TRIAL DESCRIPTION
Public title Computer-guided mandibular segmental resection and immediate reconstruction using patient specific titanium devices versus conventional techniques: R
Official scientific title Computer-guided mandibular segmental resection and immediate reconstruction using patient specific titanium devices versus conventional techniques: Randomized Control clinical trial.
Brief summary describing the background
and objectives of the trial
The rehabilitation of patients affected by defects of the mandible after tumor resection is still very challenging. Resection can lead to significant facial deformity, impaired oral functions such as speech, swallowing, saliva retention, and concomitant psychological problems. Moreover, the loss of teeth and the alveolar and basal jaw bone can lead to significant impairment of mastication. There are different methods of reconstruction of such defects. Autogenous bone grafts or revascularized fr
