Abstract
Mandibular distraction osteogenesis (MDO) is a fairly common procedure in specialized craniofacial surgery centers. The MDO is a minimally invasive technique that is able to generate new bone in patients with a severe hypoplastic ascending ramus, while also expanding the overlying soft tissues; therefore, it has become the treatment of choice for the surgical correction of mandibular hypoplasias. One of the most common postoperative complications involves misplacement of the distractor and/or corticotomy, which can result in the creation of an erroneous distraction vector. The introduction of 3-dimensional (3D) printing has revolutionized preoperative planning in several surgical fields; however, cost can hinder its application in developing nations, specially in public institutions. The aim of this work is present our experience using low-cost 3D-printed anatomic models for preoperative planning and surgical simulation in patients requiring MDO.
