He aha e whakakī? Ngā momo o whakakī i roto i te niho

Ehara i tūroro katoa e tono i te whare hauora niho e pā ana ki te mea he rauemi mō te tu niho. Ko tenei take he pānga hāngai i runga i pehea te roa ka pupuri ai i te hiri. I tua atu, i te momo o te rauemi tei runga i te hauora o te niho tona taumata o whīwhiwhi o te tukanga o te maimoatanga me te. I teie mahana paraparau tatou no te ki te whiriwhiri i te rauemi mo nga whakakī. Ngā momo o kekeno, kua kōrero hoki ratou huapai me ngā huakore i roto i tenei tuhinga.

whakaritenga General mō whakakī niho

Tuatahi whakatau te mea rite kei te whakakī i te niho? Ko tēnei rauemi hauora, ai te pokey me plasticity, i roto i te wa e tika ana ki āhuatanga o waho ranei solidifies i te kōhao niho.

He he he rārangi o ngā whakaritenga ki ngā momo katoa o hiri:

1. Haumarutanga. Ka hāngai te rauemi ki te tikanga mā whakapumautia.
2. Insolubility.
3. e kore e murua te hiri holomui i roto i te rōrahi ranei - vilitakí.
4. Kia tā i roto i te wa poto.
5. e kore e taea e Material te huri i te tae, tae.
6. Kaha.

Ngā momo o ngā rauemi mō te whakakī niho

I roto i te niho hou whakamahi rauemi rerekē mō te hanga o whakakī niho. He rua huapai me ngā huakore ia o ratou. whakahere ētahi rauemi i roto i te haumanu tūmatanui noa, ētahi i whai i te utu āhua tiketike. Na, he aha e nga momo matua o hiri? I te kau, i reira e toru:

• matū;
• photopolymeric;
• wā.

Ia momo ngā momoroto, i runga i te matū ngā i roto i te hanganga o te rauemi niho whakakī rānei.

kekeno sima

Enei momo o ngā whakakī mō niho rite te nuinga o o te taonga paura me te waikawa wai. Ka rite ki te hua o te ranu, he tauhohenga matū, i roto i nei i hanga te ranunga whakapiri-rite i he te taonga o pakeke i te tetahi wā wā.

kekeno sima, i tahuri, kua wehea ano ki subgroups i runga i te matū reira i roto i te hanganga rānei, e whai ake:

• te konutea me te Phosphate;
• silicates;
• silicates me phosphates;
• polycarbonates;
• ionomers karaihe.

hiri e wha Ko te tuatahi he momo matū. A kia whakapakeke te muri e rua i te waikawa me te i ngaru marama.

Riro taua whakakī mau maitai sima:

1. utu iti.
2. Kahore he take ki te whakamahi i roto i te whakakī o mea motuhake.
3. Faingofua i roto i te rauemi tukanga tāuta te toi.

A ani i taua whakakī he drawbacks nui:

• ngaro hohoro ratou āhua, rōrahi,
• Me ratou he wā roa o te wā ki te whakaoti i solidification;
• ki te wā i raro i te mana o āhuatanga o waho ranei he ngāwari ki te anganga, hu'ahu'a;
• ki te kore tika e mau i roto i te tukanga o te whakatakoto i te hiri e pinea taea niho hauora;
• e kore e tiaki te reira ki re-putanga whakatö o caries ranei;
• paitini.

Ēnei huakore i ki te whānuitanga nui iti ranei katoa whakakī momo sima, ionomers karaihe motu. Kei te whānui whakamahia tēnei rauemi i roto i te rongoā hou, tae atu i roto i haumanu tūmataiti. E kore te mea paitini tenei hiri. Kei roto whakakā pūkōwhai e tiaki te niho i horapa atu o ngā wāhi carious. I tua atu, e kore te rauemi anake whakakiia ana te wāhi niho pae tino, engari ano hoki mai ki te tohu i roto i te tauhohenga matū. Na roto i tenei tukanga, whakakī ionomer karaihe pumau te wa roa.

rauemi konganuku

He aha e nga momo o ngā whakakī niho whakarewa? Tenei amalgam pera-ka karanga - rongoā e hāngai ana i runga i konganuku e whai i te taonga o te haamărôraa. He hiriwa, he koura, me te parahi.

kekeno Metal whai kaha nui, e kore e rewa ratou i te huware. Ahakoa tenei, i roto i te niho hou te tata kore whakamahia taua rauemi. He aha e nga āhuatanga? E rave rahi o ratou:

• mo te tāutanga o taua hiri rapua e taputapu ngaio motuhake, e kore he nei i roto i ia hōhipera;
• āta solidifies maitai;
• Ko tino rerekē i te tae niho tūturu hiri;
• kia whakawhanake caries;
• maha tuhia take o patito, reka konganuku i roto i te mangai.

whakakī kirihou

Ko te hunga e whakamahia ana i roto i ngā whakakī niho hou? Ngā momo o kekeno, i reira e rerekē, na te tākuta whiriwhiri nga mea e mahi ratou mahi tino tōtika i roto i te take motuhake. Ko tenei, he iti pea ki te tūtohu ratou tūroro rauemi kirihou tohunga. Ahakoa te torutoru noa matahiti i ma'iri a'e, he hiri taua ko te rerekē auaha ki te whakarewa. He aha te kore kirihou i pupuri i tona rangatira nui i roto i ngā rauemi rongonui mo te tāutanga o whakakī niho?

Ko te mea, ko te e whakawāteatia he otinga taua te tere Tīngongo i rōrahi, e taui te tae. I tua atu, hiri kirihou e maha ai tūroro korerotia tauhohe mate pāwera pērā i hikaka, whero i roto i te mangai. I tua atu, he paitini enei rauemi.

composites

momo noa o whakakī he composites. Ratou hanganga ngā e rua matū pararopi, me te inorganic. Ua haapuai rauemi hiato i raro i te mana o ngā tukanga matū, me te radiation hihi katinga.

composites waihanga titau hangarau mōhiotanga motuhake o te faaineineraa o te niho mo tenei tukanga. Mai i roto i te ofatiraa o tetahi tukanga te kounga me te mauroa o te hiri te nui iti.

Ko te painga undoubted ko te wātea o te whānuitanga o ngā rauemi papatae e taea ki a koe te mahi ngā tukanga niho, me te mo ngā take rerehua.

hiri marama

E mea pinepine, e tika ana ki te tuhinga hoko kiritaki pea he whare hauora niho mo te wa tuatahi maheni ki te wā pērā i photopolymers. He aha te mea te reira tino? E mea ohie roa - te reira te taua composites ranei ionomers karaihe e kua tāutatia ki te rama UV motuhake. E whakamahia ēnei momo o ngā whakakī i roto i te niho atu maha atu i ētahi atu.

I teie mahana, ko reira uaua ki te kitea he whare hauora, e kore e nei i tapaea he taua mahi rite photopolymerization. He aha, Na, i nga painga o enei momo o ngā whakakī mō niho?

1. Kaha.
2. Plasticity.
3. Rerehua.
4. Easy ki te tāuta.
5. hua Tere.
6. Ngaro o matū paitini i roto i te waihanga.

Ki te photopolymers kawea fakafoki mai o nga niho mua. āhuatanga Material tukua "sculpt" te āhua ataahua tika, i runga nei painlessly whakatika te hua mā hihi katinga radiation. Ko te kupu, katoa i roto i te kotahi haere, ka taea e koe te kawe i roto i te tukanga i runga i te maha o ngā niho.

Otiia i konei te te niho roa i roto i tenei ara ko rawa uaua ki te whakaki i - e kore te mea noa e taea ki te tae te rama ki te rohe e hiahiatia ana o te kōhao-waha.

rauemi rangitahi

E mea pinepine, he tika te tākuta ki te tāuta i te whakakī rangitahi mō ngā take whakaora. ki taua whakaritenga rauemi e iti: kua reira ki te kati i te poka i roto i te niho mo te wā o te maha ra ki te wiki, i muri nei e taea e ngāwari ki te tango i te hiri.

whakakī Rangitahi anganga, ka whiwhi nui moe, e noho, kia kore e ratou whakaturia he wā roa.

E mea pinepine, taua rauemi e tapiritia ki taero. reira Ko takanga taea o te reka mangai ranei kakara kino.

Ngā momo o ngā whakakī poto he e whai ake nei:

• tātaritanga;
• tikanga mo te maimoatanga haumanu;
• hiri hoki prosthetics.

he aha niho, me te hiritia ake tamariki?

e kore noa whakaaro tokomaha ngā mātua e pā ana ki taua tamaiti, me te he pakeke, e hiahia ana koe he niho tirohanga ngā. He aha te hamani niho, ki te tonu hohoro ratou hinga i roto i? I roto i te meka, tei reira ki runga ki te āhua o te hauora waiu niho tūturu. Na reira, Me ki kia hiritia niho i kotahi, te taenga atu ano tetahi tohu mō tenei tukanga tamariki.

I roto i tenei take, he mea nui ki te whiriwhiri i ngā rauemi haumaru. I roto i te pediatric whakakī whakamahi niho kei roto köwhai (ki te ārai i te hanganga anō o caries niho). He nui māmā ki te whakamahi i ngā rauemi e whakapakeke i raro i te marama hihi katinga - i roto i te maimoatanga o ngā tamariki tino maha whakamahia taua kekeno. Ngā momo o kekeno, e he nei tino hira i roto i te mahi niho o ngā tamariki, te aroaro ionomer karaihe me composites.

whakakī tae mō ngā tamariki: he aha te mea te reira?

He minamina ana i roto i te mahi niho, tae maitai whakakī niho o ngā tamariki. Momo o ngā rauemi kua oti te whakarite e te kaiwhakanao.

Bright, rite kerepeti, meinga whakakī mahu'inga'ia mo'oni, reira whakaiti te wehi o te tākuta i roto i ngā tamariki.

Taua rauemi hoki he kaha nui. I roto i te nuinga o te wā, pumau te reira i roto i ngā tamariki ki runga ki te huringa o niho. Haunga e pai te oro whakakī tae, he kirihou reira, a ka tango tona tāutanga he wa poto.

He aha ki te whiriwhiri whakakī? kia tūtohu momo o kekeno e hiahiatia ana i roto i te take ngā hauora tohunga anake. Mai hiahia koe ki te aromatawai ngaio te āhuatanga, he momo o ngā āhuatanga, me te whakatau he aha te ahua o te rauemi he pai hāngai hoki tenei manawanui ngā.
