I-Titanium ibe yisinqumo sokuqala sokufakelwa kokuhlinzwa emkhakheni wezokwelapha ngenxa yezakhiwo zayo ezinhle kakhulu kanye nokuhambisana kwayo nezinto eziphilayo. Eminyakeni yamuva nje, ukusetshenziswa kwe-titanium ekufakweni kwamathambo namazinyo, kanye nezinhlobo ezahlukene zamadivayisi ezokwelapha, kukhule kakhulu. Lokhu kwanda kokuthandwa kungabangelwa yizakhiwo ezihlukile ze-titanium ezifana namandla, ukumelana nokugqwala kanye nokuhambisana nomzimba womuntu. Kulesi sihloko, sizohlola izizathu zokuthi kungani i-titanium ibe yinto ekhethwayo yokufakelwa kwezokwelapha, kanye nezindinganiso ezithile kanye namabanga aqinisekisa ukufaneleka kwe-titanium kulezo zicelo.
Esinye sezizathu eziyinhloko zokusetshenziswa kabanzi kwe-titanium ezifakelweni zezokwelapha ukuhambisana kwayo nezinto eziphilayo. Uma into ibhekwa njengehambisana nezinto eziphilayo, kusho ukuthi ibekezelelwa kahle ngumzimba futhi ayibangeli ukusabela okubi kwamasosha omzimba. Ukuhambisana kwezinto eziphilayo kwe-Titanium kungenxa yekhono layo lokwakha ungqimba oluncane lwe-oxide oluvikelayo ebusweni bayo uma luvezwa umoya-mpilo. Lolu ngqimba lwe-oxide lwenza i-titanium ingangeni futhi imelane nokugqwala, okuqinisekisa ukuthi ngeke isabele ngoketshezi lomzimba noma izicubu. Ngenxa yalokho, izifakelo ze-titanium cishe azibangeli ukuvuvukala noma ukwenqatshwa, okwenza kube ukukhetha okuphephile nokuthembekile kwezicelo zezokwelapha.
Ngaphezu kokuhambisana kwezinto eziphilayo, i-titanium inesilinganiso esihle kakhulu samandla nesisindo, okubaluleke kakhulu kuma-implant okumele amelane nokucindezeleka komzimba. Kungakhathaliseki ukuthi ama-implant okuhlinzwa, amadivayisi okuqinisa amathambo noma ama-implant amazinyo, izinto ezisetshenziswayo kumele zibe namandla ngokwanele ukusekela imisebenzi yomzimba ngaphandle kokuba zinkulu kakhulu. Amandla aphezulu kanye nobukhulu obuphansi be-Titanium kwenza kube yinto efanelekile yokusetshenziswa okunjalo, ihlinzeka ngokusekelwa kwesakhiwo okudingekayo ngaphandle kokwengeza isisindo esingadingekile noma ukucindezeleka emzimbeni.
Ngaphezu kwalokho, i-titanium inokumelana okuhle kakhulu nokugqwala, okubaluleke kakhulu kuma-implant ahlala emzimbeni isikhathi eside. Indawo ezungezile yomzimba igqwala kakhulu, futhi uketshezi oluhlukahlukene lomzimba kanye nama-electrolyte kungabangela ukuthi ama-implant ensimbi awohloke ngokuhamba kwesikhathi. Ungqimba lwe-oxide yemvelo ye-Titanium lusebenza njengesivikelo sokugqwala, okuqinisekisa ukuzinza kwesikhathi eside kanye nobuqotho be-implant emzimbeni. Lokhu kumelana nokugqwala kubaluleke kakhulu kuma-implant ezisetshenziswayo zokuthwala umthwalo, njengokushintsha izinqe namadolo, lapho izinto kufanele zibhekane nokucindezeleka okuqhubekayo kwemishini ngaphandle kokuwohloka.
Izinhlangano eziningana zamazwe ngamazwe zinezidingo eziqinile zezindinganiso ezithile kanye namazinga e-titanium asetshenziswa ezifakelweni zezokwelapha ukuqinisekisa ikhwalithi nokuphepha kwalezi zinto. I-American Society for Testing and Materials (ASTM) ithuthukise amazinga afana ne-ASTM F136 kanye ne-ASTM F67 achaza ukwakheka kwamakhemikhali, izakhiwo zemishini, kanye nezindlela zokuhlola ze-titanium yezinga lezokwelapha. Lezi zindinganiso ziqinisekisa ukuthi i-titanium esetshenziswa ezifakelweni ihlangabezana nezindinganiso ezidingekayo zokuhambisana kwezinto eziphilayo, amandla, kanye nokumelana nokugqwala.
Ngaphezu kwalokho, i-International Organisation for Standardization (ISO) ichaza amazinga athile e-titanium, njenge-ISO 5832-2, ISO 5832-3, kanye ne-ISO 5832-11, avame ukusetshenziswa ekufakweni kwamathambo namazinyo. Lezi zindinganiso ze-ISO zichaza izidingo zama-alloy e-titanium asetshenziswa ekufakweni kokuhlinzwa, okuhlanganisa ukwakheka, izakhiwo zemishini, kanye nokuhlolwa kokuhambisana kwezinto eziphilayo. I-Ti6Al7Nb iyi-alloy ye-titanium eyaziwayo yezifakelo zezokwelapha, ehlanganisa amandla aphezulu, ukuhambisana kwezinto eziphilayo kanye nokumelana nokugqwala kwezinhlobo eziningi zamadivayisi afakelwayo.
I-Titanium yezifakelo zezokwelapha ivame ukutholakala ngesimo sezinduku, izintambo, amashidi namapuleti. Lezi zinhlobo ezahlukene zingasetshenziswa ukwenza izinhlobo ezahlukene zezifakelo namadivayisi, kusukela kuzikulufo zamathambo namapuleti kuya ezisekelweni zamazinyo kanye nezikheji zomgogodla. Ukuguquguquka kwe-titanium ngezindlela ezahlukene kuvumela abakhiqizi ukuthi bahlele izinto ngokuvumelana nemiklamo ethile kanye nezinhlelo zokusebenza zezifakelo, ukuqinisekisa ukuthi isifakelo sihlangabezana nezindinganiso zokusebenza ezidingekayo zemishini kanye nezebhayoloji.
Ngamafuphi, ukuhambisana kahle kwe-titanium, amandla kanye nokumelana nokugqwala kwenza kube yinto ekhethwayo yokufakelwa kwezokwelapha. Izindinganiso ezithile kanye namazinga afana ne-ASTM F136, ASTM F67, ISO 5832-2/3/11 kanye ne-Ti6Al7Nb aqinisekisa ukuthi i-titanium esetshenziswa ekufakweni kwezokwelapha ihlangabezana nezidingo eziqinile zekhwalithi kanye nokuphepha. Njengoba ikwazi ukumelana nendawo yomzimba yomzimba futhi inikeze ukuzinza kwesikhathi eside, i-titanium iyaqhubeka nokudlala indima ebalulekile ekuthuthukiseni ubuchwepheshe bokufakelwa kwezokwelapha kanye nokunikeza iziguli izixazululo ezinokwethenjelwa nezihlala isikhathi eside zezidingo ezahlukahlukene zamathambo namazinyo.
Siholwa yiqembu lonjiniyela abanolwazi kanye nochwepheshe bemboni abaneminyaka engaphezu kwengu-20 yesipiliyoni sobuchwepheshe ekukhiqizeni izinto ze-titanium ezisezingeni eliphezulu. Siyaqonda ukuthi impilo iyingqayizivele futhi iyigugu futhi ifilosofi yethu yebhizinisi iwukusebenza namakhasimende ethu ukunakekela impilo yabantu ngensizakalo evelele, ikhwalithi ephezulu kanye nenani eliphezulu.
Siyakwamukela ukuze ujoyine amakhulu amakhasimende ajabule e-Xinnuo ukuze ukhiqize imikhiqizo ye-Titanium esezingeni eliphezulu ukuze umuntu aphile impilo enempilo nejabulisayo.
