Dental burs are a necessary component of routine general dental procedures. The rotary tools come in a variety of sizes, forms, and grits and are made to cut hard tissues like bone or tooth enamel. They have several cutting edges and two or more sharp-edge blades.
Traditionally employed as simple cutting tools for tooth restoration preparation, science and technology have propelled the development of the common bur to unprecedented heights, offering a vast array of alternatives for performing a wide range of dental operations.
Dental burs are composed of steel, stainless steel, tungsten carbide, and diamond grit. They are quickly sturdy and of excellent quality.
1. The rotating blade that cuts tissue is located in the head.
2. The head, which houses the Bur or the cutting blade, is joined to the neck.
3. The bur piece's shank is its longest section. It can be attached to many handpiece kinds with its various ends.
Long straight/handpiece burs (HP): These burs have a longer, straighter shank and are designed for handpieces with slower speeds.
Right angle (RA)/latch-type: These attach to low speed contra-angle handpieces.
FGs, or friction grips, are utilised with high-speed handpieces.
They are typically categorised by shape—cone, round, or spear—and are utilised with high-speed handpieces. The head shape, the abrasiveness of the grit, and the angle and placement of the blade are the distinctive qualities that help determine which bur is best.
1. Round burs - excellent for clearing away substantial dental decay, preparing cavities, excavating, and establishing channels and access points for blades during dental extractions.
2. Flat-end Burs: rotational intraoral tooth preparation and correction, removal of tooth structure.
3. Pear burs: these tools make an undercut that is used for finishing, excavating, filling materials, and trimming.
4. Cross-cut Tapered Fissure: This type of fissure is perfect for exact preparations while preventing debris buildup, as in crown work.
5. Restorations are completed with the use of finishing burs.
Burs are available in several coarseness grades, just like sandpaper. To put it simply, the abrasiveness varies to fit various tasks. More tooth surface will be removed with coarser grit. The job that demands finite detail, like smoothing around margins or rough edges, is best suited for finer grits.
Dentists have access to a wide variety of burs, and choosing the best one can greatly enhance clinical casework. This should ideally be accomplished during the treatment planning phase.
1. Sterile Diamond Burst: Utilising high-quality diamonds for dependable cutting that can be reused again, these bursts are pre-sterilized for instant usage.
2. Gold Diamond Bursts: Featuring a comprehensive array of popular sizes and shapes, these bursts are crafted with the finest Swiss-made steel shanks. They provide great performance and are robust and long-lasting.
3. Twister Diamond Bursts: With a precision-engineered head for quickest operation and least resistance, these natural diamond-coated bursts deliver non-clogging spiral dual action. Perfect for a seamless finish and quick bulk reduction.
4.Steel Burs: Made from heat-treatable alloy steels for maximum strength and dependability, these burs are intended for low vibration, which can cause handpiece breakage and patient discomfort.
5. Tungsten Carbide Burs: These are extremely sharp and effective cutting tools. They are made of strong material. They provide a quick, fluid, vibration-free operation that reduces operating time and improves patient comfort.
1. Surgical Burs: Today's surgical burs are typically made of diamond or tungsten carbide, which makes them robust, long-lasting, and highly effective in oral surgery.
2. Diamond burs are typically employed with high-speed handpieces to give a rough finish. They are used to cut through porcelain and grind away tooth tissue.
3. The optimal strength, durability, and performance are also designed into Tungsten Carbide Bursts. These teeth structures are polished to a fine finish and are three times tougher than steel.
4. Restoration Burs: To remove porcelain restorative material, diamond burs work effectively.
5. Tungsten Carbide Bursts are a useful tool for trimming and polishing composites, as well as for chipping away at the tooth structure to remove metal restorations. They can be used to shape bone, remove old filling material, and excavate and prepare cavities for fillings. They can also be utilised to separate crowns and bridges and remove impacted teeth.Compared to a Diamond Bur, they leave a smoother surface.
6.Ceramic burs are perfect for preparing cavities and removing dentin.
7. Amalgam restorations are removed using cylindrical burs.
8. Finishing Burs are intended to give restorations the last touches, such as shape and finer detail.
9. Intraoral tooth preparation is done with flat-end cylinder burs.
10. Inverted cone burs can be used to undercut access openings for restorations or root canal therapy. Additionally, they can be used to flatten gingival or pulpal walls.
11. For intraoral tooth preparation and adjustment, round-end taper burs are utilised.
12. Steel burs are the best tool for removing dentine and preparing cavities.
13. Orthodontic Burs: For interproximal reduction, de-bonding, and consistent, safe resin removal with little harm to tooth enamel, as well as for subsequent enamel polishing, a Tungsten Carbide Bur in a contra-angle handpiece can be utilised.
14. Laboratory Burs: For modifying thermoplastics and acrylic, ceramic burs are the best option.
15. Steel Burs are made to work with acrylic materials, such bespoke trays and dentures. They withstand abrasion and have good edge retention.
