Kodi Zirconia Block ndi chiyani?

Monga tonse tikudziwa pali mitundu itatu ya zida zomwe amagwiritsidwira ntchito pakubwezeretsa mano: zirconia block zakuthupi ndi zinthu zachitsulo. Zirconium oxide imapezeka ngati monoclinic, tetragonal ndi cubic crystal mawonekedwe. Magawo okhala ndi sinthana kwambiri amatha kupangidwa ngati kiyubiki ndi / kapena mawonekedwe amtundu wa kristalo. Pofuna kukhazikitsa zolimba za kristalo, zolimbitsa monga magnesium oxide (MgO) kapena yttrium oxide (Y2O3) ziyenera kuwonjezeredwa ku ZrO2.

Chifukwa chiyani zirconia block ndichabwino kwambiri pamano kubwezeretsa?

Tiyeni tikambirane mapangidwe a zirconia. Malo a zirconia amano amapangidwa ndi crystalline oxide mawonekedwe a zirconium, ndipo amakhala ndi atomu wachitsulo mu kristalo koma samawoneka ngati chitsulo. Chifukwa cholimba komanso chosagwirizana, madokotala ochita opaleshoni kapena madokotala amagwiritsa ntchito zirconia zamazinyo m'mazinyama osiyanasiyana. Ngakhale imagwiritsidwa ntchito mu implants chifukwa imadziwika kuti ndi yamphamvu kwambiri.

Ngakhale mankhwala ambiri amagwiritsidwa ntchito m'makampani opanga mano, chipika cha mano cha zirconia chomwe chimadziwikanso kuti ceramic block ndichotchuka kwambiri pakati pa dotolo wamano ndi odwala.

Ubwino wina wamazinyo a zirconia amano:

- Monga amapangira ntchito chitukuko chatekinoloje. Ndi kulimba kwakukulu kwa fracture, kukulitsa kwamatenthedwe kofanana ndi chitsulo chosungunuka, mphamvu yayikulu kwambiri yopindika ndi kulimba kwamphamvu, kukana kwambiri kuvala ndi dzimbiri, kutsika kwamatenthedwe otsika

- Komanso, imavomerezedwa ndi mabungwe adziko lonse. Komanso, zotchinga izi zidayesedwa kuti zikhale zoyera, kuti zitsimikizike kuti ndizotetezeka.

-Dental zirconia block ndi chinthu chapamwamba kwambiri, komanso zimapangitsa kuti dzino likhale lolimba komanso lachilengedwe.

-Chinthucho chikakhazikika mkati mwa wodwala, chimapatsa alumali moyo wabwino.

-Zopindulitsa zina zofunika za chipika ichi cha zirconia chamano ndi chomwe chimachepetsa nthawi yowumitsa chisanachitike ndikuwongolera mawonekedwe owoneka bwino nthawi yakudaya.

-Zinthu zofunikira kwambiri pamtunduwu ndizotheka kukhala ndi mawonekedwe amtundu uliwonse, komanso zimatha kufanana ndi kukula ndi mawonekedwe aliwonse.
