Erupção ectópica do primeiro molar permanente

Abstract

Ectopic eruption of the first permanent molar means that the molar erupts at an angle usually mesial to its normal path of eruption, causing an atypical resorption in the distal root of the second deciduos molar. In some cases the permanent molar frees itself and reaches normal oclusion, in others, is needed to bring the permanent molar to oclusion. The prevalence of ectopic eruption has been reported to be about 3%.
