About this study
Official title: 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Single Crown Group | Patients rehabilitated with implant-supported single-crown restorations. | |
| Fixed Partial Denture Group | Patients rehabilitated with implant-supported fixed partial denture or bridge restorations. | |
| Removable Prosthesis Group | Patients rehabilitated with implant-supported removable prostheses. | |
| Full-mouth Fixed Restoration Group | Patients rehabilitated with implant-supported full-mouth fixed restorations. | |
| Splinted Crown Group | Patients rehabilitated with implant-supported splinted crown restorations. |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Baseline after prosthetic loading, 6 months after loading, and 1.5 years after loading
Secondary outcomes (2)
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.
Measured: 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.
Measured: 6 months and 1.5 years after prosthetic loading

Questions about this trial
What is this clinical trial studying?
An observational study of Dental Implant and Prosthetic Restoration, run by Abant Izzet Baysal University at 1 site in Turkey (Türkiye).

The record says: finished, as of the sponsor's last update on 29 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Mandibular Index Values Over Time (time frame: Baseline after prosthetic loading, 6 months after loading, and 1.5 years after loading). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2026.
