Perfecting the Multi-Unit Implant Scan

Documentation shows that in multi-unit rehabilitation cases utilizing implant restorations, the ability to take a precise impression decreases as the number of implants in the case increases. This lack of precision is due in part to accuracy limitations in implant scanners as well as conventional impression methods. But also, this is because each step in the process depends on the accuracy of the previous step. If one of the steps is off, then the master model will not be an accurate representation of the patient's mouth, and the prosthesis will not fit.  An ill-fitting final fixed prosthesis leads to having to retake impressions or scans, wasted chair-time, and frustration.
