Treatment of a Class I malocclusion with severe bimaxillary protrusion.
This report describes the treatment of a 20-year-old woman from Nigeria who had severe bimaxillary dentolveolar protrusion. The main issue in determining the appropriate treatment plan was the severity of the dentoalveolar protrusion. Four first premolars were extracted to reduce lip procumbancy. The change in the patient's facial esthetics was dramatic. Significant retraction of the upper and lower lips was achieved, and lip eversion and dentoalveolar protrusion were significantly improved. As the lips were retracted, mentalis strain was reduced; this improved chin projection. This case report was presented at an AAO meeting as part of the ABO student case display. It was chosen by committee to be published in the AJO-DO.
