“…Though this will probably increase the chipping risk of the veneering porcelain, the use of monolithic TZP will solve the chipping problem, and the use of monolithic translucent TZP will also improve the appearance. In addition, smooth-polished TZP has been reported to cause less wear on the antagonist enamel, making it more clinically useful 24,34) . Furthermore, the fact that the flexural strength of all the monolithic TZP showed approximately 1,000 MPa indicate no requires for drastic increase in thickness compared with conventional crown restorations, and it may become a clinical benchmark for decreasing the amount of tooth to be removed.…”

This study aims to investigate the effectiveness of monolithic translucent TZP with different colors and porcelain-layered TZP by evaluating their colors and strengths. Different mixing ratios of Zpex to Zpex-Yellow as translucent TZP, conventional opaque TZP (TZ-3YB-E) (Tosoh, Tokyo) as a control, and veneering porcelain (CERABIEN ZR, body porcelain, Noritake, Tokyo) with shade A3 as a typical shade. Disk-shaped specimens of 13 mm diameter and 1.5 mm thickness were prepared. These specimens were observed under reflected and transmitted light, and the translucency parameter (TP) values were measured. Strength was also evaluated with flexural strength in a biaxial bending test. The TP values of the monolithic TZP, Zpex100>Zpex70>Zpex50>TZ3YB, were larger in this order. The flexural strength of all the monolithic TZP showed approximately 1,000 MPa. It is suggested that colored translucent TZP is clinically useful when used as monolithic restorations.

“…Preis et al [37] investigated the surface properties (roughness, composition and phase transformation) of monolithic zirconia after dental adjustment procedures (grinding and polishing) and wear simulation. The findings of the study revealed that grinding significantly increased the roughness of sintered zirconia, whereas, polishing significantly reduced R a .…”

Zirconia restorations have been used successfully for years in dentistry owing to their biocompatibility and good mechanical properties. Because of their lack of translucency, zirconia cores are generally veneered with porcelain, which makes restorations weaker due to failure of the adhesion between the two materials. In recent years, all-ceramic zirconia restorations have been introduced in the dental sector with the intent to solve this problem. Besides the elimination of chipping, the reduced occlusal space requirement seems to be a clear advantage of monolithic zirconia restorations. However, scientific evidence is needed to recommend this relatively new application for clinical use. This mini-review discusses the current scientific literature on monolithic zirconia restorations. The results of in vitro studies suggested that monolithic zirconia may be the best choice for posterior fixed partial dentures in the presence of high occlusal loads and minimal occlusal restoration space. The results should be supported with much more in vitro and particularly in vivo studies to obtain a final conclusion.

“…Intraoral adjustment thereby increased the zirconia surface roughness and, by implication, the wear damage. As a conclusion, a perfect polish has been claimed mandatory for a suitable wear resistance of zirconia and the opposing antagonists [5].…”
