    <ns1:description language="sr">Ponašanje metalnih biomaterijala odreĊeno je u velikoj meri karakteristikama njihove površine,koje predstavljaju jedan od kljuĉnih faktora u interakcijama implanta sa okolnim tkivom. Zaoptimizaciju i poboljšanje biokompatibilnih i mehaniĉkih svojstava implanata ĉesto je neophodnamodifikacija površine. Ovakve metode, poznate kao površinski tretmani ili modifikacije, mogu sepodeliti u ĉetiri grupe: mehaniĉke, fiziĉke, hemijske i biološke površinske modifikacije...</ns1:description>
    <ns1:description language="en">The behaviour of metallic biomaterials is largely determined by the characteristics of their surface,which present one of the key factors in the interactions of the implant with the surrounding tissue.Surface modification is often necessary to optimize and improve the biocompatibility andmechanical properties of implants. Surface treatments or modifications can be classified into fourgroups: mechanical, physical, chemical and biological surface modifications...</ns1:description>
