Which malocclusion is listed as associated with deep bite?

• A. Open bite
• B. Distal bite
• C. Mesial bite
• D. Crossbite

Answer: (B)

Deep bite is defined by an excessive vertical overlap of the incisors, so the front teeth meet and cover more of the lower teeth than normal when the jaws bite together. This pattern often occurs with a distal (Class II) molar relationship, where the upper jaw sits ahead of the lower jaw and the bite tends to close with the anterior teeth overlapping deeply. The mechanics that accompany a distal bite—such as a retrusive mandible and the way the posterior teeth contact—can promote greater overbite, producing a deep bite. Open bite, which has no vertical overlap, is the opposite. A mesial bite (Class III relationship) typically features a reduced overbite or even anterior open space in many cases, and a crossbite involves sideways or transverse misalignment rather than an excessive anterior overlap.
