Forty\u2010eight identical maxillary incisor replicas containing cemented fibre posts were randomly allocated to three navigation\u2010guided groups and a freehand group (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200912). Virtual drilling paths were planned from cone\u2010beam computed tomography images, and all procedures were performed by a single operator. Pre\u2010 and postoperative micro\u2010computed tomography scans were used to measure coronal, apical and angular deviation. All navigation\u2010guided groups showed significantly lower apical and angular deviation than the freehand group, whereas no significant differences were observed among the three navigation\u2010guided systems. Coronal deviation was similar across groups. One navigation system required significantly less operative removal time than the other groups without compromising accuracy. Within the limitations of this laboratory study, dynamic navigation improved the precision of fibre post removal compared with the freehand technique.\n
