Troubleshooting Guide Pala Denture Acrylics

Pour the powder in steadily and quickly while stirring 30 sec. mixing thoroughly – 30 sec. saturation time.

Place plaster model in lukewarm water for 10–15 min, or in a pressure pot (without pressure!).

Apply two thin layers of Aislar insulation to the plaster model, always carefully pat off interdental excess

Ensure that the expiration date has not yet occurred. Store away from light, always use fresh liquid in a separate small bowl, use a clean brush, and dispose of excess insulation. Protect the insulation from contamination (residual plaster, brush with metal ferrule).

Set pressure at 2 bar Observe dwelling time for Paladon 65 and Paladon ultra.

Use a dosing cup.

Observe the instructions for use (extended processing periods for cold-cured polymers Palapress vario and PalaXpress)

After pressing, ensure that there are sufficient distortions available.

Kulzer water bath polymerisation

Completely clean all wax residue from the plaster model

Ensure that the expiration date has not yet occurred. Store away from light, always use fresh liquid in a separate small bowl, use a clean brush, and dispose of excess insulation. Protect the insulation from contamination (residual plaster, brush with metal ferrule).

Do not use insulation that contains oil or alcohol.

The insulation on the plaster model may no longer be moist. Each insulation layer must be well-dried. Avoid puddle formation.

Use Type 3 Octa Dur yellow.

The impression must be carefully cleaned to remove blood, saliva and disinfectant, etc. Rinse with clear water.

Clean the device daily, adhere to the dosage in the manufacturer's instructions. Preferably do not use wax solvent.

Only heat the flask for about 5 minutes and remove the wax while it is still pliable, clean the plaster surfaces with plenty of clear, boiling water.

Extend the drying time for insulation on cold plaster.

Use the polymerisation temperatures and times prescribed in the current instructions for use.

Use the dwelling and polymerisation times prescribed in the current instructions for use.

Comply with specifications regarding the handling of the impression, insulation and model fabrication; avoid excessively long evaporation and boiling out of the plaster model

Cold curing acrylics 15 – 20 minutes (depends on denture acrylic), 55 °C, 2 bar. Injection procedure 30 minutes, 55 °C, 2 bar. Polymerise heat-curing acrylics in accordance with Kulzer water-bath polymerisation: heat up to 70 °C in 30 min, maintain temperature 90 min. Bring to the boil in 20, boil for 30 min, then cool slowly in a water bath.

Storing the denture in water after finishing is recommended - ideally overnight, but preferably longer.

Storing the denture in water after finishing is recommended - ideally overnight, but preferably longer, even when the patient is at home (ideally in lukewarm water).

Adhere to the prescribed mixing ratio.

Observe the working time.

Bring to the boil in 20, boil for 30 min, then cool slowly in a water bath.

Check materials to be used.

Observe the manufacturing date or expiration date (powder + fluid have a shelf life of 2 - 3 years).

Apply two thin layers of Aislar to the plaster model, isolation must be fully dry.

The impression must be carefully cleaned to remove blood, saliva and disinfectant, etc. Rinse with clear water.

Boil out using clear, hot water

Avoid excessive boiling-out and steam-cleaning of the plaster model.

Ensure that the expiration date has not yet occurred. Store away from light, always use fresh liquid in a separate small bowl, use a clean brush, and dispose of excess insulation. Protect the insulation from contamination (residual plaster, brush with metal ferrule).

Mix plaster under vacuum

The plaster should not still be steaming (just above body temperature).

Store opened powder dry and at temperatures between approx. 10 °C and max. 25 °C

Set pressure at 2 bar.

Observe polymerisation time in the pressure pot.

Apply two thin layers of Aislar separator to the plaster model

Do not polymerise cold-cured polymers at temperatures above 55 °C.

Cool down slowly (heat-curing acrylic in water bath) - deflask denture at a maximum of body temperature!

Prepare mixture according to the directions for use.

Clean with toothbrush and toothpaste.

Reduce contact pressure and monitor temperature

Always pat off excess insulation in interdental spaces; carefully remove interdental Palabond accumulations with compressed air.

Inject acrylic when the surface in the filling cylinder is matte and dry; avoid draughts around the vial; monitor ambient temperature (polymerisation is accelerated at higher temperatures)

Soak for approx. 30 sec., stir for 30 sec. and then pour into the filling cylinder.

Adhere to the dosing instructions (e.g. PalaXpress casting technique 10 g : 7 ml, injection techniques 30 g : 15 ml)

Change the brush or use a brush without a metal frame if the metal is dissolved by Palabond.

Roughen teeth with a coarse diamond or by sandblasting (50 µm) directly before filling with acrylic.

Use a pure plaster investment.

Apply bonding agent to the roughened surfaces and allow to penetrate for 30 seconds. Repeat process.

Palabond is effective for 10 minutes after application. Further processing must occur within this period.

Do not evaporate wax residue. Instead boil out with clear, boiling water; clean the denture teeth with monomer before isolation if required

Incorrect powder/liquid ratio.

Flask too hot during deflasking.

Rinse the flask with cold water.

Tension due to delayed relining

Premature contacts and incorrect load distribution due to tooth malposition
