Study group
OSCC
This cross-sectional study investigated donor-site morbidity of patients who received a CAD/CAM driven DCIA graft reconstruction of the mandible following resection of OSCC in our single tertiary center (Clinic of Oral and Maxillofacial Surgery, Medical Center— University of Freiburg, Germany). Patients who underwent CAD/CAM driven DCIA graft reconstruction of the mandible were identified by thorough review of all electronic patient charts of our clinic and were invited for physical follow-up examination. At the time of study conception, CAD/CAM was already introduced as standard operating procedure for bony reconstruction after ablation of OSCC at our clinic. Conventional operations were only performed in exceptional cases and could therefore not be investigated as a control group.
