Mean and SD of planned and postoperative distances defined for each patient: apex of the cusp of 43 and 33 for the right and left sides and the lower edge of the chin (Δ 43-chinR; Δ 33-chinL); lower edge of the right and left mental foramen and the osteotomy (Δ foramenR-chinR; Δ foramenL-chinL); mandibular lingual fossa and pogonion (Δ lingual fossa-pog).
