Abstract
Abstract Background Accurate impression registration is essential for transferring the three-dimensional (3D) implant position to the definitive cast, ensuring passivity of the final prosthesis. Various impression techniques have been developed to optimize accuracy, particularly for angulated implants. This study aimed to evaluate and compare the accuracy of open-tray impression copings, clips impression copings, and hexed implant mounts in transferring implant positions for both straight and angulated implants. Methods Five implants with different angulations (three at 0°, one at 15°, and one
