Purpose:
The aim of this study was to assess and compare patient satisfaction and time required between silicon rubber impression and intraoral scanning impression.
Methods:
Six undergraduates participated in this study. silicon rubber impression and intraoral scanning impression were taken, the time required to obtain the impressions and the scores of visual analog scale(VAS) were recorded. SPSS 23.0 software package was used for statistical analysis.
Results:
The time and patients satisfaction of silicon rubber impression were better than intraoral scanning impressions, and there were significant differences between the two groups(P<0.05).

Using silicon rubber impression, the patient experience is better. To use intraoral scanning impression technology, dentists should be more skilled. With the role-playing method,dental interns can learn the operation key points and precautions of different impression-taking methods even better.
