Rauemi whakakī niho

Te tākuta he kōwhiringa nui o ngā rauemi mō te taatiraa, whakaaro rawa rerekē. Taua kanorau homai ia i te whai wāhi ki te tīpako i te kōwhiringa e tika ana ake mo te manawanui ngā. Ko te whakahaere e tefito'i mo'oni o whakakī rauemi Are pūmau me rangitahi.

I roto i aua wā, ina te hiahiatia reira ki whakahoki te āhua niho whakamahia whakakī rauemi taimau. kia riro ratou i te mau huru e whai ake nei: ki te whai resistance ki te ahotea aunoa (hei tauira, ki ngaungau mahi), ki te mahi o te huware me he inu e tu i roto o te pūnaha kūnatu, ki te whai plasticity me kore e huri mo te wa roa, rōrahi me te āhua e kore e taua pānga pēhia i runga i te ngohengohe te kopa o te kōhao-waha, tomo noa ki te ruma sealable i wahi o te hanganga o caries niho, riro adhesion pai ki te niho matūniho me te tae e ōrite ana ki te tae o niho māori. no Compomers, composites, tima, amalgams, kirihou ki te rauemi whakakī tūturu.

He rite ki te slurry i roto i te take organic composites, kua he pokey o te hanganga o matū pararopi, hoatu reira nga āhuatanga e tika ana. Composites me ngā rauemi whakakī mō awa pakiaka wehea ki haapuai e te tauhohenga matū motuhake ranei kōnakonako. Composites - manawarau i roto i te mahi i te rauemi ki te mahi ki a he tika wheako ki te whai whakangungu motuhake.

excipient Composite ahei riro āhuatanga rerekē o te matūriki, e hanga ana e ia taea ki te wehe i te reira ki ngā akomanga rātou:

- makrofily ki matūriki filler o te rahi nui homai te kaha hiato o te uara nui, engari paku whakaiti ratou taonga o adhesion ki te mata o te kiko;

- taonga ataahua oro, engari iti kaha mikrofily rerekē ki kore e nga matūriki filler rahi rawa nui - whakamahia ki whakaturia te hiri ki runga ki nga niho mua waenganui;

- Hybrids Ko te huinga o matūriki o karaihe konu rahi nui me matūriki silicon iti, he rite i roto i o ratou āhuatanga ki te kopa niho pakeke ratou, i roto i ētahi wā e whakamahia ana ki te whakaturia te hiri rite tika ana mo nga whakaritenga katoa ki rauemi mō te taatiraa.

rauemi angitu atu niho whakakī - compomers whakakotahi hiato kākano kounga ki ionomer karaihe sima. E ratou he adhesion pakari ki te kopa niho pakeke, biocompatibility pai ki te kopa tinana taea ki te aro köwhai, he, kua pai ake ngā āhuatanga rerehua pērā i mārama me te tae, reira, e tika ana mō te taatiraa i tetahi niho.

paninga Amalgam - pani te koranu mēkuri ki te hiriwa ranei te tahi atu konganuku motuhake rerekē uara nui haere te kaha, me te tika, kōngohe, ātete ki whākōkī o te pūnaha kūnatu, āhuatanga āhuatanga bactericidal (whakamate huakita) ki reira.
