Kodi Zirconia Block ndi chiyani?

Monga tonse tikudziwa kuti pali mitundu itatu ya zida zomwe zimagwiritsidwa ntchito pobwezeretsa mano: zirconia block zakuthupi ndi zitsulo.Zirconium oxide imapezeka ngati mawonekedwe a monoclinic, tetragonal ndi cubic crystal.Zigawo zokhala ndi sintered zimatha kupangidwa ngati ma kiyubiki ndi/kapena ma tetragonal crystal.Kuti akhazikitse zida za crystal izi, zokhazikika monga magnesium oxide (MgO) kapena yttrium oxide (Y2O3) ziyenera kuwonjezeredwa ku ZrO2.

Chifukwa chiyani zirconia block ndiye chinthu choyenera kwambiri pamanokubwezeretsa?

Tiyeni tikambirane kupanga mapangidwe zirconia.Dongosolo la zirconia la mano limapangidwa ndi mawonekedwe a crystalline oxide a zirconium, ndipo imakhala ndi atomu yachitsulo mu kristalo koma samatengedwa ngati chitsulo.Chifukwa cha mphamvu zake zolimba komanso zogwirizana ndi biocompatible, madokotala ochita opaleshoni kapena madokotala amagwiritsa ntchito chipika cha zirconia cha mano m'mapangidwe osiyanasiyana.Ngakhale amagwiritsidwa ntchito mu implants chifukwa amaonedwa kuti ndi chinthu champhamvu kwambiri.

Ngakhale mankhwala ambiri amagwiritsidwa ntchito m'makampani a mano, chipika cha zirconia cha mano chomwe chimatchedwanso kuti ceramic block ndichodziwika kwambiri pakati pa madokotala ndi odwala.

Ubwino wina wa midadada ya zirconia ya mano:

- Monga momwe amapangidwira pogwiritsa ntchito chitukuko chapamwamba.Ndi kulimba kwapang'onopang'ono, kukula kwamafuta kofanana ndi chitsulo choponyedwa, mphamvu yopindika kwambiri komanso mphamvu yolimba, kukana kuvala ndi dzimbiri, kutsika kwamafuta.

- Komanso, amavomerezedwa ndi mabungwe a dziko.Komanso, midadada iyi yayesedwapo kuyera, kuwonetsetsa kuti ndiyotetezeka kwathunthu kugwiritsa ntchito.

-Dental zirconia block ndi chinthu chapamwamba kwambiri, komanso imapangitsa dzino kukhala lolimba komanso lachilengedwe.

-Chinthucho chikayikidwa mkati mwa wodwalayo, chimapereka moyo wabwino wa alumali kwa mankhwalawa.

-Mapindu ena ofunikira a chipika cha zirconia cha mano awa chidzachepetsa nthawi yowuma chisanadze ndikuwongolera mawonekedwe owoneka panthawi yopaka utoto.

-Zomwe zimafunikira kwambiri pamtunduwu ndikuti zimatha kukhala ndi mawonekedwe amtundu uliwonse, komanso zimatha kufanana ndi kukula ndi mawonekedwe aliwonse.
