Prognatismo - Overview

Nombres alternativos

Mentón extendido

Definición:

Es una extensión o protrusión del maxilar inferior (mandíbula) que ocurre cuando la forma de los huesos de la cara hace que los dientes estén alineados de manera incorrecta (desalineados).

Consideraciones generales:

El prognatismo puede causar oclusión dental defectuosa (desalineación de las superficies oclusoras de los dientes superiores e inferiores), lo que le da a algunas personas una apariencia de enfado o de peleador. El prognatismo puede ser un síntoma de diversos síndromes o afecciones.

Causas comunes:

Una mandíbula extendida (prominente) puede ser parte del contorno facial normal con el cual una persona nace.

También puede ser causada por afecciones hereditarias tales como el síndrome de Crouzon o el síndrome de nevo de células basales.

Igualmente, se puede desarrollar con el tiempo en niños o adultos como resultado de afecciones tales como gigantismo o acromegalia.
