The aims of this clinical study are: 1) to compare the accuracy of conventional versus digital impression techniques for implant impressions; 2) to assess the passive fit of the prosthesis constructed from the most accurate impression. Thirty edentulous patients who received 4 - 6 implant and indicated for implant-supported fixed prosthesis will be invited. Full-arch conventional and digital impressions will be made for each patient. Accuracy evaluation will be made and the prosthesis will be constructed from the most accurate impression. Passive fit of the zirconia implant-supported prostheses will be verified at the try-in stage clinically and radiographically.
