Management and Rehabilitation of Dentigerous Cyst With 10-Year Follow-Up: A Case Report.

Odontogenic cysts are fluid-filled sacs arising from tooth-developing tissues within the jawbone, often causing swelling, pain, or displacement of teeth. A dentigerous cyst, specifically encapsulating the unerupted tooth's crown, can interfere with dental development by displacing teeth, causing resorption of adjacent teeth, and complicating dental or surgical interventions. This case report represents a long-term follow-up of a 35-year-old male with a large mandibular dentigerous cyst extending to the lower right border of the mandible, associated with a horizontally impacted third molar in the lower right mandibular region. The treatment consisted of cone beam computed tomography(CBCT) evaluation, followed by enucleation of the cyst with the extraction of second and third molars, root canal treatment (RCT) of the first molar, followed by autogenous symphyseal bone graft placement. Eighteen months later, the implant was placed with respect to the missing second molar. After osseointegration, an implant-supported crown was placed.
