Abstract

The article presents a novel digital workflow for computer-assisted implant surgery (CAIS) that addresses the challenge of cone beam computed tomography (CBCT) metal artifacts by using a 3D-printed radiopaque impression tray combined with 3D Boolean inversion for same-day implant planning. This method eliminates the need for fabricating a traditional radiographic template, reducing patient visits and improving the trueness of 3D data alignment compared to the conventional double-scan technique. The workflow was validated in vitro on a 3D-printed model with metal liners, demonstrating higher accuracy in implant planning despite the presence of metal artifacts. The study suggests further in vivo research to confirm clinical applicability and highlights the potential advantages of this approach in improving guided implant surgery efficiency and precision.
