Techniques of working


Preparation - model fabrication

Every procedure in dental technology is based on a dimensionally stable and accurately detailed model fabricated mainly from specially developed dental stones. These dental stones must conform to comply with the current EN ISO 6873 standards.

We are working together with the reputable gypsum manufacturer and specialist in this sector, Dr. Böhme & Schöps Dental GmbH, Goslar, Germany.

This of course brings offers you, the customer, obvious advantages to you, the customer. Now you can meet all your requirements for model materials and dental stones by choosing from SILADENT´s comprehensive range. A suitable stone is available for every dental application, regardless of whether high purity natural stones or special stones manufactured from synthetic components raw materials are required.
 

The SILADENT flaskless duplicating

Model with adhesive duplicating tape ready for duplicating In dental technology, duplicating models for chrome-cobalt has always involved using flasks in a variety of shapes and sizes. When using the patented SILADENT system, flasks are no longer required.

In the early 1980´s SILADENT introduced a new group of materials to dental technology by developing and formulating silicones which are suitable as an alternatives to agar agarbased duplicating gels for duplicating models used in dental technology. This new method of duplicating using silicone was the basis for further innovative developments - especially in materials and technical methods - and has led to the current well-known flaskless SILADENT technique.

For further information about the SILADENT flaskless duplicating technique refer to our Technical Brochure which may be obtained from our sales representative or direct from the SILADENT technical department.
 

SILADENT- investments

Essential components of the SILADENT technique are phosphate-bonded investments, specifically developed for casting all types of dental alloys, are essential components of the SILADENT technique. SILADENT investments, including Premium universal investment, cover all appli-cations, from fine-particle for use when casting CrCo partial frameworks (Granisit®, Micro) or fine to ultra-fine for crown and bridge cases (Silavest KB), including speed technique or for conventional burnout with different temperature hold-stages or for both.

At SILADENT we have been developing phosphate-bonded precision investments for over ten years. Top priority has always been given to the requirements of dental technicians in their often hectic, work day. The result of this develop-ment is an established technique that has been copied many times.

A generally faster pace of life has also had an effect on dental laboratories leading to a demand for investments which can be heated up quickly and which but still remain very precise. We have met these demands with the introduction of the Presto Vest and Premium investments which supplement our current range. Both investments may also be heated conventionally.

We have now also introduced JET 2000 for CrCo alloys, the first genuine speed-cast investment with virtually ideal properties.A patent is pending for the composition and manufacturing process of JET 2000.

In our ultra-modern mixing plants we manufacture our investments in mixing units for loading the blast furnacesbatches. Our manufacturing process is based on high-quality raw materials and a balanced composition, ensuring long-term consistent product quality.

Comprehensive production control and accurate documen-tation help us guarantee reliable results and consistently high precision of fit and surface quality. Not only the tech-nical specifications but also the technical application of every production load batch are precisely controlled. This offers us and our customers complete confidence when using our investments. We comand high standards from the all test results and manufacture only consistently high-quality product demanded by our customers’ requirements.

           


 

SILADENT- silicone Sleeves


All SILADENT investments may be used without metal rings. SILADENT-silicone sleeves with plastic base plates are an economical alternative to metal rings and rubber bases. Using this method, the wax pattern is affixed to the plastic base plate with a sprue in the usual way.

The silicone sleeve is placed over this and the wax pattern invested using the normal procedure. The base plate and silicone sleeve are removed prior to placing the ring in either a hot or cold furnace. With proper care, these accessories may be reused indefinitely.

  • Heat treatment of metal rings is no longer required
  • Ring liners are no longer required
  • Divesting is much easier
  • Considerable savings in time and material cost
  • Allows overall uniform expansion of the investment
  • The outer wall of the mould has a greater surface area due to the corrugated inner surface of the silicone sleeve
  • Heat is absorbed faster, shortening the preheating procedure and allowing casting to be carried out sooner.
