Lub luag haujlwm ntawm zirconia tag nrho cov hniav ceramic hauv kev kho kom zoo nkauj

Lub refractive index, translucency thiab enamel ntawm zirconia tag nrho -ceramic crown yog heev ze rau enamel, thiab lub hauv paus crown ntawm crown yog dawb thiab nto yog du, yog li nws cov duab yog ntau natural thiab tiag. Zirconia tsis muaj kab dub ntawm ntug ntawm lub yas. Cov xim ruaj khov, Tsis muaj xim hloov tau yooj yim, ruaj thiab hnav, tsis muaj kev tsis haum tshuaj, zoo tag nrho cov tsos. Txoj kev tshawb no tseem qhia tau hais tias qhov tshwm sim ntawm qhov tsis zoo tshwm sim ntawm kev kho kom zoo nkauj nrog zirconia tag nrho -ceramic hniav tau txo qis. Zirconia tag nrho-cov hniav ceramic tsis txhawb cov pos hniav thiab muaj qhov tshwm sim tsawg ntawm qhov mob, yog li txo qhov tshwm sim ntawm cov hniav caries.
