4. CONDENSING INSTRUMENTS •
Used to condense filling materials into the prepared cavity for better adaptation without any voids.
•
They can be hand condensing instruments or mechanical condensers.
•
Depending upon the material (amalgam, direct gold, composite) they will differ in the surface configuration of the nib-face: (smooth or serrated) and have different shapes: round, triangular or diamond and of different sizes for each shape and shank angulation. AMALGAM CONDENSER
•
Double ended, cylindrical working end with smooth or serrated face of various size and shapes, hand instruments are available.
•
Serrated face is said to increase the surface area and also to provide a mechanical interlock between the already condensed amalgam to the freshly introduced plastic mass and better adaptation to cavity and prevent spillage of amalgam.
•
With condenser of 2mm diameter the ideal condensation pressure would be 1.4 and 1.8 kg and spherical alloys requires less condensation pressure than lathe cut and admix alloy. COHESIVE GOLD CONDENSERS
•
Available as single end or double end instrument, with straight or angular shank with serrated nib.
•
Mechanical condenser are also available wherein the handpiece is adjusted so that it delivers 360-3600 blows / minute. COMPOSITE INSTRUMENTS
