摘要： The present invention relates to methods and systems for generating a 3-D dental impression with a corresponding hinge axis position and, in certain embodiments, a condylar guide inclination. In some embodiments, an intraoral scanner and a computer processing system are employed to: i) generate upper and lower jaw models, and first and second occlusal 3-D models with different mouth openings (MOs) or functional positions (FPs), ii) align the models to generate a composite 3-D model, iii) calculate a hinge axis position from the composite 3-D model based on the difference in said MOs or FPs, and iv) mount the 3-D dental impression on a virtual articulator (VA) by aligning the hinge axis position to the hinge axis position of the VA.
