Study Notes

Condensation in Alloy Dentistry

Goal of condensation: Compact the alloy into a cavity for maximum density with sufficient mercury for matrix continuity between alloy particles.
Importance of reducing excess mercury and porosity in the amalgam sets.
Alloy increments should be introduced into the cavity using small forceps or an amalgam carrier.

Condensation Procedure

Condensation involves pressing a condenser point onto the amalgam mass using hand pressure; starts at the center and progresses to cavity walls.
Required force varies depending on the alloy particle shape.
A shiny surface post-condensation indicates adequate mercury presence for diffusion into the next increment, ensuring a solid bond.
Removal of excess soft material before adding new increments is recommended, but less critical with modern amalgams requiring less mercury.
In large cavities or prolonged condensation procedures, refresh the mix before the previous one loses plasticity to avoid complications.

Challenges and Recommendations

Condensation of partially set material can fracture the already formed matrix, leading to internal voids.
Loss of plasticity in the alloy complicates further condensation efforts, emphasizing timely execution.
Continue the process until the cavity is overfilled to ensure sufficient material density and integrity.
