Immediate implant placement following odontogenic cyst enucleation : a case report

Odontogenic cysts are among main causes of jaw destruction. Radicular cyst is the most common diagnosis of all odontogenic cysts and a fairly easily diagnosed entity with approximately equal sex distribution. While odontogenic cysts are one of the main causes of jaw destruction, it is mandatory to detect these lesions as early as possible to minimize any necessary surgery. The case of a bone defect restoration after a radicular cyst enucleation using guided bone regeneration procedure with immediate implant placements in the first premolar postextraction alveolus and in the first molar region is presented. The patient was a 50-year old female with an odontogenic cyst of the first premolar in the right maxilla and a second molar root resorption caused by an impacted third molar. Patient had undergone local anesthesia and the extractions of the maxillary first premolar and second molar with partially resorbed roots were carried out. Enucleation of the cyst was performed after a full-thickness periosteal flap creation and an immediate implant was placed. The remaining bone defect was filled with a xenogenic bone substitute and covered with a bioresorbable collagen membrane. Surgical extraction of the impacted maxillary third molar was performed and immediate implant placement in the postextraction alveolus was performed. A histopathological analysis was performed on the enucleated specimen which confirmed the diagnosis of a radicular odontogenic cyst. No significant clinical or subjective problems were noted during the interim partial denture wearing period. After a healing period of 6 months, osseointegration of the inserted dental implants was assessed with a resonance frequency analysis. Implant stability quotient mean scores for the first premolar and first molar implants were 74 and 78, respectively. The implants were further used as a base for a fixed partial denture. The patient exhibited neither clinical nor radiological complications throughout the following 12-month period of clinical monitoring after the final prosthodontic rehabilitation and functional loading of the inserted implants.
