Effect of Scanning Techniques on Accuracy of Mandibular Fixed Detachable Prostheses

This crossover clinical study aims to evaluate the influence of three different intraoral scanning techniques on the scanning accuracy and passive fit of mandibular implant-supported fixed detachable prostheses in completely edentulous patients. Each participant will undergo digital implant scanning using three methods: splinted scan bodies, horizontal non-calibrated scan bodies (IO Connect), and auxiliary geometric devices.
