Plaster:

The tried and tested backbone of work at the dental laboratory.

Models are the backbone of all dental work and plaster is currently still the most commonly used model material. Whether a situation model, master model or saw model, working with plaster is an art in itself because this is where the foundation for precision is laid.

Plaster:

The tried and tested backbone of work at the dental laboratory.

Models are the backbone of all dental work and plaster is currently still the most commonly used model material. Whether a situation model, master model or saw model, working with plaster is an art in itself because this is where the foundation for precision is laid.

Whether rough finishing or fine grinding depends on the specific task. Exposing the preparation margin, for example – a true challenge – requires high-precision tools. An egg-shaped or pear-shaped carbide bur, e.g. the H71EF or the H77EF in size 023, is ideal. The shape and toothing of these instruments are perfectly suited for this indication. Both tools have EF teeth. Their excellent cutting performance ensures a clean, smooth surface and precise finish.

Making saw cuts is a particularly difficult task that requires a steady hand and the right tool. Komet offers various diamond discs for work on plaster. For example, the double-sided diamond disc 8964 enables efficient cutting of the dental arch. The disc glides through the plaster without “fluttering” and leaves a clean, straight cut.

Different types of cutters are available for grinding the dental arch or model or for carefully finishing the functional margin.

Carbide cutters with SGFA and GEA toothing are ideal for work on wet and dry plaster. The reduced number of blades means that material can be removed without any problems. Thanks to the large chip space, the cutter does not clog up with moist plaster.

The toothing with left-hand twist ensures safety and protection during use. It ensures that the tool does not get pulled out of the chuck during intensive use but is pressed in instead. The beveled blades create an optimum surface quality.

The types of toothing:

  • SGFA (bulk material removal, for use on wet plaster)
  • GEA (bulk material removal, for use on dry plaster)
  • E (average material removal, for use on dry plaster)

More safety. More substance removal. No clogging.

The SGFA cutters are an advanced version of the proven cutters with super-coarse SGEA toothing and guarantee effective and, above all, safe work on all dental plasters. The reduced number of cutting edges enables trouble-free material removal during the entire cutting process. Thanks to the largest possible chip space, moist plaster can no longer clog up the bur.
