“…Experimental glass-ceramics in the system Li 2 O-Al 2 O 3 -CaO-SiO 2 are currently the object of extensive research work. The choice of adequate additives is critical in the development of tougher and higher-strength glassceramics (Anusavice et al 1994b). Differential thermal analysis can be efficiently used to determine the heat treatment leading to the maximum lithium disilicate crystal population in the shortest amount of time, thereby optimizing the nucleation and crystallization heat treatment of this type of glass-ceramic (Parsell and Anusavice, 1994).…”

For the last ten years, the application of high-technology processes to dental ceramics allowed for the development of new materials such as heat-pressed, injection-molded, and slip-cast ceramics and glass-ceramics. The purpose of the present paper is to review advances in new materials and processes available for making all-ceramic dental restorations. Concepts on the structure and strengthening mechanisms of dental ceramics are provided. Major developments in materials for all-ceramic restorations are addressed. These advances include improved processing techniques and greater mechanical properties. An overview of the processing techniques available for all-ceramic materials is given, including sintering, casting, machining, slip-casting, and heat-pressing. The most recent ceramic materials are reviewed with respect to their principal crystalline phases, including leucite, alumina, forsterite, zirconia, mica, hydroxyapatite, lithium disilicate, sanidine, and spinel. Finally, a summary of flexural strength data available for all-ceramic materials is included.

“…The mechanism of films adhesion at the first stage has been explained by several authors by the formation of oxides and hydroxides of the metal [26,27], in our system; the mentioned species may exist, nevertheless, the adhesion of the films does not occur. According to the references [28][29][30][31], silver ions tend to exchange with glass ions and it is possible that silver diffuses through the glass substrate by means of this reaction, modifying the glass surface. This phenomenon can explain the pores observed at the substrate-film interface (Figs.…”
