Comparison of Accuracy of Full-arch Implant Digital and Conventional Impressions.

Comparison of the Accuracy of Digital and Conventional Impression in Edentulous Arch

The goal of this clinical trial is to determine whether the accuracy of digital impressions is comparable to conventional impressions. It will also learn about the clinical effect of different method. The main questions it aims to answer are: Does drug ABC lower the number of times participants need to use a rescue inhaler? What medical problems do participants have when taking drug ABC? Researchers will compare digital impression to conventional impression to see if the accuracy of the digital method.

Participants will:
