Three-dimensional analytical models of three zirconia abutments with a titanium base and different zirconia margin shapes (i.e., chamfer, shoulder, and back-taper shapes) were prepared from CAD data and the digitized shape of physical models that were obtained using a laser 3D digitizer. In the first analysis, a mastication force of 500 N was applied to the top surface of the zirconia sleeve, and the maximum principle stress in the zirconia sleeve was extracted as the main risk factor for zirconia sleeve fracture. The loading direction was changed to examine the effect of the tangential force acting on the denture. In the second analysis, the angle of inclination of the zirconia margin with the chamfer and back-taper shapes was changed from -20 to 40 degrees, and its effect on the maximum principle stress in the zirconia sleeve was estimated. The results indicated that a marked tensile stress was exerted in zirconia if the sleeve margin had the chamfer shape, since the thin zirconia margin was extended by the indentation of the tapered titanium base. The value of the maximum principle stress was highly dependent on the loading direction, and it rose with increasing the loading angle to the implant axis. The maximum principle stress could be reduced by applying the shoulder shape to the zirconia margin despite the loading direction. The back-taper shape was also effective to reduce the maximum principle stress if the loading angle was less than 10 degrees. However, it exerted a higher stress if the loading angle exceeded 20 degrees. The advantage of a shoulder-shaped zirconia margin to improve the fracture strength could be confirmed by a quasi-static loading experiment to assess the physical models..

However, detailed mechanisms of these tribological processes have not been clarified yet. The present study aims on the effect of adsorbed protein film on frictional behaviour of metal/polyethylene contact pair. Reciprocating pin-on-plate test was conducted, while the CoCrMo pin was sliding against UHMWPE plate. The contact was lubricated by various solutions of albumin and γ-globulin solved in PBS. After the friction test, the thickness of adsorbed film was evaluated using spectroscopic ellipsometry. Structure of the adsorbed proteins was later examined by FT-IR. The results showed that at low sliding speed equal to 10 mm/s, there was a linear correlation between the friction coefficient and the thickness of the adsorbed protein film. An increase of friction was thus accompanied by the evolution of protein film. In that case, both proteins undergone substantial conformational changes, losing their original structure. On the contrary, proteins could sustain their secondary structure to some extent at higher sliding speed (50 mm/s), when different behaviour of the both proteins could be observed. This phenomenon was attributed to different structure of albumin and γ-globulin in its native state. It might be concluded that friction coefficient of metal-on-polyethylene joint prosthesis is influenced by protein content, as well as kinematic conditions, since the sliding conditions have a certain effect on both the adsorbed film formation and structure of the adsorbed molecules..

Upregulative effects of mechanical stimuli on extracellular matrix (ECM) biosynthesis of chondrocytes have been utilized in the cartilage tissue for regenerative tissue engineering. However, dynamic functionalities of these regenerated cartilages were lacked compared with the natural arthrodial cartilage. Natural synovial joint surfaces are contacting and sliding each other. As a result, the loading condition applied to the cartilage tissue is not simple. Under the contact between surfaces, non-uniform stress distribution is exerted in the cartilage tissue. The shear stress at contact area is highly depended on the distance from the surface. Moreover, the surface region is exposed to larger shear stress compared with the deep region. We hypothesized that high stress in surface region may stimulate chondrocytes selectively and establish anisotropic structure in elaborated tissue. In this study, the relative motion between cartilage surfaces in a synovial joint is simulated by the rolling-sliding motion of the roller on the cultured chondrocyte-agarose construct. Then, we investigated effects on the ECM distribution and morphology of regenerated cartilage tissue..

Here we observed the morphology of wear particles generated during a reciprocating wear test and assessed macrophage immune responses by applying hydrogel wear particles. As a result, PVA-CD had a significantly lower total amount of wear than did PVA-FT. The size distributions of PVA-FT and -CD wear particles were similar. Most of the particles were nanoparticles up to approximately 50 nm in diameter. Considering the particle volume distribution, there were very few micron- and submicron-sized wear particles around 1 μm in diameter. In SEM observations of dried PVA wear particles, both distributions of wear particles of PVA-FT and -CD were similar. Micron-sized wear particles were chiefly formed by close packing of 20- to 50-nm-sized particles. Biochemical and immunological evaluations revealed no cytotoxic effects of wear particles on macrophages. Cytokine synthesis of both wear particle-stimulated groups was significantly lower than that of the lipopolysaccharide-stimulated positive control. Therefore, it is suggested that PVA wear particles do not affect the macrophage immune response..

Yoshinori Sawae, Biotribology of Natural Synovial Joint and Joint Prosthesis, The Japan Society of Mechanical Engineers Hokkaido Branch “Biomechanics Research Meeting” 29th Seminar, 2017.07, The word “Biotribology” was defined in 1971 to embrace “all aspects of tribology (friction, wear and lubrication) concerned with biological systems”. It covers many events encountered during our daily life as research interests, for example, friction between a glass and fingers for gripping, wear of teeth during brushing and so on. Among them, the lubrication mechanism of natural synovial joint is a popular research topic in biotribology. The smooth movement of human diarthrodial joints has attracted huge interests of researchers not only in biomedical filed but also in engineering field, since the typical friction coefficient of synovial joints is extremely lower, around 0.001, compared with that of man-made bearing systems, those friction coefficient is usually 0.1 to 0.01. The wear of prosthetic joint materials is another important issue for biotribology. Metal ions and polymer wear particles released from sliding surfaces of joint prosthesis implanted in human body are usually very toxic and exert adverse reactions in the surrounding living tissue Therefore, it is recognized as a main factor restricting the lifetime of current artificial joints. This presentation attempts to present recent progress of biotribology research on the natural synovial joint and joint replacements..

In these valves, polymer composites are used as sealing materials and sliding against metal counter faces under the gaseous hydrogen. Their friction and wear behavior in the hydrogen environment should be important as well as their hydrogen sealing ability, since the increased friction and excessive wear can induce the efficiency degradation and increase in the system maintenance cost. In this study, the gas sealing ability and wear behavior of polymer composites in gaseous hydrogen were evaluated as the index of sealing parts performance. The experimental results showed that differences in the filler materials of PTFE composites and the metal surface roughness affect both hydrogen sealing ability and volumetric wear rate..
86.	Yoshinori Sawae, Takashi Morioka, Ryohei Oide, Effect of Phospholipids on Wear of Ultra-High Molecular Weight Polyethylene, 39th Leeds-Lyon Symposium on Tribology, 2012.09, Ultra-high molecular weight polyethylene (UHMWPE) components of joint prostheses release very fine wear particles during articulation. These fine wear particles can cause serious adverse reactions to surrounding living tissues and finally induce aseptic loosening of joint components [1]. Therefore, the wear behaviour of implanted UHMWPE and characteristics of released wear particles are now recognized as decisive factors for the durability and long term survivorship of artificial joints. However, the in vivo wear mechanism of UHMWPE and the formation process of fine polyethylene wear particles have not yet been fully understood. In this study, the effects of two different kinds of phospholipids, both of which are contained in natural synovial fluid, on the volumetric wear rate of UHMWPE and morphological characteristics of released polyethylene wear particles were examined experimentally to gain an understanding of the in vivo wear mechanism of UHMWPE. The multidirectional sliding pin-on-plate wear tester was employed to reproduce the “cross-shear” sliding condition of the artificial hip joint articulation in a laboratory wear test..
87.	Yoshinori Sawae, Kazuhiro Nakashima, Seido Yarimitsu, Teruo Murakami, Biotribology in Natural Synovial Joint and Joint Prosthesis, Malaysia-Japan Tribology Meeting, 2012.08, “Biotribology” is the word indicating “all aspects of tribology concerned with biological systems [1]”. Especially, friction, wear and lubrication in natural synovial joint and joint prosthesis have been major research subjects in the biotribology field. In natural synovial joints, highly sophisticated lubrication mechanisms are operating during daily activities and friction coefficient is always kept low, typically around 0.01 or less, even under severe dynamic loading and complicated sliding motions. The wear is also very small enough to be able to keep the tissue integrity for seven to eight decades. Therefore, joint lubrication mechanisms in human body have been attracting the interest of many tribologists. The tribological characteristics of joint prosthesis; a man-made bearing system for replacing diseased natural joint, is another important topic in biotribology since the wear of bearing materials used in articulating components of joints have been recognized as the main cause of early prosthesis loosening. This presentation reviews recent findings from biotribology researches on natural synovial joint and artificial joint conducted in Department of Mechanical Engineering and Research Center for Advanced Biomechanics, Kyushu University..

The multidirectional sliding pin-on-plate wear tester is employed to reproduce the “cross-shear” sliding condition of the artificial hip joint articulation in a laboratory wear test. In this study, most interests were focused on the effects of lipid molecules with different molecular structures..
