Type of Deepbite in Orthodontic Treated Patients

Abstract

Deep bite is a common malocclusion that can occur in both children and adults. It is defined as an excessive vertical overlap of the upper teeth on the labial surface of the lower teeth when the teeth are in centric occlusion. Deep bite can be classified according to its origin (dental or skeletal), function (true or pseudo), and extent (incomplete or complete). The aetiological factors of deep bite include inherent factors (tooth morphology, skeletal pattern, and malocclusion) and acquired factors (muscular habit, change in tooth position, loss of posterior supporting tooth, and lateral tongue thrusting habit). Deep bite is more common in some racial groupings than others, and it is associated with compromising periodontal health of maxillary anteriors and the palatal tissue. This study found that 58% of orthodontic patients had deep bite, and 71% of those had incomplete deep bite. Females were more likely to have deep bite than males.
