3D Printed Occlusal Splints for Intraoperative Use

Treatment of dentofacial deformities requires restoration of occlusion. Occlusal splints stabilize the jaws intraoperatively to restore occlusion, which improve functions such as mastication, speech, breathing, and appearance. Orthodontic resins and denture material have been used to fabricate dental splints due to the biocompatibility nature and ease of use. These materials, throughout the years, have been found to have structural stability, used for various purposes including nightguards, occlusal splints, etc. In recent years with the advanced of computer automated design (CAD/CAM), these splints have been outsourced to industry manufacturers. Industry-made printed splints are costly and time-consuming, highlighting the need for faster, more affordable solutions. In-house printed splints have demonstrated consistent uniformity with negligible differences in shape to the source files. The investigators hypothesize that in-house printed models will be at least as effective as industry-made models in the application of acute craniofacial trauma while decreasing costs and production time. This study evaluates the feasibility and benefits of in-house 3D printed occlusal splints. By using the same printers and biocompatible resin as industry manufacturers12, in-house splints maintain patient safety, while reducing hospital stay durations, lowering infection rates, and increasing hospital turnover. This approach could improve surgical efficiency and patient outcomes, offering a cost-effective alternative in mandibular surgery.
