Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients aged 50-65 years who are completely edentulous and have adequate bone structure for implant placement.

Probably not a fit

Patients with systemic diseases, oral disorders, or those who smoke heavily or have psychiatric conditions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to assess bone height changes around dental implants in completely edentulous patients treated with the All on Four technique. Participants will be divided into two groups, receiving different angulations of posterior implants, and will undergo evaluations using cone beam CT at various intervals post-surgery. The study will track changes in bone height around the implants after denture insertion and at 6 and 12 months follow-up. This approach seeks to determine the optimal implant placement for better outcomes in dental restoration.

Why it matters

Potential benefit: If successful, this study could lead to improved dental implant techniques that enhance bone stability and patient outcomes.

How similar studies have gone: Previous studies have shown promising results with similar implant techniques, indicating potential for success in this approach.
