Zirconia

Zitsulo-ceramic akorona ntchito mano kumapeto kwa nthawi yaitali ndipo ndithu bwinobwino. Iwo cholimba, koma iwo ali m'poipira mwa mawu maonekedwe. moyo dzino zotsatira analenga pang'ono okha monga ngati si mosamala kusankha mitundu zoumbaumba. Ichi ndi chifukwa chimango zitsulo ali mtundu wake womwe, zonse chigoba kuti sikuti ntchito. Wina sangathe a ziwalo izi - mavuto zitsulo pa usinini. akorona Ceramic mulibe zovuta izi, koma iwo sali wamphamvu kwambiri, pafupifupi korona ndi chimango zitsulo.

Mu mano ano, kusankha zipangizo prosthesis ya n'komwe osati magwiridwe ake, komanso aesthetics. Zirconia, amene ntchito yopanga mu zochiritsira kuyambira 1969, ambiri ntchito kupanga ziwalo mano. Nthawi zina, popanda kugwiritsa ntchito dzina lake mankhwala enieni, zinthu izi chabe otchedwa zirconium. Mu mano, kaŵirikaŵiri ntchito kupangira nyama akorona mano.

Korona wa zirconium dioxide, angathe kupatsira kuwala, mofanana ndi translucency mano, choncho yang'anani zachilengedwe ndipo si wosiyana mano zachilengedwe. Pankhaniyi ali durability ofanana ndi mphamvu zachifumu zitsulo.

Mu kupanga Mano ovekera m'munsi korona zambiri smelted. Korona zirconia - kupatulapo. A sikana laser anatsimikiza mwa mawonekedwe a korona m'tsogolo, deta kukonzedwa a kompyuta, ndi ziwembu kompyuta chitsanzo korona. Kenako zida wapadera, monga anakonzeratu kompyuta anaphedwa kudula kuchokera chidutswa umodzi wa zirconia. Korona chifukwa ali ndi mkulu mwatsatanetsatane komanso amaonetsetsa maonekedwe wangwiro.

Posachedwapa, korona wa zinthu ceramic waikidwa yekha pa mano kutsogolo, ndiyo ntchito zawo chifukwa, kani, zifukwa zokongoletsa kuposa tiligwiritse ntchito. Kugwiritsa zirconia alibe malire. Ndi abwino kwa zapambuyo apulasitiki ndi mano zapambuyo, ndi zikulumikizana bwino ndi amadzala. Kugwiritsa ntchito njira imeneyi, chopangidwa akorona wosakwatiwa ndipo anagwira milatho. Zirconia - hypoallergenic ndipo mwamtheradi bioinert mwachibale kwa zinthu thupi Choncho ntchito yopanga ngakhale sachedwa thupi lawo siligwirizana odwala. Malinga ndi digiri ya Bioinert anaposa ngakhale golide.

Zirconia ali mkulu matenthedwe katundu kutchinjiriza, kotero korona kuteteza mano kuchokera kutentha. Ichi ndi dalitso kwa anthu odwala amene mano amazindikira chakudya otentha ndi ozizira.

Mtembo korona ndi zoonda, wochindikala ndi 0.4 okha mm. Choncho, lightness dongosolo la Mano ovekera amapereka pafupifupi yomweyo zizolowezi "mano latsopano." Kuwonjezera chimango zopangidwa zirconia, mosiyana ndi zitsulo si deform ndi nthawi. Pakuti veneering ceramic ntchito, cholinga mwachindunji cholinga ichi ndi kukhala translucency ofanana.

Anthu ambiri akudziwa mmene choopa kuwononga dzino korona pa chakudya raskusyvanii kwambiri olimba. zirconia adzakhala tichotse nkhawa ili yonse. Ngati pali hairline mng'alu, nkhani akuchira akuphatikizapo yekha pa mlingo maselo.

Pamene a prosthesis mano ngati chitsulo kapena akorona zitsulo-ceramic, mu usinini umatchulidwatchulidwa wakuda bezel. Mano ndi mafupa zirconia, ngakhale ndi ntchito kwa nthawi yaitali, sayambitsa kusintha kulikonse mu usinini.
