1 Introduction Accurate recording of implant positions is essential for achieving a precise fit of complete-arch fixed dental prostheses (FDP) [1-3]. Conventional intraoral optical scanning (IOS) has been widely used for digital impressions, but struggles with accuracy in complete-arch implant cases [1, 4-7]. While IOS performed reliably for single crowns and short-span restorations [8], its accuracy diminishes over larger spans due to stitching errors and scan misalignment [1, 7].
