Effect of Composite Material shade on the Accuracy of Overlay restorations, in vitro study.

Description :

Subject: This study aims to investigate whether the shade of composite restorative material (SDR, dentsply sirona, Germany) shade A1, A2, A3 and universal), used usually for cavity floor elevation under thin overlays, affects the accuracy of intraoral scanners (IOS). Additionally, the study will determine whether different scanners (Allied star AS 200E (Straumann Group, China), Helios 680 (Eighteeth, Changzhou Sifary Medical Technology CO. Ltd), Medit i700 (Medit, South Korea), Aoralscan 3 (shining 3D, Hangzhou, China)) are affected differently by composite shade, influencing their ability to capture precise digital impressions.
