The following instructions provide best results in preparations through careful handling of the diamond instruments and their application. Consideration of the teeth as well as perfect hygenic conditions are the main concern.
| • | Instruments must be sterilized before first and any further usage in an autoclave sterilizer with a sterilization pressure of 1-2 bar, a min./max. temperature of 120°C/150°C and a min. sterilization time of 25 minutes. |
| • | Instruments are to be selected by the head diameter to prevent from damaging neighbour teeth or tissue. |
| • | Rounded shapes should be favoured. |
| • | Instruments with coarse grit are not always indicated; usually they require a finish grinding operation. |
| • | Trays or original packing should be used for storing. |
| • | The shafts have to be secured properly and checked for minimum runout before use. |
| • | The burs should be set to the working speed according to the graphical diagram. It should be set before applying the bur to the object. |
| • | Spray cooling with a minimum flow of 50 ml/min must be provided. Additional cooling is required as burs longer than 21 mm or heads bigger than 2 mm are being used. |
| • | Forces should not exceed 2 N (appr. 200 p). Higher forces do not result in a quicker material removal, but increase the thermal load on the tooth. |
| • | Worn or damaged burs must be replaced immediately. |
| • | Burs should be cleaned in a "cleaning solution" first after use. See manufacturer’s instructions for details. |
| • | Burs can be brushed to remove material sticking to the diamond layer. |
| • | Dental diamond instruments are made of stainless materials. However, they must not get in contact with acids. |
| • | Our dental diamon tools are manufactured from high-quality components providing a long life time. However we recommend not to use the instruments after an expiration time of 10 years. |
Our tools with sintered bond are particularly suitable for processing ceramic materials and metal bondings. The high degree dimensional stability and the long service life are ensured by a special production technique.
(Lab tools with sintered bond))Tools with diamond grit in a sintered bond offer a variety of applications combined with a long tool life. Some simple rules ensure maximum use of their advantages.
| • | The tools should be set to the working speed according to the graphical diagram. |
| • | A slightly oscillating motion provides low cutting forces by a short length of contact. |
| • | Forces should be kept low to avoid heating and excessive tool wear. |
| • | Cutting discs with sintered bond can break easily due to the brittle structure of the material and should not be bent. |
| • | A soft cleaning stone is recommended for the cleaning of tools with sintered bond. This procedure will remove the top layer of the bond and release unused diamond grit. |
- with penetrated rimIn addition to proven cutting discs with surface layer for all grinding and cutting operations, we are the only manufacturer of cutting discs with penetrated rim covering the diameter range from 10 to 200 mm. This layer is - similar to a sintered bond - completely penetrated with diamond crystals. The discs allow thinnest cuts and extremely long service. They are constantly flexible and appropriate for technicians during cutting and lateral grinding of ceramics, porcelain, plaster and metals.
Surface layerPenetrated rim
(Lab tools with electroplated bond, dispersed, Fig. 354).
Cutting discs with electroplated bond and penetrated rim provide unique properties. Other than discs with a single layer, this type achieves a very long life time by a specific multilayer design. Though they are thin and flexible, much more than the ones with sintered bond. They surpass all other types of discs when handled properly.
| • | The tools should be set to the working speed according to the graphical diagram. |
| • | Cutting discs with penetrated rim are designed for separating. An oscillating motion should be applied while moving in radial direction. |
| • | Although these discs are flexible, lateral grinding should be performed at very low forces only. High lateral forces may result in breakage, as the thickness of the blade usually is only 0,12 mm. |
| • | Bending or turning when cutting into a slot must be avoided. |
| • | A soft cleaning stone is recommended for the cleaning of tools with sintered bond. This procedure will remove the top layer of the bond and release unused diamond grit. |
- synthetic diamondWe manufacture our FG tools in varying grit sizes between 504 and 554 (acc. to ISO standards), with choice of one of two types of grit: natural and/or synthetic (”S“) diamond (limited to ISO 524 and certain types). The natural diamond crystals typically have an irregular shape and sharp cutting edges which ensure a quick material removal. Layers containing the block-type, synthetic diamond crystals provide a professional preparation with less surface roughness. Those FG diamonds have a black coating to increase the optical contrast between tool and tooth.
