A case of mandible osteonecrosis after a severe periimplant infection.

The term osteonecrosis has been applied to describe the presence of a persistent inflammation of the mouth, osteomyelitis, delayed healing of extraction sockets, development of sequestra or presence of fistulae from the mouth to the lower skin. Here, we document a case of mandible osteonecrosis that developed in a patient after a severe periimplant infection. Osteonecrosis, severe inflammatory osteolysis, and heavy bacterial colonization were found.

A rare case of rynopharyngeal melanoma.

Primary mucosal melanomas (MM) of the head and neck region constitute 0.5-2% of all malignant melanomas. The rynopharynx is a region that is less often involved by malignant melanomas.

A case report of haemorrhagic-aneurismal bone cyst of the mandible.

Haemorrhagic-aneurismal bone cysts (HABCs) are quite rare, benign, non-neoplastic, expansive, and vascular locally destructive lesions. They are generally considered sequelae of an earlier trauma causing an overflow of blood into the bone. HABCs are classified as pseudocysts and they should be differentiated from true cysts because their treatment is different.

Implant rehabilitation in grafted and native bone in patients affected by ectodermal dysplasia: evaluation of 78 implants inserted in 8 patients.

Objectives: Ectodermal dysplasia (ED) is a congenital syndrome characterized chiefly by abnormalities of tissues of ectodermal origin, namely skin, nails, hair, and teeth. Dental treatment of patients with ED is necessary, because it affords the opportunity to develop normal forms of speech, chewing, swallowing, and normal facial support. Because there are few reports focusing on implants inserted in bone grafted in patients affected by ED.
