Malocclusion — Class II, division I

Malocclusion — Class II, division 1During the development phase of the teeth and facial structures, the upper and lower jaws may grow at different rates, resulting in an improper bite and incorrectly positioned jaw bones. When the lower jaw is under- developed, or the upper jaw is overdeveloped, the lower jaw is positioned far back from the upper jaw. This results in a receding lower jaw, also called a “retrognathic jaw” or a Class II relationship. Individuals with this condition have small chins and may develop bite and jaw joint problems.







Malocclusion — Class II, division 1 (2)Along with the incorrectly positioned jaw bones, the teeth are also misaligned. This is called a Class II malocclusion. The lower teeth are far inside the upper teeth, causing a deep overbite. The upper front teeth may also protrude significantly, causing speech problems. Crowding of the teeth and bite problems are common, due to the lack of growth of the lower jaw. Treatment of this situation may be done with Orthodontics (braces) or may require Facial Surgery, depending on the severity of the condition.
