“…Currently, subtractive manufacturing methods are considered the gold standard for fabricating zirconia dental restorations, but AM technologies are in continuous development. Limited dental literature has assessed the potential of AM zirconia for prosthodontic dental applications 6–17 . Among the different AM technologies available to process zirconia material, vat‐polymerized AM zirconia including stereolithography (SLA), digital light processing (DLP), and lithography‐based ceramic manufacturing (LCM) methods are frequently selected in the dental field 6–11,13,15–17 …”

Purpose To evaluate the chemical composition, flexural strength, and Weibull characteristics of milled and lithography‐based additively manufactured (AM) zirconia. Materials and methods A virtual design of a bar (25×4×2 mm) was completed using a software program. The standard tessellation language file was used to manufacture all the specimens: 3Y‐TZP zirconia (Priti multidisc ZrO2 monochrome) milled (M group) and 3Y‐TZP zirconia (LithaCon 3Y 210) lithography‐based AM (CeraFab System S65 Medical) (AM group) bar specimens (n = 20). The chemical composition of the specimens was determined by using energy dispersive X‐ray (EDAX) elemental analysis in a scanning electron microscope. Flexural strength was measured in all specimens using 3‐point bend test according to ISO/CD 6872.2 with a universal testing machine (Instron Model 8501). Two‐parameter Weibull distribution values were calculated. The Shapiro‐Wilk test revealed that the data were normally distributed (p < 0.05). Flexural strength values were analyzed using independent Student's t‐test (α = 0.05). Results There were no major chemical composition differences observed between M and AM groups. The AM specimens (1518.9 ± 253.9 MPa) exhibited a significantly higher flexural strength mean value compared to the milled (980.5 ± 130.3 MPa) specimens (DF = 13, T‐value = –5.97, p < 0.001). The Weibull distribution presented the highest shape for M specimens (11.49) compared to those of AM specimens (6.95). Conclusions There was no significant difference in the chemical composition of milled and AM zirconia material tested. AM zirconia tested exhibited significantly higher flexural strength compared with the milled zirconia evaluated.

“…Surface texturing of 3Y-TZP zirconia ceramics was found to have a large effect on wear against Si 3 N 4 ceramics and 304 stainless steels [719]. 3D printed zirconia, Ti6Al4V, and resin were all shown to be promising [720][721][722]. Similar to total artificial joints, both tribocorrosion and fretting corrosion were also found in dental implants [723].…”

Dental or tooth wear is a physiological process in the life cycle of teeth. Loss of the occlusal surface may cause excessive tooth wear. Several factors may contribute to tooth wear with different intensities and duration in the oral cavity. The oral cavity is generally compared to a tribological system to determine the various types of wear between teeth and restorative materials and assess the amount of dental wear. However, it is challenging to investigate in vitro and in vivo wear owing to the complexity of tooth wear; thus, a clear correlation between in vitro and in vivo data could not be established. This review is aimed at providing an insight into the etiology of tooth wear and tribological investigations in dentistry.
