Resumen

PENDOLA, Martin  y  CARTER, John. Crystal Modification on Lithium Disilicate Glass Ceramics Sintered Using Microwaves. Int. J. Odontostomat. [online]. 2017, vol.11, n.4, pp.461-466. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2017000400461.

Microwaves are an interesting alternative to process dental ceramics. It is well documented that Microwave Hybrid Sintering (MHS) allows important savings in time and energy consumption. However, little is known about its effect on lithium disilicate glass ceramics, a popular material in dentistry today. We analyzed the microstructure of lithium disilicate glass ceramics sintered with MHS compared with conventional sintering. We sintered lithium disilicate glass ceramics using MHS and conventional furnaces, and we analyzed the samples using X-Ray diffraction and SEM. Samples sintered with MHS showed an increased crystalline phase, with an increased number of crystals. These crystals have larger perimeters compared with samples sintered in conventional furnaces. MHS produced a different crystallization pattern and crystal/ matrix ration in lithium disilicate glass ceramics when compared to conventional sintering. This can be associated with the improved mechanical properties of these materials reported previously.

Palabras clave : microwave sintering; glass ceramics; crystalline phase; dental ceramics.
