Abstract

It is a relatively common clinical experience to see an unerupted maxillary central incisor. This phenomenon is apparent at the dental age of almost eight years and over. Among the possible cause for failure of eruption, ectopic development of the tooth germ is mentioned. This is not fully understood but trauma or periapical imflammation of primary predecessors is accepted. The case with no history of trauma may be impacted by the periapical imflammation of primary predecessors. For bringing into the tooth eruption and the continued normal root developement by the Hertwig's epithelial root sheath, there are early considered of surgical invention and orthodontic traction with removable appliance. We reported successful treatment for inverted maxillary central incisor with proper eruption and normal root developement by forced eruption using removable appliance. But further observation will be required to evaluate the final root developement state and amount of keratinized attachment gingiva.
