Ukubukeka emphakathini wanamuhla kunikelwa ukunakwa okukhulu. Akuyona incazelo yokugcina enikezwe ukumomotheka. Yenza umbono wokuqala womuntu futhi umnike umqondo wokuzethemba. Nokho, akuwona wonke umuntu ongabaziqhenya ngokumomotheka kwe-Hollywood. Ukulungisa isimo esifanayo kuzosiza izitsha ze-ceramic. Imithi yanamuhla iyakwazi ukudala izimangaliso zangempela.
Iyini i-ceramic veneer kumazinyo omzimba?
Lawa angama-microprostheses afana namacwecwe amancane. Zisetshenziselwa ukunikeza amazinyo isimo nesimo esithile. Ngenxa yokuthi ubuchwepheshe obusha busetshenziselwa ukukhiqiza ama-microprostheses, lawa macwecwe abukeka engokwemvelo. I-prosthetics enezicathulo ze-ceramic - lokhu okunye okunye okunamandla kuya emakhanda anomphumela we-esesthetic we-incisors.
Inqubo enjalo inconywa ukuba yenziwe kumacala alandelayo:
- Umbala wezinyo zama koqweqwe lwawo ushintshile. Ngenxa yokusetshenziswa kwezidakamizwa ezithile, i-incisors ingavezwa e-pink or red hue. Ngaphezu kwalokho, umbala wamazinyo ushintsha ngokuqukethwe okuphezulu kwe-fluoride emanzini.
- Ububanzi obukhulu kakhulu phakathi kwama-incisors. I-microprosthesis efanayo isiza ukulinganisa ukuphakama kwamazinyo.
Zinezicathulo ze-ceramic nezinkampani zokuphikisana okufanele zisetshenziswe. Lokhu kufaka lokhu okulandelayo:
- ukubhujiswa okuphazamisayo;
- iphutha elingalungile ;
- i-tooth fluoridation;
- ukutholakala kwemikhuba emibi (ukuqoqa izipikili, izintambo zokugcoba njalonjalo);
- inqubo yokuvuvukala emgodini womlomo;
- ukuchithwa okuqinile kwama-"tissue" wamazinyo.
Uyini umehluko phakathi kwama-veneers nama-ceramic veneers?
Lezi microprosthetics zihluke kakhulu kusuka komunye nomunye. Izingqungquthela zibhekwa ngokuthi "ziqondile". Bafakwe ekuvakasheni okunye kudokotela. Inqubo yokubuyiselwa kwamazinyo iqukethe uhlelo lokusebenza oluzingqayizivele lwezingqimba zenhlanganisela ebusweni. Ngenxa yalokho, i-microprosthesis ixhunywe ngokuqinile kwi "tissue" futhi inqola ayinakwenzeka. Lezinto ezibonakalayo zikhishwa nge-koqweqwe lwawo, ngakho-ke ama-veneers ahluke ngokuphelele kwamanye amazinyo.
I-Ceramic micro-prostheses (ebizwa nangokuthi i-porcelain) yenziwa ematokolini akhethekile, kucatshangelwa izilinganiso ezenziwe ngaphambili zesiguli. Uqedile amacwecwe okuhlobisa ahlelwe phezu kwamazinyo abuyiselwe ngosizo lwe "glue" ekhethekile. Uma ukhetha izingqimba ze-composite noma ze-ceramic, isiguli kufanele sibuze udokotela ngokuningiliziwe mayelana nezinzuzo nezinsalela zalezi microprostheses. Ngemuva kokuhlaziya ulwazi olutholiwe nokulalela izincomo zedokotela wamazinyo, kuyoba lula ngaye ukwenza isinqumo esihle kakhulu.
Amakhemikhali amakhemikhali kanye ne-ceramic - okungcono?
Ukuhlola okuhloswe kwezici eziqhathaniswayo ezincane ezincane kuzosiza ekuhlunguleni lo mbuzo. Kusukela ekufikeni kwama-veneers ahlanganisiwe asetshenziswe njengendlela ehlukile kumacwecwe e-ceramic. Noma kunjalo, ezincane ezincane zingabonakala zifihla amaphutha amancane kuphela. Zingasetshenziswa ngezizathu ezilandelayo:
- shintsha ngokuma kwezinyo zangaphambili ngenxa yokulimala noma ukulimala okuncane;
- ukungahambisani okungafaniyo kwentamo yethuluzi;
- ukuguqulwa kwe-koqweqwe lwawo koqweqwe lwawo, olungalokothi lubole ekusikeni;
- ukunyamaza ngokuhamba kwesikhathi ukugcwalisa impahla.
Kodwa-ke, ukubuyiselwa kuphela nge-ceramic veneers kuzosiza ukufihla ukukhubazeka okulandelayo:
- ukugcoba okukhulu noma i- hypoplasia ye-koqweqwe lwawo ;
- ukwedlula ukwanda kwama-incisors okubangelwa ubhujane noma ezinye izifo;
- i-bite yokulimaza.
I-Veneers - inzuzo neqholo
"I-microprosthetics" eqondile inezici ezinjalo ezinhle:
- ukonga isikhathi sesiguli (ukufakwa kwamacwecwe okuhlobisa kwenziwa ngokuvakashelwa oku-1 kudokotela wamazinyo);
- izindleko zokubuyiselwa zithengeka kakhulu kunezicucu ze-ceramic;
- Abaqashi bahlelwa kancane ngaphambi kokuhlobisa.
Lolu hlobo lwe-microprosthesis lunezinkinga zalo. Okubaluleke kakhulu yilezi zinhlobo ezilandelayo:
- Ngokuhamba kwesikhathi, bangashintsha ngombala;
- banamandla aphansi uma kuqhathaniswa nama-ceramic;
- impilo yesikhashana (kusukela eminyakeni emi-3 kuya kwengu-7);
- baphenduke ngotshwala (babhujiswa ngaphansi kwethonya lokuphuza utshwala kanye nama-rinsers, aqukethe i-ethanol).
I-Ceramic veneers inezinzuzo ezilandelayo:
- amandla nokuhlala;
- ukumelana nemibala ehlukahlukene yokudla, ngakho-ke akukho ama-stain surface kanye ne-plaque evele;
- kusiza ukuvuselela isakhiwo sezinyo, esibuyiselwe.
Ukungahleleki kwe-ceramic veneers kuncane kakhulu kunokuba kuhlanganiswe "microprostheses" eqondile. Okubaluleke kunazo zonke kulezi izindleko eziphezulu zokubuyiselwa. Ngaphezu kwalokho, ukungalungi yiqiniso lokuthi ukufakwa kwamapuleti okuhlobisa akunakwenziwa ngesikhathi. Ekuvakasheni kokuqala, udokotela wamazinyo ulungisa amazinyo futhi enze umqondo, futhi i-veneer yesikhashana ifakwe ebusweni be-incisor. Lapho udokotela ehambela udokotela futhi, i-microprosthesis efakiwe isusiwe, futhi ukuhlobisa okuhlala njalo kulungisiwe endaweni yayo.
Ukufakwa kwama-ceramic veneers
Inqubo yonke ye-microprosthesis ingahle ihlukaniswe ngokomzimba zibe izigaba eziningana:
- Imitholampilo. Udokotela wamazinyo uqhuba izinqubo zokuxilonga (uhlola isigxobo somlomo) futhi ukhetha ithoni yamaphrofayli amancane. Lezinyo ngokwayo inezindawo ezintathu ezihlukene: indawo ye-basal, eyisisekelo nokusika. Ngamunye wabo unomthunzi wawo, ngakho umsebenzi wezinyosi wamazinyo ukuthola ukhetho jikelele.
- I-Laboratory. Ngokwenziwe ama-prints amapulangwe okuhlobisa. Lokhu kwenza ubuchwepheshe bama-ceramic veneers asondelene namazinyo emvelo kanye nekhwalithi eliphezulu.
- Imitholampilo. Kulesi sigaba, i-microprosthesis ivivinywa kuqala bese ifakwa.
Ukuguquka kwezinyo ngaphansi kwe-ceramic veneer
Le nqubo yenziwa ngokufakwa kwemikhakhaza eqondile neqondile. Nikeza ukulungiswa kwe-ceramic veneers, emele izigaba ezilandelayo:
- Isicelo esingaphansi kwemigqa eguquguqukayo.
- Ukutshontsha cishe izinhlangothi.
- Ukwenza umkhawulo wokusika. Kulesi sigaba, ukugaya kwenziwa ngokujula kwe-1-2 mm.
- Ukwelashwa kwesifunda se-palatal.
- Ukuqeda ukugxuma, okususa yonke imiphetho ebukhali.
Ukulungiswa kwama-ceramic veneers
Ngemva kokuguqula amazinyo, udokotela uyaqhubeka nokulungisa ama-microprostheses. Ukulungiswa kwama-veneers okwamanje kuthinta amasayithi amathathu:
- indwangu enzima yokusika;
- i-plate ceramic;
- "Glue".
Lezi zindawo zihlukile komunye nomunye ekwakhiweni kwamakhemikhali, ngakho-ke, ukuze kube nokulungiswa okuqinile, ukwelashwa okukhethekile kwalowo nalowo kuyadingeka. I-veneer ifakwe kanje:
- I-plate yokuhlobisa ihlanganiswe ne-hydrofluoric acid. Ngenxa yalokhu kusebenza, ama-pores avela ebusweni be-microprosthesis, okuyinto esikhathini esizayo ezohlinzeka ukuxhuma okuhle.
- Izinyo ezibuyiselwayo ziphathwa nge-component abrasive.
- I-asidi ekhethekile isetshenziswa ebusweni bomunqamu imizuzwana engu-15.
- Lezinyo zimbozwe nge-primer futhi zomisiwe. Khona-ke isetshenziswa "iglue".
- Ingxenyeni yangemuva yeplati yokuhlobisa ihlanganiswe ne-fixer, futhi i-veneer ifakwe ezinyoweni ezibuyiselwe. Isikhulumi "glue" sisusiwe.
- Ukugaya nokwenziwa kwepolymerization kwenziwa.
I-Ceramic veneers - impilo yesevisi
Isikhathi sokusebenza samapuleti anjengokuhlobisa sikhulu kunamacroprostheses ahlanganisiwe . Ukuphila komsebenzi we-ceramic veneers kungaphezu kweminyaka engama-20. Kodwa-ke, kuphela lezo ziguli ezihambisana neziphakamiso ezilandelayo zingalindela lokhu:
- kabili ngonyaka uvakashele udokotela wamazinyo;
- qaphela ukuhlanzeka komuntu siqu;
- ukuvikela amazinyo emandleni (ungadli amantongomane, ungavuli ibhodlela).
Kungenzeka yini ukulungisa izivali ze-ceramic ezinikeziwe kakade?
Udokotela angenza ukuphenduka okuyingxenye yalezi zingqimba zokuhlobisa, kodwa sikhuluma ngezilungiso ezincane. Zonke izilungiso kufanele zenziwe ngaphambi kokufakwa (esigabeni esifanele). Kuncike ekutheni udokotela wamazinyo kuyi-jeweler yangempela, asikho isidingo sokulungiswa okuqhubekayo ngemva kokufakwa. Lokhu kuboniswa ngokucacile yi-veneers ceramic - izithombe ngaphambi nangemva.
