Angle's classification

Angle's classification is a system used by dentists to categorize how the upper and lower teeth align when the jaws are closed. It helps diagnose bite issues by analyzing the position of the first molars, which are the back teeth. There are three main classes: - Class I: normal alignment, with the upper molar slightly ahead of the lower. - Class II: the upper molar is shifted forward compared to the lower, often causing overbite. - Class III: the lower molar is ahead of the upper, leading to an underbite. This classification guides treatment planning for correcting bite problems.
