Waldent WalCap Amalgam Capsules feature a high-copper alloy with admix particles, offering superior sealing qualities and minimal risk of delayed expansion if inadvertently exposed to water-based fluids. Therefore, choosing an alloy like WalCap for retrograde fillings is a prudent decision. The capsules are pre-dosed and self-activating for convenience.
Advantages :
- High Compressive Strength – WalCap’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 WalCap is essentially zero. Extensive microleakage has been related to increased post operative sensitivity. Not affected by moisture.
- Optimal handling characteristics - WalCap's consistency of mix, ease of loading, placement in preparations, condensability, burnishability, quality of interproximal contact, carvability and setting characteristics are excellent. The resulting restorations are smooth and have excellent margin adaptation, especially after burnishing.
Indications :
- Stress bearing fillings in posterior teeth (Class I and II).
- Retrograde root canal filling after apex resection.

Driection to Use
- With the capsule inverted, SLOWLY press the plunger end of the capsule against a flat surface until the flange of the plunger is flush with the capsule body
- THIS IS MOST IMPORTANT. Initially, resistance will be felt, then suddenly released as the plunger pierces a diaphragm allowing the mercury to enter the mixing chamber
- Slightly spread the amalgamator (EndoKing Amalgamator For Amalgam and GIC) clips and carefully insert the capsule. Ensure that the capsule is securely anchored between the clips
- Select the appropriate mixing time from the suggested mixing times A range of mixing times is given to accommodate mixing variations that can occur due to machine type, age and line voltage. Correctly triturated amalgam will form into a bright homogeneous plastic mass. A hot, shiny, sticky mass indicates over trituration whilst a dull, dry or powdery mass is under triturated
- After trituration has been completed, carefully remove the capsule from the clip
- Tap the base end of the capsule sharply on the bench to ensure that the mixed amalgam is located in the base of the capsule
- Separate the base from the body and remove the prepared amalgam from the capsule. If the small separating diaphragm has come away from the capsule wall during activation and mixing, it will separate cleanly from the amalgam
CONDENSATION: Moisture contamination: If moisture has introduced into the amalgam before it has set, properties such as strength and corrosion resistance may be affected adversely. If the alloy contains zinc, such contamination may result in an excessive expansion (delayed expansion). Whenever it is possible, use a dry field. Insertion of the amalgam should commence immediately after trituration. Build the restoration with additional portions until cavity is slightly over filled. Remove any mercury rich amalgam from the surface, that may develop during condensation
FINISHING: Trimming and carving can be commenced immediately after condensation has been completed. Light burnishing can be used to advantage and if the restoration is polished, this procedure should be carried out after 24 hours.
