DENTSPLY Megalloy EZ Instrucciones De Uso página 2

8. STEP-BY-STEP INSTRUCTIONS
1. Treatment of the preparation: Clean freshly instrumented enamel and dentin with water
spray and then air dry. The use of pulpal protection, bases and/or cavity liners is at the
discretion of the operator, as dictated by the clinical presentation. If desired, Megalloy
Amalgam may be placed over an adhesive liner or adhesively bonded by following the
manufacturer's instructions for compatible adhesive systems (available separately).
2. Trituration: Simply place Megalloy ®
amalgamator. These capsules are activated by the amalgamator – they do not require manual
activation. Trituration speed and time is an important factor in preparing the amalgam, in
order to achieve proper amalgam mix consistency. The chart that follows provides guidelines
in determining amalgamator trituration time and speed setting for Megalloy

Suggestions for obtaining optimum mix
2.1 The triturated amalgam should be bright and have a plastic consistency. If the amalgam
is excessively splashy and wet looking, INCREASE trituration time or amalgamator
speed. Amalgam that appears excessively dry indicates trituration time or amalgamator
speed should be DECREASED. Slow speed amalgamators are not recommended.
2.2 When performing adjustments, it is recommended to adjust trituration time in 2 second
increments, until optimum mix is obtained. Greater adjustments may indicate
amalgamator incompatibility or compromised functionality.
Decrease trituration time:
- To lengthen working time
- If mix is too hot
- If mix is too dry
2.3 Properly triturated Megalloy ® EZ Amalgam does not require mulling to produce a smooth
plasticity; however you may mull for 1-2 seconds after removing pestle to collect
amalgam into a single mass.

3. Condensation
3.1 No tool is needed to open the Self-Activating capsule. Just grasp both ends of the
capsule, twist, and pull apart. Turn the opened capsule upside down to drop the

placement and condensation. A gentle tap may be required to free amalgam from the
capsule. Do not attempt to manually express mercury from the triturated mass prior to
placement.
3.2 A plastic wafer and/or plastic mixing pestle may be seen. These have no further function
and should be properly recycled.
3.3 Condense immediately after mix is completed. Use a clean amalgam carrier to transfer
increments to the cavity. Pack each increment into angles and undercuts with small-

faced plugger and sufficient pressure to insure good adaptation. Build the restoration
with additional portions, until the cavity is slightly overfilled. Remove any mercury-rich
amalgam from the surface that may develop during condensation.
4. Carving/Burnishing: Carving can begin immediately after condensation. A sharp carver will

give best results. The anatomy should be carved proceeding from the proximal margins

towards the center of the restoration. Before the matrix band is removed, the marginal ridge
should be supported by a condenser. After removal of the matrix band, gingival margins may
