Ko nga mea puaa mo te Piriti Niho

Ngā momo piriti niho

Ka honoa e te piriti niho ngā āputa i waenganui i ngā niho mā te whakamahi i ngā karauna, i ngā parirau rānei hei pupuri i te piriti kia mau tonu. E toru ngā momo piriti niho:

Piriti Tuku Iho: Ko te piriti e whakamahia whānuitia ana, ko te piriti tuku iho he karauna e rua, tae atu ki te toru piriti. Ka piri te karauna ki ngā niho hauora e rua i ia taha o te āputa e iri ana te piriti.

Piriti Cantilever: Kotahi anake te karauna kei roto i tēnei kōwhiringa, ā, tae atu ki te toru ngā piriti. He mea tika ngā piriti cantilever mēnā kua whai karauna ngā niho tata, kotahi anake te niho o te tūroro i te taha o te niho ngaro, mēnā rānei he tino pai ki te titiro.

Ngā piriti e tautokona ana e te whakatō: Engari ko ngā niho hauora hei tautoko i te piriti, ka mau tonu i ngā whakatō. Koinei te kōwhiringa piriti niho tino pakari, tino roa hoki te mau.

Ngā painga o te piriti niho

Anei ngā painga o te whiriwhiri i tētahi piriti i runga i ngā niho rūpahu, i ngā mea tāpiri rānei:

Kāore e hiahiatia he pokanga mō ngā piriti niho. Ki te kore he piriti tautokona e te whakatō, kāore koe e hiahia ki te pokanga hei whakaora i tō ataata. He tere, he ngāwari hoki ngā piriti tuku iho, ngā piriti cantilever, me ngā piriti Maryland, ka taea te mahi i te wā kotahi, ā, kāore e hiahiatia he whakaora roa.

He iti ake te utu mō ngā piriti niho i ngā tāpiringa niho. Ko te tahua te mea e whakaarohia ana e te nuinga o te tangata ina tae mai ki te whakahounga niho. He iti ake te utu mō ngā piriti nā te mea kāore e hiahiatia he pokanga, he rite rānei te tika ki ngā tāpiringa niho.

He haumaru ake ngā piriti niho i ngā niho rūpahu. He maha ngā amuamu a ngā tūroro whai niho rūpahu mō te nekeneke, te taka rānei o ā rātou niho rūpahu i a rātou e kai ana, e kōrero ana rānei. Ka piri ngā piriti ki ētahi atu niho, ki ngā mea tāpiri rānei, ehara i te kapia.

He āhua tūturu ake ngā piriti i ngā niho rūpahu. Waihoki, he maha ngā wā ka neke ngā niho rūpahu i roto i te waha, he mea e kore e pai ki te tūroro engari ka kitea e te hunga e karapoti ana i a rātou. He rite tonu te āhua me te āhua o ngā piriti niho ki ngā niho tūturu, nō reira kāore rawa tetahi e mōhio ehara i te mea tūturu!

• Te Kaha me te Mātotorutanga:

(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.

Ehara i te mea ko te zirconia anake ngā whakaritenga, engari ko te porcelain whakapaipai, te alumina, ngā uku karāhe, me ētahi atu.
