1.General: Glass Ionomer Cement developed for cementing teeth as a base. Of all the composite restoratives, Glass Ionomer is one of the prettiest restorations available.These restorations not only look good, but also bond to tooth structure quiet well.
2. Used for the cementation of crowns , bridges, inlays and the restorative filling of classⅢ、IV cavities, the cement is highly bio-compatible, not irritated to mouth tissues,insoluble in oral cavity and good in marginal seal.
3. Procedure:
One clean, dry glass mixing slab at room temperature (70-77°F /21-25 ℃ and humidity of 50±10%).
A stainless steel spatula free of dust, set cement and moisture.
Powder and liquid prorate:
use as a cement: 2.7g : 1g
use as a base: 2.3g : 1g
Mixing technique: Place measured powder on the slab and formed into two portions.Add half of the powder into
placed liquid and mix them in 10 seconds, add the other half of powder. Whole mixing time should be less than 30
seconds. Total working time should be 1.45 minutes.
3. Data:
Solidifying time: 1.5~6 minutes.
Compressive strength: ≥90Mpa.
Acid-erosion: ≤0.17 mm.
When cement is going to be solidified, it will be too soft to do filing and polishing.Polishing can be done only after
24 hours.
Polishing way: use light press and high speed.
4. Storage: Store in a dark and dry place.
5. Effective date: 3 year

CHARACTERISTICS
Glass Ionomer Cement has many advantages, such as high compressive strength, low polymerization heat.low polymerization expansion coefficient and good transparence. Moreover, this cement is stable, not irritant to mouth tissues, insoluble in oral cavity and good in marginal seal. This product has three colors fol you to choose which matches the color of natural teeth perfectly. With finer powder and higher compressive strength, the dental cement is good enough to ensure your patients' health of oral cavity.
USAGE
Mainly used in bases and lining of cavity
PROCEDURE
•Mixing it on the glass plate with an agate or plastic spatula.
•Environment of mixing: using at the temperature of (23±1) °C and at the relative humidity of (50±10) %recommended. If using it at higher temperature, its set procedure will be fastened and its work time will be decreased. If using it at warmer area, please use a cooler glass plate.
•The proportion of powder to liquid is 2.0g:1.0g.
•The proportion of powder to liquid for test is 2.0g:1.0g. Test at the temperature of (23±1) °C and at the relative humidity of (50±10) % in accordance with ISO 9917-1:2007.
•Permeation rate of powder/liquid:
When mixing, first shake the powder in a glass bottle loose, secondly take out powder with a spoon to slight overfill its surface, and then strike off the excess with a spatula and pour it on a mixing paper plate. Finally set a bottle of special liquid upside down vertically, bring its mouth of the bottle about 5mm to the mixing paper plate and extrude two drops of special liquid carefully and slowly. If bubbling up, the bottle will be set upside down and tapped gently so as to allow the bubble to leave away its mouth.
Divide the weighed powder into three heaps of equivalents, then put the first heap of powder into proportional liquid and mix it evenly for about 10 seconds, and put the second heap of powder into proportional liquid and mix it evenly for about 15 seconds, then put the last heap of powder into proportional liquid and mix it thoroughly.
•Mixing time: accomplish the whole mixing procedure within 60 seconds.
•Work time: accomplish at 90 seconds after commencement of mixing of the material.
•Before using, you must dispose of the facing and prosthesis tissue surface by cleaning, disinfecting and drying. It must not be re-polluted by saliva.
•Post treatment: after filling and fixing, remove the excess material with a wet cotton wool and trim at 24h after setting immediately.
MAIN TECHNICAL DATA
•Net setting time: 1.5~6 min
•Compressive strength: ≥50 MPa
•Acid-erosion: ≤0.17 mm
STORAGE
Store in a dark and dry place.
SHELF-LIFE
Two years
CAUTIONS
•Don't use metallic spatula or else, it would change the cement liquid color.
•In order to avoid the influence on its properties, please wring the lid of bottle tightly at once after using it.
WARNING
•Prevent it from splashing into the eyes. If it is splashed into the eyes, immediately flush the eyes with plenty of clean water, and then see a doctor.
•Put it in a dry place and keep away from children.
