AMO: Wunderer Technique

The anterior maxillary osteotomy (AMO) is employed primarily to reposition the anterior dento-osseous segment posteriorly (setback). It is also used to move the segment superiorly or inferiorly as indicated. Wunderer formed a vestibular pedunculated anterior maxillary segment, while foregoing Wassmund’s palatal tunneling and palatal perfusion by forming a palatal mucosal flap. This significantly improved the overview of the palatal osteotomy zone, which was anatomically difficult to see.
