Abstract:
This case report shows the need to extract four first premolars in addition to orthognathic surgery, even though the initial treatment plan involved a nonextraction strategy. The extractions were necessary to reduce maxillary dental protrusion and proclination and also to recover from the mandibular incisor proclination that occurred as a consequence of leveling the mandibular arch.
