Description

Prima Dental Carbide Burs: British Dental Instruments

Choosing the right dental bur influences preparation accuracy, material removal and surface finish. This page introduces the main types of dental burs, the British manufacturer Prima Dental, and the features and applications of its carbide bur range.

What Is a Dental Bur and What Is It Used For

A dental bur is a rotary instrument fitted to a turbine, contra-angle or straight handpiece, depending on its shank type. Dental burs are used to cut, prepare, shape and finish tooth structure and restorative materials. Dedicated models are also available for oral surgery.

Rotary polishing instruments, sometimes referred to as “polishing burs”, are used to reduce surface roughness and improve the gloss of teeth and restorations.

Types of Dental Burs and Rotary Instruments

Dental burs and rotary instruments can be classified by the material of their working part and their intended application. The main groups include:

– Carbide burs: These have tungsten carbide cutting heads. Depending on their design, they are used to prepare tooth structure, cut certain metals and restorative materials, or finish restorations.

– Diamond burs: These have diamond-coated working surfaces and use abrasive action to prepare tooth structure and adjust certain restorative materials.

– Steel burs: Usually made from hardened steel, suitable models are used to remove carious dentine and perform selected stages of cavity preparation.

– Finishing and polishing instruments: Finishing burs, including multi-bladed carbide models, refine contours and reduce irregularities. Abrasive polishers further smooth surfaces and improve gloss.

Finishing and polishing instruments are grouped by application, so this category overlaps with classifications based on material.

The range includes designs for different clinical tasks, with cutting head geometry and blade configuration varying according to the intended application.

Types of Prima Dental Carbide Burs

Prima Dental groups its carbide burs by application:

– Operative: For cavity preparation, cutting and shaping tooth structure.

– Orthodontic: Includes models for removing residual adhesive after bracket removal and selected interproximal applications.

– Trimming and finishing: For removing excess restorative material, refining contours and finishing restorations before final polishing.

– Surgical and oral surgery: Includes dedicated models for procedures such as bone cutting or tooth sectioning, subject to each model’s intended use.

– Metal cutting — Predator: Includes models for cutting metals and removing certain restorations and crowns. Suitability depends on the specific bur and the material being cut.

How to Choose the Right Carbide Bur

Prima carbide burs are available in various head shapes, diameters and lengths. Available sizes and shank types differ between models, so selection should be based on the specifications of the individual product.

The main selection criteria are:

– Head shape and diameter: These should suit the intended preparation, the dimensions of the treatment area and the amount of material to be removed.

– Head length and overall length: These should provide appropriate access to the working area.

– Number and arrangement of cutting blades: These influence cutting behaviour and surface finish. Plain-cut models have no cross-cut grooves, while cross-cut models have grooves across their cutting blades.

– Shank type: Friction-grip (FG) burs fit compatible turbines and contra-angles; right-angle (RA) burs fit latch-type contra-angles; handpiece (HP) burs fit compatible straight handpieces. Source: Example Prima Bur Dimensions and Shank Options

The final choice should take account of the material being treated, the product’s intended use and the manufacturer’s instructions for operating speed, applied pressure and cooling.
