Na oge a na dentistry, nhọrọ nke ihe maka prosthesis sonye na akaụntụ bụghị naanị ya ọrụ, ma aesthetics. Zirconia, nke na-eji maka prosthetics na ọgwụ na ahụ ike na-eme ebe ọ bụ na 1969, na-esiwanye na-eji maka imewe nke eze prostheses. Mgbe ụfọdụ, na-enweghị iji ya kpọmkwem chemical aha, a stof bụ naanị akpọ zirconium. Na dentistry, ọ na-emekarị eji na-eme ozu eze okpueze.

Okpueze nke zirconium dioxide, nwere ikike na-ebunye ìhè, a pụrụ iji tụnyere translucency nke eke ezé, wee na-ele eke na-adịghị dị iche iche si eke ezé. Na nke a ha nwere anwụ ngwa ngwa tụnyere na ike nke metal okpueze.

Ke imewe nke denture isi n'ihi na a okpueze na-emekarị smelted. Okpueze zirconia - ma e wezụga. A laser nyocha kpebisiri ike site na udi nke ga-eme n'ọdịnihu okpueze, na data na-esichara site a omume kọmputa, na a na kọmputa nlereanya aghụghọ nke okpueze.
