3. Remove excess water. Keep moist. Avoid contamination.

IMPORTANT: Be careful not to completely dry the surface. Surface should be glistening.

CAPSULE SYSTEM

• Powder/Liquid ratio (g/g) 0.72/0.14
• Mixing time (min, sec.) 10 seconds
• Working time (min. sec.) 1’30’’
• Initial setting time (min, sec) 5’00”
• Finishing time @ 37ºC from start of mixing (min, sec) 6’00”
• Minimum delivery/capsule 0.15mL
• Test conditions:temperature (23 ± 1°C), relative humidity (50 ± 10%). ISO 9917-1 (Non translucent radiopaque glass polyalkenoate cement). Minimum net contents per capsule: 0.72g powder and 0.14g (0.12mL) liquid.

1. Activate the capsule by pushing the plunger until it is flush with the body.

Important: Do not click with applicator before you mix.

2. Immediately place the capsule into the Ultramat 2 amalgamator, or any other suitable mixer, and triturate for 10 seconds

3. Immediately remove the capsule and place into the Riva applicator

4. Click the trigger of the Riva applicator until glass ionomer paste is seen through the clear nozzle

5. Fill Riva Silver into the cavity, being careful not to trap air under the restoration.

Note: At 23ºC/74ºF working time will be about 90 seconds (1’30’’) from the start of mixing. In situations above this temperature, working times will shorten. Adhesion strength will decrease if material is manipulated after this time

6. Immediately apply Riva Coat to all exposed surfaces of restoration

7. Light cure for 10 seconds procedure.

8. At least 6 minutes after the start of trituration, finish the restoration using standard techniques

9. Apply another layer of Riva Coat

10. Light cure for 10 seconds

11. Instruct patient not to eat for at least one hour after

POWDER / LIQUID SYSTEM MIXING OF LIQUID AND POWDER:

Powder-liquid dosage: 1 flat scoop to 1 drop

Powder-liquid ratio: 0.300g/0.043g (7:1)

Recommended mixing time: 30 secs.

1. Gently tap Riva Silver powder bottle on the hand

2. Dispense one level measure of powder onto the mixing pad/ glass slab. Replace cap tightly

3. Dispense one drop of Riva Silver onto the mixing pad/glass slab next to the powder. Replace cap tightly

4. Divide the powder into two equal parts

5. Mix the liquid with one part of the powder for 10 seconds using a plastic spatula, then include the second part and mix for another 15 to 20 seconds.
