Tus yuam sij tseem ceeb ntawmZirconiathiabEmax (Lithium Disilicate iav-ceramic)Hauv txhua txoj kev ua kom tau yooj yim dua tuaj yeem ua rau pom qhov ntev ntawm qhov ntev xws liKev sib xyaw, kev ua tau zoo, thiab cov ntawv thov kev soj ntsuam:
1. Cov qauv thiab cov qauv
| Yam | Emax (Lithium Disilicate iav-ceramic) | Zirconia |
|---|---|---|
| Muaj pes tsawg | Muaj li ntawm quartz, lithium oxide, thiab phosphates, nrog rau ib qho kev siv lestalline ntawm lithium disilicate. | Zirconium Dioxide (Zro₂), feem ntau ruaj khov nrog yttrium (ySz technology (YSZ (YSZ Technology) los txhawb kev ruaj khov. |
| Lub tsev | Iav-Ceramic Matrix txhawb nqa los ntawm crystalline theem (lub luag haujlwm rau lub zog). | Ceramic Crystalline qauv (Tetravonal-rau-monoclinic theem hloov pauv kom tau nruj heev). |
2. Cov Khoom Siv Neeg Kho Tshuab
| Ntiag tug | Tus pa dawb | Zirconia |
|---|---|---|
| Lub zog flexural | 380-500 mpa (cia siab rau tuab rau kev ruaj khov; nquag mus chipping nyob rau hauv kev quab yuam ntau dhau). | 800-1200 MPa (Txawm ntau dua rau cov high-trans-translucess zirconia, ua kom cov qauv nyias nyias kom tiv taus cov khoom siv hnyav). |
| Hnav Tsis kam | Zoo, tab sis tsis txaus ntseeg mus rau Zirconia; tuaj yeem qhia txog kev siv hnav ntev ntev. | Excellent; resists abrasion even under posterior chewing forces (>1000n, zoo tagnrho rau cov hniav puas). |
| Yam ua tsis tau | Nruab nrab; Kev pheej hmoo ntawm chipping hauv cov neeg mob uas muaj bruxism lossis sib sib zog nqus. | Tshwj Xeeb; Heev tiv taus rau pob txha lov, haum rau bruxism lossis kev kho sab nrauv. |
3. Kev ua kom zoo nkauj (tseem ceeb rau sab hauv cov hniav)
| Yam | Tus pa dawb | Zirconia |
|---|---|---|
| Kev txhais ua | Kaw cov lus qhia ntuj nti ntuj, nrog lub teeb ntuj ci tawg thiab txheej duab tsos. | Tsoos Zaxonia yog opaque; High-translucess zirconia tau txhim kho translucencal tab sis tseem lag luam me ntsis tom qab emax. |
| Xim txuam | Ntau ntau xim gradients, yooj yim replicating kev hloov maj mam hues ntawm cov hniav ntuj. | Yuav tsum tau muab feeteding / glazing rau kev hloov xim; High-transc translucency versions mus rau hauv EMAX tab sis ntawm tus nqi siab dua. |
| Qhov chaw zoo tshaj plaws | Nyiam rautus me me hniav(Incisors, canines) qhov chaw ua kom zoo nkauj yog qhov tseem ceeb. | Zoo dua rau cov hniav posterior; High-translucess zirconia tuaj yeem siv anteriorly tab sis nrog me ntsis txo qis aesthetic finse. |
4. Hniav npaj (tsawg tsawg qhov peev xwm)
| Rov qab kho hom | Tus pa dawb | Zirconia |
|---|---|---|
| Txhua-ceramic yas | Yuav tsum tau1.5-2 hlintawm hniav txo (nyob ntawm tuab kom muaj zog). | Xav tau xwb0.5-1 hlintawm kev txo (khaws lub zog siab txawm nyob hauv cov khoom nyias nyias). |
| Porcelain Veneer | Yuav tuaj yeem txo qis kev phem (0.3-0,5 mm txo) tab sis nrog lub zog tsawg. | Yuav tsum tau0.8-1.5 hliTxo (rigidity thov kom txaus thickness rau kev ruaj khov). |
5. Kev kuaj mob qhia thiab kev ua haujlwm ntev
| Yam | Tus pa dawb | Zirconia |
|---|---|---|
| Cov Hniav Haum | Anterior cov hniav (ua kom zoo nkauj ua ntej) lossis cov ua haujlwm tshaj tawm nrog qhov tshwm sim ib txwm muaj. | Posterior cov hniav (zom cov rog siab), cov neeg mob uas muaj bruxism, lossis abutments rau txuas hniav sib tw. |
| Kev muaj peev xwm | 10-15 xyoo (tej zaum yuav xav hloov vim hnav los yog chipping). | Tshaj 20 xyoo (superior stability; tsawg dua cov pob txha tsawg nrog kev kho kom zoo). |
| Tshwj Xeeb | Qhov zoo tshaj plaws rau luag-thaj chaw ua kom yooj yim xav tau kev ua kom zoo li qub txeeg qub teg. | Pom zoo rau cov ntaub ntawv uas xav tau lub zog siab tshaj plaws (piv txwv li, cov roj ntsuab molar, bruxism). |
6. Tus nqi thiab biocompatibility
| Yam | Tus pa dawb | Zirconia |
|---|---|---|
| Tus nqi | Feem ntau kim dua (vim yog cov ntaub qhuab qhia ua kom zoo dua qub thiab zoo dua qub). | Txheem zirconia muaj nqis pheej yig dua; High-transc translucency versions mus rau hauv Paxax nyob rau hauv tus nqi. |
| Biocompatibility | Zoo heev (tsis muaj kev txwv tawm iav-ceramic dlej). | Tshwj (dav siv nyob rau hauv orthopedic kev cog lus; cov ntaub ntawv muaj tshuaj ntsuam uas txhawb nqa kev nyab xeeb). |
Ntsiab lus: Yuav xaiv li cas?
Ua ntej kev ua kom zoo rau sab hauv cov hniav: Xaiv Emax (ntuj translucolency thiab xim gradient).
Ua ntej lub zog rau cov hniav posterior: Xaiv Zirconia (tawm tsam hnyav zom zom ua).
Kev Txiav Teeb Meem: Txheem zirconia rau cov hniav posterior; High-translucess zirconia lossis emax rau sab hauv cov hniav yog tias siv nyiaj txiag.
Cov neeg mob uas muaj bruxism: Zirconia yog qhov yuav tsum tau ua (Superagn Paracture Refortance).
