At the occlusional level, pooled change in overbite was 0.21 mm in maxillary surgery, 0.37 mm in bimaxillary surgery, and \u22120.32 mm in mandibular surgery. At the skeletal level, pooled sella\u2013nasion\u2013Point A angle (SNA) was \u22120.12 degrees in bimaxillary surgery, \u22120.37 degrees in maxillary surgery and \u22120.20 degrees in mandibular surgery. The sella\u2013nasion to palatal plane angle (SNPP) relapsed to a statistically significant degree in all samples received single maxillary surgery. Relapse of the sella\u2013nasion\u2013Point B angle (SNB) was 0.47 degrees in mandibular setback, \u22121.8 degrees in mandibular advancement, and \u22120.48 degrees in maxillary surgery. The Sella\u2013Nasion to mandibular plane angle (SNMP) relapsed more in procedures involving bilateral sagittal split osteotomy than in other procedures. As for dento-alveolar changes, intrusion of molars and extrusion of incisors took place in most patients.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Bimaxillary surgery produced the most beneficial post-operative increase in overbite, maxillary surgery led to a lesser but still positive overbite change, and mandibular surgery correlated with some extent of relapse. Skeletally, bimaxillary surgery was more stable than maxillary surgery at both SNA and SNPP; SNB was more stable in mandibular setback than advancement; and SNMP was unstable in both mandibular and bimaxillary surgeries versus maxillary surgery with comparable surgical changes.
