3D analysis of wear in natural teeth and dental prostheses

Natural Dentition, Prosthesis and Antagonist Wear 3D Analysis

Observational Implantology Institute · NCT05637619

This study is testing how much wear happens to natural teeth and dental implants over time using 3D scans to see how different factors affect them.

What this trial studies

This observational study aims to assess the wear of natural dentition and full arch implant-supported rehabilitations using 3D scanning technology. Patients will be scanned at baseline and then at 4, 8, and 12 months, with subsequent scans every 6 months to monitor changes over time. The study will evaluate wear based on the type of dental rehabilitation and opposing arch, as well as factors such as parafunction and the number of implants placed. The goal is to better understand the interactions between dental materials and natural teeth under various conditions.

Who should consider this trial

Good fit: Ideal candidates include fully dentate individuals with at least 10 teeth and edentulous patients receiving full-mouth implant restorations.

Not a fit: Patients with heavy bruxism or those who have changed their full arch rehabilitation during the study may not benefit from this research.

Why it matters

Potential benefit: If successful, this study could provide insights into the wear characteristics of dental materials, leading to improved prosthetic designs and patient outcomes.

How similar studies have performed: While there have been studies on dental wear, this specific approach using 3D scanning for comparative analysis is relatively novel.
