Easy cementation with the KATANA Zirconia Block

In 1983, Kuraray introduced the patented MDP monomer in its PANAVIA EX cement. 35 years later, MDP monomer-based resin cements have been scientifically proven to provide the most favourable bond values when cementing zirconia. With the recent introduction of the all-ceramic KATANA Zirconia Block, cementation is still best achieved with the PANAVIA and CLEARFIL families of products.

Cementation to zirconia

The KATANA Zirconia Block possesses a tooth-like translucency and impressive flexural strength, making it a preferable option to lithium silicate glass. For strong and reliable bonding to the existing tooth structure, it is best to use PANAVIA V5 Tooth Primer for the pretreatment of the tooth and CLEARFIL CERAMIC PRIMER PLUS for the priming of the restoration. Since both of these utilise MDP monomer technology, you can be assured of easy adhesion with the PANAVIA V5 system.

Kuraray Noritake offers full-adhesive cementation with PANAVIA V5 and self-adhesive cementation with PANAVIA SA Cement Plus. Both products are designed for durable cementation of zirconia-based restorations with unparalleled procedural simplicity and predictability. PANAVIA SA Cement Plus also incorporates a high concentration of MDP monomer to offer increased chemical reactiveness and adhesion with zirconia.

A dentist’s perspective

Dr Alexandre Pereira Monteiro is a dentist who runs his own implant surgery practice in Cessy in France. Dr Pereira’s interests, though varied, lie primarily in aesthetic and CAD/CAM dentistry, and he has used the KATANA Zirconia Block since 2018. “I think these new ranges of zirconia have many advantages,” he says. “They combine aesthetic properties with translucency parameters similar to those of lithium disilicate glasses with a much higher resistance to bending and abrasion.”

For cementing restorations made with the block, Dr Pereira likes to use PANAVIA V5. “As a user of many adhesive systems, I know PANAVIA V5 very well,” he says.

“PANAVIA V5 has the benefit of being a system that is very polyvalent in its indications while also being very tolerant. It offers a simple, unique and easily reproducible protocol that will satisfy the majority of practitioners. Special mention must be made of the opaque version, as it is very effective for hiding a metal structure or a strongly dyschromatic tooth.”
