Multiple Congenitally Missing Teeth Combined with Ectopic Eruption of Canines: Review of Literature and Report of a Case

Abstract

Congenitally missing teeth are fairly common. Ectopic eruption patterns in three quadrants are relatively rare. This article reports an 11-year-old female patient, in which 8 permanent teeth are congenitally missing (upper right second molar and all premolars except upper right first premolar) and three canines except upper right canine are displaced to the position normally occupied by the first premolars. The possible causes of congenital missing teeth and the mechanisms of ectopic eruption were also reviewed.
