Amount of inaccuracy was evaluated after superimposing the 3 coordinates of virtually planned and final implant images, which were obtained using intra-oral scans and scan bodies. Four evaluation parameters were considered: origo-displacement, error depth, apical displacement and angle between the planned and the placed implant.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The average of distortion was 0.71\u00a0mm for the origo-displacement, 0.36\u00a0mm for the error depth, 0.52\u00a0mm for the horizontal displacement and 3.34\u00ba for the error angle.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The major reason of exclusion was CBCT artifacts. Results of this study were aligned with the results of previous studies concerning partially edentulous spaces. CAD\/CAM manufacturing process did not result in significant distortion whilst the biggest part of distortions originated from the surgical process.
