Central osteoma of the maxilla: implant rehabilitation with immediate loading in fresh extraction socket.

Aim Of The Study: Solitary central osteomas of the jaw seem to be especially rare lesions; since 1955, only 12 cases have been reported and 4 of these were located in the maxilla. Osteomas are benign osteogenic lesions considered as real tumours but without infiltrative or metastatic potential. Their growth potential is usually limited, but certain rare and large cases of peripheral osteoma are described in literature.

Implant-supported prostheses with temporomandibular joint reproduction after hemimandibular resection: a case report.

Aim Of The Study: The change in anatomy and physiology resulting from radical mandible surgery is often exacerbated by radiation therapies that make the mucosa atrophic and susceptible to irritation and ulceration rendering the task of areating functional complete dentures for edentulous subjects very challenging to prosthodontists. The aim of this study is to describe an implant supported denture rehabilitation in an edentulous hemimandibulectomized patient with a singular prosthetic design in order to compensate for the lack of a condylar process.

Materials And Methods: The subject of the clinical case, had a history of squamous cell carcinoma of the right tonsillar region for which it was subjected to a hemimandibulectomy and was primarily rehabilitated with an over denture mounted onto a bar furnished by a resin condylar eminence in articulation with the glenoid fossa of the upper denture.

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.

Multiple systemic diseases complicated by bisphosphonate osteonecrosis: a case report.

Aims: this work aims at demonstrating that multiple systemic conditions, in association with the development of bisphosphonate associated osteonecrosis of the jaw (ONJ), increase the risk of complications and may lead to hospitalization. For this reason the dental approach to patients with multisystem disease should be carefully managed by a team of specialists.

Case Report: a case of mandibular necrosis associated with intake of oral bisphosphonates in a complex systemic context is described.

Implant-supported denture rehabilitation on a hemimandibulectomized patient: a case report.

Aim Of The Study: the treatment of oral cancer requires different surgical approaches such as marginal or segmental mandibular resection in order to allow a safe removal of the neoplastic lesion. The aim of this work is to evaluate the efficacy of an implant-supported denture rehabilitation for restoring oral function and facial appearance on a hemimandibulectomized patient.

Materials And Methods: the patient was a 64 years old man, hard smoker and moderate drinker.

Implant-supported rehabilitation of a patient with mandibular ameloblastoma.

Objectives: this report describes the masticatory implant- supported rehabilitation of a patient undergoing resection for mandibular ameloblastoma.

Case Report: in the reported case the patient underwent resection and reconstruction with a fibula flap for masticatory rehabilitation of 7 implants at the level of the mandible.

Discussion: ameloblastoma is a benign locally invasive tumor of maxillary bones that often causes facial disfigurement.

Implant rehabilitation in patients irradiated for head and neck cancer: role of Intensity-Moduled Radiotherapy (IMRT) in planning the insertion site.

Purpose: currently, head and neck irradiation is not considered an absolute contraindication for implant placement (1), especially due to the transition from conventional to conformal radiotherapy. However, there is a difference in the success rate of implant placement between irradiated and non-irradiated bones (5). Successful osseointegration is mainly affected by the total dose of radiation (6).

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.
