Accuracy of Complete-arch Implant Scans Obtained Using T-Marker

Sponsor: Menoufia University

Summary

This randomized crossover clinical study will evaluate and compare the accuracy and effective scanning time of complete-arch implant scans obtained using the (TruAbutment,Marker) T-Marker photogrammetry application operated on a smartphone and a tablet. Twenty-four patients with completely edentulous arches rehabilitated with four well-integrated implants connected to multiunit abutments will undergo both digital impression protocols in a randomized sequence. A verified conventional implant cast will serve as the reference standard. Linear and angular deviations between the implant positions obtained using each digital protocol and the reference model will be evaluated using three-dimensional analysis software. Effective scanning time required for implant coordinate acquisition and registration will also be recorded. The study will determine whether the use of T-Marker with a smartphone provides accuracy and scanning efficiency comparable to its use with a tablet.
