Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* Investigate the accuracy of inserting implants in the anteroposterior way, in the vertical way and in angulation for all the involved patients (meaning on irradiated native mandible or on microanastomosed fibula flaps)
* Investigate the delay of mucous healing
* Estimate the prosthetic function
* Evaluate the osteonecrosis rate after radiation with traumatic etiology due to implantation
* Estimate the implant rate due to minimally invasive flaps
* Estimate the implant rate due to pure trans mucosa way
* Estimate the post surgical therapeutic success after 1 year

Therapeutic assessment -Radio-surgical guidance.
The first steps of the procedure include the production of a radiosurgical guide and the preparation of a mask in order to allow precise, non invasive repositioning of the guide.
Secondarily, the patient undergoes a CT-scan with the mask on and the radiosurgical guide in place. This provisional scan is used for preimplantation evaluation and drilling of the guide hole.
Under general anaesthesia, the mask is placed on the patient and the guide is fixed to the mask. A hole is drilled with a burr in the mandible through the hole in the guide. Implants are placed and the guide and mask are removed.
A second, post-implantation CT-scan is planned 3 months after implantation. Comparison of pre- and post-implantation CT-scans allows to evaluate the precision of the placement.
