CAD-CAM vs conventional technique for mandibular reconstruction with free fibula flap: A comparison of outcomes.

INTRODUCTION

Mandibular reconstruction always pose a challenge to the reconstructive surgeon. With the use of Computer aided designing and computer aided manufacturing (CAD-CAM) it is now possible to reconstruct mandibular defects to near normal configuration with good function and aesthetic outcomes.

AIMS/OBJECTIVES: To compare the efficacy of CAD-CAM technique vs conventional technique in mandibular reconstruction with free fibula flap.

MATERIALS AND METHODS

40 consecutive patients that required mandibular reconstruction using free fibula flap were included in the study. All patients were treated using CAD-CAM technique and then compared retrospectively with 40 patients treated with conventional technique. Comparison was done between total intraoperative time, aesthetic outcome and post-operative occlusion.

RESULTS

Total intraoperative time in the CAD-CAM group was significantly reduced (562 min) as compared to the conventional group (662 min). Patients in the CAD-CAM group also obtained a better Aesthetic score (3.6/5) when compared to the conventional group (2.5/5). Postoperative malocclusion was noted in 1 patient in the CAD-CAM group as opposed to 6 patients in the conventional group.

CONCLUSION

Use of CAD-CAM technology in mandibular reconstruction with free fibula flap offers reduced surgical time with precise and accurate reconstruction that produces better functional and aesthetic outcomes.
