Instructions To Use
Prepare cavity using standard technique for amalgam restoration.
Note: In cases where pulp protection is necessary, use a calcium hydroxide liner or glass ionomer cement.
Activate a capsule on a bench or hard surface until plunger is fully flushed with the body of the capsule.
Place activated capsule in a high speed multi-use triturator.
Carefully remove the triturated capsule from the triturator and gently tap the base on a bench or hard surface once.
Open the capsule by removing the base from the body to access the prepared amalgam.
Note: Freshly mixed amalgam should have a bright look and a plastic consistency.
Immediately insert amalgam into prepared cavity using a clean amalgam carrier employing standard amalgam condensation technique.
i. “If moisture is introduced into the dental amalgam before it has set, properties such as strength and corrosion resistance can be affected adversely. If the alloy contains zinc, such contamination can result in excessive expansion (delayed expansion). Use a dry field, whenever it is possible.
ii. Permite contains zinc in an alloyed form and not free zinc. It’s the free zinc which is very sensitive to moisture.
Remove any mercury rich amalgam from the surface that may develop during condensation.
Trimming and carving can begin after condensation using a sharp carver.
Light burnishing can be carried out after 24 hours to improve surface smoothness. Avoid over heating by ensuring adequate water cooling and low speed.
