Medicinoje aliuminio oksido keramika da\u017eniau naudojama dirbtiniams kaulams, s\u0105nariams ir dantims gaminti. aliuminio oksido keramika pasi\u017eymi puikiu biologiniu suderinamumu, biologiniu inerti\u0161kumu, fizikiniu ir cheminiu stabilumu, dideliu kietumu ir atsparumu dilimui, tod\u0117l yra ideali med\u017eiaga dirbtiniams kaulams ir s\u0105nariams gaminti. Ta\u010diau ji turi t\u0173 pa\u010di\u0173 tr\u016bkum\u0173 kaip ir kitos keramin\u0117s med\u017eiagos, pavyzd\u017eiui, didel\u012f trapum\u0105, ma\u017e\u0105 atsparum\u0105 l\u016b\u017eiams, sud\u0117ting\u0105 apdirbimo technologij\u0105 ir sud\u0117ting\u0105 proces\u0105, tod\u0117l reikalingi tolesni tyrimai ir taikymas.<\/p>\n
Hidroksiapatitas pasi\u017eymi geru biologiniu suderinamumu ir biologiniu aktyvumu, o puikus jo poveikis kaul\u0173 laidumui patvirtintas daugeliu mokslini\u0173 tyrim\u0173 rezultat\u0173. \u0160iuo metu tai perspektyviausia keramin\u0117 dirbtinio kaulo med\u017eiaga. Ta\u010diau grynas hidroksiapatitas pasi\u017eymi prastomis mechanin\u0117mis savyb\u0117mis, tod\u0117l j\u012f sunku naudoti kaip med\u017eiag\u0105, pakei\u010dian\u010di\u0105 apkrov\u0105 ne\u0161ant\u012f kaul\u0105. Tikimasi, kad aliuminio oksido keramin\u0117 hidroksiapatito dirbtinio kaulo med\u017eiaga, sukepinta naudojant i\u0161lyd\u017eio plazmos technologij\u0105, taps idealia apkrov\u0105 ne\u0161an\u010dia kaul\u0173 med\u017eiaga, nes \u012fvedus dispersij\u0105 stiprinan\u010di\u0105 faz\u0119 Al2O3, pager\u0117s med\u017eiagos mechanin\u0117s savyb\u0117s. Taip ne tik i\u0161laikomas biologinis hidroksiapatito aktyvumas, bet ir pagerinamos med\u017eiagos mechanin\u0117s savyb\u0117s.<\/p>\n
aliuminio oksido keramikos hidroksiapatito dirbtinio kaulo med\u017eiaga turi daugyb\u0119 pritaikymo galimybi\u0173 \u017emogaus kaul\u0173 atstatymo srityje. Klinikin\u0117je ortopedin\u0117je chirurgijoje kaul\u0173 defektams taisyti da\u017enai reikia daug atstatom\u0173j\u0173 med\u017eiag\u0173. \u0160iuo metu \u012fprastos atstatomosios med\u017eiagos yra savi kaulai, alogeniniai kaulai ir dirbtin\u0117s sintetin\u0117s med\u017eiagos. Nors autologinio kaulo transplantacija neturi imuninio atmetimo ir pasi\u017eymi gerais rezultatais, jos med\u017eiag\u0173 pasirinkimas yra ribotas; alogeninio kaulo transplantacija yra linkusi \u012f imunin\u012f atmetim\u0105 ir pasi\u017eymi prastu atstatomuoju poveikiu; dirbtin\u0117s sintetin\u0117s med\u017eiagos, kurios i\u0161 esm\u0117s yra biologi\u0161kai suyran\u010dios med\u017eiagos, negali atstatyti defekto vietos. Tod\u0117l biomed\u017eiag\u0173, pasi\u017eymin\u010di\u0173 geromis fizikin\u0117mis ir biologin\u0117mis savyb\u0117mis, kaip kaul\u0173 transplantacijos med\u017eiag\u0173, paie\u0161ka tapo aktualia mokslini\u0173 tyrim\u0173 sritimi. \u0161ias problemas i\u0161sprend\u0117 aliuminio keramikos hidroksiapatito dirbtinio kaulo med\u017eiaga.
