In Vitro Comparative Analysis Of Digital Posts And Cores: Accuracy Of Different Intraoral Scanners and Scanning Techniques, Assessment of the fracture resistance of Different Materials. In Vitro Comparison of Digital Posts and Cores: Impression, Design and Manufacturing

Description :

This research investigates the evaluation and comparison of post and core systems in restorative dentistry, with a focus on innovative materials such as PEEK, zirconia, and hybrid materials (Vita Enamic (3M), Numerys GF (ITENA)). The primary aim is to analyze the accuracy of digital models obtained using state-of-the-art dental scanners and to evaluate the mechanical properties and fracture resistance of these materials. In this context, accuracy (trueness and precision) refers to the degree to which a digital model represents the true geometry of the physical object. Specifically, the study will focus on the trueness of the scanners, which reflects how closely the digital models match the reference scans obtained from micro-CT imaging. Advanced imaging techniques, such as micro-CT scanning, are used to provide precise comparisons between the digital models and reference scans. The general context of this project is driven by the need to improve the durability and precision of post and core systems in dentistry, particularly with the advent of new materials. Although previous studies have explored traditional post and core systems, few have compared these innovative materials under controlled experimental and clinical conditions.
