Abstract: Objective: To introduce a novel technique to directly transfer casts scan to the virtual articulator by scanning the maxillary bite registration of the bite fork, so as to improve the accuracy of casts transferring, and simplify the conventional facebow transferring and articulator mounting process. Methods: Transfer fork with the maxillary bite registration is first obtained and fixed to the transfer platform of a lab scanner, then the bite fork is scanned using the scanner, thus transferring the spatial position of the maxillary bite registration to the matched virtual articulator, and then the maxillary cast scan is transferred through the bite registration by matching the same landmarks. The mandibular cast scan is subsequently transferred by matching the maxillomandibular bite registration scan. Results: The casts were successfully transferred to the virtual articulator using the proposed technique, eliminating the conventional transferring and mounting process. Conclusion: Casts scan could be directly transferred to the virtual articulator through scanned bite fork with the maxillary bite registration, which improves the efficiency and accuracy of the virtual articulator transferring procedures.
