Ukufaka uphawu ekudleni kwamazinyo kusetshenziswe ukwaziswa okukhethekile - okuhlanganiswe. Inezindawo ezidingekayo ukuze kubuyiselwe ubuqotho nombala wamazinyo. Ama-veneers ahlanganisiwe akhiwe ngendlela efanayo. Ngaphambilini, ikhwalithi yabo yayingenakuphakama kakhulu, futhi yayingaphansi kakhulu kwezici eziningi ezigumbini ze-porcelain ne-ceramic. I-composite yanamuhla isathuthukiswa njalo, ngaphezu kwalokho, ezinye zezinhlobo zayo nazo zinezicabha, zithola izici zayo ezinhle.
Ziyini izingxenye ezihlanganisiwe?
Uhlobo olucatshangelwe lokubuyiselwa kwamazinyo lungasetshenziswa ngezindlela ezimbili:
- i-orthopedic (engaqondile);
- ukwelashwa (ngokuqondile).
Esikhathini sokuqala, ubuchwepheshe bokubuyiselwa bufana nesikhumba se-ceramic - kusukela kumazinyo alungiselelwe, isikhunta sisusiwe, esiyisibonelo somsebenzi wezobuchwepheshe ekwenzeni izinsimbi ezincane zihlanganiswe ezindaweni zangaphambili nezokusika.
Izakhi ezihambelana ngokuqondile zenziwa ngudokotela ngqo ngesikhathi samukelwa, ngqo emazinyweni. Inzuzo yalesi buchwepheshe kungenzeka ukuthi ukuguqulwa koqweqwe lwawo koqweqwe lwawo kungabonakali. Ukucubungula kuphela leyo ngxenye yezinyo ngezinyawo lapho okuzohlanganiswa khona.
Kodwa-ke, izimboni ezingekho ngqo noma ze-orthopedic zinamandla amakhulu, ngoba ochwepheshe bamazinyo angathinta ama-patches ngezinga eliphezulu lokushisa nokucindezela, okuqedwa lapho kwenziwa ukubuyiswa ngqo emgodini womlomo.
Izinto ezihlanganisiwe zinezimo ezithile uma kuqhathaniswa ne-ceramics:
- ukugqoka okusheshayo (iminyaka engu-3-7);
- ushintsho kancane kancane ngombala;
- isidingo sokuvota njalo;
- ikhono lokudonsa ngaphansi kwethonya lokudla, i-nicotine neziphuzo;
- i-fragility ephezulu;
- ukulingana okulinganayo kwe-result final;
- ukumelana okuphansi kokuphuza utshwala;
- i-pigmentation emngceleni we-lining ne-koqweqwe lwawo wemvelo.
Naphezu kwalezi zinhlayiya ezingenhla, ama-veneers achazwa afakwe kaningi kunamakhemikhali. Lokhu kungenxa yezindleko eziphansi zamapuleti ahlanganisiwe, ashibhile cishe izikhathi ezingu-2.
Ngaphezu kwalokho, izitshalo eziqondiswayo zenziwa ngokuqondile kumenywa wamazinyo, okwesikhashana, kanti uma kudingeke ukuba uvakashele udokotela kabili bese ucela ukuba liningeni lenziwe.
Kubuyiselwa kanjani amazinyo nama-veneers amaningi?
Uma ubuchwepheshe be-orthopedic bokubuyiselwa kwamazinyo kusetshenziselwa, kusetshenziswe okokuqala ukugaya nokulungisa izindawo ezengeziwe (kufika ku-2.5 mm). Khona-ke ama-casts athathwa, ngokusho ukuthi ochwepheshe bamazinyo wenza izivini ezizimele. Ukuze uvikele koqweqwe lwawo ovulekile kanye ne-dentine, ama-pads okwesikhashana afakiwe.
Ngemuva kwezinsuku ezingu-7-10 lokhu kwenziwa okulandelayo:
- Ukuhlukaniswa kwezinyo okuzophathwa nge-latex, ukulungiselela kwayo.
- Isicelo sokubambelela emzimbeni wezinhlayiyana nezicubu eziphilayo.
- Ukufaka i-lining ngokucindezela ngokuqinile ngokumelene nezinyo.
- Gcina ukuqina (polymerization).
- Ukugaya nokupholisa amajoyina we-veneer nezinyo.
Indlela eqondile iyafana ngokuphelele nokufakwa kwamapayipi omzimba wama-orthopedic, kodwa akudingi umsebenzi wokuqala wezokwelapha zamazinyo. Udokotela wamazinyo ngesikhathi esamukelayo ugawula izindawo ezidingekayo, ukhetha umbala we-composite ukuze uhambisane nomthunzi wemvelo we-koqweqwe lwawo, futhi ubuyisele izinyo. Isiguli singakwazi ukulawula yonke inqubo.
Ungayinakekela kanjani izinsimbi ezihlanganisiwe?
Izinkinga ezikhethekile ezinhlanzekweni zomlomo azivuki.
Kwanele ukuxubha amazinyo akho izikhathi ezimbili ngosuku, kuphela ukunamathiswa kufanele kukhethwe ngaphandle kwezinhlayiya ezilahlayo. Kudingeka futhi ukususa i-plaque ezikhaleni zangaphandle ngokusebenzisa intambo ngesikhathi esifanele.
Ukwandisa ukuphila komsebenzi wabasebenzi abavela ku-composite, ungakwazi, uma ungawagcini ngokweqile ukudla okuqinile (i-caramel, nutshell), gwema ama-jab emhlathini.
Kudingeka futhi ukuvakashela udokotela wamazinyo ukuze uvinjelwe ngokujwayelekile, kanye nezinyanga ezingu-5-12.
Kwenzekani emazinyweni nasezinhlobonhlobo zemithi?
Ukufakwa kwe-qualitative kwe-linings kusuka enhlanganisweni akubandakanyi nemiphumela emibi. Inkinga kuphela isidingo sokuvuselelwa ngezikhathi zabasebenzi lapho bephela, mhlawumbe kusukela ochwepheshe ofanayo owakwenza ekuqaleni. Ngokuhamba kwesikhathi, kuzodingeka ukuthi ushintshele ekufakweni komqhele noma ezinye izinhlobo ze- prosthetics , ngoba ngokushintshwa kwezingqimba ezihlanganiswayo izinyo zigaxwa kakhulu.
