Comparison of Implant-Supported Permanent Crowns Produced wıth Different 3D Printed Resins in Terms of Productıon Accuracy, Marginal Fit and Internal Fit: A Comparative in Vitro Study
Abstract
PURPOSE: This study aimed to comparatively evaluate the manufacturing accuracy, marginal and internal fit of implant-supported permanent crowns fabricated using different brands of permanent hybrid ceramic resins via 3D printing. Additionally, these outcomes were compared with crowns produced from Vita-Enamic using the subtractive CAD/CAM technique. MATERIALS AND METHODS: Six groups were formed, including five different 3D printing resins and Vita-Enamic. Crown accuracy was evaluated following ISO Standard 12836:2015. For accuracy measurements, root mean square values were calculated and recorded using Geomagic-DesignX software, based on methodologies described in the literature. Marginal and internal fit were assessed by measuring points on sectioned specimens under an optical microscope. Data were analyzed using SPSS version 22.0. RESULTS: The Saremco Crowntec showed (p
