I-Titanium iye yaba lukhetho lokuqala lokufakelwa kotyando kwicandelo lezonyango ngenxa yeempawu zayo ezintle kunye nokuhambelana kwezinto eziphilayo. Kwiminyaka yakutshanje, ukusetyenziswa kwe-titanium kwi-orthopedic kunye nokufakelwa kwamazinyo, kunye neentlobo zezixhobo zonyango, kuye kwanda kakhulu. Oku kunyuka kokuthandwa kunokubalelwa kwiipropathi ezikhethekileyo ze-titanium njengamandla, ukumelana nokubola kunye nokuhambelana nomzimba womntu. Kweli nqaku, siza kuhlolisisa izizathu zokuba kutheni i-titanium ibe yinto ekhethiweyo yokufakelwa kwezonyango, kunye neendlela ezithile kunye namabanga aqinisekisa ukufaneleka kwe-titanium kwizicelo ezinjalo.
Esinye sezizathu eziphambili zokusetyenziswa ngokubanzi kwe-titanium kukufakelwa kwezonyango kukuhambelana kwayo kwezinto eziphilayo. Xa into ithathwa njenge-biocompatible, ithetha ukuba inyamezelwa kakuhle ngumzimba kwaye ayibangeli ukusabela okungalunganga komzimba. I-biocompatibility ye-Titanium ibangelwa ukukwazi kwayo ukwenza umaleko obhityileyo okhuselweyo okhuselweyo kumphezulu wayo xa evezwe kwioksijini. Lo maleko weoksidi unika i-titanium inert kwaye imelane nokubola, iqinisekisa ukuba ayizukusabela ngolwelo lomzimba okanye izicubu. Ngenxa yoko, ukufakelwa kwe-titanium akunakwenzeka ukuba kubangele ukuvuvukala okanye ukugatywa, okwenza kube yinto ekhuselekileyo neyithembekileyo yokukhetha izicelo zonyango.
Ukongeza kwi-biocompatibility, i-titanium inomlinganiselo obalaseleyo wokomelela kubunzima, obubaluleke kakhulu kukufakelwa kwezinto ekufuneka zimelane noxinzelelo lomatshini kunye noxinzelelo lomzimba. Nokuba zezokufakelwa kotyando, izixhobo zokulungisa amathambo okanye izifakelo zamazinyo, izinto ezisetyenziswayo kufuneka zomelele ngokwaneleyo ukuxhasa imisebenzi yomzimba ngaphandle kokuba zininzi kakhulu. Amandla aphezulu e-Titanium kunye nokuxinana okuphantsi kwenza kube yinto efanelekileyo kwizicelo ezinjalo, ukubonelela ngenkxaso yesakhiwo esiyimfuneko ngaphandle kokongeza ubunzima obungeyomfuneko okanye uxinzelelo kumzimba.
Ukongeza, i-titanium inokumelana nokugqwesa okugqwesileyo, okubaluleke kakhulu kukufakelwa okuhlala emzimbeni ixesha elide. Ubume bomzimba bomzimba bugqwesa kakhulu, kwaye ulwelo oluhlukeneyo lomzimba kunye ne-electrolyte kunokubangela ukufakelwa kwentsimbi ukuthotywa ngokuhamba kwexesha. Umaleko we-oxide wendalo we-Titanium usebenza njengesithintelo somhlwa, uqinisekisa ukuzinza kwexesha elide kunye nokuthembeka kokufakelwa emzimbeni. Ukuxhatshazwa kwe-corrosion kubaluleke kakhulu kwi-implants kwizicelo ezithwala umthwalo, ezifana nokutshintshwa kwe-hip kunye namadolo, apho izinto eziphathekayo kufuneka zimelane noxinzelelo oluqhubekayo lomatshini ngaphandle kokuthotywa.
Imibutho emininzi yamazwe ngamazwe ineemfuno ezingqongqo zemigangatho ethile kunye namabakala e-titanium asetyenziswa kukufakelwa kwezonyango ukuqinisekisa umgangatho kunye nokhuseleko lwezi zinto. I-American Society for Testing and Materials (ASTM) iphuhlise imigangatho efana ne-ASTM F136 kunye ne-ASTM F67 echaza ukubunjwa kweekhemikhali, iipropathi zoomatshini, kunye neendlela zokuvavanya kwibakala lezonyango titanium. Le migangatho iqinisekisa ukuba i-titanium esetyenzisiweyo kwi-implants ihlangabezana nemigaqo efunekayo yokuhambelana ne-biocompatibility, amandla, kunye nokuxhathisa ukubola.
Ukongezelela, i-International Organization for Standardization (ISO) ichaza amabakala athile e-titanium, afana ne-ISO 5832-2, ISO 5832-3, kunye ne-ISO 5832-11, esetyenziswa ngokuqhelekileyo kwi-orthopedic kunye nokufakelwa kwamazinyo. Le migangatho ye-ISO ichaza iimfuno ze-titanium alloys ezisetyenziselwa ukufakelwa kotyando, kubandakanywa ukubunjwa, iimpawu zomatshini, kunye novavanyo lwe-biocompatibility. I-Ti6Al7Nb i-alloy ye-titanium eyaziwayo yokufakelwa kwezonyango, ukudibanisa amandla aphezulu, i-biocompatibility kunye nokuchasana nokugqwala kwezixhobo ezininzi ezifakelwayo.
I-Titanium yokufakelwa kwezonyango idla ngokufumaneka ngohlobo lweentonga, iingcingo, amaphepha kunye neepleyiti. Ezi fom zahlukeneyo zingasetyenziselwa ukwenza iintlobo ezahlukeneyo zokufakelwa kunye nezixhobo, ukusuka kwizikrufu zamathambo kunye neepleyiti ukuya kwii-abutments zamazinyo kunye ne-spinal cages. Ukuguquguquka kwe-titanium kwiifom ezahlukeneyo kuvumela abavelisi ukuba balungelelanise imathiriyeli kuyilo oluthile lokufakela kunye nokusetyenziswa, ukuqinisekisa ukuba ukufakelwa kuyahlangabezana nemilinganiselo yokusebenza efunekayo yoomatshini kunye nebhayoloji.
Ngamafutshane, i-biocompatibility ye-titanium egqwesileyo, amandla kunye nokumelana nomhlwa kuyenza ibe yeyona nto ikhethwayo kukufakelwa kwezonyango. Imigangatho ethile kunye namabakala afana ne-ASTM F136, i-ASTM F67, i-ISO 5832-2/3/11 kunye ne-Ti6Al7Nb iqinisekisa ukuba i-titanium esetyenziswa kukufakelwa kwezonyango ihlangabezana neemfuno ezingqongqo zomgangatho kunye nokhuseleko. Ngokukwazi ukumelana nommandla womzimba womzimba kunye nokubonelela ngokuzinza kwexesha elide, i-titanium iyaqhubeka idlala indima ebalulekileyo ekuqhubeleni phambili iteknoloji yokufakelwa kwezonyango kunye nokubonelela izigulane ezinokwethenjelwa, izisombululo ezizinzileyo kwiimfuno ezahlukeneyo zamathambo kunye namazinyo.
Sikhokelwa liqela leenjineli zesavvy kunye neengcali zoshishino ezineminyaka engaphezu kwama-20 yamava obugcisa ekwenzeni izinto ze-titanium eziphezulu. Siyakuqonda ukohluka kunye nokuxabiseka kobomi kunye nefilosofi yethu yeshishini kukusebenza nabathengi bethu ukukhathalela impilo yabantu ngenkonzo ekhethekileyo, umgangatho ophezulu kunye nexabiso eliphezulu.
Wamkelekile ukuba Joyina amakhulu abathengi bakaXinnuo abonwabileyo ukuvelisa iimveliso ezisemgangathweni zeTitanium kubomi obusempilweni bomntu kunye nobomi obonwabisayo.
