How many malocclusions (bad bites) are there?
In a word: many. The almost infinite variations in possible abnormalities of the jaws and teeth make for a great deal of variations. The orthodontist generally categorizes them in different “Classes”, characterized by deviations in the three planes of space: front to back (sagittal), side to side (transverse) and up and down (vertical). They can result in excessive overbites, underbites, crossbites or any combination. Furthermore, teeth can be crowded or spaced depending on too much or too little space in the dental arch.
