Recently different protocols have been developed for the implementation of intraoral scanning in full-arch implant workflows, as horizontal scan body scanning, 1 reverse scanning 2 and scan body systems with an integrated verification jig 3 . The aforementioned approaches are aiming to reduce the inaccuracies related with the implementation of intraoral scanners in full-arch implant cases and to improve the efficiency of the whole digital workflow. However the efficiency of these methods and the parameters that can influence their accuracy, as the design of the scan body have not been investigated.
The purpose of the present in vivo study is to compare the trueness and the precision of the recorded implant's position, between conventional and novel implant acquisition protocols.
