pyrax cavityfil silver alloy – 50 capsules
The technically advanced PRE DOSED NON GAMMA 2 FINE GRAIN 48% AMALGAM POWDER, with High Strength ensures longevity and patient satisfaction. The alloy to mercury ratio 1:1 ready for mixing on a amalgamator. The compressive strength of PYRAX CAVITYFIL at 24 hours is 510 MPa, and the dimensional change during hardening is +0.02%.
Optimal handling characteristics PYRAX CAVITYFIL consistent mix, ease of loading, placement in preparations, condensability, burnishability, quality of interproximal contact, carvability, and setting characteristics ensure the final restorations meet the needs of the EXCELLENT DENTISTRY.
High compressive strength PYRAX CAVITYFIL 510 Mpa high compressive strength minimizes the risk of fracturing the restoration. High compressive strength ensures a tough and durable long lasting restoration.
Positive dimensional change PYRAX CAVITYFIL positive dimensional change ensures excellent sealing qualities at the margins. Capsule system The PYRAX CAVITYFIL capsule system is designed to give consistent and accurate mixes every mix. 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.
Instructions for Use
- Select the appropriate size PYRAX CAVITYFIL AMALGAM capsule according to color coding WHITE , YELLOW, BUE , RED.
- 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 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. It is not necessary to express mercury prior to insertion. Traditional condensation techniques are recommended. Pack angles and undercuts with a small-faced plugger, using sufficient pressure to ensure good adaptation. 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 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. Avoid overheating by ensuring adequate water cooling and low speed polishing.
