Infinity-Zir

The blank is the difference

Infinity-Zir is cut from Cercon zirconia. Cercon is Dentsply Sirona's zirconia line, and the legal manufacturer printed on the material is DeguDent GmbH in Hanau-Wolfgang, Germany. That is a verifiable German blank, not a marketing phrase, and it is the reason this tier carries the warranty it does.

When to choose it

• Anterior cases where the patient will be looking closely for years.
• Longer span bridges you do not want to see again.
• Any case where you would rather quote once and never revisit it.

Long span is also where connector design decides the outcome. The prosthodontist who checks your case is first author on a published study of connector design and the flexural strength of zirconia, in the Journal of Indian Prosthodontic Society. More about the lab.

What we need from you

The same preparation discipline as any zirconia case: 1.0 to 1.5 mm clearance, a clean continuous margin, rounded internal line angles, an opposing arch and a bite record, and a shade taken before the tooth dries out. The case sheet lists it all.
