What are all the possible dental malocclusion there is for teeth?

Too many: There are too many to discuss but here are some. Crossbite, excessive/negative overjet, single tooth issues, multiple teeth issues, quadrant issues, palatal impingement, vertical maxilary excess, prognathic, retrognatic, size discrepancies, microdontia, macrodontia, fusion, gemination, etc...

Three types: Dentrist classify malocclusions as type one two or three based on the position of the upper first molar and lower first molar. We also describe people as having an under bite, overbite or a cross bite based on teeth position. A model of teeth is need to show you. I hope this helps.

Endless: Some one suggested 3. This is the old angle classification, which refers to molars only. I can tell you malocclusion's are like fingerprints, no two are exactly the same (at least it seems so after 30 years of treating them). 32 teeth and endless spatial organization of those "elements"= endless.

4 basic types: Class i front-to-back ok class ii division 1 & division 2 upper protrusion or lower retrusion class iii upper retrusion or lower protrusion add to this deep bite, open bite, cross bites, midline deviations, crooked teeth, crowded teeth, tipped teeth, rotated teeth, and so many more problems. See an orthodontic specialist to evaluate your occlusion...It's painless.

Malocclusion: Almost any way you can think of-lower jaw too forward, too far back, too far to the side , -teeth that come in sideways, teeth that leane to the left or right or forward or back.
