Glass Ionomer cement GLASSING contains modifiers and additives, controlling time and mechanism of paste formation.
Mixing of powder with distilled water forms a plastic paste with film thickness 12 µm. After hardening forms a cement with high biocompatibility to hard tooth tissues, sufficient strength (130 MPa) and acid erosion resistance.
Polyaclylic acid binds with dentin calcium and provides chemical adhesion and marginal fit of cement to hard tooth tissues and main construction materials. Conditioning of hard tooth tissues surfaces improves cement adhesion. Fluorine-containing glass filler is able to accumulate and release fluorine ions, thus providing prolonged anticaries effect. Aesthetic properties of material allow to use it for fixation of metal-free crowns and bridges made of high-strength ceramics.
Conditioner – is a water solution of polyacrylic acid (12 %) of blue color. Surface conditioning significantly improves adhesion and ion exchange between tooth structure and glass ionomer cement.
Radiopaque glass ionomer cement GLASSING is used for fixation of crowns, dental bridgework, inlays and onlays
Use with great care for allergic patient
As far as all terms of storing, transporting and application are observed, there are no side effects
METHOD OF USE
Shake the jar with powder before use, without turning over, tapping on palm.
1. Surface preparation (conditioning)
Prepared, cleaned and dried tooth stump should be treated with conditioner with the help of applicator (cotton ball or sponge). In 10-15 seconds clean thoroughly the cavity with water and dry slightly till glossy surface.
DO NOT OVERDRY!
Mix powder with distilled water on mixing pad or glass plate with plastic or metal spatula, at the room temperature 18-23 °C.
Comply with recommended ratio:
Ratio powder/liquid, g/ g
2 dose meter of powder spoonful / 1 drop of liquid
Mixing time, sec
Working time, min.
Hardening time from the start of mixing, min.
Higher temperature cut working time, lower temperature (for example during mixing on cooled glass plate) extend working time. Raising of ratio – powder/distilled water, cut working time. However, insufficient amount of powder worsening cement properties.
To reach optimum properties of material it is IMPORTANT TO FULFILL TEST MIXING complying with recommended by manufacturer powder/distilled water ratio.
At first mix half of measured out powder with distilled water within 10-15 seconds. Then add the rest amount of powder by portions and mix by circular motions of spatula within 20-30 seconds till plastic consistency.
For fixation, insert material into crown and fix it on prepared tooth stump without over compressing. Patient should articulate and with constant pressure wait for hardening of material. Remove excess of material.
It is recommended for patient not to eat within 2 hours.
Right after mixing clean metal instruments from material remains.
Attention! After application tightly close container with cement.
In case of eye or skin contact as well as contact with soft tissues of oral cavity, remove material immediately and wash with water.
