Surgical Planning for Mandibular Distraction Osteogenesis Using Low-Cost Three-Dimensional–Printed Anatomic Models

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.

3D Printing Applications for Craniomaxillofacial Reconstruction: A Sweeping Review

“…The broad scope of anatomical model applications in oncologic, traumatic, and congenital CMF reconstruction is described in Table . Within this subset of representative cases, SLA − and FDM ,,, were the most commonly employed AM techniques. Models were studied both preoperatively and intraoperatively for surgery simulation and resident training, patient education, situating hardware and/or implant placement, and bending off-the-shelf fixation devices to anatomical contours.…”
