Ten conventional polyether double mixing impressions and ten intraoral scans were made. After cementation, slices were prepared by cutting each tooth for five times. The marginal fit was microscopically analyzed at 20 measuring points per tooth. The analysis based on the seven parameters defined by Holmes et al. [1].
