Dental - 3T Frameworks

Veneering instructions

Veneering instructions are as follows:-

• Oxide Firing

• Oxide firing is not necessary

• If you wish to perform Oxide firing, it can be carried out to check the surface at 950-980°C for 5 minutes with vacuum

• Always blast the oxide after firing with 180 mesh Al₂O₃ at 3-4 bar and steam clean

• Ceramic Firing

• Always apply opaque material in 2 firings

• Apply a thin first layer (Washbrand) and second layer opaque

• Wash off part under running water before applying the next ceramic coating

• A cooling period down to 600°C is recommended

• Remove ceramic mechanically only.  Hydrofluoric acid will corrode the metal

• Ceramic

• Use ceramics according to ISO 9693 with firing temperatures of up to approximately 980^oC

• Cement ceramic in accordance with the manufacturer’s instructions

• The 3T Framework material has a Coefficient of Thermal Expansion of 13.9 – 14.3 x 10^-6m/mK
