Ochwepheshe emkhakheni wezakhi zofuzo emashumini amaningi eminyaka babesetshenziselwa izinto eziphumelela kakhulu ezizoba namandla okudinga futhi zizophephile kubantu. Imiqhele ye- Zirconium yinto entsha, etholakala ku-zirconium dioxide, esungulwe kahle futhi ivumela ukufakwa kwezidakamizwa kwanoma yisiphi isisindo.
I-Zirconia imiqhele yamazinyo
Uma kuqhathaniswa nezinye izinto ezivamile, i-zirconium ingabizwa ngokumane nje. Ngesizo salo, ungafinyelela umthunzi onembile kakhulu womklamo, oseduze kakhulu nombala wamazinyo emvelo. Bajwayele ukujwayele futhi bakhonze isikhathi eside, ngaphandle kokubangela ukungakhululeki.
Ngaphezu kwalokho, kufanele kuqashelwe izinzuzo ezinjalo zemikhosi ye-zirconium.
Ukuzivumelanisa okuphelele kwe-prosthesis, ngenxa yokuthi leyo nto ayifani kahle, ngaphandle kokubangela ukungezwani komzimba.
Izakhiwo eziphezulu zamandla, okuvumela ukufaka umqhele we-zirconium ekufakweni noma ekutsheni izinyo.
Ubuchwepheshe be-Laser ikuvumela ukuba wenze umqhele wobuncane obunembile ngokuqondile, ngakho-ke akudingeki ukuba uhlaziye izinyo, okuthinta kahle isimo sayo esikhathini esizayo.
Sekuyisikhathi eside, umqhele ugcine izindawo zayo zokusebenza nokuhleleka.
I-Zirconia imiqhele emazinyo angaphambili
Isimo esibalulekile sama-prosthetics amazinyo angaphambili ukusetshenziswa kwemikhiqizo ephakeme kakhulu futhi ehlala njalo.
Ama-prostheses afakwe esikhundleni samazinyo abonakalisiwe noma abonakalayo noma, uma engekho emiphakathini. Ngokusobala kwayo, i-zirconia isondelene kakhulu nezinyosi zamazinyo. Udokotela ukhetha umthunzi ngamunye kumthengi ngamunye. Ngenxa yokuqina okuphezulu kanye nobude bokusebenza, akufanele ukhathazeke ngokuthi ngokuhamba kwesikhathi imiklamo izosulwa noma iguquke.
Zirconium imiqhele yamazinyo okuhlafuna
Ubukhulu bezinzuzo ze-zirconium dioxide bavunyelwe ukuyisebenzisa ukuze kutholakale amazinyo okuhlafuna. Ngenxa yokuzibophezela okuqinile kwezakhiwo kuya ku-gomini, amathuba okubhujiswa akhishwe futhi ukuvinjelwa kokudla kuvinjelwe. Lokhu kunciphisa ingozi ye-caries.
Okunye okumele kuqaphele ukuntuleka kwesidingo sokususa i-nerve, futhi isinyathelo sokuzivikela esiyovimba kuyokwenqabela ukwakheka kwamazinyo eduze kwama-prosthesis.
Umqhele we-Metal-ceramic noma i-zirconium?
Ukungalungi okuyinhloko kwe-zirconia yizindleko zayo eziphezulu. Yilokho okubangela iziguli eziningi ukuba zithande izinto eziwusizo ezishisayo.
I-ceramics ye-metal ifana nomthunzi wemvelo, kodwa ayinakho ukukhanya kwemvelo.
Imiqhele yamazinyo e-Zirconia ayi-hypoallergenic, ngokungafani nensimbi. Ngokuzibandakanya kwayo, okuqukethwe akuphansi ngisho negolide.
Ngenxa yobukhulu obuncane be-zirconium prostheses, akudingekile ukuqina, okungeyona indaba nge-cermet enamandla.
Kancane kancane, izakhiwo ze-cermet ziphenduka okwesibhakabhaka nxazonke zomphetho, okubonakala ngokuphawulekayo lapho umuntu ehleka.
Ukukhiqizwa kwekhompyutha kanye nenqubo yokuzenzakalela kwenza kube lula ukugwema noma yimaphi amaphutha futhi ufeze ukunemba okuphezulu. Lokhu kuqinisekisa ukunamathela okunembile nokuvimbela ukuvuvukala, okungeke kutholakale ngesikhathi kukhishwa ibhulogi yamacermet.
Ukuphila kwensizakalo yemikhosi ye-zirconium iminyaka engu-15, kuyilapho begcina ngokugcwele ukubukeka kwabo kwasekuqaleni. Imikhiqizo ye-Ceramic isebenza isilinganiso seminyaka eyi-10.
Ukuqhubekela phambili ngenhla, kungaphawulwa ukuthi izinga eliphezulu nokuqina kuhlanganisa ngokugcwele izindleko ze-prostheses. Ngakho-ke, odokotela batusa ukusebenzisa i-zirconium.
