amalgam condenser

amalgam condenser,

a dental instrument used for compacting silver amalgam while in a plastic state, used for restoring teeth to a natural contour.

amalgam (mal´gm),

n (dental amalgam alloy), an alloy, one of the constituents of which is mercury.

amalgam, bonded,

n 1. a composite of tooth-colored acrylic resin and finely ground glass-like particles that is bonded or adhered to the tooth during dental restoration. The advantage is that less of the tooth structure needs to be removed during the restoration, resulting in a smaller filling compared with traditional amalgams.
2. a composite filling.

amalgam carrier,

n See carrier, amalgam.

amalgam carver,

n See carver, amalgam.

amalgam condenser,

n See condenser, amalgam.

amalgam, copper,

n an alloy composed principally of copper and mercury. See also amalgam.

amalgam, dental,

n an amalgam used for dental restorations and dyes.

amalgam matrix,

n See matrix, amalgam.

amalgam pigmentation,

n See amalgam tattoo.

amalgam plugger,

n See condenser, amalgam.

amalgam, silver,

n a dental amalgam, the main constituent of which is silver. The ADA composition specifications are as follows: silver, 65% minimum; tin, 25% minimum; copper, 6% maximum; zinc, 2% maximum.

amalgam squeeze cloth,

n a piece of linen used to hold plastic amalgam from which excess mercury is to be squeezed. Used with hand trituration.

amalgam tattoo,

n a solitary discrete gray, blue, or black discoloration of tissue usually located in the gingiva, alveolar ridge, or buccal mucosa caused by small amounts of dental amalgam that became embedded under the surface. The asymptomatic lesion is static and requires no treatment. If doubt exists about the lesion or if the lesion is unsightly, excisional biopsy is recommended.

Amalgam tattoo.

amalgam well,

n a small, bowl-shaped container that holds mixed amalgam prior to its being loaded into the amalgam carrier.

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.
