MASDO was applied and the osteotomy line was drawn on the palate between the molars and premolars on both sides. One mini-screw was inserted in the planned position. Loosening of the mini-screw occurred at 12 weeks after the osteotomy. The premaxilla moved forward and the facial profile was improved after MASDO. We initially planned to alleviate dental crowding and create space for the restoration of No.15 and No.25 using the space produced by the MASDO produce. However, the patient wished to close the space without restoration, so the distracted space was subsequently closed by mesializing the molars
