Class I Malocclusion: A condition in which molars are correctly aligned, but there is an anterior/posterior crossbite, an open bite or overcrowding on the arches.
Class II Malocclusion: Also known as an overbite. This condition is characterized by the positioning of the upper front teeth further forward than the lower teeth.
Class III Malocclusion: Also known as an underbite. This condition is characterized by the positioning of the lower front teeth further forward than the upper teeth.
Closed Bite: The upper front teeth completely overlap the bottom teeth causing a deep overbite.
Congenitally Missing Teeth: Some permanent teeth fail to develop and erupt due to hereditary factors.
