Description
Deep bite
“There is excessive vertical overlap (> 2mm) of the upper and lower incisor crowns when in occlusion.”
– Cobourne and DiBiase 2010
There are two types of anterior open bites: Dental deep bite and Skeletal deep bite.
A dental deep bite only patient should typically have no abnormal facial pattern. The lower teeth can be crowded and retroclined leading to a deep bite.
A skeletal deep bite can be caused by multiple factors (discussed in diagnosis). There is usually a brachyfacial (short facial height) profile and it is often associated with a skeletal Class II malocclusion. Severe over-eruption of the incisors can occur.
