Chin: 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.Mandible: The largest and strongest bone of the FACE constituting the lower jaw. It supports the lower teeth.Skin Cream: A water-soluble medicinal preparation applied to the skin.Facial Asymmetry: Congenital or acquired asymmetry of the face.Orthognathic Surgical Procedures: Surgery performed to repair or correct the skeletal anomalies of the jaw and its associated dental and facial structures (e.g. CLEFT PALATE).Cephalometry: The measurement of the dimensions of the HEAD.Prognathism: A condition marked by abnormal protrusion of the mandible. (Dorland, 27th ed)Dermatitis, Irritant: A non-allergic contact dermatitis caused by prolonged exposure to irritants and not explained by delayed hypersensitivity mechanisms.Hypesthesia: Absent or reduced sensitivity to cutaneous stimulation.Desonide: A nonfluorinated corticosteroid anti-inflammatory agent used topically for DERMATOSES.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).Vertical Dimension: 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)Face: The anterior portion of the head that includes the skin, muscles, and structures of the forehead, eyes, nose, mouth, cheeks, and jaw.Medicine, East Asian Traditional: Medical practice or discipline that is based on the knowledge, cultures, and beliefs of the people in EAST ASIA.Mandibular Condyle: 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.Micrognathism: Abnormally small jaw.Feeding and Eating Disorders of Childhood: Mental disorders related to feeding and eating usually diagnosed in infancy or early childhood.Maxillofacial Development: 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)Lip: Either of the two fleshy, full-blooded margins of the mouth.Extraoral Traction Appliances: Extraoral devices for applying force to the dentition in order to avoid some of the problems in anchorage control met with in intermaxillary traction and to apply force in directions not otherwise possible.Orthodontic Appliances, Removable: Dental devices such as RETAINERS, ORTHODONTIC used to improve gaps in teeth and structure of the jaws. These devices can be removed and reinserted at will.Beauty: Characteristics or attributes of persons or things which elicit pleasurable feelings.Orthodontic Extrusion: Orthodontic movement in the coronal direction achieved by outward tension on the PERIODONTAL LIGAMENT. It does not include the operative procedure that CROWN LENGTHENING involves.
