTen cephalometric measurements of 60 skeletal class I patients with excessive overjet were analyzed.
RESULTSCompared 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).
CONCLUSIONSThe 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.
