1. Tsis muaj kab dub ntawm lub gingival ntug, tsis muaj kev xav ntawm qhov loj, thiab tsis muaj gingival redness, o thiab los ntshav, yog li koj tuaj yeem hnov zoo tiag tiag tias cov hniav plooj (porcelain) tau loj hlob los ntawm koj cov pos hniav.
2. Lub translucency sib phim nrog cov hniav tiag tiag yog ntuj, thiab kev kho kom rov zoo nrog cov hniav zoo. Nws yog qhov nyuaj rau kev paub qhov txawv, thiab tsis muaj kev txaj muag ntawm "cov hniav ntsuab ci" nyob rau hauv lub teeb.
3. Nrog lub zog compressive piv rau cov hlau plooj (porcelain hniav), tsis tas yuav txhawj txog kev tawg ntawm cov plooj (porcelain).
4. Zirconia yog cov khoom siv roj ntsha zoo heev. Zoo biocompatibility, superior rau ntau yam hlau alloys, nrog rau kub. Zirconia tsis muaj qhov khaus thiab ua xua rau gingiva. Nws yog qhov tsim nyog siv rau hauv qhov ncauj kab noj hniav thiab tsis txhob muaj kev phiv xws li kev ua xua, khaus thiab corrosion los ntawm cov hlau hauv qhov ncauj kab noj hniav.
5. Muaj cov molars tsawg, thiab cov ntaub so ntswg tuaj yeem khaws cia kom ntau dua
6. Yog tias cov hniav hauv koj lub qhov ncauj yog cov plooj (porcelain fused to metal crowns), lawv yuav raug cuam tshuam los yog tshem tawm thaum koj yuav tsum tau kuaj X-ray, CT thiab MRI. Cov zirconia uas tsis yog xim hlau tsis muaj teeb meem rau X-ray. Tsuav yog cov zirconia porcelain fused rau cov hniav hlau, cov hniav tsis tas yuav tsum tau muab tshem tawm yav tom ntej thaum X-ray, CT thiab nuclear magnetic resonance kuaj yuav tsum, uas yuav txuag tau ntau yam teeb meem.
