ROCK HILL, South Carolina--KOMET USA will introduce its new Carbide Crown Prepping Instruments during this year's Greater New York Dental Meeting in New York City.
According to Donald Alexander from KOMET USA, the Carbide Crown Prepping Instruments are superior to previous prepping instruments because they allow for precise and controlled tooth reduction while providing a finished surface comparable to that achieved by using a diamond finisher.
Designed by Donald J. Alexander, DDS, of Jacksonville, Fla., the instruments provide real quick and smooth chatter free cut patterns. The residual finish allows for both gross and finish work to be accomplished using the same instrument.
The flat-ended bur H837KRU--available in two sizes--is ideally designed for crown preparations that use a porcelain-butt margin. The round-ended bur H881U is more suited to create a chamfer for Alumina or Zirconia CAD/CAM copings.
The cutting surface of both forms of the Carbide Crown Prepping Instruments are the same as KOMET USA's H4MCL bur which has a special D-toothing for quick and efficient cutting of crowns and bridges made of conventional metal alloys.
Because of the cylindrical form of the new Carbide Crown Prepping Instruments, the cutting depth is a known quantity removing the need for depth grooves, with a cutting depth of 1.2 mm for the parallel chamfer form H881U.FG.012, a cutting depth of 1.4 mm for the modified parallel shoulder H837KRU.FG.014 and 1.6 mm for H837KRU.FG.016.
Also, the tips were engineered to match up precisely with the required chamfer or shoulder prep design depending on the desired material.
The instruments allow for a fast and precise controlled tooth reduction resulting in a finished surface much better than one completed with a super coarse diamond instrument. The finish left by these prepping instruments is so good; that there is no need for an additional finishing instrument.
The Greater New York Dental Meeting will be held Nov. 23-28 at the Jacob K. Javits Convention Hall in New York City. The new Carbide Crown Prepping Instruments will be for sale at the show. Visit KOMET USA at Booth #436.
