Marginal and internal fit of nano-composite CAD/CAM restorations: So-Hyun Park, Yeon-Jee Yoo, Yoo-Jin Shin, Byeong-Hoon Cho, Seung-Ho Baek; Restor Dent Endod 2016;41(1):37-43. Published online January 19, 2016; DOI: https://doi.org/10.5395/rde.2016.41.1.37

Objectives

The purpose of this study was to compare the marginal and internal fit of nano-composite CAD-CAM restorations.

Materials and Methods

A full veneer crown and an mesio-occluso-distal (MOD) inlay cavity, which were prepared on extracted human molars, were used as templates of epoxy resin replicas. The prepared teeth were scanned and CAD-CAM restorations were milled using Lava Ultimate (LU) and experimental nano-composite CAD/CAM blocks (EB) under the same milling parameters. To assess the marginal and internal fit, the restorations were cemented to replicas and were embedded in an acrylic mold for sectioning at 0.5 mm intervals. The measured gap data were pooled according to the block types and measuring points for statistical analysis.

Results

Both the block type and measuring point significantly affected gap values, and their interaction was significant (p = 0.000). In crowns and inlays made from the two blocks, gap values were significantly larger in the occlusal area than in the axial area, while gap values in the marginal area were smallest (p < 0.001). Among the blocks, the restorations milled from EB had a significantly larger gap at all measuring points than those milled from LU (p = 0.000).

Conclusions

The marginal and internal gaps of the two nano-composite CAD/CAM blocks differed according to the measuring points. Among the internal area of the two nano-composite CAD/CAM restorations, occlusal gap data were significantly larger than axial gap data. The EB crowns and inlays had significantly larger gaps than LU restorations.
