EVALUATING FRACTURE RESISTANCE and MARGINAL INTEGRITY of CRYSTAL ULTRA CERAMIC RESIN HYBRID MATERIAL COMPARED to E.MAX- IN VITRO STUDY // MS // Prof. Dr. Nadia Fahmy // Dr. Ahmed Kamal Ebeid (2017-2018)

Material type: materialTypeLabelBookSeries: DENTISTRY DISTINGUISHED PROJECTS 2018. Publisher: Giza MSA 2018Description: 7 P. 30 CM.Subject(s): Dentistry -- CRYSTAL ULTRA CERAMIC -- EVALUATING FRACTURE -- MARGINAL INTEGRITYDDC classification: 616 Online resources: FULL TEXT PRESS HERE Summary: Hybrid Ceramics have been recently introduced where ceramics have been combined with composite resins to solve the brittleness property of ceramics as well as providing modulus of elasticity close to that of dentine. A newly launched hybrid restorative material claimed to be the strongest restorative material in terms of compressive and flexural strength. The purpose of this study was designed to compare the marginal integrity and facture resistance of 3-unit e.max and Crystal Ultra FDP after thermocycling. Conclusion: Crystal Ultra Fixed Dental Prosthesis presented statistically higher mean marginal integrity values after aging than the IPS e.max CAD group. Fracture resistance of IPS e.max CAD group displayed statistically significant higher mean value than the Crystal Ultra group

Hybrid Ceramics have been recently introduced where
ceramics have been combined with composite resins to solve
the brittleness property of ceramics as well as providing
modulus of elasticity close to that of dentine. A newly launched
hybrid restorative material claimed to be the strongest
restorative material in terms of compressive and flexural
strength. The purpose of this study was designed to compare
the marginal integrity and facture resistance of 3-unit e.max
and Crystal Ultra FDP after thermocycling. Conclusion: Crystal
Ultra Fixed Dental Prosthesis presented statistically higher
mean marginal integrity values after aging than the IPS e.max
CAD group. Fracture resistance of IPS e.max CAD group
displayed statistically significant higher mean value than the
Crystal Ultra group
