Functional Rehabilitation of Mandibular Continuity Defects Using Autologous Bone and Dental Implants – Prognostic Value of Bone Origin, Radiation Therapy and Implant Dimensions

Aim: The aim of this retrospective study was to investigate prognostic parameters for the rehabilitation of mandibular continuity defects with free autologous bone and dental implants for patients after intraoral squamous cell carcinoma. Methods: Following potential prognostic factors for implant su...
