Izinyo le-pivot lingumuthi wamazinyo owenzelwe ngokuhlanganyela udokotela wamazinyo nochwepheshe wamazinyo. Ingena esikhundleni sezinyo elinezimpande ezisesimweni esanele ngokwanele ukufaka induku, ngokuvamile okuyinsimbi, yona uqobo esekela ingxenye ephezulu ebizwa ngokuthi umqhele.

Leli zinyo le-pivot lingenziwa ngezindlela ezimbili:

- Ku-block eyodwa ethe njo emigodini yezimpande.

- Ezingxenyeni ezimbili: isiqu, bese kuba umqhele we-ceramic. Le ndlela inconywa kakhulu njengoba uhlelo luthatha kangcono izingcindezi zokuhlafuna. 

Izinyo le-pivot kungenzeka lapho izinyo lemvelo lilimele kangako ukuthi ingxenye yalo ebonakalayo, umqhele, ayisakwazi ukwakhiwa ngokufaka okulula noma ukugcwaliswa kwensimbi. Ngakho-ke kuyadingeka ukwengeza ihange lapho umqhele uzohlala khona. Izinkomba eziyinhloko zezinyo le-pivot, nomqhele ngokujwayelekile, yilezi¹ :

• Ukuhlukumezeka noma ukuphuka kukhulu kakhulu kunoma yikuphi ukwakhiwa kabusha
• Ukubola okuthuthukile
• Ukugqoka kwamazinyo okuphawulekayo
• I-dyschromia enamandla
• Ukungahambi kahle kwezinyo.

Amakhanda yizinto zokufakelwa ezingaguquguquki ezizomboza ingxenye engenhla yezinyo ukubuyisela i-morphology yabo yasekuqaleni. Zingenziwa kuzicubu zamazinyo ezisele (ngenxa yokulungiswa) noma zilungiswe "kusigaxa sokufakelwa" sensimbi noma se-ceramic: i-pivot, ebizwa nangokuthi okuthunyelwe. Kulokhu kokugcina, umqhele awunanyathiswanga, kepha ubekwa uphawu lwe-pivot olushelele empandeni yezinyo.

Kunezinhlobo ezahlukahlukene zemiqhele ngokuya ngesibonakaliso, kepha futhi nangokuhleleka kobuhle nangokomnotho okunikezwa umuntu odinga ukufakwa komqhele.

Imiqhele yabalingisi (CC). Kwenziwe ngokusakaza ingxubevange encibilikisiwe, ngokuqinisekile kungubuhle obuncane futhi kubiza kakhulu.

Imiqhele ehlanganisiwe. Le miqhele ihlanganisa izinto ezimbili: i-alloy ne-ceramic. Emiqhele egqokiwe ye-vestibular (VIC), indawo evundlisiwe imbozwe nge-ceramic. Emiqhele yensimbi eyenziwe ngobumba, i-ceramic imboza ngokuphelele ubuso bamazinyo. Zibukeka kahle kakhulu futhi ngokusobala zibiza kakhulu.

Yonke imiqhele ye-ceramic. Njengoba igama labo liphakamisa, le miqhele yenziwe ngokuphelele nge-ceramic, nayo emelana kakhulu. Bangubuhle kakhulu futhi babiza kakhulu.

Isimo sobuhle akusona kuphela umbandela, kepha: umqhele kufanele uhlangabezane nezidingo zomlomo womlomo. Ukwakhiwa kabusha kwensimbi njengamanje kusetshenziswa kabanzi ngaphandle kohlangothi lwayo olungabukeki: izakhiwo zemishini kanye nokwenza lula kokukhiqizwa elebhu kuyazikhulumela! Endabeni yezinyo le-pivot, lo mqhele empeleni uhlotshaniswa nesiphunzi samanga sokufakelwa silungisiwe, siqinisiwe noma sifakwa empandeni.

Lapho izinyo lonakele kakhulu, kulandela ukubola okukhulu noma ukushaqeka okunamandla, ukuvuthwa kwesimame kuvame ukwenziwa ukunqanda ukuqhubeka kokutheleleka nokususa noma yikuphi ukuzwela kwezinyo. Lokhu ngokuyisisekelo kuhilela ukususa izinzwa nemithambo yegazi kuzinyo elinegciwane nokuxhuma imisele.

Uma izinyo lonakele kancane, lifake ukuze lithole ukwakheka okujwayelekile, lithathe umbono walo bese uphonsa insimbi noma i-ceramic-metal prosthesis.

Kepha uma izinyo lonakaliswe ngokwakhiwa kakhulu, kuyadingeka ukuthi ubambise i-pivots eyodwa noma ezimbili empandeni ukusimamisa umqhele wakusasa. Sikhuluma nge- "inlay-core" ukukhomba lesi siphunzi esingamanga esivaliwe ngosimende.

Kudingeka izikhathi ezimbili ukwenza lo msebenzi.

Gwema lapho kungenzeka. Isinqumo sokuthwesa izinyo ngehange lezimpande kufanele sithathwe ngemuva kokubhekisisa kahle.². Ukufezeka kwamahange akukhona ngaphandle kwezingozi futhi kufaka ukulahleka kwento okwenza izinyo libe buthakathaka. Impela, ngokungafani nenkolelo yenkani, akukhona ukuqothulwa kwamazinyo okungalenza libe buthakathaka ngokwengeziwe.^{3 4}, kodwa ukulahleka kwezinto okubangelwa ukubola noma ngokuhlinzwa. Uma kunokwenzeka, udokotela kufanele aphendukele ekwakhiweni kabusha kwezinyo elincishwe umqhele oncishayo kancane futhi alwele ukonga izicubu eziningi.

Itafula lezinyo le-pivot. Ukulahleka kwezicubu ezixhunywe ekubambeni kwama-pivots kungaholela ekunciphiseni ukumelana nezingcindezi ezixhumene nokuvalwa, okwandisa ubungozi bokuqhekeka. Uma lokhu kwenzeka, izinyo liyaphuma. Ngenkathi silinde ifayela le- ukuqokwa kudokotela wamazinyo (kubalulekile!), kungakuhle ukuthi ubeke esikhundleni sayo ngokunethezeka ngemuva kokunakekela ukuhlanza impande (i-mouthwash kanye nejet yamazinyo zanele) nenduku ye-pivot. Noma kunjalo kuzofanele isuswe ngesikhathi sokudla ukugwema ukuyigwinya: akunakwenzeka ukuthi kusekele ukungezwani kokuhlafuna.  

Uma impande yakho ihlale ingashintshi, uzokwabelwa ipivot entsha.  

Ngakolunye uhlangothi, uma impande yakho ithelelekile noma iphukile, kuzodingeka ucabange ngokufakwa kwamazinyo noma ibhuloho.
