Tungsten carbide burs are used most commonly for excavating and preparing cavities, finishing cavity walls, finishing restoration surfaces, drilling old fillings, finishing crown preparations, contouring bone, removing impacted teeth, and separating crowns and bridges. Carbide burs are defined by their shank and by their head. The type of handpiece being used determines which type of shank is needed. The procedure to be performed determines the type of head shape that is chosen.
Tungsten carbide burs also be used to trim and finish macro-filled composites and hybrid composites.
Tungsten carbide burs slice or chip away at material, leaving the tooth surface smooth and more aesthetically pleasing.
• For use in high speed handpieces.
• Has the smallest diameter shank of all the types of carbide burs; the end of the shank is smooth and is held in place in the handpiece by friction against a chuck.
• The most commonly used operative bur in many offices.
• For use in high speed handpieces (with miniature heads ONLY)
• Has a shank that is the same diameter as a standard friction grip bur but is almost 20% shorter; also held in place in the handpiece by friction.
• For use when better access to the posterior region is needed, especially when patients cannot open their mouths wide enough.
• For use in high speed handpieces and friction grip low speed contra angle heads.
• Has a shank that is the same diameter as a standard friction grip bur, but the total length of the shank and head is about 30% longer; also held in place in the handpiece by friction.
• For use in latch-type contra angle heads in low speed handpieces.
• Has a notch on the end that allows a hook to latch onto it in the head of the handpiece.
• Provides greater control when cutting dentin or enamel.
• For use in latch-type contra angle heads in low speed handpieces.
• Has a notch on the end that allows a hook to latch on to it in the head of the handpiece.
• Has a shank that is the same diameter as a standard right angle bur but is about 20% longer.
