Step-by-step: A better screw-retained zirconia prosthesis
Luke Kahng shows how to create a beautiful zirconia restoration using CAD/CAM and layering techniques.
In Figure 3, the author has created a wax mandibular try-in for the dentist to try in the patient's mouth. After doing so, and receiving approval from the patient, the dentist sent it back to the lab. The author then mounted it on the cast model and duplicated it, noting teeth size and length. He then did a preliminary scan and design, putting back whatever is necessary to the facial area. During the scan, he could then measure the first cut back on the lower anterior teeth numbers 22-27âapproximately a 7/10 inch cut.
