Introduction: Bone reconstruction using a ramus graft is a critical procedure for patients with limited bone availability for dental implant placement. Traditional methods often face challenges related to precision and the fit of the graft, which can affect the overall success of the surgery. The advent of Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) technology has introduced new possibilities for improving the planning and execution of these procedures. This study aims to evaluate the benefits of CAD/CAM in enhancing the precision, efficiency, and outcomes of surgical ramus grafts.
Methods: This study involved a cohort of patients requiring ramus grafts for bone augmentation prior to dental implant placement. CAD/CAM technology was used for the preoperative digital evaluation of donor and recipient sites, allowing for precise planning of graft dimensions. Custom surgical guides were created using CAD/CAM to assist in the accurate harvesting of the grafts. Intraoperative performance, graft fit, and postoperative outcomes, were assessed and compared with outcomes from traditional surgical methods.
Results: The preliminary findings of this study demonstrate that the use of CAD/CAM technology significantly enhanced both the preoperative planning and intraoperative execution of ramus graft procedures. Through digital modeling, tailored graft designs were achieved, which matched the specific anatomical requirements of each patient. This resulted in a reduced intraoperative time and a more precise fit of the graft. Early postoperative assessments indicate fewer complications, such as damage to the inferior alveolar nerve, and improved healing outcomes when compared to traditional methods.
Conclusion: CAD/CAM technology offers substantial benefits in the planning and performance of surgical ramus grafts for bone reconstruction. By enhancing precision and reducing intraoperative risks, CAD/CAM contributes to more predictable and successful outcomes, making it a valuable tool in complex dental implant procedures. While CAD/CAM technology currently involves higher initial costs, practitioners are encouraged to consider the advantages of CAD/CAM, as its adoption can lead to improved patient outcomes and a higher standard of care.
