Quick and efficient – removal of amalgam fillings
What are the most important points when removing amalgam fillings? Old fillings should be removed in the shortest possible time – yet with the minimum generation of heat.

These two all-important requirements exclude the use of many instruments right from the start, for example diamond abrasives – especially used ones. Usually developed for other purposes, such as the preparation of cavities, diamond abrasives do not have sufficiently sized chip removal spaces. This results in a tendency to undesirable clogging, i.e. the instrument gets completely clogged-up with dental debris and loses its cutting efficiency. The adverse consequences, such as a prolonged treatment and excessive generation of heat, could be avoided with the right choice of instrument.

In this context, special Tungsten carbide burs have proved particularly useful – for example the amalgam remover H32 which was especially developed to suit this purpose. The H32 is used by drilling into the filling in axial direction or from an inclined position. Several longitudinal and transversal separation grooves are cut.

In order to avoid excessive friction heat and to allow a speedy treatment, please observe the following recommendations when removing amalgam:

• Work with sufficient spray cooling at all times (at least 50ml/min).

• When given the choice, it is preferable to use the amalgam remover H32 in the red contra-angle rather than the turbine.

• Only ever apply low contact pressure.

• Insert the H32 in axial direction or from an inclined position. Then cut several longitudinal or vertical separation grooves, the size of which depends on the dimension of the filling. Finally remove all remaining filling residues.
