Monolithic Zirconia Restoration

Monolithic zirconia yog lub ntsiab lus tseem ceeb ntawm txhua yam -ceramic khoom rau niaj hnub kho hniav hniav, nyiam los ntawm cov chaw kuaj mob thiab cov chaw kho mob thoob ntiaj teb. Ua los ntawm yttria-stabilized zirconia blocks, nws muab ultra-siab flexural zog tshaj 1000 MPa, tiv thaiv pob txha nyob rau hauv hnyav molar zom rog thiab haum rau bruxism cov neeg mobPMC. Tsis zoo li cov plooj (porcelain)-fused- rau- cov yas yas, nws tsis muaj hlau, tshem tawm cov pos hniav tsaus thiab muaj kev phom sij hlau. CAD/CAM milling ua rau cov duab zoo meej, txiav phau ntawv polishing yuam kev. Tshiab ntau- txheej zirconia txhim kho cov hniav zoo nkauj rau cov rooj plaub zoo nkauj sab hauv. Nws du polished nto tsim ib qho me me abrasion tiv thaiv cov hniav ntuj. Nrog kev pab cuam lub neej ntev thiab kev saib xyuas tsis tshua muaj, zirconia crowns thiab txuas hniav dominate posterior restorations hauv thoob ntiaj teb kev lag luam kho hniav.
