Muaj ntau ntau yam los txiav txim siab thaum xaiv cov hniav zoo tshaj plaws, suav nrog txoj haujlwm ntawm tus hniav hauv qhov ncauj, kev ua kom zoo nkauj, durability, thiab peev nyiaj. Ntawm no yog qhov kev tawg ntawm qee cov ntaub ntawv yas crown thiab lawv cov khoom kom pab koj ua qhov kev txiav txim siab paub tias:
1. Lub plooj Cords
Aesthetics:
Plooj (veneers) crowns yog qhov txaus siab rau lawv cov kev ua kom zoo nkauj. Lawv tuaj yeem ua kom pom tseeb li cas - matched rau tus neeg mob ntuj, feem ntau siv cov lus qhia ntxoov ntxoo zoo li cov lus qhia ntxoov ntxoo. Cov khoom txhais tau ib lub translucbency uas zoo ib yam li cov txha hniav txha hniav txhuam hniav uas muaj cov hniav uas muaj cov hniav zoo nkauj rau sab xub ntiag uas pom yog qhov tseem ceeb. Nyob rau hauv pem hauv ntej ntawm lub qhov ncauj, plooj (veneers) crows sib xyaw ua ke nrog cov creditionally nrog cov creding critition, nthuav qhia ib tug heev muaj tseeb thiab zoo nkauj.
Txawm li cas los xij, cov hlau cords tuaj yeem zaum dhau sijhawm, tshwj xeeb yog tus neeg mob muaj tus cwj pwm ntawm kev sib tsoo lawv cov hniav. Tsis tas li, qee kis, yog tias lub kaus mom tsis yog sib raug zoo lossis muaj cov ntoo me me, cov yas yuav nti lossis tawg, cuam tshuam rau tag nrho cov kev zoo nkauj.
Qhov ruaj khov:
Thaum lub plooj (vencelain muaj zog, nws yog qhov loj tshaj piv rau qee cov ntaub ntawv. Nws yuav tsis tiv thaiv cov rog muaj zog muaj zog nrog rau lwm cov ntaub ntawv, yog li nws yog feem ntau zoo dua rau cov hniav lossis thaj chaw uas muaj qhov qis dua. Rau cov hniav rov qab uas yuav raug rau ntau cov rog tom ntau, cov kab hlau plooj (vencelain) yuav muaj kev pheej hmoo ntau dua yog tias lawv tsis muaj kev txhawb nqa.
Lub neej ntawm daim phiaj hniav porcelain tuaj yeem sib txawv nyob ntawm cov lus zoo xws li hloov kho tus kheej, tab sis nyob rau nruab nrab, lub porcelein crown tej zaum yuav tau hloov lossis rov qab los ntawm ob peb xyoos vim kev puas tsuaj lossis puas.
Biocompatibility:
Cov plooj (vencelain feem ntau biocompible thiab tsis ua rau kev ua xua feem ntau ntawm cov neeg mob. Nws yog cov tshuaj ruaj khov nyob hauv qhov chaw ntawm qhov ncauj thiab tsis tso cov tshuaj ua phem. Txawm li cas los xij, thaum porcelainain yog fused rau hlau hlau (xws li daim phiaj av ntawm biecompatibility, xws li} hlau hlau, xws li cov neeg siv tsis haum ntawm cov neeg yuav muaj feem ntau li Nickel.
Nqi:
Tus nqi ntawm daim phiaj hniav plooj cooj. Nyob ntawm qhov xwm txheej xws li qhov nyuaj ntawm cov ntaub ntawv siv, qhov chaw ntawm lub chaw kho hniav. Nyob rau hauv dav dav, plooj (veneers) tus nqi piv rau qee qhov kev xaiv, tab sis cov nqi yuav nce ntxiv yog tias muaj ntau lub hau yas yuav tsum muaj.
2.Zirconia crowns
Aesthetics:

Qhov ruaj khov:
Nws muaj lub zog siab zoo, feem ntau ntawm 900 thiab 1500 MPA, thiab tuaj yeem tiv thaiv muaj zog muaj zog. Yog li no, zirconia crown yog qhov kev xaiv zoo dua rau cov hniav posterior uas muaj kev lag luam zoo. Piv rau cov kab corsain, zirconia cov hniav yog qhov tsis tshua muaj qhov nti, tawg lossis tawg, ua rau lawv qhov kev rov qab ua kom ruaj khov dua.
Lub ntev - Term detability ntawm cov kev tiv thaiv zirconia kuj yog vim lawv tsis kam hnav thiab lawv lub peev xwm los tswj kev ua kev ncaj ncees nyob rau lub sijhawm.
Biocompatibility:
Zirconium oxide yog biocompice heev. Nws yog tshuaj lom neeg nyob rau hauv qhov chaw ntawm qhov ncauj, tsis tso tawm cov tshuaj phem, thiab tsis ua kev ua xua fab hauv cov neeg mob feem ntau. Nws muaj cov ntaub ntawv zoo ntawm kev saib xyuas kev noj qab haus huv ntawm ib puag ncig cov pos hniav thiab tau zoo siab rau los ntawm tib neeg lub cev.
Nqi:
Zirconium oxide crowns feem ntau kim dua li cov txheej txheem cov khoom lag luam (feem ntau muaj cov cuab yeej siv ntau dua (cov khoom siv tshwj xeeb xws li Sintering Furnaces. Txawm li cas los xij, feem ntau, lub durability thiab lwm yam zoo ntawm zirconia cov yas yuav ua rau lawv tus nqi siab dua.

3.Qhov crowns
Aesthetics:
Hlau crown, xws li cov uas ua los ntawm kub alloys, muaj qhov txawv txav me me. Thaum lawv tsis yog ua kom zoo nkauj li plooj (pob zeb Rau cov hniav rov qab, tshwj xeeb tshaj yog thaum kev ua kom loog tsis yog qhov kev txhawj xeeb thawj, cov hlau nplaum hlau yog qhov kev xaiv tau zoo.
Qee cov hlau cov hlau kuj tseem tuaj yeem ua rau muaj cov phiaj xwm kev nyuaj ntxiv thiab cov teeb meem ntxiv, xws li cov teeb meem tseem ceeb, xws li cov veneer) veneer yuav poob rau lub sijhawm.
Qhov ruaj khov:
Hlau yas yog cov muaj zog ruaj khov. Piv txwv li, kub alloys yog ducile thiab muaj zog, thiab tuaj yeem tiv taus kev zom zom kom muaj zog ntev. Lawv hnav {- tiv taus thiab muaj lub neej ntev ntev, piv rau qee cov ntaub ntawv. Cov hlau nplaum hlau kuj tsis tshua muaj kev sib tsoo lossis tawg ua ib txwm siv.
