Kev taw qhia ntawm zirconia rau kev kho hniav kho hniav tso cai rau cov kws kho hniav muab cov hniav zoo nkauj, cov hniav - xim yas thiab cov txuas txuas ruaj khov rau cov neeg mob uas yog ob qho tib si zoo thiab muaj zog txaus los tiv thaiv occlusal rog.
Tab sis cov khoom siv yog qhov sib txawv ntawm cov porcelain thiab ceramics, tshwj xeeb tshaj yog nyob rau hauv cov tswv yim thiab cov cuab yeej xav tau los kho thiab polish ua ntej qhov kawg cementation.
Lub hom phiaj rau cov chaw kuaj hniav zoo tshaj plaws hauv kev tsim cov zirconia crowns thiab txuas hniav yog rau cov khoom kawg kom haum rau tus neeg mob lub qhov ncauj kom nws tsis xav tau kev hloov kho. Txawm li cas los xij, qhov tseeb yog tias txawm tias qhov zoo tshaj plaws zirconia restoration yuav xav tau qee qhov kev hloov kho, txawm tias me me.
Zirconia Adjustment Methods
Qee qhov kev hloov kho yog ua los ntawm polishing log lossis cov ntsiab lus.
Nyob rau hauv rooj plaub uas cov twj paj nruag tsis txaus, siv tsuas yog nplua thiab ntxiv - pob zeb diamond zoo. Siab-ceev, dej-cov tes tsho txias siv yav dhau los tsis pom zoo kom siv rau zirconia.
Hluav taws xob tesuas khiav ntawm qis qis RPMs (6,000–20,000) yog cov cuab yeej nyiam. Cov no tuav lub zog txaus ntawm qhov qeeb qeeb thiab tuaj yeem ua dej txias yog tias xav tau.
Kev sib txhuam- tuav pob zeb diamond burs muab thawj kauj ruam hauv kev hloov kho occlusal rau zirconia crowns. Lub teeb kov nrog cov nplua lossis nplua pob zeb diamond bur yog xav tau.
Lub siab dhau los lossis cua sov tsim los ntawm ib lub tes tsho tuaj yeem ua rau lub ntsej muag tsis zoo, thiab txawm tias tawg zirconia. Qhov ntawd tuaj yeem ua rau tsis ua tiav ntawm kev kho dua tshiab. Siv lub teeb cua thiab dej txau thaum hloov kho kom tsis txhob muaj cua sov thiab kev co.
Thaum hloov kho, sim ua kom tsis txhob ua qhov concavities hauv qhov chaw.
Lub hom phiaj yuav tsum yog kom muaj lub ntsej muag convex hla tag nrho kev kho dua tshiab. Ncaws pob, ncaj, lossis qe-zoo li pob zeb diamonds yog txhua yam tsim nyog siv rau zirconia.
Nco ntsoov tias, txawm tias muaj dej txias, qee qhov hluav taws xob tuaj yeem tshwm sim thaum hloov kho, vim qhov nyuaj ntawm cov khoom siv.
Thaum koj tau ua tiav tag nrho cov kev hloov kho occlusal thiab lub occlusion zoo tag nrho, lub zirconia yuav tsum tau polished rau lub siab luster. Kev tshawb fawb pom tau hais tias hnav ntawm qhov tawm tsam kev kho hniav yog qhov tshwm sim ntawm qhov ntxhib ntawm zirconia abrading tus hniav tawm tsam es tsis yog nws qhov nyuaj.
Yuav ua li cas polish zirconia
Tsis zoo li lwm cov ntaub ntawv, zirconia yuav tsis du thaum lub sij hawm ib txwm mastication, yog li polishing yog ib kauj ruam yuav tsum tau ua ntej zaum kawg cementation.
Txhawm rau polishing zirconia, koj yuav siv ntau lub log polishing, khob, lossis cov ntsiab lus pib nrog nruab nrab grit thiab txav mus rau qhov zoo ntxiv. Cov ntaub ntawv nruab nrab polish tshem tawm khawb los ntawm pob zeb diamond bur thaum hloov kho.
Qhov zoo thiab ntxiv - lub log zoo, lossis cov ntsiab lus, ntxiv tshem tawm cov kab kos thiab ua ib daim iav- zoo li ci. Yuav kom ua tiav lub siab luster, tsim nyog rau kev kho kom tiav, koj yuav siv polishing paste ua cov kauj ruam kawg.
Yog koj xav paub ntxiv, thov hu rau peb. Tus nqi -zoo milling burs ntawm zirconia pucks, iav ceramic, cog hlau, PMMA Blocks yog txhua yam muaj los ntawm peb. Tsis tas li ntawd, peb kuj tsim thiab tsim zirconia pucks, iav ceramics, pmma thiab lwm yam ntaub ntawv kho hniav CAD CAM.
