AP DiscrepencyIII?

[mojo]

Hi does anyone know what AP discrepency class III means? I put pictures of my teeth on my other thread("Can I have y'alls opinions")

AP refers to antero-posterior. This type of discrepancy is usually referring to the relative positions of the upper and lower posterior teeth. In a Class 3 discrepancy, the lower posterior teeth are too far forward in comparison to the upper posterior teeth, usually resulting in an underbite tendency.
