Abstract

Introduction: The introduction of CAD/CAM technology in orthognathic surgery planning has facilitated the procedure and allowed for more predicted results. This study was designed to introduce and evaluate the clinical use of a CAD/CAM surgical guide for bilateral sagittal split osteotomy (BSSO) in the correction of dentofacial deformity cases with skeletal class 2 or 3.
Aim of the study: To evaluate the efficiency of guided osteotomy in orthognathic surgery. Materials and Methods: This study was made on twenty patients who will undergo bilateral sagittal osteotomy procedure. Ten of them (group A) (control group) was treated via a conventional method without an osteotomy guide while the other ten patients (group B) (the study group) via a CAD/CAM bone-borne guide. Postoperative patient evaluation was performed clinically by comparing the operation time and sensory nerve involvement (1w, 2ws, 3 months) and radiographically by CT at 1 month postoperatively.
Results: The surgical outcome revealed the satisfactory correction of their skeletal deformity. The study group showed significantly better results than control group concerning operation time, Visual Analogue Scale, and sensory nerve involvement (p ≤ 0.05.)
Conclusion: Within the limitations of this study, it can be considered that CAD/CAM osteotomy guide for BSSO is superior to non-guided BSSO regarding the operation time and sensory nerve involvement.
