Yintoni umahluko phakathi kweebhloko zeglasi-ceramic ezifakwe ikristale kunye neebhloko zeglasi-ceramic ezifakwe ikristale ngokupheleleyo?
Iibhloko ezenziwe ngekristali zithambile kwaye kulula ukuzigaya, kodwa zifuna ukugaywa ngekristali emva kokugaywa. Iibhloko ezenziwe ngekristali ngokupheleleyo sele zikwimeko yazo yokugqibela kwaye zinokugqitywa ngaphandle kokugaywa, kodwa zinzima kakhulu kwizixhobo nakumatshini.
Ngaba iiglasi-ceramics zingagaywa ecaleni kwesitulo?
Ewe. Iibhloko zeglasi-ceramic zenzelwe i-CAD/CAM, kwaye oomatshini bokugaya abamanzi abancinci benza ukuba kube lula ukuphinda kulungiswe izinto ezinje ngee-inlays, ii-onlays, ii-veneers kunye nee-crowns kwindawo yeklinikhi.
