Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients aged 18-80 with properly positioned dental implants that have been loaded for more than three years.
✕Probably not a fit
Patients with uncontrolled systemic diseases, pregnant or lactating women, and heavy smokers may not benefit from this study.

What this trial studies
This observational study aims to evaluate how the shape and contour of implant-supported restorations affect the health of soft and hard tissues around dental implants. A total of 120 patients will undergo a clinical and radiographic evaluation, including a digital scan of their crowns using an intraoral scanner. Participants will also complete a questionnaire regarding their dental care routines. The study focuses on patients who have had their implants loaded for over three years and are receiving maintenance therapy.
Why it matters
Potential benefit: If successful, this study could lead to improved design and maintenance of dental implants, reducing the prevalence of peri-implant diseases.
How similar studies have gone: While the specific approach of this study is novel, similar studies have indicated that implant design can influence peri-implant health.
