Press release - Cementation of Zirconia

Adhesive cementation of high-translucent zirconium oxide restorations

The definitive integration of full ceramic restorations throws up a lot of questions in everyday practice life. Many of these are answered in the “ACTA Report”. The Congress lectures (ACTA Congress) held by Prof. Matthias Kern (Kiel/Germany) and Daniele Rondoni, ZTM (Savona/Italy) have been condensed down to the essentials and presented in a practical manner. The focus is placed on zirconia materials and it’s adhesive, MDP based cementation.  

Until now, the preferred cementation method for dental zirconia was conventional luting. Through the establishment of high-translucent zirconia materials (e.g. KATANA^TM UTML/STML, Kuraray Noritake Dental), however, the standards have changed. The outstanding aesthetic properties of the new zirconias are to be supported through a composite resin cement. In the ACTA Congress held at the ACTA University (Amsterdam/Netherlands,), Prof. Matthias Kern and Daniele Rondoni, ZTM evinced exciting information on the subject. Prof. Kern underlined the significance of the MDP monomer for the reliable adhesive cementation of zirconia restorations. He is convinced that the chemical adhesion can only take place using MDP based resin cements (PANAVIA^TM, Kuraray Noritake Dental). Rondoni presented the advantages and the material properties of the new zirconias.

In the “ACTA Report”, the scientifically founded explanations, which have proven their worth in practice, have been summarised. The reader learns for example which prerequisites are required for adhesive cementation. In addition, valuable preparation and material-relevant processing guidelines are provided. The explanations on the functional method of the adhesive cementation and the MDP monomer are presented in an interesting way. The original MDP monomer was developed in 1981 by Kuraray in order to improve the bond strength on tooth structure and dental metal alloy. Today, MDP monomer (the basis of PANAVIA^TM resin cements) are characterised by their strong adhesion to metal(oxides) incl. zirconia.

PANAVIA^TM V5 is an aesthetic and adhesive resin cement for all cementation indications, based on MDP technology. Prof. Kern published a work on bonding to zirconia ceramic with MDP for the first time in 1998. His well-founded experiences are practically summarised in the “ACTA Report”.

Today sandblasting and MDP is the proven formula to reliable adhesive cementation of zirconia.

The “ACTA Report” is a recommended read for all dentists and dental technicians who have integrated full ceramic restorations into their everyday working lives. Well-founded and practical!
