Katana STML Monolithic Zirconia Restorations

To achieve exceptional bond strength when bonding zirconia restorations, MDP-monomer-based cement presents the most favorable bond values compared to those of other resin types of cement.

Since zirconia is a non-silica-based ceramic which cannot be etched with hydrofluoric acid of the internal surface, micro-mechanical retention achieved through sandblasting, and chemical bonding through adhesion are key factors for successful zirconia bonding.

• Pre-Treatment with MDP
  
  Pre-Treatment with an MDP adhesive monomer such as Clearfil Ceramic     Primer will enhance the bond of zirconia restorations.
• CLEARFIL CERAMIC PRIMER PLUS is a single-component adhesive primer used to enhance the bond strength between resin-based materials, as well as porcelain, composite, hybrid ceramics, metal oxide (zirconia), and lithium disilicate. Clearfil Ceramic Primer Plus is very easy to use, since it does not require mixing, and maintains excellent adhesion property in long-term storage due to the optimum combination of ingredients.

  PANAVIA™ V5 and PANAVIA™ SA Cement Plus, which both include MDP adhesive monomer, have high bond strength and durability to zirconia. Designed for all indications including Zirconia.

  
  
  

We recommend that the final occlusal and axial thickness of the Katana STML restorations be 1 mm thick, with gingival margins that can thin to a .3 mm chamfer margin. It is important to keep in mind that the reduction must begin with the final thickness of 1 mm and ad cement gap and drill path of another .4 mm. The actual reduction or total clearance must begin at a minimum of 1.4 mm.
