Impact of high-speed sintering on translucency, phase content, grain sizes, and flexural strength of 3Y-TZP and 4Y-TZP zirconia materials.

Statement Of Problem: The lengthy sintering time of zirconia is costly and limits applications. The consequences of shortening the sintering time are mainly unknown.

Purpose: The purpose of this in vitro study was to test and compare 2 high-speed sintering protocols and 1 conventional sintering protocol on the translucency, phase content, grain sizes, and flexural strength of 3 zirconia materials.
