In this course, we are going to examine some of the most fundamental concepts that dental professionals need to know when classifying occlusion.

There are three types of Class I malocclusion according to Edward Hartley Angle’s classification:Type I: The teeth angle toward the tongue.Type II: Includes narrow arches with the upper teeth sticking out and lower teeth leaning in toward the tongue.Type III: The upper front teeth angle toward the tongue and crowding is present.WHAT IS CLASS II MALOCCLUSION?A Class II malocclusion is when the upper teeth stick out over the lower teeth and affect the overall bite alignment, also known as an overbite. This type of malocclusion is often severe enough that orthodontic intervention is recommended. While it may take a little more time to shape the bite to a more natural state, it is still possible to do so with the right appliances and approach to treatment.
