Q1.Why is iGOS-BOND required to be left for 20 seconds after the application?
Generally, hydroxyapatite of the surface of tooth substance is demineralized by adhesive, then adhesive osmoses into etched surface of it during being left after the application. iGOS-BOND requires 20 seconds to leave for effective etching of surface of it.
The adhesive performance will decrease if demineralization and osmosis were not performed appropriately.
Q2.What is the thickness of the iGOS-BOND coat after irradiation?
It is approx. 10- 30 μm.
In case of iGOS-BOND, inhibition of adhesive by oxygen is not caused easily and iGOS-BOND has excellent curability. But we think it is better to leave the unpolymerized surface as adherent since unpolymerized surface enables CR and adhesive to adhere with each other strongly.
Unpolymerized surface is necessary to be adhered to CR. Oxygen inhibition is one of the main reasons for uncuring. You may think it will be difficult to get good adhesive condition if oxygen inhibition is difficult to happen. However, excess of existence of unpolymerized area by the inhibition will reduce the strength, so it should be minimized. This adhesive offers good bonding conditions thanks to excellent ability to be cured and the characteristics to leave uncured surface to a necessity minimum.
Q3.How many milligram is iGOS-BOND per drop? How many drops can be taken out from one bottle?
It is 19- 20 mg in one drop of iGOS-BOND. It is 200 drops by one bottle at least.
Q4. In cases of fracture of CR in the oral cavity, what application should I use to repair?
After cleaning with a dental-etching material (Multi-Etchant, etc.,) apply Multi Primer Liquid and iGOS-BOND then light cure. After light curing, repair with CR.
Q5.Why can Multi Primer Liquid be used for most dental restorative materials?
Multi Primer Liquid can be used for most dental restorative materials thanks to the synergistic effect of each component of polythiol compound and silane coupling reagent.
Q6.Is it OK to storage Multi Primer Liquid and iGOS-BOND together in a refrigerator?
There is no problem. Please use them after bringing them back to normal temperature.
Q7.Does Multi Primer Liquid have function of adhesive to tooth substances?
No it doesn't have function of adhesive.
Q8.Is there any data of the adhesive strength?
The adhesive strength is shown in the product catalog.
