Osteonecrosis of the jaw (ONJ) is a severe bone disease (osteonecrosis) that affects the jaws (the maxilla and the mandible).Various forms of ONJ have been described since 1861, and a number of causes have been suggested in the literature.
The bones of the jaws seem to have some evolutionary resistance to this process. When bone is exposed at other sites in the human body, this is a much more serious condition. In a dry socket, healing is delayed because tissue must grow from the surrounding gingival mucosa, which takes longer than the normal organisation of a blood clot.
Exposed and necrotic bone or a fistula that probes to bone in patients with pain, infection, and one or more of the following: exposed and necrotic bone extending beyond the region of alveolar bone,(i.e., inferior border and ramus in the mandible, maxillary sinus and zygoma in the maxilla) resulting in pathologic fracture, extra-oral fistula ...
The presence of buccal exostosis can be diagnosed by both clinical examination and radiological interpretation of the oral cavity. Clinically, buccal exostoses appear as single, broad-based masses, usually situated bilaterally in the premolar and molar region on the facial surface of the maxillary alveolar bone. [11]
OM may occur by direct inoculation of pathogens into the bone (through surgery or injury), by spread of an adjacent area of infection or by seeding of the infection from a non adjacent site via the blood supply (hematogenous spread). Unlike OM of the long bones, hematogenous OM in the bones of the jaws is rare. OM of the jaws is mainly caused ...
Jaw pain Stress and grinding your teeth at night are both generally benign reasons behind why your jaw may be aching. But persistent jaw pain may also be a sign of an underlying health condition.
More likely, [50] alveolar osteitis is a phenomenon of painful inflammation within the empty tooth socket because of the relatively poor blood supply to this area of the mandible (which explains why dry-socket is usually not experienced in other parts of the jaw). Inflamed alveolar bone, unprotected and exposed to the oral environment after ...
Orthognathic surgery (/ ˌ ɔːr θ ə ɡ ˈ n æ θ ɪ k /), also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and lower face related to structure, growth, airway issues including sleep apnea, TMJ disorders, malocclusion problems primarily arising from skeletal disharmonies, and other orthodontic dental bite problems that cannot ...
