Npaj Kev Txum Tim Rov Qab Los
Sandblast kev kho dua tshiab nrog 20 microns ntawm aluminium oxide tom qab sim-hauv. Ntau tus kws kho hniav qhia txog sandblasting ntawm lub siab ntawm 2.5 bars (20-25 psi), kom qhov chaw yuav tsum tau sib khi ua me ntsis rougher yam tsis muaj qhov pom ntawm qhov muag liab qab. Pom tseeb, ib feem ntawm kev kho dua tshiab uas tsis xav tau kev sib txuas, xws li sab nraud ntawm lub veneer lossis lub dummy ntawm tus choj nplaum, yuav tsum tau tiv thaiv los ntawm cov nyhuv ntawm cov nplej abrasive. Nws kuj tseem pom zoo kom siv cov xim xim (waterproof marker cwj mem) rau thaj tsam kom sandblasted ua ntej ua haujlwm. Cov xim ploj thaum lub sij hawm sandblasting, ua rau nws yooj yim los xyuas tias tag nrho cov nplaum nplaum tau ua tiav lawm. Yog tias sandblasting ua tiav hauv chav kuaj ua ntej sim, ntxuav cov qaub ncaug nrog NaOCI thiab yaug nrog dej. Tsis txhob siv phosphoric acid los ntxuav.
Ntxuav nrog dej cawv thiab cua qhuav nrog cua tsis muaj roj.
Pretreat tus hniav
Tshem tawm qhov kev kho dua tshiab. Mechanically ntxuav cov hniav npaj nrog pumice muab tshuaj txhuam. Xyuas kom tseeb tias cov khoom seem (xws li cov cement ib ntus, desensitizers, astringents, tshuaj tua kab mob) raug tshem tawm tag nrho.
Siv cov cement thiab zaum tus hniav
Muab pov tseg ib qho me me ntawm cementonto lub mix-pad kom paub meej tias qhov sib tov zoo.
Muab cov cement ncaj qha rau hauv lub yas.
Nthuav lub rooj zaum nrog ntiv tes siab.
Huv huv
Tack qhov kho rau 1-2 vib nas this. Tsis txhob tshaj lub sij hawm kho tack uas tau pom zoo, txwv tsis pub, kev ntxuav yuav nyuaj heev. Rau lub sij hawm tswj curing, siv LED curing teeb.
Tshem tawm cov cement ntau dhau nrog lub scaler thaum tuav lub crown nyob rau hauv qhov chaw.
Kev kho zaum kawg
Lub teeb kho cov hniav rau 20 vib nas this ib qhov chaw los yog tos 6 feeb los ntawm qhov pib ntawm kev sib tov rau kev kho tsaus nti. Ua kom tiav thiab polish qhov kho dua tshiab raws li xav tau.
Teeb meem kom tsis txhob thaum lub sij hawm Cementation txheej txheem
Tsis txhob muaj kev sib cuag ntawm phosphoric acid nrog zirconia restoration thaum lub sij hawm cementation txheej txheem.Cov phosphate ion nyob rau hauv cov kua qaub zoo heev txo cov kev sib txuas rau zirconia.
Tsis txhob ntxuav cov hniav npaj nrog prophy paste.Cov emollients thiab fluoride nyob rau hauv ib co prophy pastes tuaj yeem ua rau tsis zoo thiab ua rau cov hniav tawm. Siv cov hmoov nplej ntawm pumice thiab dej.
Yog tias koj tawm tsam kom tshem tawm cov phosphate pawg los ntawm zirconia, nco ntsoov siv cov tshuaj xws li Ivoclean. Tso cov tshuaj rau ntawm lub kaus mom rau 20 vib nas this ua ntej yaug. Tom qab ntawd lub crown yuav tsum tau cua qhuav ua ntej nws npaj txhij rau kev sib txuas.
Yog tias koj puas tau ntsib teeb meem cementing nrog kev kho zirconia, tiv tauj peb ncaj qha los tham txog koj cov xwm txheej tshwj xeeb nrog peb pab pawg kws tshaj lij. Vsmile' s technicalsupportteam yog npaj los pab daws tej teeb meem hais txog zirconia crowns los yog bridgesand yuav ua hauj lwm nrog koj lub chaw ua hauj lwm los nrhiav kev daws qhov zoo tshaj plaws.
