Ukubonakala kwintlalo yanamhlanje kunikwa ingqalelo enkulu. Ayikho intsingiselo yokugqibela enikezwa kumomotheka. Yenza umboniso wokuqala womntu kwaye inika umqondo wokuzithemba. Nangona kunjalo, akubona wonke umntu onokuziqhayisa ngokumomotheka kwe-Hollywood. Ukulungisa imeko efanayo kuya kunceda i-ceramic veneers. Amachiza anamhlanje akwazi ukwenza imimangaliso yangempela.
Yintoni i-ceramic veneer kwiamazinyo?
Ezi zi-microprostheses ezibukeka zifana namacwecwe amancinci. Zisetyenziselwa ukunika amazinyo uhlobo oluthile kunye nombala. Ngenxa yokuba ubuchwephesha bokusetyenziswa kobugcisa basetyenziselwa inkqubo yokuvelisa i-microprostheses, ezi zicatshulwa zibonakala zendalo. Iprosthetics eneenkontileka ze-ceramic - le yindlela elula ukuya kwiisithsaba ngesiphene se-aesthetic se-incisors.
Inkqubo enjalo inconywa ukuba yenziwe kwiimeko ezilandelayo:
- Umbala wezinyosi zamazinyo ushintshile. Ngenxa yokusetyenziswa kwamachiza athile, i-incisors ingaba yenziwe ngepinki okanye i-hue ebomvu. Ukongezelela, umbala wamazinyo utshintsha ngomxholo ophezulu we-fluoride emanzini.
- Ububanzi obukhulu phakathi kwe-incisors. I-microprosthesis efanayo inceda ukuphakamisa ubude bamazinyo.
Zineemveliso zeceramic kunye neengqinisiso zokusetyenziswa. Ezi ziquka oku kulandelayo:
- ukutshabalalisa;
- ilanga elingalunganga ;
- i-fluoridation yezinyo;
- ubukho bemikhwa emibi (ukugquma izipikili, iintambo zokunqongophala kunye nokunye);
- Inkqubo yokuvuvukala emlonyeni womlomo;
- ukuqhaqhaqhaqhaqho kwamathambo "amathambo".
Uthini umahluko phakathi kweemveliso eziqingqiweyo kunye neeramic veneers?
Ezi microprosthetics zihluke kakhulu kunomnye. Iinqununu zibhekwa "ngokuchanekileyo". Zifakwe kwihambo enye kugqirha. Inkqubo yokubuyiselwa kwamazinyo iququzelelwe kwisalathisi-esecaleni kwesicelo se-composite phezu komhlaba. Ngenxa yoko, i-microprosthesis iqhotyoshelweyo ngokuthe ngqo kwi "tissue" kwaye i-detachment ayinakwenzeka. Izinto ezibonakalayo zikhupha i-eamel, ngoko ke izixhobo zihluke ngokupheleleyo kwamanye amazinyo.
I-ceramic micro-prostheses (ikwabizwa ngokuba yi-porcelain) zenziwe kwiibhubhrikhi ezizodwa, ngokuqwalasela ukulinganisa kwangaphambili kweso sigulane. Ukugqitywa kwamacwecwe okubhabisa amiselwe kwiindawo zamazinyo abuyiselwe ngoncedo lwe-"glue" ekhethekileyo. Xa ukhetha i-composite okanye i-ceramic veneers, isiguli kufuneka sicele ugqirha ngokubanzi malunga neenzuzo kunye neempembelelo zezi microprostheses. Emva kokuhlalutya ulwazi olufunyenweyo kunye nokuphulaphula iingcebiso zedokotela wamazinyo, kuya kuba lula ukuba enze isigqibo esona sigqibo.
Iimveliso eziqingqiweyo kunye neeramic - into engcono?
Uvavanyo lweenjongo zokuthelekisa iimpawu ezinjalo ezincinci ziza kunceda ukulungisa lo mbuzo. Ukususela ekufikeni kweemveliso eziqingqiweyo baye basebenziswa njengenye iiplani zeekeramic. Nangona kunjalo, ezinjalo iiproproprosthes ziyakubonakala zifihlile iziphene ezincinane. Zingasetyenziselwa izizathu ezilandelayo:
- utshintshe ngohlobo lwezinyo langaphambili ngenxa yempembelelo okanye ukulimala okuncane;
- intambo engalinganiyo entanyeni yesixhobo;
- i-pigmentation ye-enamel, engayithengi ukuba i-bleaching;
- kubumnyama emva kwexesha ukuzalisa izinto.
Nangona kunjalo, ukubuyiselwa kuphela ngeenkontileka ze-ceramic kuya kunceda ukufihla ezi mpazamo zilandelayo:
- ukucuthisa okunzima okanye i- hypoplasia ye-eamel ;
- ukunyuswa kwezinto ezibangelwa yi- bruxism okanye ezinye izifo;
- kuluma.
IiVeners - i-pros and cons
"Ilungelo" i-microprosthetics inezinto ezixhamlayo:
- Ukugcina ixesha lesigulane (ukufakwa kwamacwecwe okutyebisa kwenziwa kwintetho e-1 kuphela kwidokotela wamazinyo);
- indleko yokubuyiselwa ixabiso elincinci kunezo zixhobo zeramic;
- Abacukuzi baqala ukulungiswa ngaphambi kokuhlobisa.
Olu hlobo lwe-microprosthesis lunokungaphumeleli. Eyona nto ibalulekileyo yile ngxaki elandelayo:
- Emva kwexesha, banokutshintsha ngombala;
- banamandla aphantsi xa kuthelekiswa neekeramic;
- Ubomi benkonzo emfutshane (ukususela kwiminyaka emi-3 ukuya kwe-7);
- usabela ngotywala (ziyabhujiswa phantsi kwefuthe lokusela izidyobisi kunye nezokuhlamba, eziqukethe i-ethanol).
Iiperamic veneers zineenzuzo ezilandelayo:
- amandla kunye nokuhlala;
- imibala eyahlukeneyo yokutya, ngoko ke akukho ndawo ibala kunye nebala elibonakalayo;
- kunceda ukuphinda uvuselele isakhiwo sezinyo, esibuyiselwe.
Ukungalunganga kweenkontileka ze-ceramic akuchazwanga kangako kunokuba kuhlanganiswe "ezichanekileyo" ezincinci. Okubaluleke kakhulu kwezi zixabiso eliphezulu lokubuyiselwa. Ukongezelela, ukungonakali kukuthi ukufakwa kwamacwecwe okuzibhena akunakwenziwa ngexesha. Ekutyelelweni kokuqala, udokotela wamazinyo ulungisa amazinyo aze enze umtsalane, kwaye i-veneer yesikhashana ifakwe kwi-incisor. Xa ugqirha a tyelela ugqirha kwakhona, i-microprosthesis efakweyo isusiwe, kwaye i-décor yokuhlala isigxina kwindawo yayo.
Ukufakwa kweenkontileka zeeramic
Inkqubo yonke ye-microprosthesis inokuhlukaniswa ngokwasemgangathweni ibe ngamanyathelo athile:
- I klinikhi. Udokotela wamazinyo uqhuba inkqubo yokuxilonga (uhlola isigxina somlomo) kwaye ukhetha ithoni ye-microprostheses. Izinyo ngokwayo linemihlaba eyahlukileyo e-3: isiseko, isiseko kunye nokusika. Ngamnye wabo unomthunzi wawo, ngoko umsebenzi wamazinyo wezinyoko kukufumana ukhetho jikelele.
- ILebhu. Ngokutsho kwenziwe iiplani zokucoca izicwangciso. Oku kwenza ukuba iteknoloji ye-ceramic veneers isondele kumazinyo angokwemvelo kunye nohlobo oluphezulu.
- I klinikhi. Kule nqanaba, i-microprosthesis iyalingwa okokuqala ize ifakwe.
Ukuguquka kwezinyo phantsi kwe-ceramic veneer
Le nkqubo iqhutyelwa ngokufakela i-microprostheses ngqo. Ukubonelela ngokucwangcisa i-ceramic veneers, emele amanyathelo alandelayo:
- Isicelo kwisibhakabhaka semida.
- Ukutshonkotha amahlangothi angqonge.
- Ukwenza umgca. Kule nqanaba, ukugaya kwenziwa ngo-1-2 mm.
- Ukunyangwa kwendawo yesifo.
- Ukugqitywa kokugqiba, okususa zonke iindawo ezibukhali.
Ukulungiswa kweemveliso zeramic
Emva kokuguqula amazinyo, ugqirha uyaqhubeka nokulungisa ii-microprostheses. Ukulungiswa kwezinto eziphathekayo kwangexesha elilodwa kuthintela iisayithi ezi-3:
- umqhina onzima;
- ipetamic;
- "Glue".
Ezi ndawo zihluke omnye komnye kumakhemikhali, ngoko ke, ukulungiswa okuqinileyo, unyango olulodwa ngamnye lufunekayo. I-veneer ifakwe ngokulandelayo:
- I-plate yokubhabisa ihlanganiswe ne-hydrofluoric acid. Ngenxa yolu msebenzi, iiporoshi zibonakala kwi-microprosthesis, eziza kubonelela ngokukhawuleza kwixesha elizayo.
- Izinyo ezibuyiselwayo ziphathwa ngequmrhu elincinci.
- I-asidi ekhethekileyo isetyenziswe kumphezulu we-cutter imizuzwana eyi-15.
- Lezinyo zihlanganiswe nge-primer kwaye zomiswe. Emva koko kusetyenziswa "iglue".
- Umgca wecala lombhobho wokuhlobisa uhlanganiswe kunye ne-fixer, kwaye i-veneer iqhotyoshelwe kwizinyo ezibuyiselwe. Isithethi "iglue" isuswe.
- Ukutshaya kunye nokwenza i-polymerization kwenziwa.
Iiperamic veneers - ubomi benkonzo
Ixesha lokusebenza lala macwecwe okuzibongela lide kuneloo-microprostheses edibeneyo . Ubomi benkonzo yeeramic veneers ngaphezu kweminyaka engama-20. Nangona kunjalo, kuphela ezo zigulane ezihambelana nezi ngcebiso zilandelayo zixhomekeke kulo:
- Ukutyelela umzinyo wamazinyo kabini ngonyaka;
- ugcine ucoceko;
- khusela amazinyo emagumbini (musa ukugaya amanqatha, musa ukuvula ibhotile).
Ngaba kunokwenzeka ukulungisa ama-veneers asele anikeziweyo?
Ugqirha unokwenza ukuguquka okukodwa kwala macwecwe, kodwa sithetha ngezilungiso ezincinane. Zonke izilungiso kufuneka zenziwe ngaphambi kokufakwa (kwisigaba esifanelekileyo). Kunikezelwa ukuba udokotela wamazinyo uyigugu langempela, akukho mfuneko yokulungiswa okuqhubekayo emva kofakelo. Oku kuboniswa ngokucacileyo ngumbonakude we-ceramic - iifoto ngaphambi nangemva.
