Comparing color stability and surface roughness of different types of dental restorations

Comparative Assessment of the Color Stability and Surface Roughness of Implant-Supported Provisional Restorations Fabricated by Conventional Technique, Milling and 3D Printing: A Randomized Controlled Clinical Trial.

NA · Postgraduate Institute of Dental Sciences Rohtak · NCT06946693

This study is testing which method of making temporary dental implants—traditional techniques, milling, or 3D printing—keeps its color and smoothness the best for patients with missing teeth.

What this trial studies

This clinical trial evaluates the color stability and surface roughness of implant-supported provisional restorations made using three different techniques: conventional methods, milling, and 3D printing. Patients with partially edentulous conditions will be screened and selected based on specific inclusion and exclusion criteria. A total of 36 samples will be prepared, with 12 samples from each fabrication method, and the outcomes will be measured using a spectrophotometer and a profilometer after intraoral use. The study aims to provide insights into the best practices for provisional restorations in dental implants.

Who should consider this trial

Good fit: Ideal candidates are partially edentulous patients with maintainable oral hygiene and adequate bone quality for implant placement.

Not a fit: Patients with infections at the implant site or conditions that hinder healing may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved aesthetic and functional outcomes for patients receiving dental implants.

How similar studies have performed: While there have been studies on provisional restorations, this specific comparison of fabrication techniques is novel and has not been extensively tested.
