Open the catalog to page 1Conception Dentsply Maillefer’s tungsten carbide burs are cut from high tenacity, micro grain hard metal. After the cutting edges of the active part have been ground by a precision tool impregnated with fine grained diamond, each bur individually undergoes a strength test. Each bur is also visually examined prior to packing to guarantee perfection. These inspections are in addition to 6 examinations, which take place during production. The cutting geometry, which is specific to each form and each use (cavity burs, metal burs, surgical or finishing burs, ...) provides both a very significant...

Open the catalog to page 4TUNGSTEN CARBIDE CAVITY BURS Applications : Excavating carious dentine. Recommended speed (RA) : 500 to 2’000 rpm. Characteristics and advantages : Specially developed tooth geometry (pronounced cutting angle) Efficient cutting and good material evacuation Sensitive touch transmission when in contact with healthy dentine Tactile distinction between healthy and carious dentine Reduced neck Good visibility Green identification ring Stainless steel shank Tungsten carbide head and neck
Open the catalog to page 5TUNGSTEN CARBIDE METAL BURS Characteristics : Due to their tooth pattern geometry, these burs are specially recommended for the removal of amalgam and composite fillings. Applications : Due to their form, they permit : The removal of the old amalgam filling and preparation of the cavity to receive the new filling The reworking of the occlusal face of the inlay core E 0570 Characteristics : The shape of this bur is recommended for cutting metal and for forming stumps. Compared to diamond cutters, this bur : – wears much less rapidly (no breaking away of diamond grains) – leaves a smooth...
Open the catalog to page 6TUNGSTEN CARBIDE METAL BURS Transmetal Cylinder Applications : Specially recommended for cutting crowns and bridges (gold, nickel-chromium and other non-precious alloys). The active axial part is applied to the surface to be cut with moderate pressure. An alternating up and down movement improves the efficiency of the bur. Recommended speed : between 120’000 and 180’000 rpm. Characteristics : Spiral drill with extra-fine cross cut guaranteeing effective debris removal (no accumulation), hence preventing heating. Transmetal Pear Applications : The pear Transmetal is recommended for...
Open the catalog to page 7TUNGSTEN CARBIDE AND DIAMOND ENDO BURS Long Neck Characteristics : Long neck for enhanced visibility. Applications : Excavating carious dentine Widening and finishing cavity access Location of the root orifices Characteristics : Diamond plated conical bur with round tip (grit size 130 µm). Applications : Opening and preparing the pulp cavity. Cavity access performed within one operation using a single bur on monoradicular teeth and shaping, on pluriradicular teeth, of a conical access adapted to the insertion of the Endo-Z and Diamendo burs Characteristics : Diamond plated conical bur with...
Open the catalog to page 8TUNGSTEN CARBIDE ENDO BURS Applications : The ideal bur to produce a funnel-shaped opening of the pulp cavity to give access to the root orifices. Recommended speed : 160’000 to 300’000 rpm. Characteristics and advantages : Non-cutting extremity Enlargement of the access cavity with preservation of the original pulp floor anatomy (no risk of perforation – easy location of the canal orifices) Conical shape Quick elimination of all interferences to give direct access to the instruments in the root canal Helical tooth pattern (6 blades) Adapted to all teeth anatomies Gold plated shank Easy...
Open the catalog to page 9TUNGSTEN CARBIDE SURGICAL BURS Characteristics : Active laterally and at the end Small dimensions Smooth shaft Applications : First phase of sectioning an impacted wisdom tooth prior to using the Zekrya bur (E 0151) ; as the smooth shaft of the bur is opposite the folded-back flap, there is no risk of it becoming damaged. Removal of crowns or old amalgam fillings. Characteristics : Extended neck; tapered active part, oval and cutting at the tip Wide field of vision assists guidance; simple insertion along small impacted parts Applications : Resection and removal of fine broken roots. Bone...
Open the catalog to page 10TUNGSTEN CARBIDE SURGICAL BURS Applications : Sectioning an impacted wisdom tooth prior to its extraction Separating roots Removing a broken root stump Cutting a tooth horizontally at neck level Reworking temporary teeth of acrylic material Preparing a shoulder on the vestibular side of the tooth Caractéristiques : Active laterally (no vibrations on account of its 6 helical cutting edges) Active at end by means of its hemispherical, cutting tip 6 helical cutting edges: active laterally
Open the catalog to page 11TUNGSTEN CARBIDE FINISHING BURS Finishing work on amalgam and composite fillings Axial tooth pattern-Cone Characteristics : These burs with a fine cut and axial tooth pattern have the following advantages over diamond cutters : Higher efficiency Production of a clean and polished surface Their non-cutting tips enable the practitioner to work under the gum E 0510 > 8 blades to remove the composite surplus. E 0536 > 16 blades for the finishing. E 0537 > 30 blades to polish. Applications : Finishing work on composite fillings. Cone round Characteristics : Identical to those described above....
