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’s 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.
Features:
- High Compressive Strength
Permite’s high compressive strength minimizes the risk of fracturing the restoration. High compressive strength ensures a tough and durable long lasting restoration.
The microleakage for Permite is essentially zero.
Extensive microleakage has been related to increased post operative sensitivity
- Optimal handling characteristics
In the Dental Advisor Plus Permite received a 98% rating for consistency of mix, ease of loading, placement in preparations, condensability, burnishability, quality of interproximal contact, carvability and setting characteristics. The resulting restorations are smooth and have excellent margin adaptation, especially after burnishing. All consultants said they would recommend Permite to their colleagues.
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.
- Greater choice of setting times and larger choice of capsule sizes
The working and setting times allow large restorations to be condensed and carved without difficulty.

Warnings
- Harmful if vapours are inhaled.
- Avoid breathing vapours.
- Harmful if swallowed.
- Use with adequate ventilation
- Single-use only
- For professional use only
CAUTION: Federal law restricts this device to sale by or on the order of a dentist.
- Keep out of reach of children
- Do not open capsules prior to trituration
- Do not remove the coloured plunger from the capsule.
- Effect of mercury on metals: Mercury reacts with and embrittles particular metals and their alloys. Avoid unnecessary contact between mercury and those metals (and their alloys).
- The wearing of gloves, glasses and protective clothing is recommended for all dental procedures
- Do not eat, drink or smoke when using this product
- Follow good safety clinical practices when performing amalgam restorations.
- Always keep unused product in original, labelled container and store in temperatures below 25˚C / 77˚F in a cool, well-ventilated area.
- Existing studies indicate that some people with amalgam restorations may be sensitive to prolonged close encounter with sources of electromagnetic radiation, ie mobile phone. In patients hypersensitive to amalgam, existing amalgam restorations should be replaced with an alternative material.
- Some patients may experience a metallic taste post restoration especially when placed in close contact with other metal restorations due to galvanic effect. If this persists, consider replacing with an alternative material.
- Dispose of used capsules in accordance to national regulations.

Direction To Use:
STEP 1:
STEP 2:
- 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.
STEP 3:
- Activate a capsule on a bench or hard surface until plunger is fully flushed with the body of the capsule.
STEP 4:
- Place activated capsule in a high speed multi-use triturator.
STEP 5:
- Triturate capsule as per recommended in Table below.

STEP 6:
- Carefully remove the triturated capsule from the triturator and gently tap the base on a bench or hard surface once.
STEP 7:
- 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.
STEP 8:
- Immediately insert amalgam into prepared cavity using a clean amalgam carrier employing standard amalgam condensation technique.
Note:
- 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.
STEP 9:
- Remove any mercury rich amalgam from the surface that may develop during condensation.
STEP 10:
- Trimming and carving can begin after condensation using a sharp carver.
STEP 11:
- Light burnishing can be carried out after 24 hours to improve surface smoothness. Avoid over heating by ensuring adequate water cooling and low speed.
