Features
Ideal for minimally invasive dentistry
Riva Self Cure is the ideal restorative material for use in minimally invasive dentistry (MID) as it is a bioactive material which prevents caries from occurring. Natural tooth structure is preserved, so large cavities and undercuts are not necessary.
Great marginal adaptation
Riva Self Cure is the answer to long term microleakage prevention. Use it as a restorative or a base under permanent restorations. “....self-cured glass ionomer bases were more effective in reducing microleakage in both the occlusal and proximal cavo surfaces than a fl owable resin.
Bioactive proprietary technology
Riva Self Cure utilizes SDI’s proprietary ion glass fi ller developed by our glass technologists. Ion glass is a radiopaque, high ion releasing, bioactive glass used in SDI’s range of glass ionomer products. Riva Self Cure releases substantially higher fl uoride to assist with remineralization of the natural dentition.
Bulk fill to save time.
Riva Self Cure can be bulk fi lled to minimize chairside time.
The strongest dentin replacement
When dentin is missing, use Riva Self Cure to replace it. It is the best dental material available today that virtually mimics dentin. No adhesive is required, and sensitivity is nonexistent. Like dentin, Riva Self Cure has a very high compressive strength, ensuring it will withstand long-term mastication forces.
BPA and HEMA Free
Riva Self Cure does not contain Bisphenol A (including it’s derivatives) or HEMA. Use this product on your patients with confidence and peace of mind.
Choice of viscosities
Riva Self Cure easily extrudes into the cavity, but for an exceptional packable, high viscosity material, use Riva Self Cure HV. You have a choice.
Surface hardness
The greater the surface hardness, the greater the resistance to abrasive wear. Riva Self Cure is a dynamic glass ionomer restorative material that can withstand high penetration of the surface.
Low acid erosion
Riva Self Cure has a very low acid erosion value. This improves the longevity of the restoration, resisting disintegration and wear caused by oral acidity. The ISO Standard dictates that a material cannot have acid erosion of more than 0.17mm.
Directions
A. CAVITY PREPARATION:
1. Clean and isolate tooth.
Note: A conservative cavity should be prepared, employing standard techniques and instruments. Undercuts are not necessary.
2. In cases where pulp protection is necessary, use a calcium hydroxide liner.
B. CONDITIONING / ETCHING:
1. Apply Riva Conditioner to the prepared surfaces and leave in cavity for 10 seconds
2. Rinse thoroughly with water
3. Remove excess water. Keep moist. Avoid contamination.
IMPORTANT: Be careful not to completely dry the surface. The surface should be glistening.
C. PROCEDURE FOR MIXING AND PLACING
CAPSULE SYSTEM:
1 Push the plunger on a hard surface until it flush with the body of the capsule. Important: Do not click with an applicator before you mix
2. Immediately place activated capsule into the Ultramat 2 amalgamator or any high-speed capsule mixer (4000 – 4800 rpm)
3. Mix for 10 seconds
NOTE: The working time can be extended by decreasing the mixing time by no more than 3 seconds (i.e. minimum mixing time is 7 seconds)
4. Immediately remove the capsule and place into the Riva capsule applicator
5. Click the trigger of the Riva capsule applicator until glass ionomer paste is seen through the clear nozzle
6. Extrude Riva Self Cure into the cavity, being careful not to trap air under the restoration.
NOTE: Temperatures higher than 23±1˚C will shorten the working time specified in the above table
7. At the end of the working time, apply Riva Coat to all exposed surfaces of restoration
8. Light cure for 10 seconds.
POWDER / LIQUID SYSTEM (REGULAR SET ONLY)
1. Gently tap Riva Self Cure powder bottle on the hand. Using the plastic scoop provided, dispense one level measure of powder onto the mixing pad
2. Carefully dispense the recommended number of drops of Riva Self Cure Liquid next to the powder on the mixing pad. Replace cap tightly
3. Use a plastic spatula and divide the powder into two equal parts
4. Mix the liquid with one part of the powder for 10 seconds and then include the second part and continue mixing for another 15 to 20 seconds
5. Place mixed paste into the cavity, being careful not to trap air under or within the restoration. At 23ºC / 74ºF, the working time will be about two minutes
6. At the end of the working time, apply Riva Coat to all exposed surfaces of restoration
7. Light cure for 10 seconds
D. FINISHING:
1. Finish the restoration using standard techniques, after the specified finishing time
2. Apply another layer of Riva Coat
3. Light cure for 10 seconds
4. Instruct patient not to eat for at least one hour after procedure.
