[Technologies for resection and reconstruction of mandibular lesions].

Restoring the bony structure of the face is a significant challenge. Due to the complex three dimensional anatomy, the presence of critical structures and the variety and uniqueness of each deficiency it is essential to form the optimal surgical plan and to execute it precisely. Development of computer aided manufacturing (CAD/CAM - computer assisted design / computer assisted manufacturing) and advances in manufacturing technologies and material science brought a whole array of options and tools for the purpose of planning and performing computer assisted surgery. CAD / CAM technology allow for various application: Manufacturing of custom made implants. The surgeon may choose which of the application to use in any specific case or combine all of these abilities according to the complexity of the case. Two cases presenting the applications of these technologies will be reviewed.
