Skeletal Bimaxillary Protrusion: Combined Surgical and Orthodontic Approach – A Case Report

Abstract

Bimaxillary protrusion is one of the commonly seen skeletal deformity in Indian population. This skeletal
condition is typically characterized by proclined and protruding anterior teeth with everted lips. If this
condition is associated with macroglossia or any parafunctional habits like tongue thrusting or thumb
sucking, an anterior open bite is often found. Minor discrepancies can be managed by orthodontic treatment
alone by extracting all first premolars and retracting the anterior segment. But in severe skeletal cases,
orthognathic surgery along with pre-and post-surgical orthodontics is the best option to get the ideal result.
This article describes the case of a female patient with bimaxillary protrusion. The patient had a convex
profile, anterior open bite, and incompetent lips. Chin had a relative deficiency with hyperactive mentalis
muscle. On patients’ consent and willingness for a shorter course of the treatment period, surgery first
approach was planned. Within seven months of the total treatment period, a remarkable change in facial
profile and a pleasing anterior occlusion was achieved.
