electromallet condenser

electromallet condenser

[-mal′ət]

Etymology: Gk, elektron + OFr, mail, maul; L, condensare, to make dense

an electromechanical device formerly used for compacting direct-filling gold, such as gold foil restorations in prepared tooth cavities.

---

condenser (knden´sur),

n (formerly called
plugger), an instrument or device used to compact or condense a restorative material into a prepared cavity. Its working end is called the
nib, or
point; the end of the nib is termed the
face. The face may be smooth or serrated.

condenser, amalgam (amalgam plugger),

n an instrument used to condense plastic amalgam.

condenser, automatic,

n See condenser, mechanical.

condenser, back-action,

n a condenser with the shank bent into a U shape so that the condensing force is a pulling motion rather than the usual pushing force.

condenser, bayonet,

n a condenser in which the offset of the nib and the approximately right-angled bends in the shank permit a better line of force for condensation of direct filling gold. There are many variations in angles, length, and diameter of the nib.

condenser, electromallet (McShirley's electromallet),

n an electromechanical device for compacting direct filling gold. Frequency of blows may be varied from 200 to 3600 strokes/min; the intensity of the blow is controlled electronically.

condenser, foil,

n a condenser used to compact direct-filling gold.

condenser, foot,

n a foil condenser with the nib shaped like a foot.

condenser, hand,

n an instrument that compacts material, the force being applied by the muscular effort of the clinician with or without supplementary force from a mallet in the hand of the assistant.

condenser, Hollenback,

n.pr See condenser, pneumatic.

condenser, long-handled foil,

n a hand condenser of varied design for compacting gold foil.

condenser, mechanical,

n (automatic mallet), a device to supply an automatically controlled blow for condensing restorative material. It may be spring activated, pneumatic, or electronically controlled.

condenser, parallelogram

n a condenser the face of which is shaped like a rectangle or parallelogram.

condenser, pneumatic (Hollenback condenser)

n a pneumatic mechanical device developed by George M. Hollenback to supply a compacting force. The force is delivered by controlled pneumatic pressure. Blows are variable in intensity, with speed variable up to 300 strokes/min.

condenser point,

n See point, condenser.

condenser, round,

n a condenser the face of which has a circular outline.

condenser, stepping,

n the orderly movement of a condenser point over the surface of gold foil or amalgam during its placement and compaction.
