fissure bur dental
A fissure bur dental is a specialized rotary cutting instrument essential in modern dentistry, designed specifically for precise cavity preparation and detailed tooth surface modifications. These specialized tools feature a unique tapered design with spiral cutting blades that efficiently remove decay and create precise preparations in tooth structures. The bur's distinctive shape allows dentists to access narrow grooves and fissures on tooth surfaces, particularly in molars and premolars, where decay commonly occurs. Available in various sizes ranging from 0.8mm to 2.5mm, fissure burs are manufactured using high-grade stainless steel or tungsten carbide materials, ensuring durability and maintaining sharpness through multiple procedures. The cutting efficiency is enhanced by the strategic placement of flutes along the working length, enabling smooth material removal while minimizing heat generation. Modern fissure burs often incorporate advanced coatings that reduce friction and extend the tool's lifespan. These instruments are compatible with both high-speed and low-speed handpieces, offering versatility in various dental procedures, from routine cavity preparations to more complex restorative work.
