Permite exhibits the best sealing qualities with no danger of excessive delayed expansion if accidentally contaminated with water-based fluids. Hence, it would seem prudent to select an alloy such as Permite for retrograde fillings. High strength, high polishability, superior handling. Permite ?the non-gamma 2 admix alloy unsurpassed by any other. High Compressive Strength ?Permite? high compressive strength minimizes the risk of fracturing the restoration. High compressive strength ensures a tough and durable long lasting restoration. Low Microleakage ?The microleakage for Permite is essentially zero. Extensive microleakage has been related to increased post operative sensitivity. Not affected by moisture INDICATIONS For the restoration of carious teeth.
