Akatswiri a ma prosthetics kwa zaka zambiri anali kufunafuna zipangizo zothandiza kwambiri zomwe zingakhale ndi mphamvu zofunikira ndipo zikanakhala zotetezeka kwa anthu. Zirconium korona ndi zinthu zatsopano, zomwe zimapezeka ku zirconium dioxide, zomwe zimakhazikitsidwa bwino ndipo zimalola kuti pakhale ma prostheses alionse ovuta.
Zirconia korona wa mano
Poyerekeza ndi zipangizo zina, zirconium ikhoza kutchedwa kuti chilengedwe chonse. Ndi chithandizo chake, mutha kukwaniritsa mthunzi wolondola wa mapangidwe, pafupi ndi momwe mungathere ndi mtundu wa mano achilengedwe. Iwo amadziwika bwino ndikutumikira kwa nthawi yaitali, popanda kukhumudwitsa.
Kuwonjezera pamenepo, ziyenera kuzindikiranso ubwino wa zirconium korona.
Kuphatikizana kwathunthu kwa prosthesis, chifukwa chakuti nkhaniyo siili bwino, popanda kukhumudwitsa zovuta.
Mphamvu zapamwamba, kulola kuyika korona ya zirconium pa kuyika kapena pa dzino.
Luso lamakina laserer limakuthandizani kupanga korona yaing'ono kwambiri ndikulondola kwambiri, kotero simusowa kulimbitsa dzino, lomwe limakhudza kwambiri vuto lake m'tsogolomu.
Kwa nthawi yaitali, korona imapitirizabe kugwira ntchito komanso yokongola.
Zirconia korona pa mano am'tsogolo
Chinthu chofunika kwa ma prosthetics a mano opatsirana ndi ntchito yokhayo yokhayokha komanso yogwiritsidwa ntchito.
Ma prosteses amaloledwa mmalo mwa mano owonongeka kapena osokonezeka kapena, ngati sakupezeka ndi implants. Mwachiwonetsero chake, zirconia ndi pafupi kwambiri ndi dzino lachitsulo. Dokotala amasankha mthunzi payekha kwa aliyense kasitomala. Chifukwa cha kupirira kwapamwamba komanso nthawi yothandizira, musadandaule kuti pamapeto pake mapangidwewo adzachotsedwa kapena kukhala osasintha.
Zirconium korona za mano a kutafuna
Ubwino wa zirconium dioxide umaloledwa kuzigwiritsira ntchito poika mano. Chifukwa cha kukwanira kwa zomangamanga kwa chingamu, kuthekera kwa chiwonongekocho kulipo ndipo kusakaniza chakudya kumaletsedwa. Izi zimachepetsa chiopsezo cha caries.
Kuzindikiranso ndi kusowa kofunikira kuchotsa mitsempha, ndipo chinthu chodziletsa chingalephere kupanga mapangidwe a mano pambali pa prosthesis.
Metal-ceramic korona kapena zirconium?
Chosavuta chachikulu cha zirconia ndizofunika mtengo wake. Ndicho chimene chimapangitsa odwala ambiri kuti azikonda zinthu zopanda mtengo.
Zitsulo zotchedwa Metal ceramics ndizofanana ndi mthunzi wa chilengedwe, koma sizimveka bwino.
Zirconia dzino zisoti ndi hypoallergenic, mosiyana ndi zitsulo. Chifukwa cha kugwirana kwake, zinthuzo sizochepa ngakhale ku golide.
Chifukwa cha kuchuluka kwa ma prostheses a zirconium, palibe kufunika kofunika, zomwe sizili choncho ndi cermets.
Pang'onopang'ono, nyumba zowonjezera zimatembenuza buluu kumbali, zomwe zimawoneka makamaka pamene munthu akumwetulira.
Kukonzekera kwa makompyuta ndi njira zowonetsera zimapangitsa kuti zitheke kupeĊµa zolakwika zilizonse ndi kukwaniritsa molondola. Izi zimapangitsa kuti munthu asamamvetsetse bwino komanso kupewa kutupa, zomwe sitingathe kuzipeza pogwiritsa ntchito malemba.
Moyo wautumiki wa korona wa zirconium ndi zaka 15, pamene iwo akusunga maonekedwe awo oyambirira. Zida zamakeramic zimatha pafupifupi zaka 10.
Kupitilira kuchokera pamwambapa, zikhoza kuzindikirika kuti khalidwe lapamwamba ndikhalitsa limapindulitsa mokwanira mtengo wa ma prostheses. Choncho madokotala amalimbikitsa kugwiritsa ntchito zirconium.
