Kev kho hniav zirconia abutments yog qhov tseem ceeb nruab nrab cov qauv hauv kev cog hniav, ua haujlwm raws li qhov tseem ceeb ntawm kev cog hniav osseointegrated kho hniav thiab qhov kawg ntawm kev kho hniav. Fabricated los ntawm zirconium dioxide (ZrO₂), siab -cov khoom siv ceramic, lawv tau ua kev zoo siab rau lawv qhov tshwj xeeb ua ke ntawm kev zoo nkauj thiab kev ntseeg tau ntawm kev ua haujlwm. Tsis zoo li cov tsoos hlau abutments, xws li cov uas ua los ntawm titanium, zirconia tus hniav tej yam ntuj tso- xim translucency enables superior ntxoov ntxoo, ua rau nws tshwj xeeb invaluable nyob rau hauv lub anterior cheeb tsam los yog pom luag zones qhov twg cov tshuaj pleev ib ce yog qhov tseem ceeb tshaj plaws.
Qhov zoo tshaj plaws yog lawv cov biocompatibility: zirconia yog cov tshuaj inert thiab hypoallergenic, txo qhov kev pheej hmoo ntawm peri- cog o los yog kev tsis haum tshuaj. Cov txheej txheem tsim khoom niaj hnub no, siv CAD / CAM thev naus laus zis, xyuas kom meej kev hloov kho kom haum rau ob qho tib si cog fixtures thiab cov pos hniav contours, txhim khu kev ruaj ntseg, marginal kev ncaj ncees, thiab cov ntaub so ntswg sib xyaw. Thaum keeb kwm raug thuam rau qhov qis dua qhov tawv tawv piv rau titanium, qib siab yttria- cov qauv zirconia ruaj khov tau txhim kho lub zog zoo, nthuav dav lawv siv rau ob qho tib si sab hauv thiab sab nrauv. Tsis tas li ntawd, lawv cov kev tiv thaiv corrosion thiab cov quav hniav tsim txhawb ntev - lub sij hawm cog qoob loo, cementing lawv lub luag hauj lwm raws li kev xaiv hauv kev zoo nkauj thiab kev cog hniav cog hniav.
