Addition of Ag to the ceramic film enhanced its antibacterial activity [ 258 , 259 , 260 ]. The majority of studies of total hip replacement have shown improved fixation with a decrease in the number of radiolucencies around an HA coated titanium alloy femoral component [28, 29], although others have shown no differences between coated and uncoated implants [30, 31].Published: 20 June 2022. (This is skipped in a partial hip replacement).Coating an implant with HA can be performed in numerous ways, from plasma spraying, dip coating, electrochemical deposition and more. HA has chemically and crystallographically . 2) significantly reduce the time required for osseointegration and provide osteogenesis, i. Thermal spraying of HAP on implant devices can be compared with plasma spray coating technique, having the advantage of high deposition rate and low cost [82], [83].
