Orthodontic treatment plans are fully customized to the needs of the patient. Part of crafting a plan is determining the classification the teeth and face of the patient fall under. There are three possible classifications for each. For a brief overview, click the image below to learn more about how classifications are determined.
Class I is when the relationship between the upper and lower teeth and between the jaws is ideal and the bite is balanced.
Class II is when the lower first molar is closer to the back of the mouth than the upper first molar, causing the upper front teeth and the upper jaw to project further forward than the lower front teeth and lower jaw.
Class III is when the lower first molar is closer to the front of the mouth than the upper first molar, causing the lower teeth and jaw to project further forward than the upper teeth and jaw.
