Iyini i-Zirconia Block?

Njengoba sonke sazi ukuthi kunezinhlobo ezintathu zezinto ezisetshenziselwa ukubuyisela amazinyo: i-zirconia block material kanye nensimbi.I-Zirconium oxide yenzeka njenge-monoclinic, i-tetragonal kanye ne-cubic crystal amafomu.Izingxenye eziminyene zingenziwa njenge-cubic kanye/noma amafomu ekristalu e-tetragonal.Ukuze kuzinziswe lezi zakhiwo zekristalu, iziqinisi ezifana ne-magnesium oxide (MgO) noma i-yttrium oxide (Y2O3) zidinga ukungezwa ku-ZrO2.

Kungani i-zirconia block ingumkhiqizo ofaneleka kakhulu kumazinyoukubuyiselwa?

Ake sikhulume ngokwakhiwa kwe-zirconia.I-zirconia block yamazinyo yenziwe ngohlobo lwe-crystalline oxide ye-zirconium, futhi iqukethe i-athomu yensimbi ku-crystal kodwa ayilokothi ithathwe njengensimbi.Ngenxa yezindawo zayo ezihlala isikhathi eside futhi ezihambisana ne-biocompatible, odokotela abahlinzayo noma odokotela basebenzisa i-zirconia block yamazinyo kuma-prostheses ahlukahlukene.Ngisho isetshenziswa ekufakweni njengoba ithathwa njengento eqinile kakhulu.

Ngisho noma imikhiqizo eminingi isetshenziswa embonini yamazinyo, ibhulokhi ye-zirconia yamazinyo ebizwa nangokuthi i-ceramic block idume kakhulu phakathi kodokotela wamazinyo neziguli.

Ezinye izinzuzo zamabhulokhi we-zirconia wamazinyo:

- Njengoba ikhiqizwa kusetshenziswa ukuthuthukiswa kobuchwepheshe obuphezulu.Ngokuqina kokuphuka okuphakeme, ukunwebeka okushisayo okufana nensimbi ekhonjiwe, amandla okugoba aphezulu kakhulu namandla aqinile, ukumelana okuphezulu nokuguga kanye nokugqwala, ukuguquguquka okuphansi kwe-thermal.

– Futhi, kugunyazwe ama-ejensi kazwelonke.Futhi, la mabhuloki ahlolwe ukuhlanzeka, ukuze kuqinisekiswe ukuthi aphephe ngokuphelele ukusetshenziswa.

-Ibhulokhi ye-zirconia yamazinyo ingumkhiqizo wekhwalithi ephezulu, futhi yenza izinyo liqine futhi libe ngokwemvelo.

-Uma umkhiqizo usufakwe ngaphakathi kwesiguli, uzonikeza impilo enhle yeshelufu emkhiqizweni.

-Izinye izinzuzo ezibalulekile zalesi block zirconia zamazinyo zizonciphisa isikhathi sangaphambi kokumisa futhi zithuthukise umbono obonakalayo ngesikhathi sokudaya.

-Izici ezibaluleke kakhulu zalo mkhiqizo ukuthi ungaba nanoma yimuphi umbala wemvelo ukuvela kabusha, futhi ungafanisa nanoma yimuphi usayizi nokuma.
