Osteoradionecrosis Osteoradionecrosis (ORN) of the jaw is a significant complication of radiotherapy for oral cavity cancer. In addition to antibiotic medication, treatment options such as hyperbaric oxygen therapy, surgical approaches, and combined therapy with pentoxifylline and tocopherol have been recently introduced.

- Definition and cause. Osteomalacia is a state of depletion of calcium from the body's bones due to lack of vitamin D. Vitamin D enables the body to absorb calcium and phosphate from the gut while limiting the elimination of calcium in the urine and thus maintain an adequate calcium level in the body.steomalacia can thus occur in the absence of intake of vitamin D e.g. in diseases of malabsorption, where the uptake from the intestine is impaired or in lack of sunlight, for example as seen in some Muslim women, who are completely covered.

Mandibular Dislocation What is a mandibular dislocation? A mandibular dislocation is the separation of your mandible (lower jaw) from your temporomandibular joint (TMJ). When this happens, your lower jaw does not go back in place on its own. What causes a mandibular dislocation? Opening your mouth too wide: This may happen when you laugh, yawn, sneeze, take large bites, or vomit. Some open mouth or dental procedures may weaken the muscles around your TMJ and lead to dislocation. Tooth problems: Teeth that are missing, worn, or not lined up correctly can prevent your jaw from working correctly.

- From Wikipedia, the free encyclopedia. A buccal exostosis (also termed alveolar exostosis), is an exostosis (bone prominence) on the buccal surface (cheek side) of the alveolar ridge of the maxilla or mandible. Some consider them a variation of normal anatomy rather than a disease.rom Wikipedia, the free encyclopedia.

- ONJ consists of non-healing avascular necrosis in the mandible or maxilla (Morris & Cruickshank, 2006). Kienbock disease is avascular necrosis of the scaphoid bone. Soon afterwards he had a double hip replacement because of avascular necrosis, a condition where the blood supply to the bones dries up.

- Torus mandibularis (pl. tori mandibulares) (or mandibular torus (pl. mandibular tori) in English) is a bony growth in the mandible along the surface nearest to the tongue. Mandibular tori are usually present near the premolars and above the location of the mylohyoid muscle 's attachment to the mandible.

What Is the Mandibular Ramus? The mandibular ramus is a portion of the mandible, or jawbone. As the bone that stretches from the underside of either ear and gives rise to the bottom teeth, the mandible consists of the body, which is the horizontal portion crossing the chin, and the ramus, the vertical section beneath each ear.he mandible is the lower part of the jaw, which moves like a hinge thanks to a network of muscles. The mandibular ramus serves as the bridge attaching the jaw to the temporal bone of the skull via the temporomandibular (TMJ) joint. View slideshow of images above. Watch the Did-You-Know slideshow.

What is the Mandible? Vertical extensions of the mandible form left and right joints with the main portion of the skull, the cranium, to form the jawbone joints. The name for these joints is the tempero mandibular joints. In mandible anatomy, names are given to various parts of the jawbone. The main names for the different parts of the mandible are the body, the condoyle, the coronoid process, and the ascending ramus. The body is the middle part of the bone that forms a U-shape and holds the lower teeth.

- The mandible has names for its different parts, as follows: 1  The body of the mandible is the middle section of the U-shape which supports the lower teeth. 2  The condyle is the rounded end of bone that fits into the movable joint between the mandible and the cranium (the part of the skull which encloses the brain).OWER JAW (MANDIBLE). The lower jaw has its own separate bone which is called 'the mandible', which is U-shaped and stretches from one ear, down to the chin area and then back up again to the other ear.

Osteoradionecrosis Osteoradionecrosis usually occurs in the mandible, and causes chronic pain and surface ulceration. Prevention of osteradionecrosis is part of the reason all teeth of questionable prognosis are removed before the start of a course of radiotherapy. Osteoradionecrosis of the jaw is a significant complication of radiotherapy for oral cavity cancer. In addition to antibiotic medication, treatment options such as hyperbaric oxygen therapy, surgical approaches, and combined therapy with pentoxifylline and tocopherol have been introduced.

Jaw Claudication Jaw claudication is associated with some serious underlying diseases. The onset of jaw claudication generates pain in the maxilla and mandible bone during mastication which may extend up to ear. It is a symptomatic approach, but not a disease. In medical science, the jaw claudication is considered as a diagnostic aspect as it is not a common symptom and associated with some specific disorders. It occurs due to occlusion of the carotid artery.

Mandible The mandible, or lower jaw, is the bone that forms the lower part of the skull, and along with the maxilla (upper jaw), forms the mouth structure. Movement of the lower jaw opens and closes the mouth and also allows for the chewing of food. The lower set of teeth in the mouth is rooted in the lower jaw.
