Common Problems

  • Class II

    Class II

    Class II problems represent an abnormal bite relationship in which the upper jaw and teeth are located in front of the lower jaw and teeth. Class II patients usually exhibit a convex facial profile with a recessed chin. A skeletal Class II problem occurs when the upper molars are forward of the lower molars. This gives the patient the appearance of having a recessed lower jaw, a protruding upper jaw, or both.

  • Class III

    Class III

    In this instance, the lower jaw and teeth are positioned in front of the upper jaw and teeth. The lower jaw may appear to be excessively large, but in many cases the lack of upper jaw development is at fault. Several treatment options are available to correct a Class III problem.

  • Psuedo Class III

    Pseudo Class III

    Pseudo Class III, particularly in younger patients, is a function of habit rather than hereditary factors. A misaligned bite may cause the lower teeth to bite forward of the upper teeth, giving the appearance of a Class III.

    Interceptive treatment is imperative to prevent abnormal growth of both the upper and lower jaws.

  • Crowding

    Crowding

    Crowding of the teeth is probably the most common orthodontic problem. Although many factors contribute to dental crowding, this problem typically stems from a discrepancy between the space in each jaw and the size of the teeth.

    Crowding is often one of several orthodontic problems. Crowding can be the cause or result of other problems, such as impacted teeth, retained teeth or teeth that do not naturally fall out. Crossbite of the front or rear teeth can also cause the teeth to become crowded.

  • Spacing

    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. Spacing may occur between the front and the back teeth. Tooth size discrepancies, such as smaller teeth or abnormally shaped teeth, can also create abnormal spacing.

  • Deep Incisor Overbite

    Incisor Overbite

    Also known as an overbite, a deep bite is excessive vertical overlapping of the front teeth and is generally found in association with a discrepancy between the length of the upper and lower jaws. It usually results in excessive eruption of the upper or lower incisors, or both.

  • Openbite

    Openbite

    An openbite can occur with the front teeth, known as an anterior openbite or with the back teeth, referred to as a posterior openbite. An anterior openbite is the lack of vertical overlap of the front teeth and can usually be traced to jaw disharmony or habits such as thumb sucking or the posture of the tongue pushing against the front teeth. A posterior openbite is a problem in which the back teeth do not meet vertically, which keeps the jaw from functioning properly.

  • Excess Gingival Display

    Excess Gingival Display

    Also known as a gummy smile, this orthodontic problem gives the appearance of excessive exposed gums on the upper arch. There are several treatment options for this problem. In severe cases, corrective jaw surgery may be necessary to actually shift the jaw upward vertically reducing the amount of exposure of the upper gum tissue.

  • Posterior Crossbite

    Crossbite

    A posterior crossbite will usually result from a narrow upper jaw or abnormally 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 accommodating position, the lower teeth are located outside the upper teeth.

    A posterior crossbite can involve one side of the jaw, known as a unilateral crossbite, or both sides of the jaw, known as a bilateral crossbite.
