Ua lilo ʻo Titanium i koho mua no nā implants ʻoki kino ma ke kahua lapaʻau ma muli o kona mau waiwai maikaʻi loa a me ka biocompatibility. I nā makahiki i hala iho nei, ua piʻi nui ka hoʻohana ʻana o ka titanium i nā implants orthopedic a me nā niho, a me nā ʻano mea lapaʻau like ʻole. Hiki ke hoʻopili ʻia kēia piʻi ʻana o ke kaulana i nā waiwai kūikawā o ka titanium e like me ka ikaika, ke kūpaʻa i ka pala a me ka hoʻohālikelike ʻana me ke kino kanaka. Ma kēia ʻatikala, e ʻimi mākou i nā kumu i lilo ai ka titanium i mea koho no nā implants lapaʻau, a me nā pae kikoʻī a me nā māka e hōʻoiaʻiʻo ai i ke kūpono o ka titanium no ia mau noi.
ʻO kekahi o nā kumu nui no ka hoʻohana nui ʻia ʻana o ka titanium i nā implants lapaʻau ʻo ia kona biocompatibility. Ke manaʻo ʻia he biocompatibility kahi mea, ʻo ia hoʻi ua ʻae maikaʻi ʻia e ke kino a ʻaʻole ia e hoʻoulu i nā hopena pale maikaʻi ʻole. ʻO ka biocompatibility o Titanium ma muli o kona hiki ke hana i kahi papa oxide pale lahilahi ma luna o kona ʻili ke hōʻike ʻia i ka oxygen. Hoʻolilo kēia papa oxide i ka titanium inert a kū i ka corrosion, e hōʻoiaʻiʻo ana ʻaʻole ia e pane me nā wai kino a i ʻole nā ʻiʻo. ʻO ka hopena, ʻaʻole hiki i nā implants titanium ke hoʻoulu i ka mumū a i ʻole ka hōʻole ʻana, e lilo ia i koho palekana a hilinaʻi hoʻi no nā noi lapaʻau.
Ma waho aʻe o ka biocompatibility, loaʻa i ka titanium kahi lakio ikaika-a-kaumaha maikaʻi loa, he mea koʻikoʻi ia no nā implants e pono e kū i nā pilikia mechanical a me nā ʻeha o ke kino. Inā no nā implants ʻoki kino, nā mea hoʻopaʻa orthopedic a i ʻole nā implants niho, pono e lawa ka ikaika o nā mea i hoʻohana ʻia e kākoʻo i nā hana o ke kino me ka ʻole o ka nui loa. ʻO ka ikaika kiʻekiʻe o ka Titanium a me ka haʻahaʻa haʻahaʻa e lilo ia i mea kūpono no ia mau noi, e hāʻawi ana i ke kākoʻo kūkulu pono me ka ʻole o ka hoʻohui ʻana i ke kaumaha a i ʻole ke kaumaha i ke kino.
Eia kekahi, he kūpaʻa maikaʻi loa ka titanium i ka pala, he mea koʻikoʻi ia no nā implants e noho mau ana i loko o ke kino no ka manawa lōʻihi. He pala loa ke kaiapuni physiological o ke kino, a hiki i nā wai kino like ʻole a me nā electrolytes ke hoʻohaʻahaʻa i nā implants metala i ka hala ʻana o ka manawa. Hana ka papa oxide kūlohelohe o Titanium ma ke ʻano he pale pala, e hōʻoiaʻiʻo ana i ke kūpaʻa lōʻihi a me ka pono o ka implant i loko o ke kino. He mea nui loa kēia kūpaʻa pala no nā implants i nā noi amo ukana, e like me nā pani ʻūhā a me ke kuli, kahi e pono ai ka mea e kū i ke kaumaha mechanical mau me ka ʻole o ka pala.
He mau koi koʻikoʻi ko kekahi mau hui honua no nā kūlana kikoʻī a me nā papa o ka titanium i hoʻohana ʻia i nā implants lapaʻau e hōʻoia i ka maikaʻi a me ka palekana o kēia mau mea. Ua hoʻomohala ka American Society for Testing and Materials (ASTM) i nā kūlana e like me ASTM F136 a me ASTM F67 e wehewehe ana i ka haku mele kemika, nā waiwai mechanical, a me nā ʻano hoʻāʻo no ka titanium papa lapaʻau. Hōʻoia kēia mau kūlana e hoʻokō ka titanium i hoʻohana ʻia i nā implants i nā kūlana e pono ai no ka biocompatibility, ka ikaika, a me ke kūpaʻa ʻana i ka pala.
Eia kekahi, ua wehewehe ka International Organization for Standardization (ISO) i nā papa kikoʻī o ka titanium, e like me ISO 5832-2, ISO 5832-3, a me ISO 5832-11, i hoʻohana pinepine ʻia i nā implants orthopedic a me nā niho. Hoʻākāka kēia mau kūlana ISO i nā koi no nā titanium alloys i hoʻohana ʻia i nā implants ʻokiʻoki, me ka haku mele ʻana, nā waiwai mechanical, a me ka hoʻāʻo biocompatibility. ʻO Ti6Al7Nb kahi titanium alloy kaulana no nā implants lapaʻau, e hoʻohui ana i ka ikaika kiʻekiʻe, biocompatibility a me ke kūpaʻa ʻana i ka corrosion no kahi ākea o nā mea hana implantable.
Loaʻa pinepine ka Titanium no nā implants lapaʻau ma ke ʻano o nā koʻokoʻo, nā uea, nā pepa a me nā papa. Hiki ke hoʻohana ʻia kēia mau ʻano like ʻole e hana i nā ʻano implants a me nā mea hana like ʻole, mai nā wili iwi a me nā papa a hiki i nā abutments niho a me nā cages spinal. ʻO ka versatility o ka titanium i nā ʻano like ʻole e hiki ai i nā mea hana ke hoʻopilikino i ka mea i nā hoʻolālā a me nā noi implan kikoʻī, e hōʻoiaʻiʻo ana e hoʻokō ka implant i nā kūlana hana mechanical a me biological e pono ai.
I ka hōʻuluʻulu manaʻo, ʻo ka maikaʻi loa o ka titanium biocompatibility, ka ikaika a me ke kūpaʻa i ka palaho e lilo ia i mea koho no nā implants lapaʻau. ʻO nā kūlana kikoʻī a me nā māka e like me ASTM F136, ASTM F67, ISO 5832-2/3/11 a me Ti6Al7Nb e hōʻoiaʻiʻo ana e hoʻokō ka titanium i hoʻohana ʻia i nā implants lapaʻau i nā koi koʻikoʻi a me ka palekana. Me kona hiki ke kū i ke kaiapuni physiological o ke kino a hāʻawi i ke kūpaʻa lōʻihi, ke hoʻomau nei ka titanium i kahi hana koʻikoʻi i ka hoʻolaha ʻana i ka ʻenehana implant lapaʻau a me ka hāʻawi ʻana i nā mea maʻi me nā hopena hilinaʻi a paʻa no nā ʻano pono orthopedic a me nā niho.
Ke alakaʻi ʻia nei mākou e kahi hui o nā ʻenekinia akamai a me nā loea ʻoihana me ka ʻoi aku o 20 mau makahiki o ka ʻike loea i ka hana ʻana i nā mea titanium kiʻekiʻe. Hoʻomaopopo mākou i ke ʻano kū hoʻokahi a me ka makamae o ke ola a ʻo kā mākou akeakamai ʻoihana e hana pū me kā mākou mea kūʻai aku e mālama i ke olakino kanaka me ka lawelawe kūikawā, ke kūlana kiʻekiʻe a me ke kumukūʻai kiʻekiʻe.
Welina mai e hui pū me nā haneli o nā mea kūʻai aku hauʻoli o Xinnuo e hana i nā huahana Titanium maikaʻi no ke ola olakino a hauʻoli hoʻi o ke kanaka.
