Izakhi zofuzo, ukuhlanzeka kanye nezimo zezemvelo yizici eziqakathekileko esimweni somuntu we-dentoalveolar system. Abantu abanamazinyo aphelele emvelo ngokwemvelo abavamile kakhulu, iningi labo kufanele liye kudokotela wamazinyo ngokuvamile ngenxa yokubhujiswa nokulahlekelwa kwamazinyo. Lokhu kuholela eqinisweni lokuthi inani elikhulu labantu libhekene nombuzo wokuthi yiziphi izinhlobo zomqhele wamazinyo, ngoba umsebenzi wokuhlafuna ophansi oholela ezinkingeni nasezifo ezihlukahlukene zomzimba.
Yini imiqhele yamazinyo?
Amacala lapho kusetshenziswe umqhele kuhlanganisa:
- ukubola kwezinyo okuyingxenye ngenxa yezinhlayiya kanye nezinkinga zayo, lapho ukubuyiselwa ngezinto ze-photopolymer akunakwenzeka noma kungenangqondo;
- ukubhujiswa okuphelele komqhele wezinyo ngezinsizi ezisele (usebenzisa umqhele wamazinyo ku-pin);
- lapho kuphazamiseka kwamazinyo;
- njengengxenye ebalulekile yebhuloho;
- njengesigaba sokugcina samazinyo;
- ukuqeda ukukhubazeka kwamazinyo amazinyo.
Izinhlobo zemikhosi yamazinyo
Amazinyo wamanje ahlukanisa imiqhele ngokuyinhloko kwento yokwenza. Izinhlobo ezisetshenziselwa umqhele wama-prosthetics yamazinyo ngokuvamile:
- Imiqhele yeminyo yensimbi. Lena enye yezinhlobo zakudala ezingavamile ukusetshenziswa emitholampilo yanamuhla. Isizathu siwukuthi imiqhele ayinamaqiniso kakhulu, ikakhulukazi emazinyo angaphambili. Yize izinzuzo zabo zingamanani aphansi, kanye nokumelana nokuhlafuna nokugqwala. Izitshalo ezisemqoka, ezinamakhomikhali anjalo ayenziwa, ziyi-nickel, i-chrome, i-cobalt, igolide.
- Imiqhele yamazinyo eyenziwe ngeplastiki yensimbi kanye nepulasitiki sekuyisikhathi eside isetshenziselwa ukuhlala nge-prosthetics. Ezinyokwelapha zesimanje, imiqhele enjalo isetshenziswa kuphela njengesikhashana. Phela, ukuqina kwabo akungabazeki. Imiqhele yePlastiki elula isula ngokushesha, ngenxa ye-fragility yendaba. Ngaphezu kwalokho, badonswe ngamakhoyi ekudleni futhi baqoqa ngokwabo inani elikhulu lama-bacteria, okuholela ekubukeni kwendumalo engavamile emlonyeni . Imiqhele ye-Metal-plastiki nayo ihlala isikhathi esifushane, ngoba ukuhlanganiswa kwensimbi nesipulasitiki akunamandla futhi iplastiki igcina ifinyelela.
Izinhlobo zanamuhla zemikhosi yamazinyo
Amakhanda ensimbi yama-ceramic
Eminyakeni embalwa eyedlule le miqhele yabhekwa njengesiqhwaga, manje seyiye yawela cishe esiteji esincane kunazo zonke eminothweni yamazinyo. Inzuzo yabo iyinani eliphansi uma kuqhathaniswa namanye amakhanda anamuhla, kanye nezimfanelo ezinhle zokuhleleka kwamazinyo kanye namandla. Isisekelo somqhele yi-alloy yensimbi, phezu kwayo inqwaba ye-ceramic.
Amakhanda Amazinyo Aphelele-Ceramic
Embuzweni wokuthi imikhosi yamazinyo ingcono kakhulu, cishe wonke amazinyo omuthi wesimanje uzophendula ukuthi yonke i-ceramic. Ngemva kwakho konke, wabo
Okungokwesimanje kakhulu futhi okuphethe izimfanelo ezinhle kakhulu ngokwezindlela zobuchwepheshe be-aesthetics namandla abiza imiqhele ye-ceramic ngokusekelwe ku-zirconium. Lokhu okubonakalayo okubonakalayo kunomphumela owodwa kuphela - inani eliphezulu. Lokhu kungenxa yobuchwepheshe bokukhiqiza - le miqhele ikhiqizwa kumishini ekhethekile yokugaya elawulwa ubuchwepheshe bekhompuyutha, eqinisekisa impilo yesikhathi eside kanye nezimfanelo zobuhle ezingacabangi.
