Implication

Randomized trial compares marginal accuracy in digital and conventional impressions, indicating digital methods improve dental restorations.

Key Points

To compare the marginal fit of restorations made using digital and conventional impression techniques.
Thirty extracted human molar teeth were divided into three groups: direct tooth scan, die scan, and control with conventional impression.
All specimens were examined under a scanning electron microscope at 150x magnification.
ANOVA test assessed differences in marginal adaptation among the groups.
Direct scan with VITA Suprinity crowns achieved a marginal fit of 91.3245 μm, better than the indirect scan at 99.0060 μm and conventional technique at 123.0265 μm.
No statistically significant difference was found between groups I, II, and III (F(2,27)=2.481, p=0.103).
Direct digitalization with VITA Suprinity crowns provided the highest accuracy in fit.
