Mandibular and Mental Index in Implant Prosthetic Restorations

Abant Izzet Baysal University186 enrolled

Overview

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.

Inclusion Criteria: * Patients aged 18 years or older * Patients with at least one osseointegrated dental implant restored with an implant-supported prosthetic restoration * Availability of panoramic radiographs at baseline after prosthetic loading, 6 months after loading, and 1.5 years after loading * Complete demographic, clinical, implant-related, prosthetic, and radiographic records Exclusion Criteria: * Patients with uncontrolled systemic disease * Use of medications that may affect bone metabolism * History of radiotherapy to the head and neck region * Implant loss during the follow-up period * Insufficient panoramic radiographic image quality for radiomorphometric measurements * Incomplete clinical or radiographic records

Outcomes

Primary Outcomes

Change in Mandibular Index Values Over Time

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.

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

Secondary Outcomes

Change in Mental Index Values Over Time

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.

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

Association Between Prosthetic Restoration Type and Mandibular Index Values

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.

Time frame: 6 months and 1.5 years after prosthetic loading
