Introduction: We aim to determine and compare the correlation between conventional digital impression methods for measuring mesiodistal teeth dimensions. Methods: This cross-sectional analytical study was conducted on a total of 120 dental arch samples with less than 5 mm tooth crowding, complete arch, no missing teeth, fillings mesial or distal sides at Can Tho University Medicine Pharmacy. Conventional (extra-fast alginate) impressions using 3D intraoral scanner (CEREC Primescan) were taken from all participants, dimensions measured. Using R software, Pearson’s coefficients used analyze methods. Result: The pooled maxilla 0.8062 [95% confidence interval (CI): 0.7751–0.8334] (very strong positive correlation); mandibular, it 0.7645 (95% CI: 0.7165–0.8054) (strong correlation), both jaws 0.7863 0.7581–0.8115) correlation). Conclusion: In Vietnamese population measurement width can be instead plaster models.
