What does an open bite indicate in dental terms?

The anterior teeth do not contact
The molars are misaligned
The front teeth overlap
The bite is too deep

The correct answer is: The anterior teeth do not contact

An open bite is characterized by a condition in which the anterior teeth do not make contact when the mouth is closed. This means that when a person bites down, there is a noticeable gap between the upper and lower front teeth. Open bites can arise from various factors, including dental habits such as thumb sucking, improper jaw alignment, or the presence of certain orthodontic issues. Understanding that the primary feature of an open bite is the lack of contact among the anterior teeth helps clarify why this definition is essential in orthodontic assessment and planning for treatment. The other provided options describe different dental issues: misalignment of molars pertains more to posterior occlusion, overlapping front teeth relates to an overbite or overjet scenario, and a deep bite indicates a situation where the upper teeth excessively overlap the lower ones. Each of these conditions exhibits distinct characteristics that are not synonymous with an open bite.
