"Class II" typically refers to a classification system used in various fields, including education, medicine, and engineering. In education, it may denote a specific grade level or category of students, while in medicine, it can refer to a type of medical device that poses moderate risk and requires regulatory oversight. In the context of orthodontics, "Class II" describes a dental relationship where the upper teeth significantly overlap the lower teeth, often leading to an overbite. This classification helps orthodontists like Dr. Edward Angle, the founder of modern orthodontics, determine the best treatment options for patients.
