The anatomical frontal portion of the mandible, also known as the mentum, that contains the line of fusion of the two separate halves of the mandible (symphysis menti). This line of fusion divides inferiorly to enclose a triangular area called the mental protuberance. On each side, inferior to the second premolar tooth, is the mental foramen for the passage of blood vessels and a nerve.
The largest and strongest bone of the FACE constituting the lower jaw. It supports the lower teeth.
Congenital or acquired asymmetry of the face.
Orthognathic Surgical Procedures
A condition marked by abnormal protrusion of the mandible. (Dorland, 27th ed)
Malocclusion, Angle Class III
Malocclusion in which the mandible is anterior to the maxilla as reflected by the first relationship of the first permanent molar (mesioclusion).
The length of the face determined by the distance of separation of jaws. Occlusal vertical dimension (OVD or VDO) or contact vertical dimension is the lower face height with the teeth in centric occlusion. Rest vertical dimension (VDR) is the lower face height measured from a chin point to a point just below the nose, with the mandible in rest position. (From Jablonski, Dictionary of Dentistry, 1992, p250)
Medicine, East Asian Traditional
The posterior process on the ramus of the mandible composed of two parts: a superior part, the articular portion, and an inferior part, the condylar neck.
Feeding and Eating Disorders of Childhood
The process of growth and differentiation of the jaws and face.
Orthodontic Appliances, Functional
Loose, usually removable intra-oral devices which alter the muscle forces against the teeth and craniofacial skeleton. These are dynamic appliances which depend on altered neuromuscular action to effect bony growth and occlusal development. They are usually used in mixed dentition to treat pediatric malocclusions. (ADA, 1992)
Extraoral Traction Appliances
Orthodontic Appliances, Removable
A mobile U-shaped bone that lies in the anterior part of the neck at the level of the third CERVICAL VERTEBRAE. The hyoid bone is suspended from the processes of the TEMPORAL BONES by ligaments, and is firmly bound to the THYROID CARTILAGE by muscles.
The thickest and spongiest part of the maxilla and mandible hollowed out into deep cavities for the teeth.
