Comparing short and standard dental implants for partial tooth loss

Prospective Observational Study on Evolution of Extra-short Implants (<6.5 mm) Compared to Non-extra-short Implants (≥ 6.5 mm) Splinted on the Same Prosthesis

Observational Fundación Eduardo Anitua · NCT04927819

This study is testing whether shorter dental implants work as well as standard-length ones for people who have lost some teeth.

What this trial studies

This observational study aims to evaluate the survival rates of short-length dental implants (less than 6.5 mm) in patients with partial edentulism, using standard-length implants as a control. The study will also assess clinical parameters such as marginal bone loss and complications related to the prosthetic devices. Participants will receive either type of implant as part of a fixed multiple prosthesis, and their outcomes will be monitored over time. The study is designed to provide insights into the effectiveness of shorter implants in dental restoration.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who require a fixed multiple prosthesis supported by either short or standard-length implants.

Not a fit: Patients who smoke more than 10 cigarettes a day or those needing complete or unitary prostheses may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide evidence supporting the use of shorter dental implants, potentially improving treatment options for patients with partial tooth loss.

How similar studies have performed: While there is ongoing research in the field of dental implants, this specific comparison of extra-short versus non-extra-short implants is relatively novel.
