Osteointegration in oncologic patients: a case report.

Objective: the present case report aims at illustrating how implant-prosthetic rehabilitation in patients with oral cancer resection aids to improve their quality of life.

Material And Methods: a patient with verrucous squamous cell carcinoma of the mandible was treated with surgery and rehabilitation with three interforaminal dental implants and Toronto bridge. Three years after treatment, because of cancer recurrence, a segment of jaw and one of the three mandibular implants were removed.

Case control study to assess the possibility of decrease the risk of osteoradionecrosis in relation to the dose of radiation absorbed by the jaw.

Aims: the assessment of the limit dose for the organs at risk in external radiotherapy is a fundamental step to guarantee an optimal risk-benefit ratio. The aim of this study was to assess, through contouring the single dental cavities, the absorbed radiation dose on irradiated alveolar bones during the treatment of cervico-facial tumours, so as to test the correlation between the absorbed dose of radiation at alveolar level and the level of individual surgical risk for osteonecrosis.

Materials And Methods: we selected 45 out of 89 patients on the basis of different exclusion criteria.
