He maha nga painga o te zirconia katoa-ceramic porcelain denture

1. Rerehua

He āhua tūturu, he ātaahua hoki te āhua o te whakahokinga mai o ngā niho rūpahu uku-katoa, ā, he rite te tae ki ngā niho tūturu. Ko te mea nui, he pai te mārama me te hurihanga o ngā niho rūpahu uku-katoa, ā, kāore he rārangi pango i te kaki o te niho, kia pai ai te āhua o te kaki o te niho, he mea e kore e taea te eke ki te taumata o ngā niho rūpahu porcelain noa.

2. Paioraora

He tino pai ngā āhuatanga o te zirconia mō ngā mahi hauora me ngā mahi niho e pā ana ki te haumaru koiora. I roto i ngā tau, he maha ngā kēhi whakamātautau me ngā kēhi haumanu kua whakaatu kāore he kino paitini o te zirconia ki ngā pūtau wheua me ngā kiko ngohengohe, ā, kāore he pūrongo mō ngā tauhohenga mate pāwera.

3. Te Kaha me te Matotoru

(1) Ko ngā uku zirconia he uku zirconia kua whakapūmautia ki te yttrium, he kaha piko teitei. I tēnei wā, kua eke te kaha o ngā rauemi kua rēhitatia ki Haina ki te 900MPa, ko te paerewa ā-motu mō ngā rauemi niho he 100MPa.

(2) Ki te whakaritea ki ētahi atu rauemi whakaora uku katoa, mā te kaha o te rauemi zirconia ka taea e ngā tākuta te whakatutuki i te kaha tino teitei me te kore e huri nui i ngā niho tūturu o te tūroro. I roto i ēnei, ko te Vita all-ceramic plus-yttrium me te plus-stabilized oxide Zirconia e mōhiotia ana ko te maitai uku.

4. Whakamaapene

Ka oti te whakaputa mā te hoahoa ā-rorohiko, te matawai taiaho, me te huri ā-rorohiko. Ka whakamanahia te tika o te whakapiringa i hangaia me te piri pai o ngā taha, ka pai te uru o te niho porcelain ki te abutment i roto i te waha o te tūroro.

5. He iti te kaha o te irahiko

He tino pakari ngā paerewa a te Tari Kai me te Rongoā a te Kāwanatanga mō ngā rauemi uku katoa kei te mākete, ā, ka taea anake te whakamahi hei rauemi hauora i muri i te tutuki i ngā whakaritenga o ngā whakamātautau hihi-ā-ira. Ehara i te mea ko te zirconia anake ngā whakaritenga, engari ko te porcelain whakapaipai, te alumina, ngā uku karāhe, me ētahi atu. E whakaatu ana ngā whakamātautau ko te kaha o te hihi-ā-ira o te paura zirconia parakore ehara i te mea he iti iho i te uku karāhe, engari he iti iho hoki i te kiko wheua tangata.
