Abstract

Background: 

The recent increase in computer-aided design and computer-aided manufacturing (CAD/CAM)-assisted surgery has warranted a thorough evaluation of the accuracy of virtual plan execution. Mandibular reconstructions with a fibula free flap were evaluated by comparing the fibular segments postoperatively with the virtual surgical plans.

Methods: 

This study included computed tomography data for 20 patients (11 males; mean age 61.3 years, range 47–74) that received a mandibular reconstruction with a fibula free flap. Linear distances (superior and inferior borders) of 41 fibula segments and intercoronoid distances were measured.

Results: 

The mean difference was 3.11 ± 2.80 mm for superior borders (range 0.02–12.20 mm), and 2.75 ± 2.61 mm for inferior borders (range 0.22–13.58 mm). The mean intercoronoid difference was 3.57 ± 1.80 mm (range 0.91–6.11 mm).

Conclusion: 

This study confirmed the presumed accuracy regarding the use of fibular and mandibular cutting guides. CAD/CAM is an attractive technique which enhances efficiency and assurance during surgery and preoperative planning.
