Abstract:
Objective:To evaluate the reliability and accuracy of 3DSS-Ⅱ color structured-light scanning system for scanning and reconstructing the model of abutment tooth.Methods:5 plaster maxillary abutment tooth models were scanned and reconstructed by 3DSS-Ⅱ color structured-light scanning system,and then the 3D shapes of the models were measured by Geomagic 6.0 software and the plaster models were measured by manual with vernier caliper.The data were statistically analyzed.Results:The graphs of point-cloud were obtained from scanning surfaces of abutment tooth models.There were close correlations and no significant differences between different groups(r≈1,P
