Kua riro te titanium hei whiringa tuatahi mō ngā tāpiringa pokanga i roto i te ao hauora nā ōna āhuatanga pai me te hototahi ki te koiora. I ngā tau tata nei, kua tino piki ake te whakamahinga o te titanium i roto i ngā tāpiringa wheua me ngā niho, tae atu ki ngā momo taputapu hauora. Ko tēnei pikinga o te rongonui ka taea te kī ko ngā āhuatanga ahurei o te titanium pēnei i te kaha, te ātete ki te waikura me te hototahi ki te tinana tangata. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā take i riro ai te titanium hei rauemi whiriwhiri mō ngā tāpiringa hauora, tae atu ki ngā paearu me ngā tohu motuhake e whakarite ana i te pai o te titanium mō aua tono.
Ko tētahi o ngā take matua mō te whakamahinga whānui o te titanium i roto i ngā tāpiringa hauora ko tōna hototahitanga koiora. Ina whakaarohia he hototahitanga koiora tētahi rauemi, ko te tikanga he pai te manawanui o te tinana, ā, kāore e puta he urupare ārai mate kino. Ko te hototahitanga koiora o te titanium nā tōna kaha ki te hanga i tētahi paparanga waikura angiangi tiaki i runga i tōna mata ina pāngia e te hāora. Ka meinga e tēnei paparanga waikura te titanium kia kore e tauhohe, kia ātete hoki ki te waikura, kia kore ai e tauhohe ki ngā wai o te tinana, ki ngā kiko rānei. Nō reira, he iti ake te tūponotanga o ngā tāpiringa titanium ki te puta he mumura, he whakakorenga rānei, ā, he kōwhiringa haumaru, he pono hoki mō ngā tono hauora.
Haunga te hototahitanga koiora, he tino pai te ōwehenga kaha-ki-taumaha o te titanium, he mea nui tēnei mō ngā whakaurunga me tu atu ki ngā ahotea ā-pūkaha me ngā taumahatanga o te tinana. Ahakoa mō ngā whakaurunga pokanga, ngā taputapu whakapiri wheua, ngā whakaurunga niho rānei, me kaha ngā rauemi e whakamahia ana hei tautoko i ngā mahi a te tinana me te kore e tino matotoru. Nā te kaha teitei me te iti o te mātotoru o te titanium he rauemi pai mō ēnei mahi, e whakarato ana i te tautoko hanganga e tika ana me te kore e tāpiri taumaha, ahotea rānei ki te tinana.
Hei tāpiritanga, he tino pai te ātete o te titanium ki te waikura, he mea nui tēnei mō ngā tāpiringa e noho roa ana i roto i te tinana. He tino waikura te taiao ā-tinana o te tinana, ā, ka taea e ngā wai me ngā irahiko o te tinana te whakararu i ngā tāpiringa whakarewa i roto i te wā. Ko te paparanga waikura tūturu o te titanium he ārai waikura, e whakarite ana i te pumau me te pono o te tāpiringa i roto i te tinana mō te wā roa. He mea tino nui tēnei ātete waikura mō ngā tāpiringa i roto i ngā tono kawenga, pērā i te whakakapinga hope me te turi, me tū atu te rauemi i te ahotea miihini tonu me te kore e pirau.
He maha ngā whakahaere o te ao e whai whakaritenga pakari ana mō ngā paerewa me ngā taumata motuhake o te titanium e whakamahia ana i roto i ngā whakaurunga hauora hei whakarite i te kounga me te haumaru o ēnei rauemi. Kua whakawhanakehia e te American Society for Testing and Materials (ASTM) ngā paerewa pēnei i te ASTM F136 me te ASTM F67 e whakaahua ana i te hanganga matū, ngā āhuatanga miihini, me ngā tikanga whakamātautau mō te titanium taumata hauora. Mā ēnei paerewa ka tutuki i te titanium e whakamahia ana i roto i ngā whakaurunga ngā paearu e tika ana mō te hototahitanga koiora, te kaha, me te ātete ki te waikura.
Hei tāpiritanga, e tautuhi ana te Whakahaere Paerewa o te Ao (ISO) i ngā momo motuhake o te titanium, pērā i te ISO 5832-2, ISO 5832-3, me te ISO 5832-11, e whakamahia whānuitia ana i roto i ngā whakaurunga wheua me ngā niho. E tautuhia ana e ēnei paerewa ISO ngā whakaritenga mō ngā koranu titanium e whakamahia ana i roto i ngā whakaurunga pokanga, tae atu ki te hanganga, ngā āhuatanga miihini, me te whakamātautau hototahitanga koiora. He koranu titanium rongonui te Ti6Al7Nb mō ngā whakaurunga hauora, e whakakotahi ana i te kaha teitei, te hototahitanga koiora me te ātete ki te waikura mō te whānuitanga o ngā taputapu ka taea te whakauru.
Ko te titanium mō ngā whakaurunga hauora e wātea ana i te nuinga o te wā i roto i te āhua o ngā tokotoko, ngā waea, ngā rau me ngā pereti. Ka taea te whakamahi i ēnei momo āhua rerekē hei hanga i ngā momo whakaurunga me ngā taputapu rerekē, mai i ngā tīwiri wheua me ngā pereti ki ngā tautoko niho me ngā kete tuaiwi. Nā te maha o ngā whakamahinga o te titanium i roto i ngā momo āhua rerekē ka taea e ngā kaihanga te whakarite i te rauemi ki ngā hoahoa me ngā tono whakaurunga motuhake, me te whakarite kia tutuki i te whakaurunga ngā paearu mahi ā-pūkaha me te koiora e hiahiatia ana.
Hei whakarāpopototanga, ko te pai o te hototahitanga koiora, te kaha me te ātete ki te waikura o te titanium e waiho ana hei rauemi whiriwhiri mō ngā whakaurunga hauora. Mā ngā paerewa me ngā tohu motuhake pēnei i te ASTM F136, ASTM F67, ISO 5832-2/3/11 me te Ti6Al7Nb ka whakarite kia tutuki i ngā titanium e whakamahia ana i roto i ngā whakaurunga hauora ngā whakaritenga kounga me te haumaru pakari. Nā tōna kaha ki te tu atu ki te taiao ā-tinana o te tinana me te whakarato i te pumau mō te wā roa, kei te whai wāhi tonu te titanium ki te whakatairanga i te hangarau whakaurunga hauora me te whakarato i ngā otinga pono, pakari hoki ki ngā tūroro mō ngā momo matea orthopedic me ngā niho.
