DESCRIPTION

Prepare site by exposing metal to be covered. Remove surface layer of surrounding old acrylic, if any. Roughen by sandblasting, using a shell blaster or aluminum oxide or stone. Be sure to remove any remaining oxide by rubber wheeling the surface with a pumice impregnated rubber wheel ("Cratex"). DO NOT use an aluminum oxide rubber wheel! Wipe off metal surface with UBAR monomer at repair site. Avoid finger oil on the cleaned metal surfaces.

Dispense appropriate amounts of ProTech® "UBAR" monomer and powder into seperate dappen dishes. Brush on liquid bonding liner in an even, thin layer onto the exposed, cleaned metal using a clean brush. (The reason for preparing the powder and monomer in advance is that once the bonding liner is applied, there will not be sufficient time to pour out the materials before the bonding liner loses its effectiveness!) Immediately after bonding liner application, dip a second, clean brush into the dappen dish containing the monomer in order to get it wet. Then dip the wet brush into the second dappen dish to pick up a bead of powder. Paint a thin layer of the wetted powder over the wet bonding liner. Do not add additional acrylic until this first layer has completely polymerize. 

HIDING CLASPS

In order to achieve an aesthetically pleasing masking of an exposed clasp, it is IMPORTANT TO CREATE AS THIN A LAYER OF ACRYLIC AS POSSIBLE. PRIOR to brushing on the bonding liner, mix the appropriate tooth colors and the opaque TOGETHER to achieve the desired shade and opacity, and set aside in a dappen dish. Since the opaque powder will lighten the tooth colors, it may be necessary to select a darker shade of tooth color in order to make a successful match. (The reason for preparing the powder in advance is that once the bonding liner is applied, there will not be sufficient time to mix the colors before the bonding liner loses its effectiveness!) Then paint on the Bonding Liner and IMMEDIATELY thereafter, brush-dip on the pre-mixed tooth colored acrylic and monomer.

CURING

Allow this first acrylic layer to self-cure for ten (10) minutes on the bench. Due to the high density of "UBAR", pressure potting is not required. Additional acrylic (hard, soft, light-cured or pour) can be applied on top of this first layer using any standard method (pack, pour, salt & pepper, brush dip).

FINISHING & POLISHING

Finish and polish as usual. We recommend the use of the PROTECH® ACRYLIC POLISHING & HI-SHINE BAR for a luxurious long lasting shine.

PATIENT CARE

The patient should care for their prosthesis with the same degree of diligence as required for natural dentition. We strongly recommend that the prosthesis be cleaned with the PROTECH® PROSTHETIC CLEANER. The use of this product will remove all stains, calcium and calculus without the damaging effects experienced with other denture cleaners.
