Abstract
Impacted canines are commonly associated with the development of dentigerous cysts, which can be extensive if they are identified late. The surgical management of such cysts by enucleation and extraction can result in significant bony defects that can complicate patient's comprehensive management. This case report presents the conservative interdisciplinary management of an impacted canine associated with an extensive dentigerous cyst. The treatment involved enucleation and extraction of the impacted canine, an initial period of passive eruption of an impacted tooth into the resulting bony defect, followed by an active orthodontic movement and conservative restoration of the substituted premolar. This technique allowed the resolution of the bony defect without resorting to bone grafting.
