Abstract
This study was carried out to evaluate the clinical utility and complications of IAT Fit Ⅱ® dental implant, an osseointegrated dental implant. Twelve patients, consisting of four patients each with oral cancer, traumatic tooth-loss or excessive gag reflex, served as subjects. They had difficulty in using conventional soft-tissue supported dentures. According to the manual, 581AT Fit Ⅱ® fixtures were placed in the jaws and supported 20 superstructures. All patients were treated with implant-retained overdentures or implant-supported prostheses. With a median follow-up period of 25 months, 57 of 58 fixtures (98.3%) were clinically osseointegrated. Although two fixed screws were fractured and one abutment was loosened, they were successfully replaced. All 12 patients were conscious of recovery of their oral function and were satisfied with their prostheses.
These results suggested that IAT FitⅡ® dental implants are useful for the oral rehabilitation of patients with difficulty in wearing conventional removable dentures.
