OPC

OPC 3GTM Porcelain is a pressable ceramic system that delivers consistent bridges which are
reliable and durable. The needle-like crystalline structure is made up of a lithium disilicate, glass
ceramic material which inhibits crack propagation. The crystal free overlay porcelain is kinder to
opposing dentition and polishes to a glossy high shine. Recommended for three unit anterior bridges or
anterior/posterior single unit applications. 3G(tm) Porcelain is twice the strength of the previous
generation of pressable ceramics.

Greater Control of Optical Properties
Optimal Pressable Ceramic (OPC) is comprised of a combination of materials that enhance the ability to
mimic natural dentition. Because Optimal's core and powders are made from similar ceramic materials
and are color coordinated to compliment each other, you have considerably more control over the
translucency levels throughout your restoration. The result - a lifelike simulation of natural dentition.

High Flexural & Compressive Strength
Our Ceramic Engineers have reduced the size of the leucite crystal and improved its distribution without
reducing the total crystalline content, therefore increasing strength and reliability. This gives it a
compressive strength of over 23,000 psi. The ceramic used in Optimal has over eight years of
successful clinical history.

Impeccable Fit
Optimal provides an extremely high degree of fit to the tooth. This, of course, results in increased load
bearing capacity. To you and your patient, this means less time in the chair, fewer adjustments and
long restoration life.

Why prescribe 3G Esthetics?
The patented technology of 3G Esthetics allows dental laboratories to produce consistent,
high-strength, lithium disilicate, glass-ceramic restorations. The microstructure, consisting of needle-like
crystals, results in a strong framework highly resistant to cracking. The new 3G® HS pellet will
consistently produce restorations with impeccable marginal integrity and has increased core strength
by over 40% compared to the original 3G pellet. The increased strength of 3G HS enables
conventional cementation techniques to be utilized under proper clinical conditions.

The coefficients of Thermal Expansion (CTE) for the core and the overlay porcelain are precisely
matched, making them compatible and highly fracture resistant (core CTE = 10.3 ppm; overlay
CTE=9.8 ppm).
