Nui nā pono o ka zirconia all-ceramic porcelain denture

1. Nā mea nani

All-ceramic denture hoʻihoʻi i ka realistic a nani helehelena, a ua like ke kala me nā niho maoli. ʻO ka mea nui loa kēlā Loaʻa ka translucency maikaʻi a me ka refraction o nā niho seramika a pau, a ʻaʻole laina ʻeleʻele ma ka ʻāʻī o ka niho, i hiki ai i ka ʻāʻī o ka niho e hoʻokō i kahi hopena aesthetic maikaʻi, ʻaʻole hiki ke hopu me ka maʻamau niho porcelain.

2. Biocompatibility

ʻO Zirconia no nā lāʻau lapaʻau a me nā noi niho he mau waiwai maikaʻi loa i ʻōlelo o ka biosafety. I loko o nā makahiki, nui ka nui o ka hoʻokolohua a me ke kauka ua hōʻike nā hihia i ka zirconia ʻaʻohe mea ʻawaʻawa i ka iwi a me ka ʻiʻo palupalu nā pūnaewele, a ʻaʻohe hōʻike o nā hopena maʻi.

3. Ka ikaika kiʻekiʻe a me ka nui

(1) Zirconia ceramics he yttrium-stabilized zirconia ceramics me ke kiʻekiʻe ikaika flexural. I kēia manawa, loaʻa ka ikaika o nā mea i hoʻopaʻa ʻia ma Kina a hiki i 900MPa, aʻo ke kūlana aupuni no nā mea niho he 100MPa.

(2) Hoʻohālikelike ʻia me nā mea hoʻihoʻi a pau-ceramic, ka ikaika o zirconia mea hiki i nā kauka ke hoʻokō i ka ikaika kiʻekiʻe loa me ka ʻole ka wili ʻana i nā niho maoli o ka mea maʻi. I waena o lākou, ʻo Vita all-ceramic ʻike pū ʻia ʻo zirconia ʻoi aku ka hoʻohui-yttrium a me ka oxide hoʻopaʻa ʻia ma ke ʻano he keramika kila.

4. kōkuhi

Hoʻokō ʻia ka hana ma o ka hoʻolālā kōkua kamepiula, ka nānā ʻana i ka laser, a wili ʻana i hoʻonohonoho ʻia i ka lolouila. Hōʻoiaʻiʻo ia i ka pololei o ka hoʻopili ʻana a me ka paʻa ʻana o ka lihi maikaʻi, e hoʻopili pono i ka niho porcelain me ka abutment ma ka waha o ka mea maʻi.

5. Haʻahaʻa radioactivity

Loaʻa nā kūlana koʻikoʻi o nā kūlana o ka State Food and Drug Administration no nā mea seramika a pau ma ka mākeke, a hiki ke hoʻohana ʻia ma ke ʻano he lāʻau lapaʻau nā mea ma hope o ka hoʻokō ʻana i nā koi o nā hoʻokolohua radiological. ʻAʻole wale Aia nā koi no ka zirconia, akā no ka porcelain decorative, alumina, aniani seramika, etc. Hōʻike nā hoʻokolohua i ka radioactivity o maemae zirconia ʻAʻole haʻahaʻa wale ka pauka ma mua o nā seramika aniani, akā haʻahaʻa hoʻi ma mua o kēlā o ka iwi iwi kanaka.
