Structure and Properties of 3D Printed Zirconia Applied in Dentistry

During the last years, interest in application of additive manufacturing (AM), also known as 3D printing, becomes extremely popular various fields medicine including dentistry. Currently, metal and ceramic materials are most often used for dental prosthetics manufactured by printing. The yttria-stabilized zirconia (YSZ) ceramics has become best alternative metal-based restorations. In this regard, main goal review deals with studying effect printing parameters on macro- microstructure and, accordingly, mechanical properties sintered YSZ, basis, to give practical recommendations clinical dentistry further prospects. As researched recent methods such Laser-Stereolithography (Laser-SL) Stereolithography-Digital Light Processing (SL-DLP) based vat-photopolymerization technology discussed here. physical foundations technological these AM technologies considered. attention focuses effects thermal conditions during solidification (density, grain size, crystalline phase composition), which is controlled technologies. addition, true hardness biaxial flexural strength printed YSZ samples discussed. At last, advantages mentioned.
