Abstract

PURPOSE: Mid and lower facial convexity is more common in Oriental people than in Caucasian. Bimaxillary dentoalveolar protrusion is characterized by procumbent teeth, protruding lips, acute nasolabial angle, gummy smile, receding chin, facial convexity. Especially, pure maxillary dentoalveolar protrusion is less frequent than bimaxillary dentoalveolar protrusion. Therefore, it is important to make an accurate decision for the operation throughout the history taking, cephalogram, dental cast to arrive at accurate diagnosis and surgical plan.
METHODS
From December 2002 to June 2004, ten patients with maxillary dentoalveolar protrusion and microgenia were corrected by maxillary anterior segmental osteotomy and advancement genioplasty. 10 patients were analyzed by preoperative and postoperative clinical photography, posteroanterior and lateral cephalograms.
RESULTS
No major complications were occurred throughout the follow-up period except one of the over- recessed, otherwise most of the patients were satisfied with the result.
CONCLUSION
We could correct the occulusal relationship with teeth and improve lower facial profile, asthetically and functionally, by maxillary anterior segmental osteotomy and advancement genioplasty.
