Purpose:
To optimize reconstruction of maxillary unilateral defect by free fibula flap rapidly through 3D printing technique.
Methods:
3D models of reconstruction of unilateral maxillary defect by free fibula flap was established via CAD/CAM, metal customized plates and resin osteotomy guides were designed and manufactured via 3D printing technique, simulating operation was performed on models in vitro, and reconstructive accuracy after surgical simulation was analyzed using SPSS 18.0 software package.
Results:
Digital models involving reconstructive bone and affiliated devices (plates and guides) were established and fabricated rapidly. There was no significant difference between simulating point on computer and surgical simulating point in vitro.
Conclusions:
The optimized design and customized plate can increase the accuracy of reconstruction of maxillary defects with free fibula in vitro, which is helpful for accurate surgical reconstruction.
