Ngaphambili, ama-prostheses yamazinyo angabonakala ngokucacile ekuqaleni kokubona, ngoba ayenziwe ngezinto ezahluke kakhulu ezivela koqweqwe lwawo lwangempela. Esikhundleni sazo zafika nge-ceramics engenazo zensimbi - inguqulo eqhubekayo kakhulu futhi yanamuhla ye-prosthetics, ehlinzeka ngamandla amakhulu kanye nama-aesthetics emangalisayo.
Iyini ukusetshenziswa kwe-ceramics engensimbi engozini yamazinyo?
Ngaphezu kwezingubo zomzimba nezinduna, izinto ezichazweyo zisetshenziselwa ukwakhiwa kwezigqoko ezikhanyayo, izikhanyisi kanye nama-inlays (ukufakelwa kokugcwalisa). Ngosizo lwaso, ukubuyiselwa kwamazinyo kwenziwa, emva kwalokho kubonakala kuyimvelo.
Njengomthetho, i-ceramic engekho yensimbi ifakwe kumazinyo angaphambili, njengoba ivumela ukufeza ukubukeka okungcono nokuhlelekile. Ngaphezu kwalokho, ukwaziswa okukhulunywe ngakho akufanelekile ukukhishwa kwemithi ngenxa yokuthi ngesikhathi sokuhlafuna, bathola umthwalo ophezulu, okwazi ukulimaza amazinyo e-ceramic, amakhanda noma ama-patches.
Izinhlobo ze-ceramics ezingensimbi
Namuhla ekulawulweni kwamazinyo akho kukhona izinhlobo ezintathu zalesi sici:
- I-ceramics egxile (konke, ingilazi-ceramics). Lolu hlobo lwezinto ezibonakalayo lubonakala ngesakhiwo esithinta umzimba esingaqondakali nhlobo esivela ekuqotheni izinyosi zemvelo.
- Ngokusekelwe e-aluminium oxide. Izinto ezinikezwe, ngaphandle kwezinkomba eziphezulu zokuhleleka, zihlala ziqinile kakhulu. Ngakho-ke, kungenzeka ukwenza amakhanda angashadile kuphela, kodwa futhi amabhuloho, kusukela ku-ceramics kuhlaka lwe-alumina.
- Ngokusekelwe ku-zirconium oxide. Ngokwezici zalolu hlobo lwe-ceramics ludlula i-analogue esekelwe ku-aluminium oxide. I-Zirconium prostheses yi-hypoallergenic, ayithinti izitho zangaphakathi, izinsini, amazinyo. Ngaphezu kwalokho, lezo zeramikhali zihlala zihlala isikhathi eside futhi, ngenxa yalokho, zihlala njalo.
Izinzuzo ze-ceramics ezingezona zensimbi
Uma kuqhathaniswa "nabathengisi" bayo ngqo, izakhiwo ze-photopolymer nezakhi zensimbi-ceramic, indaba echazwe inezinzuzo ezilandelayo:
- ukukhanya kwemvelo ebusweni bamazinyo abuyiselwe;
- ukufana okuphelele kwama-prostheses nama-linings nge koqweqwe lwawo lwangempela;
- ukukhuluma okuphelele, okuphindaphindiwe kwamazinyo, ukuma;
- ukulondolozwa kwezempilo nokubukeka kwegamu eliseduze;
- ukungabi khona kwezinqubo ezivuthayo ezithandeni ezithambile eziseduze;
- u-hypoallergenicity, ukukhishwa ingozi yokucasula nokuphuma kwegazi;
- ukugwema ukulungiselela, akudingeki ukuba ugaye indawo enkulu yamazinyo;
- translucency yemvelo nokubukeka okuhle;
- Umbala oqinile, ungashintshi iminyaka engu-10-15;
- ubukhulu obuningi bokunamathela kwento kuze kube segumini ngaphandle kokulimaza;
- ukunakekelwa okuzimele okulula nokuchitha isikhathi;
- isidingo esingavamile senkonzo yobuchwepheshe.
Kanjani umqhele okwenziwa ngamakhemikhali angensimbi?
Ukwakhiwa kwanoma yikuphi okukhethwa kukho kwe-prosthesis kuqala ngokususwa komqondo kusuka emhlathini. Kulokho okunye okumele kukhombise imiqhele yamakhansela , amabhuloho noma ukugqoka ngokuhambisana nezifiso
Ngokwemodeli ye-wax, uhlobo olukhethiwe lwe-ceramics lucindezelwa. Uma kunesidingo, ama-prostheses atholakele aqondiswa futhi asetshenziswe ngamathuluzi edayimani aphezulu, ukuze imiqhele ibukeke kahle futhi isondelene nakakhulu.
Esikhathini esizayo, ukubuyiselwa kwamazinyo kwenziwa ngumchwepheshe. Izakhi zofuzo ezifakwe kahle zifakwe kalula, ngokushesha futhi zingenabuhlungu, ezinokungabi nabuhlungu okungakalungi kwesiguli.
