In which dental arch is hyperdontia more commonly found?

Hyperdontia, which refers to the condition of having an excessive number of teeth, is more commonly found in the maxilla, or the upper dental arch. Research indicates that individuals are more likely to experience supernumerary teeth in the maxillary region compared to the mandible, or lower jaw. The reason behind this prevalence may relate to the anatomical development and growth patterns of the maxillary region, which is associated with specific tooth formation and eruption processes.

In cases of hyperdontia, supernumerary teeth often appear in locations such as the midline, molar regions, or the area of the canines in the maxilla. This pattern is not only supported by clinical evidence but is also considered in diagnostic evaluations of dental anomalies. In contrast, while hyperdontia can occur in the mandible, it is significantly less common.

Understanding the distribution of hyperdontia in different dental arches is essential for clinicians in both diagnosis and treatment planning. This knowledge assists in anticipating possible complications and providing appropriate interventions for patients exhibiting this condition.
