Abstract
PURPOSE: The purpose of this case series was to investigate treatment outcomes of maxillary sinusitis associated with peri-implantitis at sinus floor augmented sites for a 3-year follow-up. MATERIALS AND METHODS: Eighteen implants in 8 patients diagnosed with maxillary sinusitis associated with peri-implantitis were reviewed. Four patients were treated with implant removal and antibiotics, and 4 patients were treated with implant removal, the modified Caldwell-Luc operation (CLOP), and antibiotics. Seven patients, who had 7 survived implants, were followed up to 3 years after treatment. The characteristics between failed and survived implants were compared. Radiographic parameters of survived implants were analyzed using the Friedman test. RESULTS: Eleven failed implants from 8 patients exhibited approximately 10-mm pocket depths and mobility at diagnosis. Seven survived implants from 7 patients exhibited no significant changes in crestal bone loss at the facial side for 3 years after the treatments. Sinus mucosal thickening was significantly reduced during the 3-year follow-up after the treatments. CONCLUSION: The progression of peri-implantitis in sinus floor augmented sites may lead to maxillary sinusitis. To confirm the efficacy of the intraoral approaches, such as the modified CLOP, systematic clinical studies with a large sample size and a long-term follow-up should be conducted.
