Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults over 18 years old who require replacement of a posterior single missing tooth and are in good general health.

Probably not a fit

Patients with conditions such as severe bruxism, periodontitis, or those who have recently undergone tooth extraction may not benefit from this study.

What this trial studies

This clinical trial aims to evaluate the effectiveness of a new variable-thread dental implant design compared to a standard dental implant in patients requiring replacement of a posterior single tooth. The study will assess clinical, radiographic, and patient-reported outcomes to determine which implant design offers better stability and integration with the bone. A total of 24 participants will be randomly assigned to receive either the variable-thread or standard implant, with follow-up assessments to monitor their progress and outcomes.

Why it matters

Potential benefit: If successful, this study could lead to improved dental implant stability and longevity for patients receiving implants.

How similar studies have gone: While there have been limited studies on variable-thread implants, this approach is relatively novel and has not been extensively tested in larger populations.
