PORCELAIN SYSTEMS Clinical studies prove the long-term strength and esthetics of Cerinate Porcelain. Cerinate combines superior aesthetics with the strength to resist occlusal stresses. The patented formulation is feldspathic, yet has the high strength of some aluminous porcelains. This unique combination provides great strength and reliability in high stress occlusal restorative situations while producing extremely aesthetic results. A 18-year clinical study at the University of Maryland unequivocally proves the longevity and aesthetics of Cerinate. One hundred percent of the Cerinate Porcelain laminates were retained, with no debonds, all receiving a 100% Alpha rating for color stability! What makes Cerinate superior to other porcelains? Restorations look natural because Cerinate Porcelain can be made very thin and translucent while retaining its high strength. You can use Cerinate for reversible laminate veneers because this conservative procedure increases patient acceptance. Prepping is virtually eliminated. In addition, Cerinate Porcelain has thermal expansion characteristics similar to enamel. Its flexural strength falls in a range occupied by aluminum oxide reinforced core porcelains. Reliability is just as important a property as strength. Reliability is often measured by the Weibull Modulus method. Researchers measured the Weibull Moduli for Vita Alpha (Vita) and Empress Glass Ceramic (Ivoclar) and Corum Porcelain (Vivadent). Other studies have also documented the superiority of Cerinate Porcelain. The Australian Therapeutic Goods Administration (ATGA) concluded that Cerinate Porcelain is as strong as aluminous porcelains like Hi-Ceram and Vitadur N. Additional research was conducted at the University of California, Los Angeles comparing four different porcelain-composite systems. The materials tested were Cerinate, Vitadur N, Ceramco H and G-Cera. The findings of the study reported that Cerinate with Ultra-Bond was the only system that achieved 100% retention and no cracking or crazing due to polymerization shrinkage. All other systems exhibited porcelain cracking and crazing due to polymerization shrinkage as well as high amounts of microleakage.
