Resum

Introduction. Technological advances in preoperative planning and 3D printing allow custom-made biomedical devices to be synthesised using a completely digital workflow. The aim of this paper is to present and critically evaluate a new Orthognathic Positioning System (OPS) for Orthognathic Surgery. The OPS used bone-supported guides and a custom mini-plate to allow maxillary fragment positioning and fixation without the need for an inter-maxillary occlusal splint. Materials and methods. A prospective observational study was conducted on 10 cases of bimaxillary surgery using an inverse planning protocol. The guide and the custom-made mini-plate were designed using CAD-CAM software and synthesised by laser from commercially pure titanium powder. Accuracy was evaluated by overlap comparison of the virtual planning and 1-month postoperative CT scan. Operation times, complications, and overall safety profile were analysed. Results. The OPS was successfully applied to all cases, and was well tolerated. Operation times were reduced by avoiding inter-maxillary fixation, mini-plate bending, and obviating the need for intra-operative measurements. A mean postoperative accuracy of 1mm was obtained in 68.1% of cases. Conclusions. The positioning systems for orthognathic surgery that involve custom made systems of osteosynthesis, can be a future option that could increase accuracy and the safety of the procedure, as well as the surgical times. We believe this novel technology is a step forward in optimising and improving the delivery of orthognathic surgery care.
