Composition of material, form of release
Units is a zinc oxide with various impurities, the whole mixtureis placed in orthophosphoric acid with little activity. It looks ready, as a material resembling a film with a thickness of not more than 25 microns.
Thanks to the active silver in the bactericidal material, the development of caries is prevented. It is, as a disease of milk teeth, and permanent.
The material is available in two forms: 
- powder of a certain color, liquid in the can, device for measuring the required dose of material, lid with a drip hole, instruction;
- bactericidal powder, liquid in the can, device for measuring the required amount of the product, cap with a drip hole, instruction.
The amount of colored powder in the jar can be 50 or 100 g, and the liquid, respectively, 30 or 60 g. Bactericidal Unitsem is produced exclusively as a kit, which includes 50 g of powder and 30 g of liquid.
The material fully complies with GOST standards.
The properties of
Cement is characterized by maximum stability when exposed to the environment. How strong cement will be, directly depends on the concentration of the powder in the solution.
The new material is versatile. The strength of cement is determined by direct mechanical action, it can withstand the compression pressure from 90 to 121 MPa, and this depends on the ratio of liquid to powder.
Scope of application
Unitsem is used for the following purposes: 
- for fixing crowns from various materials, pins, inlays, bridges;
- when sealed;
- as an insulating seal;
- bactericidal material is intended for filling of milk teeth.
Instruction for use
Application of the material is carried out exclusively by professionals who not only determine the required ratio of the solution, but also independently dilute it.
Units is widely used for fixing crowns from various materials: metal, plastic, ceramics, cermets, porcelain.
Before direct use of the preparation that has been transported or stored at low temperatures, leave the material for at least one hour in a warm room to reach room temperature.
Thanks to the dropper, which is included in each kit, it is easy to dose the liquid. For the convenience of the dosage of the powder, there is also a special device in the kit.
Mixing takes place on a glass surface so that a simple and chiseled spatula is needed to mix it easily and efficiently. The temperature, which is the most optimal for mixing, should not exceed 23 ° C.
Attention should also be paid to the relative humidity in the room, which should not reach 60%.If for some reason, the room temperature exceeds the permissible value, it is recommended to rinse the glass surface for mixing with cold water first or hold it for a couple of minutes in the refrigerator.
The peculiarity is that the mixing of the required amount of solution occurs gradually, twice, each half of the required volume.
The duration of the pasting process should not exceed one minute. To fix the ratio of powder to liquid should be 1.5 to 1, and for sealing 2 to 1.
Application as a fixator
The correctly prepared solution resembles sour cream. The finished mass remains plastic for no more than 2.5 minutes.
Therefore, it is so important that the solution does not have time to harden on the glass surface before it is directly applied. In the mouth, the solution hardens in 8 minutes.
Use when sealing
The properly prepared solution should be thick. The plasticity of the finished mass is maintained for no longer than 1.5 minutes while on the glass plate. In the oral cavity the solution will harden after 6 minutes.
Filling of the tooth provides for its complete isolation from saliva. The treatment of the cavity should be carried out with a cotton swab, which has been previously moistened with anhydrin.
As drying, it is best to use a warm air stream, it is forbidden to use ethyl alcohol for this purpose.
Analogues and cost
The price of Unitsem cement varies from 100 to 200 rubles, fluctuations in cost depend on the region and the sales network.
