Prima Taper Flat End Diamond Bur 845

Description

What Is the Prima Taper Flat End Diamond Bur?

The Prima Taper Flat End Diamond Bur 845 has a tapered working head with sloping sides and a flat end. The head diameter decreases towards the free end of the instrument.

Its diamond-coated surface removes and shapes hard tooth tissue through abrasion as the bur rotates. The tapered sides and flat end allow different parts of the working head to be used according to the intended preparation.

Model 845 belongs to Prima’s Taper Flat Endrange. This code identifies the instrument’s shape and model. Head diameter, working head length and grit grade must also be checked to identify the product fully.

Applications of the Taper Flat End Diamond Bur

This geometry can be useful for preparations requiring inclined walls and flat areas. Instrument selection should reflect the treatment plan, intended preparation shape and amount of material removal required.

Shaping Inclined Walls

The tapered head can be used to create or refine wall inclination. The final angle depends on more than the bur shape; alignment of the instrument’s axis and the direction of movement also influence the result.

Removing and Refining Hard Tooth Surfaces

The lateral diamond-coated surfaces allow localised removal of hard tissue and refinement of surface contours. Head diameter and length should suit the dimensions of the working area to help limit contact to the intended region.

Preparing Areas Requiring Flat-End Geometry

The flat end can be used to prepare areas where this geometry is appropriate. Its positioning and contact must be controlled to maintain the intended shape and avoid unwanted removal.

Choosing the Right Prima 845 Bur

Selecting the Head Diameter

Model 845 is available in several nominal head diameters. The selected diameter should suit the working space, intended surface and amount of reduction required.

For example, in 845/014, the designation 014 indicates a nominal head diameter of **1.4 mm**. It does not identify the head length or grit grade and must be considered alongside the other product information.

Selecting the Working Head Length

Head length is not the same across all sizes of model 845. Shorter and longer heads provide different lengths of abrasive contact with the tooth.

Working head length differs from overall bur length. Head length describes the abrasive section, while overall length includes both the head and shank. Selection should take account of access requirements and instrument control.

Checking the Grit Grade

On the official product page, sizes of model **845 without the KR suffix** are listed with **Medium grit. Grit options associated with other models in the Taper Flat End range should not be assumed to apply to model 845.

Medium grit provides moderate abrasive action. Material removal and the resulting surface finish also depend on operating speed, applied pressure, cooling and technique.

Prima Taper Flat End Diamond Bur 845 Specifications

The listed sizes reflect the options presented for this model and do not indicate that every option is available in stock. 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, confirm compatibility with the handpiece and inspect the bur for visible damage. The instrument must be fully inserted and securely retained.

Operating speed, cooling and applied pressure must follow the manufacturer’s instructions and the requirements of the procedure. The tapered head geometry must also be considered when positioning and moving the instrument.

Care and Maintenance

Inspect the bur for wear or damage before use. Worn or damaged instruments can impair abrasive performance.

Cleaning and preparation for reuse must follow the instructions for the specific product. Sterilization methods and reusability should not be determined solely by the bur’s material or appearance.
