Facial asymmetry may originate from mandibular deviation combined with secondary maxillary compensation in vertical dimension, which can lead to occlusal plan canting. Two-jaw surgery would be an ideal choice for these cases in the past. Nowadays, using mini-implants to intrude elongated maxillary teeth to correct the occlusal plane canting could simplify the surgical plan into one-jaw surgery. In this case, a 30 y/o female was diagnosed with skeletal Class I malocclusion with mandibular deviation to left side combined with occlusal plane canting. The canted occlusal plane was corrected by intrusion of upper right posterior teeth with miniplate and minisrew first, and then one-jaw surgery for side shift and setback of mandible was performed. It took 17.5 months to have symmetric and pleasing facial profile, and good dental relationship. The patient was satisfied with the treatment outcome. Benefits of mini-implants application in pre-orthognathic surgical preparation are reviewed and discussed.
