“…Especially, achieving the proper alignment/parallelism of the transcutaneous pins, EDI placement and accurate osteotomy are very difficult (Guruprasad and Hemavathy, 2012). Inaccuracy in the procedure results malocclusion (Behnia et al , 2013; Şençimen et al , 2014). Imprecise placement of pins results: tooth injury, damage to adjacent vital structures, inappropriate distraction vector and pin loosening (Neelakandan and Bhargava, 2012; Rachmiel et al , 2014).…”

Purpose The purpose of this paper is to develop a workflow for design and fabrication of customized surgical guides (CSGs) for placement of the bidirectional extraoral distraction instruments (EDIs) in bilateral mandibular distraction osteogenesis (MDO) surgery to treat the bilateral temporomandibular joint ankylosis with zero mouth opening. Design/methodology/approach The comprehensive workflow consists of six steps: medical imaging; virtual surgical planning (VSP); computer aided design; rapid prototyping (RP); functional testing of CSGs and mock surgery; and clinical application. Fused deposition modeling, an RP process was used to fabricate CSGs in acrylonitrile butadiene styrene material. Finally, mandibular reconstruction with MDO was performed successfully using RP-assisted CSGs. Findings Design and development of CSGs prior to the actual MDO surgery improves accuracy, reduces operation time and decreases patient morbidity, hence improving the quality of surgery. Manufacturing of CSG is easy using RP to transfer VSP into the actual surgery. Originality/value This study describes an RP-assisted CSGs fabrication for exact finding of both; osteotomy site and drilling location to fix EDI’s pins accurately in the mandible; for accurate osteotomy and placement of the bidirectional EDIs in MDO surgery to achieve accurate distraction.
