Abstract

Objectives: The aim of this study is to evaluate marginal and internal fit of lithium disilicate inlays fabricated by conventional and digital impression techniques. Materials and methods: 20 typodonts of the first right mandibular jaw were prepared for the distal-occlusal ceramic inlays at the Preclinical Department, Faculty of Odonto Stomatology, University of Medicine and Pharmacy, Ho Chi Minh City. This study divided ceramic inlays into 2 groups, group 1 including of 20 inlays was made impression by conventional impression (CI) technique, and group 2 including of 20 inlays was made impression by digital impression (DI) technique. All inlays were CAD-CAM milled with lithium disilicate blocks. The replica technique was used to measure marginal and internal adaptation by using stereomicroscopy. Results: No statistical significant differences were detected between groups CI and DI to marginal dicrepancies (p > 0,05). In addition, no statistical significant differences were detected between groups CI and DI to internal dicrepancies (p > 0,05). Conclusion: There were no significant differences in marginal fit and internal fit of lithium disilicate inlays fabricated by conventional and digital impression techniques.
