Introduction The objective of this study was to report the correction of a maxillary transverse discrepancy in an adult patient using Le Fort I osteotomy procedure associated with a bone-borne maxillary distractor device. Both the indications, advantages of the procedure and the use protocol were highlighted. Case Presentation The results showed that the bone-borne distractor promoted the correction of maxillary transverse discrepancy with minimal side effects on the maxillary posterior teeth.
