Abstract
Objective:The aim of this study was tocomparesimilarity of virtual image of the restoration maxillary in-cisor with all ceramic crown by CEREC®CAD mirror-image (MI) model and biogenericreconstruction (BR) model as well as manual wax-ups(WU). Method:Thirtyparticipants with intactdentitions,symmetric incisors andnormal occlusal morphol-ogy were includedrandomly. Impressions,biteregistrationsand three gypsum replicas were made.Preparationsof one of the max-illary incisor on modelfor all ceramic crowns were performed andscanned.The virtual imageof restorations were formed by us-ing the modes of MI and BR(CEREC®v4.2).WU of these preparationswere scanned as well.Differences were evaluated vi-suallyby matching the virtual images ofscan with the contralateraltooth morphologies. The discrepancieswere compared a-monggroups of MI,BR,andWU viaWilcoxon signed-rank test (α=0.05). Result:The groups of MI and WU got higher scoresthan that of BR(P <0.05),but no significant discrepancies were found between MI and WU (P >0.05). Conclusion:The CAD-MIand manual WUareall suitable techniquesin aestheticalrestoration of anterior teeth , but the former is more effi-cient than the latter.关键词
