Akunjalo nje ngamacwecwe aphezulu, kodwa iiproproproheses ezisetyenziselwa ukulungisa umbala kunye nombala wokumomotheka. Ukugubungela okufakelwayo kubandakanya kuphela umgangatho wangaphambili kunye nomgca wezinyo.
Ziziphi iintlobo ezikhoyo?
Kukho iintlobo ezi-2 ze-microprosthesis kumbuzo, udidi lusekwe kwizinto zokuvelisa. Iintlobo zeziqhamo:
- udidi;
- ikheramic.
Ngethuba lokukhethwa kwezixhobo zokufakela, udokotela wamazinyo kufuneka achaze ngokucacileyo ukuba yiziphi izinto ezibonakalayo, izikhanyisi kunye ne-ultras, kwaye ziphi iimeko ezingafaniyo. Iintlobo zokugqibela ze-micro-prostheses zibiza kakhulu kunezinto ezincinci. Zenziwe kwaye ziqhotyoshelweyo zisebenzisa iteknoloji efanayo, kodwa ukusetyenziswa kwabo akufuneki umonakalo oqingqileyo kwiiyoti zinozinyo zemvelo.
Veneers Composite
Ezi zixhobo ziyenziwe nge-resin ephilayo kunye ne-glass okanye i-microparticles ye-ceramic.

Ugqirha ubanika ukubonakala kokugqibela emlonyeni, emva kokuxubha umgca obuncinci be-enamel. Olu hlobo lwezityalo luyacetyiswa ukuba lufakwe ukuphucula amazinyo angama-1-2 ngokulandelanayo, kuba iya kuphela iminyaka emi-3-5.
Ukuba ufuna iindawo ezinamafutha angaphambili kwizinyathelo zangaphambili, okanye ekulungiseni kufuneka udinga ummiselo onomothekayo, kufuneka ukhethe indlela yebhubhoratri yokuvelisa iiplate. Kule meko, umhlathi uyasuswa emlonyeni wokuqala, ngokuhambelana noluphi uchwephetha owenza umzekelo. Ngenxa yeskimu efunyenweyo, i-veneers zenziwe, zipholiweyo kwisithando esithile esikhethekileyo, esiqinisekisa ubomi obunexesha elide kunye namandla ongcwecwe.

- Classic. IiVeners zenziwe ngokugqitywa kwepowam powder, efuna ukunyanziswa kwe-polymerization.
- Ukucindezela. Iidrafta zibunjwa phantsi kwengcinezelo ephezulu.
- Ukuhlawula. Iimveliso ezincinci zinqunywe ukusuka kwibloko eyodwa yezinto zeramic.
Iziphumo eziphambili zifakwe ngepeyinti ezikhethekileyo, eziqinisekisa ukuba umbala wazo uhambelana neentambo ezinamazinyo ezimileyo. Ukongezelela, i-dentist-technician ibuyela kwii-ceramics iimpawu ezizodwa ze-koqweqwe lwendalo. Ezi zizona zinto zihamba phambili ngaphambi kokuba emva kwezithombe zibonise ukuba ezi zixhobo zikhangeleka ngokwemvelo kwaye ngexesha elifanayo zibonelela ngokulungiswa ngokuthe ngqo kweso dazinyo. Zihlala zihlala (ubuninzi malunga neminyaka eyi-10-15) kwaye zinamandla, ngokungafani namacroprostheses amaninzi, ayitshintshe umbala wangaphambili.
Hollywood Laminates
Iyona ndlela iphezulu kakhulu, ikhuselekile kwaye ihlala iindawo zaseMelika ezincinci ezingenawo amazinyo. I-teknoloji yokwenza kwabo yayinelungelo lobunikazi yi-Cerinate yenkampani phantsi kwe-brand Lumineers. Amacwecwe achazwe akwenziwa kuphela eCalifornia ngomyalelo ngamnye. Zibukeka zendalo ngaphezu kweenkontila ze-ceramic, kuba ziphantse zibala.
Iimvumi ezidumileyo kunye nabalingisi baseHollywood zikhetha izikhanyisi-ngaphandle kokuguqula amazinyo ezendalo ze-enamel zihlala zingenakonakaliswa, ezinjalo iinkqubo ezincinci zingatshintshwa okanye zisuswe ngaphandle kwemiphumo. Ezi zinxibo zinzima kakhulu, ubomi babo benkonzo budlula iminyaka engama-20. Okukuphela kwezinto - ngenxa yokukhanya kwezinto ezikhanyisayo akukhuthazwa ukuba zisetyenziswe phambi koqweqwe olubonakalayo kunye nebala elibonakalayo.
Enye indlela eya kuthethwa ngayo i-linings ibonwa yi-ultraniry. Ziyi-Russian analogue yamaLumineers, eyenziwe ngezinto ze-camiyam zamandulo ze-IPS E. MAX. I-Ultrasonics ixabiso elincinci kunezixhobo ezincinci ze-Californian kwaye zidalwe ngokukhawuleza, kodwa ukuphila kwabo okuqinisekileyo kuncinci kwiminyaka eyi-10-15, kwaye kwezinye iimeko kukho imfuneko yokugaya amazinyo akho ukufakela.
