Which condition is associated with delayed tooth eruption due to obstruction from supernumeraries?

Gardner syndrome is a genetic disorder characterized by the presence of multiple osteomas, soft tissue tumors, and impacted teeth, including supernumerary teeth. These supernumerary teeth, which are additional teeth beyond the normal complement, can cause obstruction and delay the eruption of adjacent teeth. This obstruction leads to an affected individual's teeth not erupting at the expected developmental timeline.

In contrast, cleft lip is primarily a structural defect of the lip and may affect tooth development or alignment but is not specifically associated with supernumerary teeth causing delayed eruption. Osteogenesis imperfecta is mainly known for its effects on bone fragility and does not specifically involve supernumerary teeth obstructing eruption. Angelman syndrome, a neurodevelopmental disorder, does not have a direct link to the presence of supernumerary teeth or tooth eruption delays related to them.

Hence, the association of delayed tooth eruption due to supernumerary teeth is prominently seen in individuals with Gardner syndrome.
