Purpose: The aim of this 1-year evaluation was to assess the stability of implants and the responses of the supporting tissues to magnet-retained mandibular implant overdentures.
Methods: Six patients with completely edentulism were enrolled in this study. Each patient received 2 implants with sandblasted with large-grit and acid-etched surfaces in the interforaminal region. The implants were loaded immediately with magnet attachment-retained overdentures. The stability of the implants and periimplant tissues was examined by performing clinical examinations, resonance frequency analysis, and radiographic examinations at 1, 2, 6, 12, and 24 weeks and 1 year after surgery.
Results: Two implants in 2 patients failed. The surviving implants were clinically and radiographically stable. The mean Implant Stability Quotient values were relatively stable, showing no significant differences (P > 0.05). The crestal bone changes were -1.18 ± 0.68 mm, -1.35 ± 0.69 mm, -1.47 ± 0.68 mm, and -1.51 ± 0.74 mm at the follow-up check performed at 6, 12, and 24 weeks and 1 year, respectively. The bleeding on probing index was not significant.
Conclusions: The immediate loading of 2 implants using magnet attachment-retained mandibular overdentures may be a viable treatment option in cases of complete arch edentulism. This clinical approach offers increased stability to conventional dentures.
