Yttria stabilized zirconia (Hauv lub tuam txhab peb feem ntau xa mus rau nws li HTPC) yog cov khoom siv feem ntau siv hauv kev kho hniav, tshwj xeeb tshaj yog rau kev kho hniav kho hniav zoo li cov yas, txuas hniav, thiab cog abutments. Nws yog ib hom zirconia uas tau ruaj khov nrog yttria (yttrium oxide). Qhov sib ntxiv ntawm yttria txhim kho cov khoom siv kho tshuab thiab txhim kho kev ruaj ntseg ntawm zirconia.

Lub zog thiab Durability: Yttria stabilized zirconia (HTPC) muaj lub zog flexural thiab compressive zog, ua rau nws tsim nyog rau kev kho hniav uas yuav tsum tau ua kom lub neej ntev thiab ua haujlwm zom zom. Nws muaj cov khoom siv kho tshuab zoo dua piv rau lwm cov ntaub ntawv kho hniav xws li porcelain lossis hlau.
Kev zoo nkauj: Yttria stabilized zirconia (HTPC) tuaj yeem ua tau zoo heev, tso cai rau lub teeb kis tau zoo, uas ua rau muaj kev zoo nkauj ntawm kev kho hniav kho hniav. Nws tuaj yeem ua qhov ntxoov ntxoo-muab rau tus neeg mob cov hniav ntuj, muab lub ntsej muag zoo nkauj dua.
Biocompatibility: Yttria stabilized zirconia (HTPC) yog biocompatible, txhais tau tias nws yog suav tias yog kev nyab xeeb thiab sib haum nrog cov ntaub so ntswg qhov ncauj. Nws feem ntau tsis ua rau muaj kev tsis haum tshuaj lossis cov ntaub so ntswg tsis zoo.
CAD/CAM Milling: Yttria stabilized zirconia blocks (HTPC) tuaj yeem milled siv computer-aided tsim thiab computer-aided manufacturing (CAD/CAM) systems los fabricate meej thiab kev cai kho hniav kho hniav. Cov khoom tso cai rau kev milling kom raug thiab cov ncauj lus kom ntxaws.
Sintering: Yttria stabilized zirconia (HTPC) yuav tsum muaj cov txheej txheem sintering tshwj xeeb tom qab milling kom ua tiav nws lub zog kawg thiab zoo nkauj. Sintering tsis, xws li kub, lub sij hawm, thiab txias npaum li cas, yuav tsum tau ua tib zoo tswj kom zoo zoo.
Cementation: Yttria stabilized zirconia (HTPC) kev kho kom rov qab tuaj yeem ua cemented siv cov nplaum resin cements lossis tus kheej nplaum resin cements. Kev kho kom zoo thiab cov txheej txheem cementation yuav tsum tau ua raws li kom muaj kev sib raug zoo thiab ruaj khov.
Lub neej ntev: Yttria stabilized zirconia (HTPC) kho hniav kho hniav yog paub txog lawv cov kav ntev thiab kev ua haujlwm ntev. Thaum tu thiab tu kom zoo, lawv tuaj yeem nyob tau ntau xyoo.
Tus nqi: Yttria stabilized zirconia (HTPC) restorations yuav kim dua li cov tsoos hlau-ceramic restorations vim tus nqi siab ntawm cov khoom thiab cov txheej txheem tsim khoom ntxiv. Txawm li cas los xij, cov txiaj ntsig mus sij hawm ntev thiab kev zoo nkauj muab los ntawm Yttria stabilized zirconia restorations tuaj yeem ua pov thawj kev nqis peev rau ntau tus neeg mob.
