  Jaw Fracture: Urgent Dental Problems: Merck Manual Home Edition
Fractures of the upper jaw (maxilla) may cause double vision (because the muscles of the eye attach nearby), numbness in the skin below the eye (because of injuries to nerves), or an irregularity in the cheekbone that can be felt when running a finger along it.
The jaw may be held with a hand or preferably with a bandage wrapped under the jaw and over the top of the head several times (Barton's bandage).
Many jaw fractures can be repaired surgically with a plate (a piece of metal that is screwed into the bone on each side of the fracture); the jaws are immobilized for only a few days, after which soft foods can be eaten for several weeks.

  Jaw - Wikipedia, the free encyclopedia
The jaw is either of the two opposable structures forming, or near the entrance to, the mouth.
In vertebrates, the upper jaw or mandible is the mobile component that articulates at its posterior processes, or rami (singular ramus), with the temporal bones of the skull on either side; the word jaw used in the singular typically refers to the lower jaw.
The upper jaw or maxilla is more or less fixed with the skull and is composed of two bones, the maxillae, fused intimately at the median line by a suture; incomplete closure of this suture and surrounding structures may be involved in the malformation known as cleft palate.

 Phossy jaw - Wikipedia, the free encyclopedia
Phossy jaw is a deadly occupational hazard for those who work with white phosphorus in an environment without proper safeguards.
Over time, the jaw bone would begin to abscess, a process which was both extremely painful and disfiguring to the patient, and repellent to others, since drainage from the dying bone tissue was exceedingly foul-smelling.
Phossy jaw may occur as a side-effect of bisphosphonates, a class of phosphorus-based drugs that inhibit bone resorption, and are used widely for treating osteoporosis, bone disease in cancer and some other situations.

 Skeletal Jaw Deformities   (Site not responding. Last check: )
Jaw deformities may be defined as excesses and/or deficiencies in the transverse, horizontal, or vertical components.
A protrusive lower jaw is an obvious forward projection of the lower jaw or mandible beyond the upper jaw and beyond a normal distance from the cranial base due to horizontal mandibular excess.
The mandibular jaw deficiency syndrome can be classified as to Type I, II, or III with the classification being dependent upon the mandibular plane angle, which is either a steepening or a leveling of the lower jaw in relationship to a horizontal line.

 Jaw Wiring | AHealthyMe.com
Jaw wiring, also known as maxillomandibular fixation, is a surgical procedure where metal pins and wires are anchored into the jaw bones and surrounding tissues to keep the jaw from moving.
Wiring the jaws shut has been used in the past as a weight loss aid in cases of extreme obesity where other treatments had failed, although this procedure is rarely used for that purpose today.
Jaw wiring surgery can be performed by an oral or maxillofacial surgeon (a specially trained dentist), or by an otolaryngologist (a doctor specializing in surgeries of the head and neck).

Jaw fractures are the third most common type of facial fractures, after fractures of the nose and cheekbone.
In more than 50% of cases, the jaw fractures in at least two places — a "direct" fracture where the jaw was hit and an "indirect" fracture somewhere else along the jaw.
In teenagers and young adults, jaw fractures more commonly occur on the side of the face nearer the chin because this area is often struck during fights or attacks.

 ScienceDaily: Drug Used For Advanced Cancer Could Cause Exposed Bone In Jaw
The condition, called osteonecrosis of the jaw, is marked by exposed bone in the jaw and can lead to infection, inflammation and pain.
While researchers do not fully understand the condition or what causes it, osteonecrosis of the jaw, or ONJ, appears to occur in individuals who have been treated with drugs called bisphosphonates, which are used to improve bone strength.
When treating bone affected by cancer, the bisphosphonates are given intravenously and have been shown to decrease the risk of skeletal complications such as fracture.

 Jaw Disease Found in Patients Using Cancer Drug   (Site not responding. Last check: )
The discovery, published in the Journal of Oral and Maxillofacial Surgeons, prompted both the US Food and Drug Administration (FDA) and Novartis, the manufacturer of bisphosphonates used in cancer chemotherapy, to issue warnings earlier this fall to physicians and dentists about the risk for this potential adverse effect.
ONJ is a condition in which the bone tissue in the jaw fails to heal after minor trauma, such as a tooth extraction, causing the bone to be exposed.
In the FDA MedWatch and Novartis alerts issued in late September, oncologists and dentists were advised of the addition of osteonecrosis of the jaw to the “Precautions” and “Adverse Reactions” sections on the labeling of injectable bisphosphonates, describing the spontaneous reports of the condition being found mostly in cancer patients.
