EVALUATION OF MARGINAL ADAPTATION OF ZIRCONIA ENDOCROWNS FABRICATED USING DIGITAL IMPRESSION TECHNIQUE
Main Article Content
Abstract
Objectives: To evaluate the vertical and horizontal marginal adaptation of zirconia endocrowns fabricated using the digital impression technique. Materials and methods: 20 endodontically treated first maxillary molars were prepared for endocrown restorations. Each tooth was subjected to a digital impression technique using a 3Shape TRIOS 3 intraoral scanner. A total of 20 zirconia endocrowns were fabricated from Ceramill Zolid FX Multilayer blanks. Vertical marginal gaps were measured under a stereomicroscope. Horizontal marginal gaps were assessed using the silicone replica technique. Results: The mean vertical and horizontal marginal gaps were 80,9 ± 10,9 µm and 119,8 ± 9,3 µm, respectively. Conclusion: Zirconia endocrowns fabricated using the digital impression technique showed clinically acceptable marginal adaptation.
