Guido Testa, Dental Technician - "More efficiency with the large wax knife"

Guido Testa, Dental Technician, Italy:
"When waxing up partial and full dentures I work with a large wax knife, which is perfectly designed to solve two important tasks: Transfer of large amounts of wax and delicate and anatomical contouring. The curved and slender tip ensures optimum contouring of the palatal wax-up and interdental spaces."

Terry McQuiston - Blasting technology

Burnout and pressing of the invested restorations is now performedand once the rings have cooled the most tedious part of the process begins... devesting.

I come across so many labs with less than adequate sand-blasting equipment. This can be one of the biggest drains of time... and therefore profit. In the realm of affordable, proficient, and reliable sand blasters, I always recommend the Basic quattro IS. It is everything necessary for any glass beading or sandblasting job the lab will run across.

In addition, the IS (instant shut-off of abrasive flow) feature will save the lab hundreds of dollars a year at a minimum.

Dr. Bonnet - Basic master + Silent TS

With regards to us, we chose the fine sandblaster Basic master together with the extraction unit Silent from Renfert.

When we speak of useful devices in the practice, the fine sandblaster is always at the top of the list.

This unit supports us daily in a variety of different areas and is very quick and easy to operate.

Luke S. Kahng, CDT - Vario jet

The Vario jet sandblaster is fully automatic but can also be used in a manual mode. The design allows for fine results and gives the technician the freedom to prioritize his time. Use it with metal casting and pressed ceramic material and never worry about maintaining pressure control. Since more than one restoration can be sandblasted at a time, the technician can be productive elsewhere.
I am appreciative of the time saving effectiveness of this product.

Previous experiences
I will not be the only one to have experienced the following: extractors that are so inaccessible nobody wants to change the bag, not to mention the even more complicated filter. I know extractors that have started when a unit has been switched on, though it was not connected to the extraction and in turn extractors whose automatic system has simply not reacted. I also know all too well the inconvenience of repair cases when the extractor had to be away from the lab for a long time.
Operating for 6 years
My experience with the Silent (Editor’s note: the previous model to the Silent TS mentioned above) has been completely different, as it has been in continuous operation in my lab for 6 (!) years without any repairs or problems. The only thing that I have to do now and again is change the dust bag and eventually the filter, which I change very conveniently at the front of the unit, without having to rebuild half of the workstation, as was previously the case. Apart from that, I only installed the unit when it was delivered. That is what I call low maintenance. Calibration is very easy and it can be finely adjusted, so that my handpiece starts the extractor exactly at the correct motor speed. I like working with this unit, particularly in combination with the Dustex master plus and I use it for all applications.
Perfect combination: Silent & Dustex
When I worked without a dust box, I thought that the really strong extraction was completely adequate for protecting my health. One day, however, I noticed an excessively thick layer of dust on a slightly concealed area, i.e. on lamps hanging from the ceiling. This meant that with some types of work insufficient dust was being extracted using an extractor clamp (e.g. dental stone trimmed using a handpiece). The problem has been solved since I also started using the Dustex master plus. At the same time, it is also provides excellent protection against unpleasant odours when preparing old dentures.
If I should require a new extractor at sometime in the future, it must have exactly the same advantages as the Silent, because I don’t want to go back to the previous situation.

Robert Kreyer CDT - Wax technology

To create aesthetic and functional prosthetic dental art a technician must possess;
the knowledge of anatomy, aesthetics, and function within an individual oral environment.
the ability to visualize conscious thoughts into three dimensional reality according to variables involved, expectations and desires.
the proper tools, instruments and materials which become an extension of ones hands and thoughts enabling a technician to create aesthetic and functional removable prosthetics.

Renfert electric waxing equipment and instruments such as the Waxlectric II, Waxprofi, and Vario E are the proper technical tools which enable me to create personalized removable prosthetic dental art

Luke S. Kahng, CDT - GEO Natural

I love GEO Natural Wax by Renfert. The product is completely reliable for its excellent form and shape. Carving is very easy when using the product to create natural tooth morphology.
When the Waxlectric tip is applied to the model, there is no question that the application will be accurate.
Consequently, shaping the contours is made easier by the precision of the material and the instruments.When I cast and press the wax, the final outcome is predictable and correct. My time and material usage are conservatively saved when I use this product.
The efficiency of GEO Natural Wax and the Waxlectric unit by Renfert can’t be overestimated.
