TECHNOLOGY

SST is an advanced manufacturing technique for creating protocols, implants, and medical-dental prostheses based on the construction of collapsible shells of zirconia silicate composites (ZrSiO4). The negative mould cavity is filled with particulate material and then sintered to create a range of components. Unlike traditional processes, which use binders, anti-caking agents or wet process control, SST makes use of the natural frequency of the powder to perform compaction and minimum spacing between one grain and another and perform a dry powder sintering, using biomaterials available on the market.

​

The shells generated by SST carry out air and moisture adsorption through controlled microporosities, subsequently creating isostatic pressure to ensure better densification and sintering of the processed materials. In this way, better surface quality and mechanical behaviour are obtained with the natural biocompatibility from available materials.
