Rau kev kho dua tshiab hauv thaj chaw zoo nkauj, Zirconia crown txheej ntawm lub ntsej muag lossis tag nrho cov txheej txheem yuav muab cov txiaj ntsig zoo. Ob peb xyoos dhau los, txheej txheej txheej txheej plooj (porcelain) tau txhim kho tau zoo. Li no, Zirconia substructure uas tau muab txheej nrog cov plooj (porcelain) tsis zoo li yuav nti lossis tawg ntawm qhov occlusal lossis incisal.
Txawm li cas los xij, xav tias yuav tsum muaj lub zog siab tshaj plaws vim tias tus neeg mob muaj bruxism, hnyav tom, lossis qhov twg tsuas muaj kev txwv occlusal clearance. Nyob rau hauv tas li ntawd, ib tug monolithic crown tej zaum yuav zoo dua tom qab kev daws teeb meem. Ua tsaug rau cov tshiab monolithic zirconia (ib leeg, cov blocks ntawm zirconia), cov yas no yuav luag tsis tawg thiab tsim los tiv thaiv ib puag ncig hnyav tom qab ntawm lub qhov ncauj tiv taus zoo dua txhua yam - porcelain crowns. Vsmile ST White thiab Preshade Blocks Monolithic restorations muab qhov txiaj ntsig zoo dua.
· Yuav tsum muaj 1.0 mus rau 1.5 hli occlusal qhov tob txiav rau tag nrho -contour monolithic Zirconia crown kom ua tiav qhov tsim nyog occlusal anatomy.
· Koj yuav tsum tau xyuas kom meej 1.0 mus rau 1.5 hli ua haujlwm cusp tip txo, 0.5 hli gingival chamfer txo, 6 mus rau 8-degree taper rau cov phab ntsa axial, thiab 1.0 hli occlusal 1/3 txo qhov ua haujlwm cusp.
· Npaj ib lub 0.3 mus rau 0.5 hli chamfer rau lub marginal tsim kom tso cai rau ib tug ntau meej zeb ntawm pre-sintered zirconia.
