About

Open bite is a common dentoalveolar component of the facial pattern of the excessive vertical dimension patients that is also known as the gaping angle face pattern.It is a deformation in the vertical relationship between the upper and the lower dental arches that is characterized by the loss of contact between the opposite dental segments.

Full description

An open bite develops as a result of the interaction of many etiologic factors, both hereditary and environmental. Prolonged sucking habits and hyper-divergent facial characteristics are significant risk factors for an anterior open bite in the mixed dentition. Abnormal tongue posture (frequently associated with enlarged adenoids or tonsils) and tongue thrust also can be involved in the establishment of alveolar and skeletal discrepancies concurrent with vertical problems Two types of an open bite are recognized in this profession: (1) dentoalveolar open bite: the abnormality formalities aspects limiting in the dental and alveolar region, usually associated with abnormal function habits as the thumb sucking and (2) Skeletal open bite: that's associated with an over high of the lower facial vertical dimension and a large plane angle of the lower jaw. open bites associated with excessive vertical skeletal dimensions are difficult to treat and tend to relapse The investigators must be recognized between the dentoalveolar open bite and the open bite caused by formalities disorders and the position disorders of the upper or the lower jaw or both. Dental an open bite can be corrected by itself if the treatment was beginning early and it's responding Easley to the mechanical treatment methods and the functional treatment approaches that depending on the muscular activity
