Which deep occlusion type is described as hereditary?

• A. Roof type
• B. Covered
• C. Collapsed
• D. Lateral

Answer: (B)

The attribute most often linked to heredity in deep bite patterns is the one where the upper teeth markedly cover the lower incisors. This tendency to an excessive overbite tends to run in families because it reflects inherited skeletal relationships and tooth-size proportions, so genetics plays a strong role in its presence. The other patterns are more often tied to environmental or acquired factors—habits, tooth loss, wear, or functional shifts—rather than a fixed genetic inheritance, which is why they’re less commonly described as hereditary.
