About this study
Official title: Comparison of Peri-Implant Tissue Health and Biomarker Outcomes Between Short and Standard Dental Implants: A Prospective Study
This study compares two types of dental implants, short implants (6 millimeters or less in length) and standard implants (longer than 8 millimeters), to evaluate their effect on the health of the gum and bone tissue surrounding the implant. Approximately 40 patients receiving a total of 80 dental implants will be followed. Researchers will assess clinical signs of gum health around the implants, measure specific protein levels (biomarkers) in the fluid surrounding the implants associated with gum disease. The goal of this study is to determine whether implant length affects the risk of inflammation or infection around dental implants, which may help guide treatment decisions in the future.
Read the detailed description
This is a prospective study enrolling approximately 40 patients who will receive a total of 80 dental implants, categorized as short (≤6 mm) or standard (>8 mm) in length. Peri-implant crevicular fluid (PICF) samples will be collected at baseline from all patients. In patients who develop peri-implant mucositis, an additional PICF sample will be collected at 1 and 3 months. PICF samples will be analyzed by ELISA for RANKL, OPG, cathepsin-K, and cytokine levels. Implant diameter and length will be recorded for each patient. Clinical parameters of peri-implant tissue health will also be assessed at each visit. The study aims to compare biochemical and clinical outcomes between short and standard implants to determine whether implant length influences peri-implant tissue health.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Peri-Implant Crevicular Fluid RANKL Level
Receptor activator of nuclear factor kappa-B ligand (RANKL) levels in peri-implant crevicular fluid (PICF) will be measured using enzyme-linked immunosorbent assay (ELISA) and compared between short and standard implant groups.
Measured: Baseline; 1 and 3 months after non-surgical peri-implant therapy in participants who develop peri-implant mucositis.
Change in Peri-Implant Crevicular Fluid OPG Level
Osteoprotegerin (OPG) levels in peri-implant crevicular fluid (PICF) will be measured using enzyme-linked immunosorbent assay (ELISA) and compared between short and standard implant groups.
Measured: Baseline; 1 and 3 months after non-surgical peri-implant therapy in participants who develop peri-implant mucositis.
Change in Peri-Implant Crevicular Fluid Cathepsin K Level

Questions about this trial
What is this clinical trial studying?
An observational study of Peri-Implant Mucositis, run by Inonu University at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 18 Sep 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Kubra Aral (05330578801, drkubraaral@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Peri-Implant Crevicular Fluid RANKL Level (time frame: Baseline; 1 and 3 months after non-surgical peri-implant therapy in participants who develop peri-implant mucositis.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07828067, which also lists 3 linked publications.
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.
