Comparing biofilm on zirconia and titanium dental implants

Comparison of Biofilm Accumulation on the Surface of Zirconia Versus Titanium Implants. Randomized Controlled Pilot Clinical Trial

NA · Universidad Complutense de Madrid · NCT06075017

This study is testing whether dental implants made of zirconia or titanium collect different amounts of biofilm and how that affects patient satisfaction over a year.

What this trial studies

This clinical trial aims to evaluate the differences in biofilm accumulation on zirconia versus titanium dental implants. A total of 30 single implants will be placed in different patients, with 15 made of zirconia and 15 made of titanium. The study will assess the amount and type of biofilm, along with other parameters such as bleeding on probing and patient satisfaction, at 3, 6, and 12 months post-implantation. Statistical analyses will be performed to determine the significance of the findings.

Who should consider this trial

Good fit: Ideal candidates include adults of both sexes who require a single dental implant and meet specific health criteria.

Not a fit: Patients with uncontrolled systemic diseases or those who cannot attend follow-up appointments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved dental implant materials that reduce the risk of infection.

How similar studies have performed: While there have been studies on dental implants, this specific comparison of biofilm on zirconia versus titanium is relatively novel.
