Personalized Occlusal Guide Guides Panfacial Fracture Repair and Reconstruction.

Restoration of the occlusal relationship is the key point in the treatment of maxillofacial fractures. Poor restoration of the occlusal relationship seriously impacts oral function as well as physical and mental health. This study combines virtual surgical technology with model surgery, uses computed tomography data to establish a maxillofacial bone model, and performs a virtual reduction of fractures. The upper and lower dentition models after reconstruction were intercepted and 3-dimensional printed. After the occlusal relationship was reconstructed by the prosthodontist using the model, an occlusal reduction guide was designed and manufactured based on the reconstructed occlusal relationship to accurately reduce the occlusal relationship in patients with maxillofacial fractures. This study proposes an occlusal guide design process for maxillofacial fractures and optimizes the traditional model surgical process to provide a convenient surgical strategy. This study provides new ideas for the design of personalized surgical guides for maxillofacial fractures.
