Mandibular and Mental Index in Implant 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.

Treatment and study plan

Primary outcomes

Change in Mandibular Index Values Over Time

Time frame: Baseline after prosthetic loading, 6 months after loading, and 1.5 years after loading

Mandibular index values measured on panoramic radiographs will be evaluated at baseline after prosthetic loading, 6 months after loading, and 1.5 years after loading to assess longitudinal changes in mandibular cortical bone-related radiomorphometric parameters.

Secondary outcomes

Change in Mental Index Values Over Time

Time frame: Baseline after prosthetic loading, 6 months after loading, and 1.5 years after loading

Mental index values measured on panoramic radiographs will be evaluated at baseline after prosthetic loading, 6 months after loading, and 1.5 years after loading to assess longitudinal changes in mandibular cortical bone-related radiomorphometric parameters.
Association Between Prosthetic Restoration Type and Mandibular Index Values

Time frame: 6 months and 1.5 years after prosthetic loading

Mandibular index values will be compared among patients rehabilitated with different implant-supported prosthetic restoration types, including single crowns, fixed partial dentures, removable prostheses, full-mouth fixed restorations, and splinted crowns.
