Common Concerns

Class II

Class II problems represent abnormal bite relationships in which the upper jaw and teeth project ahead of the lower jaw (overjet), and the molars do not fit together properly.  Often this is a result of insufficient growth of the lower jaw.

Class III

Class III problems are when the lower jaw and teeth are displaced to the front of the upper jaw structure and the molars do not fit together properly.  Facially, the appearance may give the impression that the lower jaw is excessively large, but in many cases the lack of upper jaw development is at fault.

Crossbite

Posterior crossbites usually result from a constricted upper jaw or unusually wide lower jaw.  A narrow upper jaw will often force a patient to move their lower jaw forward or to the side when closing into a stable bite.  When closed into this accommodated position, the lower teeth are located outside the upper teeth.  This posturing may result in an incorrect functional position of the lower jaw with accompanying facial asymmetry.

Crowding

Crowding of teeth is the most common problem associated with the need for orthodontic care.  Although many factors contribute to the dental crowding, this problem usually stems from a discrepancy between space available in each jaw and the size of the teeth.  Aside from aesthetic considerations, poor alignment of teeth may be associated with periodontal problems, abnormal wear and an increased risk of dental decay due to difficulty in maintaining proper oral hygiene.

Deepbite

Excessive vertical overlapping of incisor teeth called “overbite” is generally found in association with a discrepancy between the length of the upper and lower jaws.  It usually results in excessive eruption of either the upper or lower incisors or both.  Associated problems include: 1) excessive display of gum tissue 2) lip protrusion or entrapment 3) biting the roof of the mouth, and 4) incisor wear.
alt

Openbite

A lack of vertical overlap of the incisor teeth can usually be traced to jaw disharmony or persistent habits (i.e. thumb sucking habits and posturing of the tongue between the front teeth) or excessive vertical growth of one or both jaws.  Early assessment and intervention with these disorders is critical to the overall success.
alt

Spacing

Spaces between teeth are another common problem associated with the need for orthodontic care.  Like crowding, spacing may be related to a tooth-to-jaw size disharmony.  Gum tissue attachments called “frenae” are also a common cause of spacing between front teeth. Incisor protrusion may also lead to spacing.  Other contributing factors to spacing between teeth include atypical or unusually narrow teeth, and missing or impacted teeth.
