Lub neej ntev npaum li cas ntawm cov hniav Txhuas-ceramic?

Raws li cov ntaub ntawv sib txawv, txhua tus hniav-ceramic tuaj yeem muab faib ua ob hom:

1. Txhua-ceramic hniav ntawm iav ceramics. Xws li: kub tuag-casting porcelain crowns, iav-permeable porcelain crowns, thiab iav-ceramic crowns polished los ntawm CAD / CAM technology.

2. Alumina thiab zirconia tag nrho-tej hub hniav tas los thov CAD / CAM technology zom cov alumina thiab zirconia puab crowns, thiab ces tus txheej txheej ntawm iav yog ntxiv los ntawm fawm kib iav tshuab ua kom cov tas tag nrho-tej hub hniav los yog tsis muaj txheej txheej Tag Nrho zirconium crown decorated nrog porcelain.

Feem ntau hais lus, tag nrho cov hniav-ceramic tau muab faib ua ob pawg saum toj no, thiab vim yog cov khoom siv muaj zog thiab muaj zog ruaj khov, lawv tau tso lub hauv paus rau kev hnav ntev. Cov hniav plooj (porcelain) uas tau ua nruj me ntsis, ua qauv thiab ua haujlwm kom raug, tsim thiab tsim los ntawm cov kws kho mob tsis tu ncua tuaj yeem siv rau ntau tshaj 20 xyoo tom qab tshawb fawb txog cov hniav zoo tib yam porcelain. Lub neej ncua sij hawm ntawm tag nrho cov-ceramic cov hniav yog ntev dua li cov hniav porcelain zoo tib yam. Yog tias koj saib xyuas koj cov hniav tag nrho-ceramic zoo tib yam, koj tuaj yeem ua neej nyob ntev dua thiab tseem nyob mus ib txhis. Hloov pauv, lub neej ncua ntawm tag nrho cov-ceramic cov hniav yuav raug txo.
