Zirconium okusayidi: katundu, contraindications makamaka ntchito mano

Zirconium okusayidi kale kwambiri ntchito mano, ndipo amakhala ndi durability ake ndipo ngakhale ndi chilengedwe. Zonsezi zikutsimikiziridwa ndi maphunziro ambiri matenda.

Ubwino mitembo

okusayidi zirconium ntchito kulenga anakonza komanso, makamaka frameworks ofotokoza ndi zinakwaniritsidwa ndendende. Zonsezi zimachitika ndi ntchito zamakono zachipatala. Zamgululi nkhani imeneyi ndi cholimba, zikuoneka palibe wina kusiyanitsa ndi mankhwala kupanga mano zachilengedwe.

okusayidi zirconium wodzaza ndi dongo misa wapadera, amene ali chiyambi achilengedwe. Zonsezi zimapangitsa mankhwala wangwiro, poyerekeza ochiritsira nyumba zitsulo-ceramic ntchito mano.

Tab zirconium okusayidi, veneers ndi milatho - ndi ofunika kwambiri chifukwa cha nkhani cholimba ndi biocompatible.

A chimango akadali pa maziko a nkhaniyi angathe kuchepetsa khoma makulidwe zachifumu, motero, kuya kwa minofu Machining molimba mano amadziwikanso yafupika. Chifukwa cha thandizo ili pakamwa angapulumuke, ndi prosthesis kukhala kosavuta.

NKHANI zonse ceramic

Zirconium okusayidi ntchito Pangani akorona, kumene zotayidwa anawonjezera. Iwo akutchedwanso zitsulo-free. Mu yopanga lero ndi zofala ndi yodziwika ndi mphamvu zawo mkulu. Mbali yaikulu - kusapezeka kwa zigawo zitsulo ndi mkulu zokongoletsa kamangidwe.

Zitsulo-free korona pa zirconia ndi aluminiyamu chifukwa cha kumayambiriro zamakono mkulu mano. Sizoti ndi cholimba, biocompatible ndi mano, komanso kuunika mandala. Kunja, palibe wina adzaganiza kuti uli ndi korona, kotero izo zikuwoneka achilengedwe.

Pangani sanali zitsulo akorona

zoumbaumba amenewa ankagwiritsa ntchito yopanga korona osati lonse, komanso inlays ndi veneers. Ngati inu kale anaika zisindikizo zinada kapena wokalamba korona osintha mtundu, zirconium okusayidi, lomwe lili ake pachimake, kungatithandize kuti Mokweza.

Mu kupanga dokotala nyama amachotsa osewera a dentition mtima wake, kenako ofotokoza anapanga sera chitsanzo. Iwo scanned ndi kompyuta, ndiye kuti akonze mawonekedwe atatu azithunzi omwe tikunena ndi cholinga kukumana shrinkage m'tsogolo. Ndiye chimango aikidwa mu chipangizo wapadera mphero kumene milled zirconium okusayidi.

Kenaka sintered panagona ng'anjo, kupeza mphamvu. Ndipo potsiriza, chimango ndi wodzaza ndi misa ceramic. Chifukwa analandira biocompatible akorona m'mano, zirconium okusayidi mu khalidwe limeneli ndi lofunika.

Potsanzira

Ziwalo za okusayidi zirconium nthawi zambiri akutsutsana adazindikira mwa thupi la munthu. Iwo cholimba ndi odalirika, palibe chiopsezo kukanidwa ndi matenda.

Potsanzira zachilengedwe mano zimatheka chifukwa chakuti okusayidi zirconium pawiri ali azioneka woyera. Pamene khazikitsa ndi zitsulo-ceramic korona ngati sangathe kuwapeza chifukwa ili ndi mamangidwe a chimango adzakhala mtundu zachitsulo. A chitsulo ceramic sangosonyeza kudzera, nduwira zokuzira ndi ❖ kuyanika wapadera. Chifukwa, ziwalo zimenezi kachilombo kuwala, ndi kuzama mtundu alibe. M'kamwa osati kuunikiridwa ku mkati, monga mawonekedwe a chirengedwe, ndi kukhalapo kwa thupi zakunja pakamwa adzadziwika.

The ntchito mode basi opanga

Korona kwambiri kuti zitsulo-free yopangidwa ndi luso lapadera, lomwe ndi chosiyana kuchokera mankhwala dzanja zopangidwa ndi zitsulo zosungunula. njira onse ikuchitika mode basi.

Kulolerana kusiyana pakati pa prosthesis ndi dzino okha sizingapereke osiyanasiyana monga microns 100 mpaka 300. Kudzera luso lamakono, ntchito kupanga zinthu zopangidwa zirconia, izo kusanduka 30 microns. Izi zikutanthauza mwatsatanetsatane pazipita mu mafupa pakati pa mano ndi prosthesis.

kupanga milatho

Ngakhale ngati maonekedwe enieni prosthesis akhoza chopangidwa popanda dongosolo zitsulo. Bridge wa okusayidi zirconium akhoza kuthamanga, koma iye sangakhoze kukhala kutalika lalikulu, mwachizolowezi. chimango wake mosiyana ndi zitsulo, adzakhala chimaonekera.

Komanso, zirconium okusayidi angagwiritsidwe ntchito pa prosthesis pa amadzala, ngati wodwala akusowa mkulu mlingo wa aesthetics. Ndipo, monga tanenera poyamba, mwina ntchito kupanga mtundu uliwonse wa prosthesis.

kunja

Mmodzi mwa ubwino chifungulo cha akorona zochokera okusayidi zirconium ndi maonekedwe zachilengedwe ndi pempho. Ngati zitsulo-ceramic anaukitsidwa nthawi zonse chosiyana hue, mu nkhani iyi n'zotheka kukatenga pa mlingo chimango kuti athe yesezera mtundu wa mano wodwalayo. Kaya mtundu wa kuunikira, dzino adzatsala mandala. Komanso, mosiyana ndi zitsulo, zomwe ndi nthawi amakonda mdima ndi kukhala opunduka, zirconium okusayidi, ngakhale kwa zaka zambiri ali yemweyo.

Komanso, ambiri Kawirikawiri za kusintha kwa mtundu wa m'kamwa pafupi ndi akorona zitsulo-ceramic. Izi zimachitika chifukwa chakuti kamangidwe ka chimango ali kungasokoneze minofu moyandikana ndi izo. Inde, m'kamwa redden kapena kukhala cyanosis si nthawi zonse, koma nthawi zokwanira. Ziwalo ndi zirconia kwathunthu kuthetsa zodabwitsazi.

ngakhale

Zirconium okusayidi ndi zabwino chifukwa ali ndi katundu hypoallergenic. Pamaso nkhaniyi anamugwiritsa ntchito mano, amagwiritsidwa ntchito kawirikawiri mu kupanga mitu kwa m'chiuno ziwalo kusintha mphamvu zawo.

mawonetseredwe awo sagwirizana odwala pa unsembe mano yokumba kapena totsegulira ambiri zimachitika kawirikawiri zokwanira. Komanso, motero akhoza wasonyeza ngakhale pamene ntchito wolemekezeka mitundu zitsulo (golide, pulatinamu, palladium, ndi ena). Korona kapena zirconium okusayidi milatho anthu ambiri akudwala chifuwa ndi zotheka njira yokhayo kuti abwere mano.

vuto la dzino tilinazo ndi zambiri. Pa chodabwitsa apulasitiki zingathandize kukhazikitsa zonse muyenera. Choncho, pamene inu kwabasi akorona popanda zitsulo pakhomo zimasiyanasiyana kwambiri kwa bwino. Zonsezi ndi chifukwa chakuti okusayidi zirconium ndi kwambiri zachilengedwe insulator ndipo akhoza kuteteza mano ku monyanyira zizindikiro kutentha. Ngati ofotokoza kubala copings, mtima sadzakhala poyera kuti kukondoweza matenthedwe.

ubwino zina

Zirconium okusayidi pang'ono apindula ndi aluminium ndi okhazikika chifukwa yttrium, amene kenako zimapangitsa mankhwala ake pa maziko amphamvu ndi kuwala. Komanso, maonekedwe a microcracks pamwamba, pamwamba dongosolo limabwezeretsa lokha pa mlingo wa mamolekyulu.

Korona anapangidwa ndi zirconium, osati pa mano kutsogolo, komanso pambali.

nkhaniyi, mwa zina, akuti ndi yabwino kwambiri kukonza kutalika kwa kuluma. Iye alibe porosity, mosiyana zoumbaumba zitsulo, kotero kumva kuwawa muzikangana ndi mitengo m'munsi.

Popeza kuti Korona anatomical akhoza kutaya mphero, zimathandiza akatswiri apadera bwinobwino kuwatsatira pa prosthesis ndi Tinthu kauntala akugwira kutalika kwa kuluma.

Processing molimba mano minofu pamene anaika onse-ceramic prosthesis ndi kochepa. Chimango kwa okusayidi mano zirconium ali ndi makulidwe a 0.4 millimeters. Zimenezi zimathandiza osachepera pogaya iwo ngakhale kupanga prosthesis moyo.

Kuipa ndi contraindications

Mofanana ndi mankhwala ena aliwonse ntchito mu zolinga za mano zochokera zirconium okusayidi ziwalo ndi contraindications awo. Ngakhale kuti pali awiri okha wa iwo, sanalembedwepo zambiri:

• bruxism;
• kutchulidwa overbite.

Nthawi zina mukhoza kuika nkhata, ngakhale wodwalayo kumabweretsa kalata ya kukhalapo pa chifuwa ndi zigawo zina za ziwalo. Pakuti onse ceramic-silidzachotsedwa ankachitira.

Koma kuipa mankhwala zochokera okusayidi zirconium, iwo kwenikweni ali. Komabe, chinsinsi ndi imodzi yokha - ndi mtengo awo okwezeka. mtengo uwu aumbike osati mwa ntchito zigawo zina, komanso kuchulukitsa kwa kupanga zachifumu. Apa, katswiri ayenera kukhala mkulu mlingo wa luso ndi kuphunzitsidwa njira yapadera pa mlingo mkulu.

Ngati wodwala alibe ndalama mankhwala mtengo zochokera okusayidi zirconium, ukakhala ndi kupereka buku la bajeti pamaziko a galasi processing. Korona, amene okhazikika ndi okusayidi yttrium, ndi zambiri zodula.

Monga mukuonera, zikuchitika masiku ano m'munda wa mano akhoza kwambiri patsogolo miyoyo ya anthu amene amafunika kupeza mano otere ndi kusuntha zawo zoipa.
