Accuracy of fibular sectioning and insertion into a rapid-prototyped bone plate, for mandibular reconstruction using CAD-CAM technology

“…Modern techniques, such as CAD-CAM and rapid prototyping, offer new routes towards the planning of reconstructive maxillofacial surgery, allowing aesthetic outcomes to be optimised, and ensuring ultimate prosthetic and functional rehabilitation (Ciocca et al, 2009;Hou et al, 2012;Tarsitano et al, 2014). However, although many applications have been reported in the literature (Antony et al, 2011;Zhou et al, 2010;Markiewicz et al, 2011;Lethaus et al, 2012;Wang et al, 2013), no study to date has evaluated the accuracy of fibular cutting and insertion into a customized bone plate. In a previous article, Ciocca et al described restoration of mandibular anatomy after microvascular surgical reconstruction; the cited authors evaluated the positions of four anatomical reference points Mazzoni et al, 2013).…”

Costs incurred by applying computer-aided design/computer-aided manufacturing techniques for the reconstruction of maxillofacial defects

“…Today, CAD/CAM technology offers a reduction in the learning curve associated with osseous contouring, enhanced levels of accuracy, acceleration of the time-consuming intraoperative steps, improved esthetic contour, and improved functional outcome (Hou et al, 2011;Lethaus et al, 2011;Hayden et al, 2012;Levine et al, 2012;Foley et al, 2013). Various studies have revealed that application of the CAD/CAM technique eliminates the need for intraoperative measurement and yields bony segments with excellent apposition, achieves faithful duplication of the preoperative plan, and requires only minimal adjustments when the osseous transplant is inset (Marchetti et al, 2006;Hirsch et al, 2009;Antony et al, 2011). Furthermore, dental implant loading is possible at the time of osseous flap harvesting with a higher degree of accuracy than conventional techniques can provide.…”

A bar-retained overdenture as an external fixator device in a three-dimensional CAD/CAM-based surgical reconstruction of the mandible

“…The fixation of an implant drill guide requires auxiliary implants. As described by others (Antony et al, 2011;Freudlsperger et al, 2014;Roser et al, 2010;Schepers et al, 2013), 3D CAD/CAMsupported reconstruction of the mandible improves outcome and reduces surgery time. Considering that the fibula is harvested by a two-team approach in most circumstances, poor communication between the teams could lead to insufficient symmetry .…”
