The growing presence of digital intra oral scanners create a perfect match to the CT-based surgical guide workflow. Also, thanks to the magic of point cloud merging, there is no need for any CBCT scanning appliance whatsoever. This is the new norm for most surgical guides. Essentially, no scanning appliance is needed because the existing teeth are tasked as markers. Because there needs to be a good dispersement of markers, this technique requires that the patient have at least 3 teeth (and/or healing abutments) with an AP (Anterior-Posterior) and left-right spread of at least 20mm (i.e. almost all partially dentate cases).
Facilities / equipment needed:
2) Optional: Scan of opposing arch if articulator setup is to be used for the waxup.
