“…Polyvinyl alcohol (PVA), which has the mechanical characteristics and good biocompatibility can be used to enhance the performance of a composite 7 . PVA is widely used to replace a damaged body tissue because it possesses a physic-chemical property, particularly it is an excellent bio-tribiological due to its slick surface, resistant to friction and wear 8 . Furthermore, PVA has good biocompatibility 9 .…”

The main objective of this study is to synthesize a composite of hydroxyapatite (HAp)-chitosan-polyvinyl alcohol (PVA) and to evaluate its uses as bone filler. An injectable bone substitute (IBS) material is a suspension of bone filler which applied by injection to fill the gaps caused by osteoporosis. A hydroxyapatite used as the composite's component was synthesized from Tutut shell. The composite was made by mixing hydroxyapatite, chitosan and PVA to homogeneous followed by irradiation with gamma rays at 20 kGy. The composite was characterized by FTIR analysis, XRD, SEM, viscosity test, and cytotoxicity assay. The FTIR analysis showed the bond formation between hydroxyapatite and chitosan, which later formed cross linkages by the addition of PVA. The viscosity of the composite was 36dPa. The cytotoxicity assay (MTT assay) showed that the suspension is not toxic because the cell viability value was obtained at more than 50%. As a conclusion, the composite of HAp from tutut shell-chitosan-PVA is suitable to be used as an injectable bone substitute.

“…Although earlier studies focused primarily on the coefficient of friction associated with hydrogel articulations, the current consensus is that the ability to maintain a low coefficient of friction alone does not imply adequate wear resistance (Freeman et al, 2000;Katta et al, 2007;Yasuda et al, 2005). Nevertheless, quantifying the wear rate of swellable materials is problematic (Bigsby et al, 1998;Freeman et al, 2000;Suciu et al, 2004;Yasuda et al, 2005) and no established, standardized methods for characterizing the wear behavior of hydrogel articulations have yet been developed (Yasuda et al, 2005).…”

“…Gravimetric measurement, which is widely used to quantify polymer wear loss, has been utilized in some studies to characterize the wear properties of swellable materials based on wet weights (Bavaresco et al, 2008;Suciu et al, 2004). Suciu et al (2004) monitored the progression of wear of PVA hydrogels for up to 0.1 million cycles and reported fluctuating wear factors.…”

“…Suciu et al (2004) monitored the progression of wear of PVA hydrogels for up to 0.1 million cycles and reported fluctuating wear factors. Since wet weighing does not allow differentiation between the mass change caused by fluid movement as opposed to worn mass, it is not accurate when testing swellable materials (Covert, 2003;Suciu et al, 2004).…”
