Open bite

Open bite is a type of malocclusion where there is a vertical gap between the upper and lower teeth when the mouth is closed. This condition can be classified into two types: anterior open bite and posterior open bite. Anterior open bite refers to a condition where the front teeth do not touch when the mouth is closed, while posterior open bite refers to a condition where the back teeth do not touch.

Causes

Open bite can be caused by a variety of factors, including genetics, thumb sucking, tongue thrusting, and temporomandibular joint disorder (TMJ). It can also be caused by certain habits or conditions that affect the normal development of the teeth and jaw, such as prolonged use of a pacifier or bottle feeding in childhood.

Symptoms

The main symptom of open bite is a noticeable gap between the upper and lower teeth when the mouth is closed. Other symptoms may include difficulty biting or chewing food, speech problems such as lisping, and facial aesthetic concerns.

Treatment

Treatment for open bite depends on the severity of the condition and the underlying cause. Treatment options may include orthodontic treatment, orthognathic surgery, or a combination of both. Orthodontic treatment involves the use of braces or other appliances to move the teeth into the correct position. Orthognathic surgery, also known as jaw surgery, may be required in severe cases to correct the alignment of the jaw.
