What term is used for a malocclusion where the upper teeth bite inside the lower teeth?

Explanation:
Crossbite describes a malocclusion where the upper teeth bite inside the lower teeth. This occurs when the maxillary teeth occlude lingually (or buccally in some cases) to the mandibular teeth, causing an abnormal bite relationship that can be seen in one side (unilateral) or both sides (bilateral), and in the back (posterior) or front (anterior). This is different from crowding, which is misalignment due to insufficient space; diastema, a gap between teeth; and drift, the movement of teeth over time after space changes.
