I-Titanium ibe lolona khetho lokuqala kwii-implants zotyando kwicandelo lezonyango ngenxa yeempawu zayo ezintle kunye nokuhambelana kwayo nezinto eziphilayo. Kwiminyaka yakutshanje, ukusetyenziswa kwe-titanium kwii-implants zamathambo namazinyo, kunye nezixhobo ezahlukeneyo zonyango, kuye kwanda kakhulu. Oku kunyuka kokuthandwa kunokubangelwa ziimpawu ezikhethekileyo ze-titanium ezifana namandla, ukumelana nokugqwala kunye nokuhambelana nomzimba womntu. Kweli nqaku, siza kuhlola izizathu zokuba kutheni i-titanium ibe yinto ekhethwayo kwii-implants zonyango, kunye nemigangatho ethile kunye namanqanaba aqinisekisa ukufaneleka kwe-titanium kwiindlela ezinjalo.
Esinye sezizathu eziphambili zokusetyenziswa kakhulu kwe-titanium kwii-implants zonyango kukuhambelana kwayo ne-biocompatibility. Xa into ithathwa njengehambelana ne-bio, oko kuthetha ukuba inyamezelwa kakuhle ngumzimba kwaye ayibangeli iziphumo ezibi zokuzikhusela komzimba. Ukuhambelana kwe-Titanium ne-biocompatibility kungenxa yokukwazi kwayo ukwenza umaleko omncinci wokukhusela i-oxide kumphezulu wayo xa ivezwe kwi-oksijini. Olu maleko we-oxide lwenza i-titanium ingangeni kwaye imelane nokugqwala, okuqinisekisa ukuba ayizukusabela kulwelo lomzimba okanye kwizicubu. Ngenxa yoko, ii-implants ze-titanium azinakwenzeka ukuba zibangele ukudumba okanye ukwaliwa, nto leyo eyenza ukuba zibe lukhetho olukhuselekileyo nolunokuthenjwa kwiisicelo zonyango.
Ukongeza kwi-biocompatibility, i-titanium inomlinganiselo ogqwesileyo wamandla nobunzima, nto leyo ibalulekileyo kwi-implants ekufuneka imelane noxinzelelo loomatshini kunye noxinzelelo lomzimba. Nokuba zezokufakelwa ngotyando, izixhobo zokulungisa amathambo okanye ii-implants zamazinyo, izixhobo ezisetyenziswayo kufuneka zomelele ngokwaneleyo ukuxhasa imisebenzi yomzimba ngaphandle kokuba zinkulu kakhulu. Amandla aphezulu e-Titanium kunye noxinano oluphantsi kuyenza ibe yinto efanelekileyo yokusetyenziswa kwezi zinto, inika inkxaso yesakhiwo esifunekayo ngaphandle kokongeza ubunzima okanye uxinzelelo olungafunekiyo emzimbeni.
Ukongeza, i-titanium inokumelana okuhle nokugqwala, nto leyo ibalulekileyo kwi-implants ezihlala emzimbeni ixesha elide. Indawo engqongileyo yomzimba igqwala kakhulu, kwaye ulwelo oluninzi lomzimba kunye nee-electrolytes zinokubangela ukuba i-implants zesinyithi ziwohloke ngokuhamba kwexesha. Umaleko we-oxide yendalo we-Titanium usebenza njengomqobo wokugqwala, oqinisekisa ukuzinza kwexesha elide kunye nokuthembeka kwe-implant emzimbeni. Olu kumelana nokugqwala kubaluleke kakhulu kwi-implants kwizicelo zokuthwala umthwalo, ezifana nokutshintshwa kwe-hip kunye nedolo, apho izinto kufuneka zimelane noxinzelelo oluqhubekayo loomatshini ngaphandle kokuwohloka.
Imibutho emininzi yamazwe ngamazwe ineemfuno ezingqongqo zemigangatho ethile kunye neendidi ze-titanium ezisetyenziswa kwi-implants zonyango ukuqinisekisa umgangatho kunye nokhuseleko lwale mpahla. I-American Society for Testing and Materials (ASTM) iphuhlise imigangatho efana ne-ASTM F136 kunye ne-ASTM F67 echaza ukwakheka kweekhemikhali, iimpawu zoomatshini, kunye neendlela zokuvavanya i-titanium yenqanaba lezonyango. Le migangatho iqinisekisa ukuba i-titanium esetyenziswa kwi-implants ihlangabezana nemigangatho efunekayo yokuhambelana kwezinto eziphilayo, amandla, kunye nokumelana nokugqwala.
Ukongeza, i-International Organisation for Standardization (ISO) ichaza amanqanaba athile e-titanium, njenge-ISO 5832-2, ISO 5832-3, kunye ne-ISO 5832-11, ezisetyenziswa kakhulu kwi-orthopedic and dental implants. Le migangatho ye-ISO ichaza iimfuno ze-titanium alloys ezisetyenziswa kwi-inplants zotyando, kubandakanya ukwakheka, iimpawu zoomatshini, kunye novavanyo lwe-biocompatibility. I-Ti6Al7Nb yi-titanium alloy eyaziwayo kwi-implants zonyango, edibanisa amandla aphezulu, i-biocompatibility kunye ne-corrosion resistance kwiindidi ezahlukeneyo zezixhobo ezifakelwayo.
I-Titanium yokufakelwa kwezonyango idla ngokufumaneka ngohlobo lweentonga, iingcingo, amashiti kunye neepleyiti. Ezi ntlobo zahlukeneyo zingasetyenziselwa ukwenza iintlobo ezahlukeneyo zokufakelwa kunye nezixhobo, ukusuka kwizikrufu zamathambo kunye neepleyiti ukuya kwizithintelo zamazinyo kunye neekheyiji zomqolo. Ukuguquguquka kwe-titanium kwiintlobo ezahlukeneyo kuvumela abavelisi ukuba balungelelanise izinto ngokweedizayini ezithile zokufakelwa kunye nokusetyenziswa kwazo, ukuqinisekisa ukuba ukufakelwa kuhlangabezana nemigangatho yokusebenza efunekayo yoomatshini kunye neyebhayoloji.
Ngamafutshane, ukuhambelana kakuhle kwezinto eziphilayo, amandla kunye nokumelana nokugqwala kwe-titanium kuyenza ibe yeyona nto ikhethwayo kwii-implants zonyango. Imigangatho ethile kunye namanqanaba afana ne-ASTM F136, ASTM F67, ISO 5832-2/3/11 kunye ne-Ti6Al7Nb aqinisekisa ukuba i-titanium esetyenziswa kwii-implants zonyango ihlangabezana neemfuno ezingqongqo zomgangatho kunye nokhuseleko. Ngenxa yokukwazi kwayo ukumelana nokusingqongileyo komzimba kunye nokubonelela ngozinzo lwexesha elide, i-titanium iyaqhubeka nokudlala indima ebalulekileyo ekuphuculeni itekhnoloji ye-implants zonyango kunye nokubonelela izigulane ngezisombululo ezinokuthenjwa nezihlala ixesha elide kwiimfuno ezahlukeneyo zamathambo kunye namazinyo.
Sikhokelwa liqela leenjineli ezikrelekrele kunye neengcali zoshishino ezinamava obuchwephesha angaphezu kweminyaka engama-20 ekwenzeni izinto ze-titanium ezikumgangatho ophezulu. Siyaqonda ukuba ubomi buhlukile kwaye buxabiseke kangakanani kwaye ifilosofi yethu yeshishini kukusebenza nabathengi bethu ukunyamekela impilo yabantu ngenkonzo egqwesileyo, umgangatho ophezulu kunye nexabiso eliphezulu.
Wamkelekile ukuba ujoyine amakhulu abathengi abonwabileyo baseXinnuo ukuze uvelise iimveliso zeTitanium ezisemgangathweni ukuze umntu abe nobomi obusempilweni nobonwabisayo.
