However, its esthetics are compromised by its poor translucency and grayish-white appearance. Zirconia exhibits a tetragonal-to-monoclinic phase transformation on cooling, which is accompanied by a 3% to 5% volume increase. Clinical Implications While fully stabilized zirconia (cubic) has been developed for use
