A jaw abnormality is a disorder in the formation, shape and/or size of the jaw. In general abnormalities arise within the jaw when there is a disturbance or fault in the fusion of the mandibular processes. The mandible in particular has the most differential typical growth anomalies than any other bone in the human skeleton.
Long face syndrome, also referred to as skeletal open bite, [1] is a relatively common condition characterised by excessive vertical facial development. [2] Its causes may be either genetic or environmental. Long face syndrome is "a common dentofacial abnormality." [3]: 369 [4] Its diagnosis, symptomology and treatments are complex and ...
Corrective surgery is the most common treatment to correct this disorder. It involves the repositioning of the upper jaw to align with the lower jaw, to provide symmetry. The surgery may be performed in consultation with an Orthodontist who works on repositioning the teeth in the mouth. [1]
It is estimated that nearly 30% of the general population present with malocclusions that are in great need of orthodontic treatment. [1] However, the term dentofacial deformity describes an array of dental and maxillo-mandibular abnormalities, often presenting with a malocclusion, which is not amenable to orthodontic treatment alone and definitive treatment needs surgical alignment of upper ...
Micrognathism is a condition where the jaw is undersized. It is also sometimes called mandibular hypoplasia. [2] It is common in infants, [3] [4] but is usually self-corrected during growth, due to the jaws' increasing in size. It may be a cause of abnormal tooth alignment and in severe cases can hamper feeding. [5]
Craniofacial abnormalities are congenital musculoskeletal disorders which primarily affect the cranium and facial bones. [ 1 ] They are associated with the development of the pharyngeal arches . [ 2 ]
An intact prehistoric mastodon jaw was discovered in the backyard of a Hudson Valley house after the homeowner initially saw a pair of teeth poking up by a plant, according to state officials.
Overbite is the extent of vertical (superior-inferior) overlap of the maxillary central incisors over the mandibular central incisors, [1] measured relative to the incisal ridges. [2] The term overbite does not refer to a specific condition, nor is it a form of malocclusion. Rather an absent or excess overbite would be a malocclusion.
