Brief Summary

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.

Conditions

Dental Implant; Prosthetic Restoration

Keywords

Dental implants; Mandibular index; Mental index; Prosthetic restoration

Outcome Measures

Primary Outcomes (1)

• 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.

  Baseline after prosthetic loading, 6 months after loading, and 1.5 years after loading

Secondary Outcomes (2)

• Change in Mental Index Values Over Time

  Baseline after prosthetic loading, 6 months after loading, and 1.5 years after loading

• Association Between Prosthetic Restoration Type and Mandibular Index Values

  6 months and 1.5 years after prosthetic loading

Study Arms (5)

Single Crown Group

Eligibility Criteria

• Sex: all
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The study population consisted of adult patients who received implant-supported prosthetic rehabilitation at Bolu Abant Izzet Baysal University Faculty of Dentistry and had complete clinical and panoramic radiographic records at baseline after prosthetic loading, 6 months after loading, and 1.5 years after loading.

You may qualify if:

• 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

You may not qualify if:

• 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
