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.
