Proven in clinical situations
since 1993, Cristobal+ offers excellent esthetics and natural translucency
that defies detection in the mouth. The material's exclusive post-curing
polymerization process creates restorations with high hardness values, great
overall flexural strength for exceptional fracture resistance and superb
marginal integrity, making it the system of choice for indirect restorations.
Cristobal + is so strong, it requires no substructure or framework of any
kind. Yet, it is non-antagonistic, protecting opposing teeth while still
supplying tremendous wear resistance. Cristobal +'s nonporous, biocompatible
surfaces provides superior chairside polishability that is virtually impermeable
to microorganisms. And, as they are mechanically polished, not glazed, the
finish lasts indefinitely. There has never been a laboratory fabricated
non-porcelain restoration that you can polish to such a lustrous natural
shine! Clean-up with Cristobal + is a snap. The luting agent literally flicks
off the material. The Materials
The superior hardness of Cristobal + is due to its high degree of resin
polymerization and the extraordinary bonding between the glass and polymer
matrix. The Barium Borosilicate glass filler (approximately 74% by weight)
in Cristobal + provides excellent matrix cohesion for strength, wear resistance
and esthetics. The polymer (Bis-GMA based mixture - approximately 26%
by weight) binds together the glass particles and demonstrates superior
handling. The Process
Cristobal + offers an impressive combination of elasticity and wear resistance
through the highly cross-linked structure that develops during its two-stage
curing process. The material offers greater resistance to localized resin
deformation caused by chewing and/or hard food particles and a flawless,
polished appearance. Additionally, the new post-curing unit improves overall
flexural strength for exceptional fracture resistance and increases the
cure to avoid flaking. |
