The diamond-coated options are popular because they assist in quicker and neater cuts, especially when dealing with porcelain or composite materials in current dentistry.

  • Tapered Fissure Burs

    Tapered fissure burs are highly valuable in making angled grooves and fissures in the cavity walls. Their tapered shape provides better control when shaping the cavity and aids the dentist in creating ideal retentive forms for fillings. Tapered fissures are accessible in different sizes and are widely employed in restorative practices.

  • Round Burs

    Round burs are basically employed for drilling holes and removing decayed tissue from inside the teeth. This is one of the most normal types of burs used in dental carborundum burs due to their flexibility. Files marked with the "A" or "AA" suffix usually have carbide tips, while diamond burs provide a smoother finish.

  • Flat Burs

    Flat burs, also recognized as straight fissure burs, are employed to make sizeable and flat cavities in the tooth. This bur type is important in cavity preparation, as it helps create an even surface for the appropriate placement of fillings. Flat burs are available in carborundum, stainless steel, and tungsten carbide.

  • Pearl-shaped Burs

    Pearl-shaped burs are mainly used for excavating and purging dental caries. Its shape helps in making wider cavities with rounded edges, facilitating better retention of restorative substances. It can be diamond-coated or in carborundum, suited for distinct applications.

    Carborundum burs are often engraved in orthodontic practices in adjustments to wires and braces. Their strength and versatility allow them to easily cut through several orthodontic materials such as stainless steel and nickel-titanium alloys. This provides the orthodontist with an effective tool for rendering precise adjustments to gear. Therefore, ensuring that patients receive the required ideal level of treatment.

Product specifications and features of dental carborundum burs

Key Features

  • Versatility: Carborundum burs come in different shapes and grits to allow them to be used for cutting and polishing. This makes them of great importance in restorative and prosthetic dentistry.
  • Durability: These are extremely durable, which is a good quality since they carry out heavy-duty work in clinical operations. Carborundum has a higher abrasion resistance ability than steel, which means it will not wear out or break quickly.
  • Precision Cutting: Carborundum burs are made to ensure clean cuts with diamond burs. This is important when carrying out surgical operations where accuracy is very important.
  • Heat Resistance: They are suitable for tasks in which there is generation of heat due to friction. An example is cavity preparation during tooth drilling. Carborundum burs do not lose their hardness even under high temperatures.

How to install

These are very essential instruments in dental practice. Their installation follows these simple steps:

  • Choosing the Right Bur: Select the appropriate carborundum bur based on the required dental procedure. Burs come in several shapes and sizes for specific tasks.
  • Preparing the Handpiece: Make sure to use a low-speed or high-speed handpiece, depending on the bur type. Handpieces should be cleaned and sterilized before use.
  • Inserting the Bur: Loosen the chuck of the handpiece by rotating the rear part (the nose cone) until the grip is freed. Then, insert the carborundum bur into the chuck. Position the bur so that it is parallel to the handpiece shaft.
  • Securing the Bur: Tighten the chuck by rotating the rear part in a clockwise direction. This will firmly secure the bur in place.
  • Testing the Setup: Before commencing any operation, it is advisable to run the handpiece at a low speed. This helps check if the bur is well locked and eliminates any vibrations.

How to use

Proper usage ensures effective performance and patient safety. The following are the guidelines for the utilization of carborundum burs:

  • Application Preparation: Prior to applying carborundum burs to any dental procedure, a brief medical history of the patient should be taken. This ensures that no patients have contraindications for treatments that involve dental tools. Infections may arise if there are open wounds.
  • Anesthesia Administration: If the procedure involves preparing cavities or other invasive procedures, local anesthesia should be injected where there is a need. This reduces pain, which is good for patients during treatment.
  • Handpiece Operation: Once anesthesia takes effect, the dental handpiece with the carborundum bur attached should be placed gently against the tooth surface. This should be done with a steady hand to avoid accidents. Switch on the handpiece so that the bur starts rotating and making contact with the targeted area.
  • Cavity Preparation: In cavity preparation, the round and fissure burs should be used to remove decayed tooth matter and shape the cavity walls. The dentist should always monitor the patient's response and pause when discomfort is noticed.
  • Finishing: When the required depth and shape are achieved, stop the handpiece and gently remove the bur from contact with the tooth. Hold the site with gauze to further stop bleeding while allowing the patient to rest before moving to the next stage.
  • Post-Procedure Care: After performing the procedure, all used tools, including the carborundum burs, should be carefully collected. They should be thoroughly cleaned and sterilized before the next use. Dispose of any single-use burs following health regulations.

Maintenance and Repair

The longevity of dental carborundum bur sets can be achieved through the following ways:

  • Proper Cleaning: After each use, manually cleaning burs is vital to eliminate debris and contaminants. Use a soft brush with mild soap and water. For further sterilization, autoclaving is preferable.
  • Inspection: Thoroughly inspect burs for wear, such as chipping or bending. Frequent checks mean higher performance and less risk of accidents during procedures.
