Qhov Transparency ntawm Zirconia kuaj li cas?
Mar 17, 2022
Lub pob tshab ntawm zirconia tau piav qhia los ntawm qhov ntsuas ntawm qhov txuas ntxiv tom qab qee qhov ntawm lub teeb dhau los ntawm qee qhov tuab ntawm zirconia.
Piv txwv li, yog tias lub teeb ntawm lub teeb ci ci rau ntawm lub phaj steel hlau nrog ib lub thickness, koj tsis tuaj yeem pom lub teeb nyem ntawm qhov kawg ntawm stainless hlau phaj, ces qhov kev xa tawm ntawm cov phaj hlau no yog 0 feem pua ; Yog tias lub khob pob tshab txaus, qhov siv ntawm lub teeb uas koj pom los ntawm lub khob yuav luag zoo ib yam li qhov koj pom tom qab tshem lub khob. , ces qhov kis ntawm lub iav phaj yog ze rau 100 feem pua.
Thaum pib, qhov kev xa tawm ntawm zirconia yog ntau tshaj 20 feem pua. Nrog rau kev siv zog tas li ntawm zirconia raw khoom manufacturers, nws muaj 35 feem pua, 44 feem pua, 47 feem pua, 50 feem pua, thiab hniav zirconia raw cov ntaub ntawv uas muaj ib tug tej lub zog kuj muaj. tshwm ib tom qab.
Feem ntau hais lus, lub teeb xa hluav taws xob ntawm zirconia blocks ntawm kev ua lag luam thiab cov khoom lag luam nrog cov khoom xa tawm zoo tib yam yog kwv yees li 30 feem pua -35 feem pua (1mm tuab qauv, 740nm wavelength), thiab peb-point dabtsi yog khoov zog yog 1200-1400MPa;
Rau cov khoom xa tawm siab, kev xa tawm yog li 40-45 feem pua, thiab peb-point dabtsi yog khoov lub zog yog 1000-1200MPa; rau ultra-high transmittance khoom, lub teeb transmittance yog hais txog 48-50 feem pua, thiab peb-point dabtsi yog khoov zog yog 600 -1000MPa. Kuj tseem muaj xim hlau zirconia uas yuav tsum tau muab ntxoov ntxoo rau kev cog qoob loo. Qhov no zirconia yuav tsum tau opaque heev, nrog lub teeb xa mus txog li 20 feem pua lossis tsawg dua, thiab lub zog ntawm 1000Mpa.
Aesthetically, peb xav tau zirconia nrog siab pob tshab, ze rau cov xim ntawm cov hniav ntuj, thiab qee zaum tsis tshua muaj opaque zirconia rau lub hom phiaj zoo nkauj. Kev lag luam xav tau muaj ntau haiv neeg, thiab cov chaw tsim khoom lag luam raw khoom thiab zirconia thaiv cov tuam txhab kuj tseem ua rau tsis muaj zog.
In order to make the zirconia restoration more beautiful and closer to the gradient color of the patient's natural teeth, most zirconium block manufacturers have also introduced multi-layered zirconia blocks (or gradient colors) to simulate the anatomy and histological structure of natural teeth. Even fluorescent zirconia blocks appear.
