Njengoko sonke siyazi ukuba kukho iintlobo ezintathu zezinto ezisetyenziselwa ukubuyisela amazinyo: i-zirconia block material kunye nentsimbi.IZirconium oxide yenzeka njengemonoclinic, tetragonal kunye necubic crystal forms.Iindawo ezixineneyo zinokuveliswa njenge cubic kunye/okanye iifom zekristale yetetragonal.Ukuze uzinzise ezi zakhiwo ze-crystal, i-stabilizers ezifana ne-magnesium oxide (MgO) okanye i-yttrium oxide (Y2O3) kufuneka yongezwe kwi-ZrO2.
Kutheni ibhloko ye-zirconia iyona mveliso ifanelekileyo kumazinyoukubuyisela?
Makhe sithethe ngokuqulunqwa kwe-zirconia.Ibhloko ye-zirconia yamazinyo yenziwe nge-crystalline oxide form ye-zirconium, kwaye iqulethe i-athomu yensimbi kwi-crystal kodwa ayikaze ithathwe njengesinyithi.Ngenxa yezinto ezihlala ixesha elide kunye ne-biocompatible, oogqirha botyando okanye oogqirha basebenzisa ibhloko ye-zirconia yamazinyo kwiiprostheses ezahlukeneyo.Nditsho nokuba isetyenziswa kwizinto zokufakelwa njengoko ithathwa njengeyona nto inamandla.
Nangona iimveliso ezininzi zisetyenziswa kwishishini lamazinyo, ibhloko ye-zirconia yamazinyo ekwabizwa ngokuba yi-ceramic block idume kakhulu kugqirha wamazinyo kunye nezigulana.
Ezinye izinto eziluncedo kwiibhloko ze-zirconia zamazinyo:
-Njengoko iveliswa kusetyenziswa uphuhliso lobuchwepheshe obuphezulu.Ngokuqina okuphezulu kokuqhekeka, ukwanda kwe-thermal okufana nentsimbi etyhidiweyo, amandla okugoba aphezulu kakhulu kunye namandla okuxinana, ukuxhathisa okuphezulu ukunxitywa kunye nokubola, ukuhanjiswa kwe-thermal ephantsi.
– Kwakhona, kuvunywe ii-arhente zelizwe.Kwakhona, ezi bloko ziye zenza uvavanyo oluthile lokucoceka, ukuqinisekisa ukuba kukhuselekile ngokupheleleyo ukusetyenziswa.
-Ibhloko ye-zirconia yamazinyo yimveliso ekumgangatho ophezulu, kwaye yenza izinyo lomelele ngakumbi kwaye liyindalo.
-Emva kokuba imveliso ifakwe ngaphakathi kwesigulane, iya kunika ubomi obuhle kwi-shelf kwimveliso.
-Ezinye izibonelelo ezibalulekileyo zale block zirconia zamazinyo ziya kunciphisa ixesha lokumisa kwangaphambili kunye nokuphucula imbonakalo ebonakalayo ngexesha lokudaya.
-Ezona mpawu zibalulekileyo zale mveliso kukuba inokuba nako ukuvela kwakhona kombala wendalo, kwaye inokutshatisa nabuphi na ubungakanani kunye nokumila.
