One\u2010hundred eighty equally distributed implants, which were placed either free\u2010handed or sCAIP, constituted the study sample. 3D digital deviations were obtained by superimposing the post\u2010surgical scans on the initial treatment plan.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Angular and linear deviation assessment demonstrated higher implant position accuracy in the sCAIP group. sCAIP revealed similar outcomes independently of the alveolar bone height and sinus floor morphology.
