Displasia frontonasal.

Abstract

Developmental disorders are those conditions that are manifested by defects in the embryogenesis of the affected region.The human face begins its formation around the fourth week of intrauterine life and is manifested thanks to the fusion of five prominences: two pairs known as maxillary and mandibular and odd one known as frontonasal.When this fusion is not carried out in an optimal way, numerous developmental alterations appear, such as cleft lip and palate and frontonasal dysplasia.Frontonasal dysplasia frequently produces ocular, nasal and oral affections.Among the oral manifestations, and atypical form of clef lip and/or palate, dental affections and alterations in the growth of the face stand out.Given the great relationship that this condition has with the oral cavity, it is important for the dentist to know the etiology and clinical characteristics of this disorder.
