The effect of different scanning protocols on precision and trueness of intraoral scanning: A pilot trial.

Background: The aim of this study was to investigate how different scanning protocols affect the accuracy (trueness and precision) of intraoral scanning of complete arches with implant cylinders.

Material And Methods: A master model was designed with five cylinders. One scanner, TRIOS2 (3shape), was used to scan the model with four different scan protocols: ROCK (wavelike scanning in a pendulum movement), ZIGZAG (wavelike scanning technique), OBP (occlusal, buccal, and palatal), and OWBP (occlusal, wiggling, buccal, and palatal).
