Microwave sintering of dental ceramics

T
he use of ceramics in dentistry, and across the
biomedical field, has been increasingly improving
and expanding in the last years. Improvements in quality,
versatility and mechanical properties have played a crucial
role in the expansion of the indications and purposes of
these materials in dentistry and many other fields. While
much research to improve ceramics has been focused in
the modification of the chemistry of the materials, the
processing methods has not been dramatically modified in
the last years. Sintering, a key process of the production
of dental ceramics, has remained relatively unmodified
over the years. Microwave sintering, a technology which is
common for industrial settings (communications, industrial
drying and heating), it is suitable for dental ceramics. The
advantages of a volumetric heating reduce dramatically the
processing times, and therefore, the energy consumption.
The technology is easily adaptable and available in most
of the markets, with a lot of possibilities for engineering a
new generation of devices. The use of microwave sintering
not only reduces the processing costs, as time and energy
savings, but also offers a very attractive “side-effect”: the
improvement of mechanical properties of the material,
leading to an extension of the service life, which has a
huge impact in the clinical performance for the patient.
In this presentation, we will show the main characteristics
of the process, and we will present the qualitative and
quantitative results of our sintering protocols designed for
dental ceramics processed using microwaves.
