Direction to Use
STEP1. POWDER AND LIQUID DISPENSING
a) The standard powder to liquid ratio is 1.45g / 0.5mL. b) For accurate dispensing of powder, lightly tap the bottle against the hand. Do not shake or invert. c) Close bottles immediately after use.
STEP2. MIXING
a) Dispense powder and liquid onto a heavy glass slab. b) Using a stainless steel spatula divide the powder into 3 equal portions. Incorporate one portion of powder into ALL the liquid and spatulate thoroughly for 10 seconds. Successively incorporate the remaining portions and spatulate thoroughly. The total process should take 60-90 seconds. Working time is 3-4 minutes from start of mixing (Temperature : 23±1°C, Relative humidity : 50±10%).
Note : The correct consistency is obtained when the mixture lifted with the spatula is drawn out into a slender peak, breaks and resettles slowly into the main mass.
STEP3. CEMENTATION TECHNIQUE
a) Prepare tooth using standard techniques. b) Clean with pumice and water only. Wash and dry but DO NOT DESICCATE. DO NOT REMOVE SMEAR LAYER. For pulp capping use calcium hydroxide. c) Clean and dry inside of casting. d) Mix the required amount of cement. e) Coat internal surface of restoration with 1mm of cement and start to seat within 30 seconds of completing mix. (DO NOT OVERFILL). Higher temperatures will shorten working time. f) Net setting time is 7 minutes 10 seconds from end of mixing. Remove excess cement at the first formation of gel stage.
