Odontogenesis, which is an extraordinarily complex process, like rest of embryonic development, is exposed to certain factors that may alter its normal evolution. Sometimes we see a number of additional teeth to normal dental formula, and if we speak of supernumerary teeth, hyperdontia or hipergenesia. Supernumerary teeth are more common in men than in women. And no wonder that may lead to retention of permanent teeth or hinder its eruption in the dental arch. Hipergenesia diagnosis is made from a though clinical examination with a complete radiographic study by panoramic radiography supplemented with periapical radiographs, occlusal, etc. Supernumerary teethare located mainly in the anterior midline of the maxilla, in which case we speak of mesiodens. The supernumerary tooth mesiodens is seen more often. Supernumerary teeth are more common in permanent dentition and more common in the maxilla than the mandibule. The most common approach of supernumerary teeth is extraction, but sometimes must be supplemented by orthodontic treatment.

Palabras clave : Supernumerary teeth; hipergenesia; hyperdontia; mesioden.
