Ngaphambili, ii-prostheses zamazinyo zazingabonwa ngokucacileyo ekuqaleni kokubona, ekubeni zenziwe ngezinto ezahluke kakhulu kubonakala kwi-koqweqwe langempela. Esikhundleni sazo safika nge-ceramics ezingezantsi zetsimbi - ingqungquthela ehamba phambili kunye neyenamhlanje ye-prosthetics, enika amandla amaninzi kunye nama-aesthetics amakhulu.
Yintoni ekusetyenziswa ngayo iiceramics zensimbi ezingenanto?
Ukongeza kwimizimba yesithsaba kunye nezithsaba, izinto ezichazweyo zisetyenziselwa ukuveliswa kweemveliso, izikhanyisi kunye nezifakela (ukufaka iifom). Ngoncedo lwaso, ukubuyiswa kwamazinyo kwenziwa, emva koko kubonakala kuyindalo.
Njengomthetho, i-ceramic engekho yensimbi efakwe kwizinyo zangaphambili, njengoko ivumela ukufezekisa ukubonakala okulungileyo kunye nobuhle. Ukongezelela, izinto ezibhekiselwe kumbuzo azifanelekanga kwimimandla ngenxa yokuba ngexesha lokutshiza, bafumana umthwalo ophezulu, onokukwazi ukulimaza amazinyo e-ceramic, izithsaba okanye iintambo.
Iindidi ze-ceramic ezingekho zetsimbi
Namhlanje ukulawa kwamazinyo kukho iintlobo ezi-3 zezi zinto:
- Ukugonywa ngeekeramiki (ngokupheleleyo, iglasi-ceramics). Olu hlobo lwento eluhlaza lubonakaliswe kwisakhiwo esicatshungulwayo esingaqhelekanga singabonakaliyo kwi-tooth ejensi yemvelo.
- Ngokusekelwe kwi-aluminium oxide. Izinto eziveziweyo, ngaphandle kweendlela eziphezulu zokubonisa izixhobo, zihlala zizinzile. Ngoko ke, kunokwenzeka ukwenza iincorisi ezingaqhelekanga kuphela, kodwa kunye namabhanti, ukusuka kwii-ceramics kwifom ye-alumina.
- Ngokusekelwe kwi-zirconium oxide. Ngokubhekiselele kwiimpawu zolu hlobo lweeramics zidlula i-analogue esekelwe kwi-aluminium oxide. I-Zirconium prostheses yi-hypoallergenic, ayichaphazeli izitho zangaphakathi, iinsini, amazinyo. Ukongeza, ii-ceramics ezinjalo zihlala zizinzileyo kwaye, ngoko ke, zihlala zihlala.
Iinjongo zeekeramiki ezingezantsi zetsimbi
Xa kuthelekiswa "nabathengisi" bayo ngqo, i-photopolymer kunye nezakhiwo zensimbi zeramic, izinto ezichaziweyo zinamathuba alandelayo:
- ukhanyiso lwendalo engaphezulu kwamazinyo abuyiselwe;
- ukufana okupheleleyo kweentlobo ze-prostheses kunye ne-linings kunye ne-eamel eyoqobo;
- ukugqithisa ngakumbi, ukuphindaphinda amazinyo akho, ukuma;
- ukulondolozwa kwempilo kunye nokubonakala kwegum kufuphi;
- ukungabikho kweenkqubo ezivuthayo kwiisiski ezinqamlekileyo ezungezile;
- u-hypoallergenicity, ukukhutshwa kwengozi yokucaphukisa nokuphuma kwegazi;
- Ukunciphisa, akudingeki ukuba ugaye indawo enkulu yamazinyo;
- ukuguquka kwendalo kunye nokubonakala kakuhle;
- Umbala ozinzile, ungatshintshi iminyaka eyi-10-15;
- ubuninzi bobunzima bokubambelela kwizinto ezinokubambezeleka ngaphandle kokulimaza;
- ukunakekelwa okuzimeleyo ngokukhawuleza;
- isidingo esinqabileyo sesevisi.
Zithini izithsaba ezenziwe ngeekeramiki ezingezantsi zetsimbi?
Ukuveliswa kwanoma yiyiphi inketho yeprothesis iqala ngokususwa kwempembelelo kwimihlathi. Kulo luhlobo oluthile lwezithsaba ezizayo, amabhuloho okanye ukugqithisa ngokuhambelana neemfuno
Ngesiseko somzekelo we-wax, uhlobo olukhethiweyo lweeramics luxinzezelwe. Ukuba kuyimfuneko, ii-prostheses ezifunyenwe zilungisiwe kwaye zicutshungulwa ngezixhobo zedayimani echanekileyo, ukwenzela ukuba izithsaba ziphephe kakuhle kwaye zisondele kunokwenzeka kwi-gum.
Kwixesha elizayo, ukubuyiselwa kwamazinyo kuqhutywa ngutitshala. Ukufakela ngokugqithisileyo iifrefesi kufakwe lula, ngokukhawuleza kwaye kungenabuhlungu, ubuncinci bokuvakalelwa kwesigulane.
