A Case Report on Gardner Syndrome With Dental Implant Treatment and a Long-Term Follow-Up.

A case of Gardner syndrome (GS) in a 37-year-old woman is presented in which rehabilitation with dental implant treatment was followed for 7 years. The course of diagnostics and treatment is followed through an overview of 45 tissue biopsy and cytology samples during a period of 30 years. The patient was diagnosed with GS after a routine review of an oral panoramic radiograph presenting with multiple osteomas and multiple unerupted supernumerary teeth. Biopsy results and surgical procedures with histopathologic diagnoses from 1986 to 2016 are presented. Histologic analysis of the sampled jawbone showed a picture similar to an osteoid osteoma. The installed implant was functionally stable, with no clinical or radiographic events observed at yearly visits, for 7 years. In 1991, benign tumors appeared; in 2014, multiple adenomas were found in the small intestine and rectum. This case report shows the potential for dental implant treatment in a patient with GS.
