The effect of scanned area on the accuracy and time of anterior single implant scans: An in vitro study

Abstract Objectives To investigate the effect of scanned area on accuracy and scan time intraoral scans an anterior implant. Materials methods Three operators experienced in scanning (at least 2-year experience) performed partial complete-arch (n = 10) a dentate resin model with implant at left central incisor site by using scanner (Trios3; 3Shape, Copenhagen, Denmark). Each partial- or was superimposed to reference from laboratory (Ceramill Map 600; Amann Girrbach AG). Mean distance (selected 7 points) angular (mesiodistal buccolingual) scanbody deviations test (trueness) their variance (precision) were calculated. Linear-regressions (trueness), two-sided F-tests Bonferroni correction (precision), multiple linear regressions (scan time), operator as covariate applied (alpha .05). Results Interactions found between for trueness all points angles, except point 6 implant-abutment connection mesiodistal plane (p Partial-arch times significantly shorter, overall, each Conclusions Partial single implants resulted similar accuracies, not influenced time. Scan partial-arch shorter. Clinical significance can be used fabrication monolithic crowns because completed shorter without compromising accuracy.
