[Reconstruction of the mandible after loss of the middle segment due to an odontogenic myxoma].

In an 18-year-old boy, the middle segment of the mandible was removed because of a locally aggressive tumour. The reconstruction became infected and was lost, resulting in 2 separately-moving mandible parts and oral disability. For the second reconstruction, skeletal fixation with osteosynthesis plates, dental fixation with a stabilization frame and intermaxillary fixation were used. Preparation for returning the jaws to their original position was facilitated by three-dimensional simulation software. After a successful second reconstruction, an implant-supported removable bridge was eventually placed.
