Titanium yave sarudzo yekutanga yekuvhiya ma implants mumunda wekurapa nekuda kwehunhu hwayo hwakanaka uye biocompatibility. Mumakore achangopfuura, kushandiswa kwetitanium mumapfupa emapfupa uye mazino, pamwe chete nemhando dzakasiyana-siyana dzemishonga, yakawedzera zvakanyanya. Uku kuwedzera kukurumbira kunogona kuverengerwa kune yakasarudzika yetitanium senge simba, corrosion resistance uye kuenderana nemuviri wemunhu. Muchinyorwa chino, tichaongorora zvikonzero nei titanium yave chinhu chesarudzo chekudyara kudyara, pamwe nemaitiro chaiwo uye mamakisi anovimbisa kukodzera kwetitanium kune mafomu akadaro.
Chimwe chezvikonzero chikuru chekushandiswa kwakapararira kwetitanium mukudyara kwekurapa ndeye biocompatibility yayo. Kana chinhu chichionekwa sechinhu chinopindirana, zvinoreva kuti chinotenderwa zvakanaka nemuviri uye hachikonzeri maitiro akashata ekudzivirira. Titanium's biocompatibility imhaka yekugona kwayo kuumba yakatetepa inodzivirira oxide layer pamusoro payo kana yasangana neokisijeni. Iyi oxide layer inoita kuti titanium inert uye isingaite ngura, ichiona kuti haizopindirana nemvura yemuviri kana matishu. Nekuda kweizvozvo, ma implants etitanium haanyanyi kukonzera kuzvimba kana kurambwa, zvichiita kuti ive sarudzo yakachengeteka uye yakavimbika yezvikumbiro zvekurapa.
Pamusoro peiyo biocompatibility, titanium ine yakanakisa simba-ku-huremu reshiyo, iyo yakakosha kune ma implants ayo anofanirwa kumirisana nemakanika kushushikana uye kuomarara kwemuviri. Zvingave zvezvigadziriso zvekuvhiya, zvekugadzirisa mapfupa kana mazino, zvinhu zvinoshandiswa zvinofanira kunge zvakasimba zvakakwana kuti zvitsigire mabasa emuviri pasina kunyanya kuwanda. Titanium yakakwira simba uye yakaderera density inoita kuti ive chinhu chakanakira maapplication akadaro, ichipa iyo inodiwa yerutsigiro yerutsigiro pasina kuwedzera huremu husina basa kana kushushikana kumuviri.
Uye zvakare, titanium ine yakanakisa corrosion resistance, iyo yakakosha kune ma implants anoramba ari mumuviri kwenguva yakareba. Iyo physiological nharaunda yemuviri inoparadza zvakanyanya, uye dzakasiyana siyana dzemvura dzemuviri uye electrolytes zvinogona kukonzera simbi inodyarwa kudzikira nekufamba kwenguva. Titanium's natural oxide layer inoita sechivharo chekuora, ichivimbisa kugadzikana kwenguva refu uye kutendeseka kweiyo inodyarwa mumuviri. Uku kushora kwegora kunonyanya kukosha kune ma implants mukutakura-kutakura maapplication, akadai sehudyu nemabvi kutsiva, uko izvo zvinhu zvinofanirwa kutsungirira nguva dzose mechanical kusagadzikana pasina kushatisa.
Masangano akati wandei epasirese ane zvakaomesesa zvinodikanwa kune chaiwo mwero uye mamakisi etitanium anoshandiswa mune zvekurapa maimplants kuti ave nechokwadi chemhando uye kuchengetedzeka kwezvinhu izvi. Sangano reAmerican Society for Testing and Materials (ASTM) rakagadzira zviyero zvakaita seASTM F136 uye ASTM F67 inotsanangura kuumbwa kwemakemikari, magadzirirwo emagetsi, uye nzira dzekuyedza dzegiredhi rekurapa titanium. Aya mazinga anovimbisa kuti titanium inoshandiswa mumaimplants inosangana nezvinodiwa zvebiocompatibility, simba, uye corrosion kuramba.
Pamusoro pezvo, International Organisation for Standardization (ISO) inotsanangura magiredhi chaiwo etitanium, akadai se ISO 5832-2, ISO 5832-3, uye ISO 5832-11, ayo anowanzoshandiswa mukugadzirwa kwemapfupa nemazino. Aya maISO mazinga anotsanangura zvinodikanwa zvetitanium alloys anoshandiswa mukuvhiya implants, kusanganisira kuumbwa, michina zvivakwa, uye biocompatibility kuyedzwa. Ti6Al7Nb inozivikanwa zvikuru titanium alloy yemishonga inodyarwa, ichibatanidza simba guru, biocompatibility uye corrosion resistance kune zvakasiyana-siyana zvezvigadziri.
Titanium yekumisikidzwa kwekurapa inowanikwa mumhando yetsvimbo, waya, mashiti uye ndiro. Aya mafomu akasiyana anogona kushandiswa kugadzira marudzi akasiyana-siyana ekudyara nemidziyo, kubva pamapfupa screws uye mahwendefa kusvika kumazino abutments uye spinal cages. Iko kuita kwakasiyana-siyana kwetitanium mumhando dzakasiyana-siyana kunobvumira vagadziri kuti vagadzirise zvinhu kune chaiwo madhizaini ekudyara uye mashandisirwo, kuve nechokwadi chekuti implant inosangana neinodiwa mechaniki uye biological kuita maitiro.
Muchidimbu, titanium yakanakisa biocompatibility, simba uye corrosion kuramba inoita kuti ive chinhu chesarudzo chekudyara. Yakanangana mwero nemagiredhi akadai seASTM F136, ASTM F67, ISO 5832-2/3/11 uye Ti6Al7Nb inova nechokwadi chekuti titanium inoshandiswa mukuiswa mukurapa inosangana nekuomarara kwemhando uye kuchengetedza zvinodiwa. Nekukwanisa kwayo kumirisana nemamiriro emuviri wemuviri uye kupa kugadzikana kwenguva refu, titanium inoramba ichiita basa rakakosha mukusimudzira tekinoroji yekusima kwekurapa uye kupa varwere mhinduro dzakavimbika, dzakasimba dzezvakasiyana siyana zvemapfupa uye mazino.
Isu tinotungamirwa neboka revanyanzvi mainjiniya uye nyanzvi dzeindasitiri vane makore anopfuura makumi maviri ehunyanzvi ruzivo mukugadzira yakakwirira-yekupedzisira titanium zvinhu. Isu tinonzwisisa kusarudzika uye kukosha kwehupenyu uye uzivi hwebhizinesi redu ndehwekushanda nevatengi vedu kutarisira hutano hwevanhu nesevhisi yakasarudzika, yemhando yepamusoro uye yakakosha.
Tikugashirei Kujoina mazana evatengi vaXinnuo vanofara kugadzira zvigadzirwa zveTitanium zvehutano uye hupenyu hunofadza hwemunhu.
