Abstract

Ectopic eruption of the first maxillary molars shows a prevalence of 2 to 6% and is classified in two different types: I) "Jumping type" or "reversible ectopic eruption" II) "holding type" or "irreversible ectopic eruption". Different local as well as hereditary factors have been considered as responsible for the ectopic eruption. "Right on time" diagnosis and treatment subsequently, make the latter efficient and mainly easier for both the patient and the treating dentist.
