PMMA

DESCRIPTION

For temporary work, we would recommend PMMA to all our customers given that, due to its characteristics, it is the material that best adapts to these frameworks.

PMMA lends itself to natural teeth and implants (on interface) alike, in a wide range of degraded colours and any size, from crowns to full bridges.

PREPARATION

Preparation of the ceramic veneer.

  1. Go over the framework with a green stone.
  2. Sand with aluminium oxide between 110 – 150 μm, (pressure 2.5-3 bars).
  3. Clean the surface with a steam jet.
  4. Oxidation: Maintain for 5 minutes at 900ºC under vacuum, maximum temperature rise (55°C/min).
  5. Then sand with aluminium oxide at 250 μm/3-4 bar and clean the surface again with a steam jet.
  6. Apply the bonding layers and opaquer layers as normally performed in your laboratory.
  7. Then apply the different ceramic veneers according to the manufacturer’s instructions.
