Significant differences in osteotomy angles were demonstrated for in\u2010house planning (<jats:italic>p<\/jats:italic>\u2009=\u20090.0391). Commercial planning was superior to in\u2010house planning for total mandibular deviation (<jats:italic>p<\/jats:italic>\u2009=\u20090.0217), intersegmental space volumes (<jats:italic>p<\/jats:italic>\u2009=\u20090.0035), and lengths (<jats:italic>p<\/jats:italic>\u2009=\u20090.0007). No significant difference was found between the two planning solutions in terms of intersegmental ossification and the incidence of wound healing disorders. In\u2010house planning took less time than commercial planning (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001).
