Which deep occlusion type has a hereditary character?

Which deep occlusion type has a hereditary character?

• A. The roof type
• B. Covered
• C. Collapsed
• D. Lateral

Answer: (B)

Genetic influence can shape how a deep bite manifests, and among the deep occlusion types, the one described as covered is the form most commonly inherited. In a covered deep bite, the vertical overlap of the upper teeth over the lowers is pronounced, and this pattern often runs in families—relatives show similar tooth overlap and occlusal relationships across generations. This familial resemblance points to underlying genetic factors controlling vertical facial dimensions and eruption patterns, making the trait relatively stable and less responsive to change from habits or environmental adjustments. The other types tend to be more variable and more strongly influenced by non-genetic factors, so they don’t show the same clear hereditary pattern.
