Preoperative Assessment for Surgical Accuracy in Maxillofacial Surgery Cases Using Stereolithographic Models

Abstract

Recent advancements in imaging technologies, particularly stereolithography, have transformed medical and surgical practices, including oral and maxillofacial surgery. Utilizing precise three-dimensional (3D) models crafted from virtual representations, these innovations have revolutionized diagnosis, treatment planning, and surgical simulation. In a study conducted at the Department of Oral and Maxillofacial Surgery, Sri Ramaswamy Memorial (SRM) Dental College, Chennai, five patients with complex maxillofacial deformities underwent surgical interventions guided by stereolithographic models. Despite challenges such as fabrication time and cost constraints, the integration of 3D models significantly streamlined preoperative planning, reduced operative time, and facilitated precise surgical execution. Customized implants and pre-bent plates, based on model simulations, enabled conservative surgical approaches and optimal fit and function. The integration of stereolithography with computer-aided design/computer-aided manufacturing (CAD/CAM) software represents a significant advancement in enhancing surgical precision and improving patient outcomes in cranio-maxillofacial surgery.
