Evaluating the surface and color stability of 3D printed dental restorations
Official title: "Comparative Evaluation of Surface Topography and Color Stability of Implant Supported Provisional Restorations Fabricated Using Two Different 3D Printing Materials in Mandibular Posterior Region: A Randomized Clinical Trial"
Run by Postgraduate Institute of Dental Sciences Rohtak · NCT06947070 · Data updated 2026-11-12
This study is testing two different 3D printed materials for dental restorations to see which one keeps its color and surface quality better for patients getting temporary implants in their back teeth.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include partially edentulous patients with maintainable oral hygiene and adequate bone quality for implant placement.
✕Probably not a fit
Patients with infections at the proposed implant site or conditions that hinder healing 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 study aims to compare the surface topography and color stability of implant-supported provisional restorations made from two different biocompatible 3D printed materials in the mandibular posterior region. Patients attending the Department of Prosthodontics at the Post Graduate Institute of Dental Sciences in Rohtak will be screened and selected based on specific inclusion and exclusion criteria. A total of 24 samples will be fabricated, with 12 samples from each material group, and evaluated using a profilometer and spectrophotometer after intraoral use. The study is designed as a randomized clinical trial to ensure unbiased results.
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 gone: While there have been studies on 3D printed dental materials, this specific comparative evaluation of surface topography and color stability is relatively novel.
