Comparative Analysis of Marginal Adaptation and Internal Fit of Zirconia Implant Suprastructures Fabricated Using Different Scanning Strategies

Abstract: This study aims to compare the marginal adaptation and internal fit accuracy of zirconia implant suprastructures fabricated using two different scanning methodologies. Specimens were designed using dental CAD software, and the marginal discrepancies and internal fits were evaluated using microsections and a stereoscopic microscope. Results indicated that both study groups exhibited larger internal gaps in the marginal and axial regions compared to the specified cement space. However, the mean values in the scan body group were significantly lower than those in the scanned abutment group. The differences observed between the two groups can be attributed to the varying optical properties and geometries of the objects during scanning.
