Verification of accurate crown superimposition during ERP setup generation after direct superimposition between the crowns of the pre-treatment CBCT teeth and the reset appointment laser scan. a Color displacement maps comparing the crown positions of the pre-treatment CBCT crowns and reset appointment laser scan crowns. Green areas indicate 0.0 mm displacement; blue and red areas indicate equal to or greater than 0.75 mm. b, c Histograms showing the distribution of displacements between crowns of the pre-treatment CBCT scan and reset appointment laser scan in the maxillary arch and mandibular arch
