Purpose The study was intended to create a uniform zirconia layer even on the surface of complex structures via atomic layer deposition (ALD). The impact of crystalline zirconia deposited by ALD on bacterial adhesion and osteoblast viability was assessed via surface treatment of dental implants. Methods Amorphous zirconia was deposited using an atomic layer deposition reactor (Atomic Classic, CN1, Hwaseong, Korea) on titanium discs. Heating the samples at 400°C resulted in crystallization. Samples were divided into three groups: the control group, the group carrying amorphous ALD-zirconia (Z group), and the heat-treated group following zirconia ALD deposition (ZH group).The surface of each sample was analyzed, followed by the assessment of adhesion of Streptococcus mutans and Porphyromonas gingivalis , and viability and differentiation of MC3T3-E1 cells. Results The adhesion of S. mutans and P. gingivalis was significantly reduced in the Z and ZH groups compared with the control group (P < 0.05). The viability of MC3T3-E1 cells was significantly increased in the ZH group compared with the control group (P < 0.001), while no significant differences were observed in the Z group (P > 0.05). Differentiation of MC3T3-E1 cells showed a marginally significant increase in the ZH group compared with the control group (P < 0.1), while no significant differences were found in the Z group (P > 0.1). Conclusion Compared with the pure titanium group, the groups that were coated with zirconia via ALD showed a decreased adhesion of S. mutans during the early stages of biofilm formation and P. gingivalis adhesion inducing peri-implantitis, and an increase in MC3T3-E1 cell viability and differentiation. The findings indicate the possibility of treating the implant surface to reduce peri-implantitis and improve osseointegration.

The friction and wear behaviors of cartilage replacement materials against articular cartilage are considered essential characteristics that determine the function and performance of the replacement. Previous studies have often been conducted under a reciprocal linear motion, while a cross-shear motion has been shown to widely exist in joints. The difference resulting between cross-shear motion and reciprocal linear motion, and the effect of bearing surface roughness on the frictional and wear behaviors of cartilage should be further investigated. In this study, experimental tribology investigations were conducted under the cross-shear motion for articular cartilage against commonly used three replacement materials, including high cross-linked polyethylene (HXLPE), polyether ether ketone (PEEK), and cobalt-chromium molybdenum alloy (CoCrMo). The experimental results showed that there was no significant difference in friction and wear behavior between cross-shear and reciprocal linear motion. For the implants with low surface roughness, the water contact angle of the bearing surface affected the friction and wear behaviors of the cartilage, while for the implants with high rough surfaces, the surface roughness of the material affected the friction and wear behaviors of the cartilage. The damage of cartilage under cross-shear motion mainly consisted of deformations and accumulations. This phenomenon was especially evident at high roughness. Of the three bearing materials considered, PEEK was more suitable for osteochondral implants.

“…Zirconia (ZrO 2 ) ceramic, as one of the most important oxide ceramics, not only in possession of biosafety (no cytotoxicity), but also can exist stably in the oral environment without releasing harmful impurities and degradation [12][13][14][15][16]. In comparison with alumina (Al 2 O 3 ) ceramic, ZrO 2 ceramic has more excellent mechanical properties, which can meet the requirements of higher compressive strength and hardness of dental crown [17][18][19][20][21].…”

In-situ mullite toughened 3Y-TZP composite ceramic (mullite/3Y-TZP) with excellent mechanical properties was fabricated by gel-casting. The cytotoxicity of mullite/3Y-TZP was determined by both extract and direct contact methods, and the results indicated that mullite/3Y-TZP had no acute cytotoxicity. Furthermore, the tribological properties of the tooth enamel sliding against mullite/3Y-TZP in artificial saliva were investigated by using the pin-on-plate friction method. The friction coefficient (μ) between the two friction samples was about 0.464 with a stable friction process, and both of them showed slight wear. Analysis of the wear surface and debris demonstrated that the tooth enamel mainly suffered from fatigue wear accompanied by mild adhesive wear, while mullite/3Y-TZP showed slight abrasive wear. This result indicated that mullite/3Y-TZP had good wear resistance and showed potential applications in dental material.
