Customization of Patient Specific Distraction Device using Additive Manufacture Technology

Abstract

Additive Manufacturing (AM) technology is an engineering technology which has a wide scope in medical field. Individual planning of complex maxillofacial surgical procedures require 3D models for the precise outcome and reduction in the surgical time and thereby complications. AM technology can be used for the manufacture of patient specific models using Computed Tomographic (CT) Scan data for the complex surgical procedures. Design method for personalized Mandibular Transport Distraction device manufacturing by using medical Additive Manufacturing (AM) is presented in this paper. The present work explains the use of AM models for planning of a case of mandibular defect secondary to tumour ablation. The surgical method used to correct the deformity is called Distraction Osteogenesis (DO). It involves new bone formation between fractured bony segments which are separated by gradual, controlled incremental traction. This results in simultaneous expansion of soft tissue and bone volume. The Transport DO procedure of mandible involves creation of a transport segment which is separated from the residual bone to be distracted to the other side of the bone present. The outcome depends on an important principle called as Distraction Vector where the direction and magnitude dictates the outcome. The use of Additive Manufactured models made to plan the Distraction vector precisely and made the operation easier and more accurate. Moreover preoperative preparation reduced the operating time.© 2017 Elsevier Ltd.
