Abstract

Unerupted maxillary anterior teeth is not a common case, However it may present practitioners with management problem. The cause of impaction is considered to be multifactorial, and local cause is the most common. These impacted teeth require surgical intervention, removal, transplantation, or surgical exposure, with or without orthodontic traction to align the malpositioned tooth. The preferred option is surgical exposure and orthodontic correction. Surgical intervention and orthodontic correction should not be delayed to avoid unnecessary difficulties in aligning the tooth in the arch. Surgical exposure should be performed with the intent of providing sufficient attached gingiva rather than simply uncovering the crown, which results in only alveolar mucosal attachment. Attached gingiva is essential to secure the gingival tissues to the adjacent teeth at the dentogingival junction. Thus preventing loss of periodontal tissues as a result of the pull of the surrounding soft tissues and facial muscles. Labially impacted maxillary anterior teeth uncovered with an apically positioned flap technique have more un- esthetic sequelae than those uncovered with a closed-eruption technique. In the case of severly displaced impacted teeth, autotransplantation ensures preservation of the alveolar bone and will facilitate future placement of an osseointegrated implant once growth has ceased or if ankylosis/resorption of the transplant occurs.
