Class III Bite (Underbite)

An underbite, also known as a Class III malocclusion, is where the lower jaw is larger than the upper jaw, and is a common jaw relationship found in many people. When a person has normal occlusion, the upper and lower teeth align in such a way that the upper teeth fit slightly over the lower teeth when biting. When a person has an underbite, the mandible (lower jaw) protrudes forward in front of the maxilla upper jaw, causing the lower teeth to overlap the upper teeth when the jaw is closed. This gives the chin and lower teeth a more prominent appearance.
