Evaluating bone loss around different types of dental implants

Evaluation of Marginal Bone Loss and Associated Factors Around Ziacom Dental Implants With Different Prosthetic Connection

Not applicable Interventional Universidad de Granada · NCT05859113

This study is testing if different types of dental implants cause different amounts of bone loss and inflammation to see which one is better for keeping your bone health stable.

What this trial studies

This study investigates the marginal bone loss associated with Ziacom dental implants featuring different prosthetic connections. It aims to compare bone levels, bacterial contamination, and inflammatory markers around implants with conical connections versus those with internal hexagonal connections. The research will track these factors over time to understand their impact on bone health and implant stability. The hypothesis suggests that hexagonal connections may lead to greater bone loss due to a more harmful microbiome and increased inflammation.

Who should consider this trial

Good fit: Ideal candidates are individuals with one missing tooth in the premolar or molar area who have both opposing and adjacent teeth.

Not a fit: Patients with uncontrolled diabetes, autoimmune diseases, or severe hematologic disorders may not benefit from this study.

Why it matters

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

How similar studies have performed: Other studies have explored similar factors in dental implants, but this specific comparison of connection types is relatively novel.
