Nrog rau kev mob siab rau kev tshawb nrhiav thiab kev txhim kho, peb lub khoos phom hniav tau muab siab hlo muab cov qauv ntxiv tom qab tso: PlZ, Porcelain Layered to Zirconia. Nrog cov qauv zog ntawm zirconia thiab cov esthetics ntawm cov plooj (veneers), peb PLZ Restorations muab kev zoo nkauj thiab lub zog zoo li tsis muaj lwm yam. Kev siv peb txoj kev tshaj lij, peb cov kev kuaj hniav zoo sib xws thiab ua tau zoo tsim ntau PLZ restorations nrog kev xav tau zoo heev.

Porcelain fij rau Zirconia combines ntshiab yttria-stabilized zirconia nrog txoj kev zoo nkauj ntawm ceramics. Qhov no pub rau cov tsoos tsho zoo nkauj thiab cov ntaub so ntswg zoo dua. Ceramics muaj nyob rau hauv 16 qhov ntxoov ntxoo thiab 4 tshuaj ntsuam ntxoov ntxoo, nrog kho kom zoo dua opalescent lub teeb kis tau tus mob thiab zoo heev blending muaj peev xwm.

Tag Nrho Monolithic Zirconia (FMZ)

Zirconia yog ib qhov kev sib haumxeeb Zirconia thiab kev kho tus choj tsis muaj porcelain overlay. Tshawb xyuas thiab tsim los ntawm koj cov lus pom zoo, cov tswv yim analog los yog cov tswv yim digital hauv peb lub Computer Pab Tau Software kom cov kev kho tshiab no tau los ua cov milled hauv peb cov cav tov.

Qhov kev ua haujlwm CAD / CAM no ua kom meej meej meej, thiab tsim tsis tau rau hauv txoj kab nrog koj cov kev nyiam rau cov neeg muaj kev sib txuas, kev sib thooj, thiab txhua qhov teeb meem. Peb ua tiav txhua lub tsev kom zoo zoo kom paub tseeb tias txoj kev sib sib zog nqus thiab txhuam hniav uas yuav tsis hnav cov hniav cuav. Peb cov tswv yim zoo nkauj tshaj plaws kos duab thiab glaze txhua chav tsev los xyuas qhov siab tshaj plaws aesthetics.

Cov kev qhia:
Tshaj tawm rau cov pos tom qab thiab cov kev kho choj. Tag contour zirconia pabcuam lwm txoj haujlwm rau bruxers thiab grinders thaum tus neeg mob tau tu tas lossis yuav ua kev puastsuaj rau lub cev PFM. Raws li cov kev ua kom zoo nkauj no zoo nkauj tshaj nkauj dua qub ntxiv thiab them nqi tsawg zog, lawv tau ua lwm txoj haujlwm nrov heev.

Contra-Indications:

Npaj
Peb nyiam ib tsoos chamfer npaj nrog tsawg 1.0 hli txo ntawm cov npoo thiab 2.0 hli ntawm anatomical occlusal yuav txo. Cov ntaub ntawv no tuaj yeem ua tau ntau dua, tab sis peb lub CAD / CAM milling systems tsim ntau dua cov kev npaj ntau hom kev npaj. Thov zam txhua yam tsis huv, thiab tsis txhob txhawj txog qhov kev npaj.

Cementation:

Tsis ntev los no, cov khoom tshiab tau raug tsim los ua kom qhov nyiaj ntawm cov ciaj ciam rau zirconia. Cov ntaub ntawv los ntawm cov kev tshawb fawb tau pom tseeb tias kev sib xyaw ua pa (50 micron Al2O3 ntawm 2.5 bar) thiab cov khoom xyaw uas muaj 10-methacryloyloxydecyl dihydrogen phosphate (MDP) monomer, ua tiav ib daim ntawv cog lus ntawm zirconia rau ib tus hniav npaj. Piv txwv, lub 3M Scotchbond Universal Adhesive muaj cov MDP monomer, uas optimizes nws tus kheej-etch kev ua tau zoo thaum siv nrog Relyx Ultimate adhesive cob cement.Zirconia raws li crowns thiab txuas hniav nrog zoo tuav tau cemented nrog hloov hloov iav iav.
