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.
Patients may need post-orthodontic surgery, such as a fiberotomy or alternatively a gum lift, to prepare their teeth for retainer use and improve the gumline contours after the braces come off. After braces treatment, patients can use a transparent plate to keep the teeth in alignment for a certain period of time. After treatment, patients ...
Open bite treatment after eight months of braces. Other kinds of malocclusions can be due to or horizontal, vertical, or transverse skeletal discrepancies, including skeletal asymmetries. Increased vertical growth causes a long facial profile and commonly leads to an open bite malocclusion , while decreased vertical facial growth causes a short ...
Anterior open bite resulted from tongue thrusting in a 24 y.o. patient. Anterior upper teeth are not touching their counterpart. Anterior open bite (AOB) is defined as a condition in which there is no contact and no vertical overlap of the lower incisor crown with the upper incisor crown when the mandible is in full occlusion. [19]
The American Journal of Orthodontics was created for this purpose in 1915; before it, there were no scientific objectives to follow, nor any precise classification system and brackets that lacked features. [16] Until the mid-1970s, braces were made by wrapping metal around each tooth. [9]

Mandibular prognathism, where teeth have almost reached their final, straight position by dental braces, making the prognathism more obvious. In humans, non-pathological maxillary and alveolar prognathism can occur due to normal variation among phenotypes.
Measurement taken are as following: cleft palate (all or nothing), severe traumatic deviation (all or none), overjet (mm), overbite (mm), mandibular protrusion (mm), anterior open bite (mm), labiolingual spread (measurement of tooth displacement in mm) [9] [5] HLD index is used in several states in the United States, with some modifications to ...
