Glass Ionomer Dental Luting Cement

● Cementation of stainless steel or metal-porcelain crowns, bridges, posts and screws.

● Cementation of all ceramic (zirconia-based) crowns and bridges.

● Cementation of orthodontic parts to metal crowns, and orthodontic bands.

● Base and bottom.

● Fine and smooth powder is easy to mix, and the mixed material has excellent fluidity.

● Thin film thickness (<18µm ) is convenient for restoration in place.

● Good adhesion to tooth tissue and restoration with good edge sealing effect.

● Good biocompatibility and coefficient of thermal expansion similar to tooth tissue reduce postoperative sensitivity.

● Easy to operate, ample working time, fast intraoral curing speed and low solubility.

● Long-term fluorine release and anti-caries effect.

1. Product Description  1. 产品描述
The dental glass ionomer cement for manual mixing is easy to mix and prepare. The material which is chemically bonded to enamel and dentin provides excellent adhesion properties and sealing of margins of fillings. It releases fluoride ions, and is radio-opaque.
用于手动混合的牙科玻璃离子体胶水混合和准备非常简单。这种化学结合于牙釉质和牙本质的材料，具有优异的粘附性和填充物边缘的密封性。它释放氟离子，且是放射不透明的。

5. Cautions
It cannot cover the pulp directly.
It contains polyacrylic acid and tartaric acid, please do not use in case of known hypersensitivity to these ingredients.
In case of eye contact, rinse immediately by clean water and seek medical treatment.

6. Method of use

Preparation
Thoroughly clean and dry the surfaces of the tooth and restoration to be cemented. 
Clean cores before luting, rinse and dry with water and oil-free air or dab dry with cotton pellets. Do not over-dry!
Avoid further contamination by saliva.

Pulp Protection
The glass ionomer cement must not be applied directly to dentin. E.g. on inlays - situated close to the pulp or to the exposed pulp.
Prior to taking the impression, cover areas close to the pulp using a hardsetting calcium hydroxide.

Dosage
Shake bottle to loosen powder.
The recommended powder-to-liquid mixing ratio is 2~2.5:1 (w/w), this corresponding to 1 level spoonful of powder to one drop of liquid. Do not compress the powder.
If the mixture is too thin (due to insufficient dosing of powder) this may produce symptoms of pulpitis.

Mixing
Mix GIC using a plastic cement spatula at the a room temperature of 20-25℃/68-77℉.
Add the powder to the liquid in one portion. On principle a sufficient quantity of powder should be added to the liquid to produce viscid consistency.
Continue to smooth out the paste until a homogeneous mixture is obtained.

Application
During application, water and saliva must be prevented from entering the working area.
Apply a thin coat of cement to the surface of the restoration to be cemented and to the preparation.

Subsequently seat the restoration.
Avoid overfilling the restoration. Applying hydrostatic pressure buildup in tightly fitting restorations may cause pulp discomfort.

Times
The following time scale applies at a room temperature of 23-26 ℃ and 50% relative humidity:

Higher temperatures shorten the working time, whereas lower temperatures will extend this period. A higher amount of powder also brings about a shorter working time. Exceeding the working time causes loss of adhesion to enamel and dentine.
温度越高，工作时间越短，温度越低，工作时间越长。粉末量越多，工作时间也越短。超过工作时间会导致牙釉质和牙本质的附着力丧失。

Removal of Excess  去除多余部分
Remove excess and remove any cement residues still remaining in the sulcus of the treated teeth and the surrounding areas.
去除多余的牙关，并清除治疗牙齿沟槽及周围区域中残留的水泥残留物。

7. Storage and Shelf-Time
Keep the powder in a dry place away from damp.
Store the product at 4-25℃/39.2-77℉.
Do not use after the expiry date.
