pneumatic condenser

pneumatic condenser

Etymology: Gk, pneuma, air; L, condensare, to thicken

a pneumatic device that delivers compacting blows of variable force to restorative material used in filling tooth cavities. The frequency of the blows may be up to 360 per minute. Also called Hollenback condenser.

---

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.
