INTRODUCING LRF™
2
This innovative new leucite-reinforced feldspar ceramic
block offers the highest aesthetics of traditional
feldspathic porcelain with added flexural strength by
adding the perfect combination of leucite ceramic.
Leucite reinforcement of glass ceramic offers increased
flexural strength and resistance against possible crack
formations and chipping at the margins.
The particle size and particle distribution of the leucite
crystals contribute to the aesthetic appearance as they
reflect the incident light in nature the same way. These
ceramic particles are homogeneously distributed and
dense providing your patients restorations that are not
only beautiful and aesthetic, but strong and durable
as well.
THE GC INITIAL™ LRF BLOCK FROM GC AMERICA IS AN EXCEPTIONALLY AESTHETIC AND STRONG LEUCITE-REINFORCED FELDSPAR CAD/CAM BLOCK. IT HAS A FAST MILLING TIME, DOES NOT REQUIRE FIRING AND IS EASILY FINISHED, SAVING TIME WITHOUT COMPROMISING STRENGTH AND BEAUTY.
FAST, STRONG, BEAUTIFUL
FAST AND EASY: JUST MILL, POLISH AND CEMENT• High density - less risk of cracking and chipping
• Extremely smooth surfaces after milling
• Easy-to-polish or glaze with dedicated glaze paste
• Chameleon effect offers optimal color integration

PHYSICAL PROPERTIES
• Combines qualities of high and low-strength CAD/CAM ceramic blocks
• Initial™ LRF is stronger than traditional feldspar glass ceramic blocks
BEST OF BOTH WORLDS
• Highest fracture stability and flexural strength in its category, whether polished or glazed
• High density block (less risk of chipping)

CLINICAL CASE
First upper molar showing a defective amalgam restoration.
Decision to create a ceramic onlay directly in CAD/CAM.
Contact, occlusion, and anatomy are finalized
intra-orally.
Luting using G-CEM LinkForce™.
Cavity preparation following an all ceramic criteria.
Final result after glazing (not characterized
in this case).
GC Initial™ LRF Block just after milling.
