Zirconia

karauna Metal-uku e whakamahia i roto i te mahi niho mo te wa roa, me te tino pai. He roa ratou, engari kia whiwhi ai ratou i te tahi mau drawbacks i roto i ngā o te ahua. hanga pānga niho ora te wāhanga anake, kia rite ki te mea kahore āta tīpako tae okouku. Tenei Ko te mea te anga whakarewa he ona ake tae, kanohi ki tonu i kore e e mahi tonu. Ko tētahi atu ngoikoretanga o enei prostheses - pānga maitai kino i runga i te pae. e kore e karauna uku i enei drawbacks, engari e kore e tata rite kaha rite te karauna ki ratou he anga whakarewa.

I roto i te niho hou, tangohia te kōwhiringa o ngā rauemi mo te prosthesis ki pūkete tona taumahinga kore anake, engari ano hoki rerehua. Zirconia, Kei te whakamahia e hoki prosthetics i roto i te mahi hauora mai 1969, kei te piki te whakamahia mo te hanga o prostheses niho. I te tahi taime, i waho te whakamahi i tona ingoa matū tangohia, kua karangatia e noa tenei mea zirconium. I roto i te niho, kei te nuinga o whakamahia ai mō te hanga i te tinana karauna niho.

Karauna o zirconium hāorarua, i te kaha ki te tuku te marama, i rite nei ki te translucency o niho tūturu, na titiro tūturu me he kahore rerekē i niho taiao. I roto i tenei take to ratou mauroa rite ki te kaha o karauna whakarewa.

I roto i te hanga o te turanga denture mo te karauna te tikanga te kamaka. zirconia Karauna - okotahi. whakaritea te matawai taiaho e te āhua o te karauna i mua nei, tukatuka te raraunga e te hōtaka rorohiko, me te tauira rorohiko whakaaro o te karauna. Na he taputapu motuhake, kia rite ki te hōtaka rorohiko tomu'a mahi ana tapahi atu i te wahi kotahi o te zirconia. Te karauna hua kua kore anake pū nui, engari āta whakarite hoki ahua tino.

More tata, kua anake tāuta te karauna o te rauemi uku i runga i te niho mua, e ko, ko e tika ratou whakamahi, kaua, take rerehua atu i tono mahi. e kore fakangatangata Mā te zirconia. Ko reira e tika ana mō te mārōrō prosthetic me niho posterior, ka nunumi maitai ki te implants. Mā te tenei hangarau, hangaia karauna kotahi, me te atu piriti. Zirconia - taea reira te whakamahi hypoallergenic me tino bioinert i roto i te pā ana ki te rauemi tinana tangata mō prosthetics noa e pängia ana ki te mate pāwera o tūroro. E ai ki te tohu Bioinert taea reira ara koura.

He Zirconia he āhuatanga mātao waiariki tiketike, na tiaki karauna niho i pāmahana tino. Ko te painga hoki te hunga tūroro e tairongo ki te kai wera, me te matao nei niho tenei.

Ko te tino kikokore tinana karauna, tona matotoru, ko te 0.4 anake mm. Na reira, ko te otinga, o te hanganga denture whakarato ma'unimaá tata inamata "niho hou." Haunga anga i hanga o zirconia, e kore e maitai pērā deform ki te wā. Hoki whakamahia paparua uku te, hangaia mō tenei whakaaro me te whai rite translucency.

e mohio ana tokomaha te iwi te mana'o o te wehi o hoko te karauna niho i te kai mārō rawa raskusyvanii. ka whiwhi zirconia whakakahoretia o tenei manukanuka katoa. Ki te reira te mea he kapiti hairline, ora te rauemi tona hanganga anake i te taumata rāpoi.

A, no te te prosthesis niho maha puta rite te whakarewa karauna whakarewa-uku ranei, i roto i nga pae bezel mangu. Niho ki zirconia kōhiwi, ara ki te whakamahi roa, e kore e meinga tetahi huringa i roto i te pae.
