Description
What Is the Prima Barrel Diamond Bur?
A barrel bur is a type of dental diamond bur named after the shape of its working head. Its broad, barrel-like geometry can provide a larger contact area than a small round bur.
The Prima Barrel Diamond Bur is identified by the code 811. Diamond particles on the head remove hard tissue through abrasion as the instrument rotates. The amount of material removed and the resulting surface finish depend on the bur dimensions, grit grade, applied pressure and operating technique.
Applications of the Barrel Diamond Bur
The barrel geometry can be useful during selected stages of hard tooth tissue removal and contouring. Selection should reflect the treatment plan, working area and amount of reduction required.
Removal of Hard Tooth Tissue
The relatively broad abrasive surface allows contact with a larger area. This feature may be considered where reduction across broader surfaces is required.
Head diameter and grit grade must suit the available working space. A larger head or coarser grit is not automatically more appropriate for every treatment stage.
Shaping and Refining Tooth Surfaces
The barrel-shaped head can be used to shape and refine selected tooth surfaces during preparation. Instrument orientation and movement influence the contours produced.
Selection and use should take account of the intended geometry, preservation of tooth structure and requirements of the procedure.
Choosing the Right Prima Barrel Diamond Bur
When selecting the Prima Barrel Diamond Bur 811, head diameter, working head length and grit grade should be considered together.
Selecting the Head Diameter
The product is listed in three nominal head diameters:
– 811/032: 3.2 mm head diameter
– 811/035: 3.5 mm head diameter
– 811/0494.9 mm head diameter
Head diameter influences the potential contact area and access to the working site. The selected size should suit the available space and intended surface. The size designation alone does not identify the grit grade or all product specifications.
Selecting the Head Length
The working head length varies between sizes. The 811/032 has a 5 mm head length, while the 811/035 and 811/049 have 7 mm head lengths.
Head length differs from overall bur length. It describes the abrasive working section and should be selected according to the treatment surface and access requirements.
Selecting the Grit Grade
Diamond particle size influences abrasive action and the resulting surface finish. The grit grades listed for this range include:
– Medium: for moderate abrasive action.
– Coarse: for greater material removal where appropriate.
-Extra Coarse: for greater material removal using larger abrasive particles, where appropriate to the procedure.
Not all grit grades are offered in all three sizes. Size and grit must therefore be selected together.
Prima Barrel Diamond Bur 811 Specifications
The range of sizes and grit grades reflects the variety within this product series and does not mean that every combination is available. The specifications of the selected version should be checked against its packaging and product information.
Handpiece Compatibility and Operating Considerations
Before use, check the shank type and confirm compatibility with the handpiece. Full insertion and secure retention are essential parts of instrument preparation.
Operating speed, cooling and applied pressure must follow the manufacturer’s instructions and the requirements of the procedure. Head size and grit grade must also be considered when selecting operating conditions.
Care and Maintenance
Inspect the bur for wear or visible damage before use. Worn or damaged instruments can impair abrasive performance.
Cleaning and preparation for reuse must follow the instructions for the specific product. Reusability and sterilization methods should not be determined solely by the bur’s appearance or material.
