Ultra-Translucent Zirconia

Cov tom ntej Evolution hauv Zirconia

Cov khoom siv tshiab zirconia combines cov kev paub zoo ntawm zirconia uas muaj qhov tseem ceeb nce hauv kev txhais lus (49% translucency), ua zoo tagnrho rau sab nrauv thiab posterior daim ntawv thov mus rau 3 chav tsev bridgework nyob rau hauv tag nrho cov ntawv tuav. Cov mob biocompatible, zirconia yog ib qho khoom siv zoo rau hnub no txoj kev kho hniav, muab cov lus ntawm ib lub lithium disilicate thaum tuav lub zog ntawm zirconia (720 MPa). Tsis zoo li tam sim no iav ceramics, zirconia pub rau ib tus txhag cia plaub ntug ua vim nws lub zog siab. Cov kws kho hniav tsis tau xaiv ntawm cov tshuaj zirconia thiab lithium disilicate ... zirconia muaj ob lub zog thiab kev zoo nkauj!

Kev mob ntsig txog mob

Zirconia raug qhia rau tib lub yas thiab 3 chav tsev bridgework nyob rau hauv tag nrho cov ntawv tuav.

Npaj Ua

Zirconia yuav tsum tau noj hniav dua li qhov yuav tsum tau ua rau lithium disilicate. Qhov zoo tshaj plaws, .8 hli chamfer los yog sib npaug xub xub pwg npaj, txawm li cas los xij taum plaub ntug tau txais kev pom zoo nrog 1.0 - 1.5 hli txhaj raug txo kom tsawg.

Cementation

Cov kev tshawb fawb tsis ntev los no tau pom tias qaub ncaug tuaj yeem tiv thaiv kev zirconia ntawm cov khoom. Thaum zirconia crown los yog tus choj raug sim nyob hauv tus neeg mob lub qhov ncauj thiab los ntawm kev sib chwv nrog qaub ncaug, phosphate pawg hauv cov qaub ncaug khi rau zirconia oxide thiab tsis tuaj yeem muab yaug nrog dej. Sim siv cov phosphoric acid (uas muaj ntau hom phosphate) kom 'ntxuav tawm' cov qaub ncaug tsuas ua rau qhov teebmeem zuj zus.

Yuav kom tshem tawm cov qaub ncaug, nws yog tam sim no pom tias tom qab sim ua ntej thiab ua ntej priming, lub yas yuav tsum tau ntxuav nrog Ivoclean, zirconia oxide tov los ntawm Ivoclar Vivadent. Qhov zirconia oxide kua no tau muab tso rau hauv qhov kev kho kom rov qab rau 20 feeb thiab tom qab ntawd yaug tawm. Vim yog qhov loj ntawm zirconia oxide nyob rau hauv Ivoclean, nws ua raws li lub sponge thiab khi rau cov phosphate pawg uas tau yav dhau los ua ke rau kev kho kom rov qab.

Piav Pom Kev Cementation Protocol:
1. Sim-nyob rau hauv zirconia-restoration
2. Tso cov qaub ncaug tawm ntawm cov dej rov qab
3. Muab Ivoclean nyob rau hauv restoration rau 20 feeb,
yaug thiab qhuav
4. Siv cov tshuaj xub pwm thiab ces cement nrog cov khoom ntawm
koj xaiv

Cementation Cov lus pom zoo:
• Qiv & Choj los yog ib lub khob iav uas muaj yees zoo dua
• Rau kev npaj luv luv los yog tshaj tawm, siv ib qho tshuaj cement

Xov thiab Polishing

peb xav kom cov ZR khoom rau txoj kab thiab cov khoom zirconia khoom. Qhov kev ua ob-theem no tso cai rau koj kom ua tiav qhov siab tshaj plaws smoothness, mus pab txhawb koj txoj kev txhim kho qhov ntev thiab kom tsis txhob muaj kev tawm tsam kev tawm tsam.

Tseem ceeb: Nco ntsoov siv dej txaus thaum kho.
