Mandibular and Mental Index in Implant Prosthetic Restorations
2026年5月23日 更新者:Zeynep AKGÜL、Abant Izzet Baysal University
Evaluation of Mandibular Radiomorphometric Indices in Implant Patients With Different Prosthetic Restorations
This retrospective longitudinal observational study evaluates mandibular radiomorphometric indices in patients rehabilitated with different implant-supported prosthetic restorations.
Clinical and panoramic radiographic records of adult patients with dental implants were retrospectively reviewed.
Mandibular index and mental index measurements were obtained from panoramic radiographs taken at baseline after prosthetic loading, 6 months after loading, and 1.5 years after loading.
The study aims to assess changes in these radiomorphometric parameters over time and to determine whether patient-, implant-, and prosthesis-related factors are associated with mandibular cortical bone-related measurements.
