Oral cavity cancer involving lower jaw (mandible) is common . After excision of involved part of mandible , its reconstruction is must to facilitate normal function of remaining mandible (proper relation of teeth of upper and lower jaw) and to achieve normal aesthetic appearance of face.
The best bone to reconstruct mandible is fibula, but it is straight and mandible is convex angulated at places. To achieve shape of mandible , we have to do osteotomies in fibula .
To know exact site and number of osteotomies required, 3D printing models are of great help. By doing virtual surgeries on 3D models, we come to know exact site and number of osteotomies required in fibula to achieve normal function and shape of reconstructed mandible.
