Bredent Burs and Discs

Diatit Tungsten Carbide Burs

Diatit tools feature the advanced Diatit wear protection coating. This is a special material which is added into the surface of the bur after it has been produced. It hardens the tool surface and reduces the surface friction.

This comprehensive hardening process results in a tool which features very smooth rotation and precise cutting performance from the very beginning - and this is provided over a considerably long period. Accurate removal of material is ensured. Additionally, the service life of the tool (compared to uncoated carbide burs) is increased considerably by the hardening process.

A small dimple is prepared with the Diatit Center Drill (#330 006 60) to determine the position of the drill hole. The dimple will center the drill and keep it in position.

The hole is drilled with the 1.5mm Diatit Multidrill (#330 007 30). The dimple is used to guide the drill into position.

The waxing pins are inserted into the holes to check for proper positioning.

INSTRUCTIONS FOR USE DIATIT TUNGSTEN CARBIDE CUTTERS

Before using this product, please read and follow these instructions carefully.

1. Description of the Product
Cutters made of fine grain Tungsten carbides sintered onto a Tungsten carbide/cobalt base. Thanks for a special type of heat treatment (hot isostatic pressing), the sintered Tungsten carbide alloy is condensed again to reduce the remaining porosity immensely.
Diatit cutters are provided with a special anti-wear layer that, although it only adds 1 micron to the surface, penetrates up to 100 microns into the metal surface.

2. Advantages
Thanks to the Diatit anti-wear layer, these cutters exhibit an extremely high Vickers hardness value of 3700. Without this Diatit layer, they have a Vickers hardness of 1850.
This leads to:
" Exceptionally high structural strength and resulting sharp cutting edges over a long period of time, which will not disintegrate.
" Hardness values double those of cutters without an anti-wear layer.
" Three times the service life of cutters without an anti-wear layer.
" Grinding performance remains constant throughout a long period of time, which reduces costs and increases profit.
" The particles created during grinding cannot become attached to the finely honed; smooth coated cutting edges of the cutter
Whereas when using non-coated cutters, the particles may even become welded to the teeth of the cutter due to the heat and pressure involved.
If there are no particles on the cutting edges:
" The friction is reduced by half and less heat is generated.
" If the exterior shape of the cutting edge does not change, it cuts neatly and produces smoother surfaces.
" The cutter runs smoothly on the restoration.
" Less friction, reduced stress on the teeth of the cutter, which will not disintegrate.

Giflex-TR Diamond Disc

Giflex-TR is a disc for handpieces that features diamond-coating on both sides and is especially suitable for cutting dies out of plaster, refractory and resin. Calculated chip spaces in the area of the diamond coating ensure quick removal of the grinding dust and increase the cutting performance of the disc. Giflex-TR allows for quick, smooth, and reliable cutting even of very hard plaster and resin. Troublesome chattering and jamming of the disc is avoided.

Larger holes in the diamond free section reduce the friction heat. The disc will not overheat even if deep cuts are carried out. The running transparency allows for a better view into the saw cut.

Transflex Diamond Discs

Diagonally arranged cutouts for running transparency with high breaking strength and optimal grinding capacity.

Transflex is well suited for dividing and separating in the areas of the anterior and posterior teeth and in the approximate shaping. The specially diagonally arranged cutouts ensure running transparency with high stability and abrasiveness of the grinding disc.

Milling Bur System

Overview

The Bredent Three Step Milling system consists of 3 burs of the identical shape, but each designed for different surface finishing. This will allow you to drastically cut finishing time by giving you the capability to precisely pre-mill in the wax stage. After casting, the metal milling bur is used to do the final finishing. This metal bur is exactly the same shape as the wax bur which minimizes the milling time required on the metal. The final high shine polish is achieved with the polishing bur. Using this system, you can save costs, time and material.

Groove Burs

The groove bur exclusively serves to prepare grooves. For this purpose the groove bur is only moved up and down in the vertical axis. The cut on the face simplifies extending the grooves to the cervical direction. At speeds of 15,000 - 20,000 rpm a fine cutting performance and a mirror-like high luster on the milling surface are obtained.

Shoulder Burs

The occlusal shoulder is prepared with a special shoulder bur. The shoulder bur features a face cut which smoothens the bottom of the shoulder. Optimum use of this tool is ensured at speeds of 15,000 - 20,000 rpm. A mirror-like luster on the milling surface is achieved with the relief cut. Additional polishing is not required.

Non-Precious and Titanium

A rich quantity of milling and drilling oil is applied onto the milling surface and a speed of 20,000 - 25,000 rotations per minute is used for milling. While adding a copious amount of milling and drilling oil, the milling surface is prepolished with the polishing bur at 20,000 rotations per minute and then polished to high luster at 10,000 rotations per minute.

The cutting edge geometry has been especially designed for rapid removal of material. The relief ensures smooth running and allows very smooth surfaces on the object to be milled. The wide relief extends the edge life and avoids breaking of the sharp cutting edges.

It is recommended to wax the entire crown in wax prior to starting the milling work.

In the first step a shoulder with a margin step is prepared with a round 2.3mm parallel wax bur.

The insertion grooves are then prepared with the flat 1.0mm groove bur.

The final wax step is to mill an occlusal shoulder with the 2.7mm shoulder bur.

After casting the crown, the parallel surface is finished with the 2.3mm round metal bur.

The insertion groove is finished with the same groove bur. The bur should only be moved up & down in the vertical axis.

The occlusal shoulder is reworked with the 2.7mm shoulder bur.

Finally, a high luster is achieved on the parallel surface using the 2.3mm round polishing bur.

The bredent milling burs produce such a high shine that additional polishing is not needed..

A secondary element with anatomy is created with the Pi-Ku-Plast pattern resin. (Pg. 115 and 116)

The secondary element is cast and fitted onto the crown.

The low shrinkage of the Pi-Ku-Plast pattern ensures excellent precision of fit of the two pieces.
