› “The use of CERCON Zirconia frameworks allows<br />

clinicians the necessary load-bearing capability<br />

(>1,300 MPa) required to support both single-unit<br />

<strong>and</strong> long-span restorations.”<br />

David A. Little, DDS<br />

Private practice, San Antonio, TX.<br />

CAD/CAM system has the ability to mill<br />

all-ceramic zirconia restoration copings,<br />

as well as to mill a new polyurethane<br />

material, CERCON Base Cast, <strong>and</strong> then<br />

burn it out to fabricate PFMs conventionally.<br />

Dental restorations from systems<br />

such as CERCON® not only produce<br />

exceedingly accurate scans <strong>and</strong> digital<br />

models—virtually matching the<br />

patient’s natural intraoral morphology—but<br />

they also allow clinicians <strong>and</strong><br />

technicians to provide faster service,<br />

Benefits of CERCON ®<br />

■ Accuracy—Fast, precise CAD<br />

scans to 10 µm with the CERCON®<br />

Eye laser scanner.<br />

■ Aesthetics—The natural translucency<br />

of CERCON® Zirconia provides<br />

an excellent aesthetic foundation,<br />

which is further enhanced with<br />

the fluorescence of Ceramco®<br />

PFZ porcelain.<br />

■ Performance —At over 1,300 MPa<br />

of flexural strength, CERCON®<br />

crowns <strong>and</strong> bridges have a higher<br />

fracture resistance than other allceramics<br />

<strong>and</strong> are suitable for anterior<br />

or posterior restorations up to 47 mm<br />

in length.<br />

■ Versatility—Offers dental laboratories<br />

versatility with Compartis, an<br />

outsourcing service, <strong>and</strong> CERCON®<br />

Cast, a resin block for milling PFM<br />

<strong>and</strong> other frameworks.<br />

■ Simplicity—CERCON® restorations<br />

are cementable or bondable<br />

<strong>and</strong> use the same conservative tooth<br />

preparation as PFMs.<br />

■ Confidence—Proven to withst<strong>and</strong><br />

the test of time with over<br />

10 years of clinical success <strong>and</strong> a<br />

seven-year warranty against zirconia<br />

framework breakage.<br />
