EVALUATION OF MARGINAL DISCREPANCYAND MICROLEAKAGE OF LAVA ULTIMATE (RESIN NANO CERAMIC) VERSUS LITHIUM DISILICATE (IPS E.MAX CAD) ENDOCROWNS. IN VITRO STUDY
Journal Title: Indian Journal of Scientific Research - Year 2016, Vol 7, Issue 1
Abstract
2 Extra coronal restoration for endodontically treated teeth is preferable. Endocrowns have become a promising alternative in the functional recovery of endodontically treated molar teeth. Lava Ultimate Resin Nano Ceramic (RNC) blocks express the unique biomechanical complex (monoblock). Reducing the marginal discrepancies and microleakage of a restoration is attained by preventing the luting material fromdissolution and exposure to oral environment. Natural teeth were assigned into 2 groups according to the material of endocrowns. Group 1: (4 each): LAVA Ultimate. Group 2: (4 each) E.Max CAD. The crown portion of all molars were removed perpendicular to the long axis and subjected to standard endodontic treatment. Scanning, designing and milling of endocrown restorations corresponding to each tooth preparation. Endocrowns were cemented and thermocycled. Each specimen was photographed using USB Digital microscope with a built-in camera. A digital image analysis system was used to measure and qualitatively evaluate the gap width. Dye penetration depth was measured with using USB Digital microscope with the built-in camera. It was foundE.max group that recorded higher vertical marginal gap mean value Lava Ultimate(76.99 ± 5.04 !m) than (69.51 ± 7.1 !m) and was statistically non-significant (P>0.05) as indicated by student t-test. The vertical marginal discrepancy of the E.max CAD and Lava Ultimate endocrowns fall within the clinically acceptable range <120 !m.
