Xya-Year Retrospective Clinical Study validates Performance Of Monolithic Zirconia Crowns Rau Tshem Tawm Ib Feem Hniav Abutments

Ib xyoo - xyoo rov qab soj ntsuam kev tshawb fawb tau tso tawm ntev - lub sij hawm ua raws- cov ntaub ntawv ntawm monolithic zirconia crowns siv los ua abutments rau tshem tawm ib feem ntawm cov hniav hniav. Cov kev tshawb fawb tau taug qab tag nrho ntawm 297 monolithic zirconia soj ntsuam cov yas, sau cov ciaj sia taus ntawm 95.6% thiab qhov ua tiav ntawm 91.2% nyob rau lub sijhawm soj ntsuam.

Rau cov neeg mob uas haum nrog clasp - hom tshem tawm ib feem ntawm cov hniav cuav, lub abutment crowns dais nruam kev nyuaj siab los ntawm clasp tuav thiab rov occlusal loading, tso siab xav tau ntawm cov khoom puas thiab marginal kev ncaj ncees. Hlau-ceramic crowns tau ntev lawm qhov kev xaiv zoo rau cov kev kho kom rov zoo li qub. Txawm li cas los xij, PFM kev kho dua tshiab tuaj nrog qhov tsis zoo, xws li kev hloov xim hlau ntawm cov gingival margin, muaj peev xwm ua xua rau hlau thiab cov txiaj ntsig zoo nkauj.

Cov txiaj ntsig ntawm kev tshawb fawb pom tau tias monolithic zirconia tuaj yeem ua qhov kev txhim khu kev qha rau cov hlau tsoos -ceramic crowns rau kev txhawb nqa cov hniav hniav. Nws txoj kev puas tsuaj ruaj khov pab tiv thaiv cov yas tsis ua haujlwm nyob rau hauv lub zog rov ua haujlwm los ntawm kev tshem tawm ib feem ntawm cov hniav hniav clasps. Lub caij no, cov hlau- khoom pub dawb muab kev zoo nkauj zoo nkauj thiab tshem tawm cov hlau- ntsig txog biocompatibility kev txhawj xeeb.

Ntev -cov pov thawj kho mob ntev yog qhov tseem ceeb rau kev coj ua kev xaiv cov khoom siv hauv kev xyaum prosthodontic. Qhov no xya-cov ntaub ntawv xyoo no muab cov ntaub ntawv kho mob muaj zog rau cov kws kho mob thaum xaiv monolithic zirconia rau tshem tawm ib feem ntawm cov hniav hniav. Nws nthuav tawm tag nrho cov -cov kev xaiv ceramic rau cov neeg mob ib nrab ntawm cov edentulous thiab txhawb nqa dav dua ntawm cov hlau- cov kev daws teeb meem dawb hauv kev tshem tawm prosthodontics.
