Kupu Whakataki
Ehara i te mea he whiriwhiri rauemi noa iho te whiriwhiri i waenga i ngā waea āwhata NiTi tuku iho me te Cu-NiTi; engari he pānga tika ki te tuku kaha, te whakamarie o te tūroro, me te matapae i te tūnga wawe. Ahakoa e whakanuia ana ngā waea e rua mō te whanonga tino ngāwari, ka tāpirihia e te Cu-NiTi te mana whakahaere pāmahana-aro ka taea te whakarite i te whakaaturanga kaha i roto i ngā āhuatanga haumanu motuhake. Mā te mārama ki te rerekētanga o ēnei koranu i roto i ngā āhuatanga tango, te whānuitanga whakahohenga, me te urupare koiora ka āwhina i ngā tākuta ki te whakataurite i te kōwhiringa waea ki te kaha o te pupuhi, te pūnaha whāiti, me ngā whāinga maimoatanga. Kei raro nei te whakamārama i te wāhi e tukuna ana e te Cu-NiTi he painga nui, te wāhi e whai hua tonu ai te NiTi paerewa, me te whakatau ko tēhea kōwhiringa e pai ana mō tētahi take.
He aha te Hiranga o te Kōwhiringa NiTi me te Cu-NiTi Archwire
Te taenga mai ongā koranu mahara āhuai huri i te hangarau koiora orthodontic, i nekehia te tauira mai i te maitai kore waikura kawenga teitei ki te hangarau kaha-māmā tonu. Ko te kōwhiringa i waenga i ngā waea āwhata nikara-titanium (NiTi) tikanga me te parahi-nikara-titanium (Cu-NiTi) he peka nui i roto i te whakamahere maimoatanga.
Ahakoa he tino ngāwari ngā koranu e rua, ko ō rāua whanonga thermodynamic rerekē e tohu ana i te whakawhiti o te ahotea miihini ki te hononga periodontal (PDL). Mā te mārama ki ēnei āhuatanga whakarewa ka taea e ngā tākuta te arotau i te nekehanga o ngā niho me te whakaiti i ngā tūponotanga iatrogenic.
Pānga ki te whakatikatika i te wāhanga tuatahi
Ko te whakatikatika me te whakahāngai i ngā wāhanga tōmua e hiahia ana ki ngā kaha hei tīmata i te hanga hou o ngā pūtau, me te kore e puta te hyalinization, te removal rānei o te pakiaka. Ko te nekehanga niho orthodontic tino pai e hiahiatia anangā kaha mārama tonukei waenga i te 50g ki te 150g, i runga i te horahanga o te mata o te pakiaka o te niho.
Ka whakaratohia e te NiTi tikanga he kaha pumau tonu i runga i ngā piko nui, engari ka taea e tōna pihi tango te rerekē i runga i ngā ātete hanga. Ko te Cu-NiTi, i tetahi atu taha, ka tukuna he kōtaha uta me te tango tino tika, kia mau tonu ai te kaha e whakamahia ana i roto i te paepae koiora pai rawa atu ahakoa ka pāngia ngā niho kua tino hē.
Te pānga o te kōwhiringa ki te tuku kaha me te whakamahere
Ko te kōwhiringa o ngā waea āwhata te mea e whakatau ana i te whai huatanga me te matapae o te raupapa waea katoa. Nā te mea ka taea te hanga i ngā koranu Cu-NiTi kia whakahohehia i ngā pāmahana motuhake, ka taea e ngā tākuta te whakarite i te tuku kaha i runga i te taiao ā-waha, kaua ki te whakawhirinaki noa ki te piko ā-pūkaha.
Mā tēnei urupare wera ka taea te whakauru i ngā waea tapawhā nui ake (hei tauira, 0.016″ x 0.022″) i mua ake o te raupapa maimoatanga. Ka noho ngāwari te waea ki te whakakorikori i te pāmahana rūma kia māmā ai te whakauru, ā, ka āta whakaatu i tōna kaha kua whakaritea i a ia e taunga ana ki te wera o te tinana o te tūroro, ā, ka whakatikatika i te mahere maimoatanga whānui.
Ngā Rerekētanga o ngā Rauemi NiTi me Cu-NiTi
Ko ngā rerekētanga mahi matua i waenga i ēnei waea āwhata i ahu mai i tō rātou hanganga whakarewa. Ko te NiTi superelastic tikanga he koranu takirua tata rite tonu o te nikara me te titanium.
Ka whakauruhia e te Cu-NiTi te parahi ki roto i te anga—ko te tikanga he 5% ki te 6% o te taumaha katoa o te koranu—me ētahi whakarerekētanga iti ki ngā ōwehenga nikara me te taitāne, ā, i ētahi wā ka tāpirihia te chromium hei whakatikatika i ngā pāmahana whakawhiti.
Te kaha rawa o te ngāwari, te mahara āhua, me te whakahohenga wera
Ka pāngia ngā koranu e rua e te panonitanga āhua hurihuri i waenga i te āhua austenitic pakari, pāmahana-tiketike me te āhua martensitic ngāwari, pāmahana-iti. Heoi, mā te tāpiri o te parahi ka whakawhāitihia te porowhita hysteresis—te āputa i waenga i ngā ānau kaha uta (whakahohe) me te wetewete (whakakore).
Ko te tikanga o te hysteresis whaiti ake ko te kaha e hiahiatia ana hei whakauru i te waea ki roto i te whāriki he tata atu ki te kaha e tukuna ana e te waea i a ia e hoki ana ki tōna āhua taketake. Nā tēnei whai huatanga thermodynamic ka nui ake te tuku pūngao, ā, ka iti ake te whara ki ngā hanganga periodontal i ngā wāhanga tuatahi o te maimoatanga.
Te whakataurite i ngā taumata kaha me te whānuitanga mahi
He rerekē rawa ngā taumata kaha me ngā awhe mahi ina tātarihia ngā paparanga tango o ngā rauemi e rua. Ka taea e ngā kaha tango NiTi superelastic paerewa te heke iho i te 30% ki te 40% i runga i te piko 2mm, ka hua ake he nekehanga niho kore taurite i te wa e ora ake ana te waea.
He papatahi te papatahi o te tango i te kaha e mau tonu ana i te Cu-NiTi, ā, he maha ngā wā ka mau tonu te rerekētanga o te kaha i roto i te tawhē iti o te 10% ki te 15% puta noa i te awhe piko kotahi. He mea nui tēnei ōritetanga hei pupuri i te tohu koiora kore e mutu e hiahiatia ana mō te mahi osteoclastic me te osteoblastic whai hua.
| Taonga | NiTi Tino Āhuahira Tikanga | Cu-NiTi (Rērekētanga 35°C) |
|---|---|---|
| Te Hanganga o te Koranu | Rua (Ni, Ti) | Te toru (Ni, Ti, 5-6% Cu) |
| Porowhita Hysteresis | Whānui | Whāiti |
| Rerekētanga Papaaho Whakakaha | 30% – 40% (neke atu i te 2mm) | 10% – 15% (neke atu i te 2mm) |
| Te Āhuatanga Wera | Iti/Waenga | Tino Tairongo |
Ngā Take Hauora e Ārahi ana i te Kōwhiringa o te Archwire
I tua atu i te pūtaiao rauemi, ko te whakamahinga haumanu o te NiTi me te Cu-NiTi me mārama ki ngā taurangi motuhake mō te tūroro. Me paunatia e ngā tākuta niho te kaha o te korenga o te hononga, te manawanui o te tūroro ki te mamae, me ngā whakaritenga ā-pūkaha o te pūnaha whāiti kua whiriwhiria.
Te whakataurite i te momo waea ki ngā hiahia o te pouaka
He mea nui te whakataurite i te momo waea ki ngā hiahia motuhake o te pouaka kia pai ai te whakataurite. Mēnā he nui te kikī o te waea, he nui rānei ngā pahūtanga o te puku, ka tūpono te waea pakari ki te wetewete i te hononga o te taura, ki te nui rawa rānei te mamae o te tūroro.
Ka taea te hono ngāwari i tētahi waea Cu-NiTi kua whakahohehia e te wera (pērā i te 0.014″, 0.016″ rānei te rahi) i roto i te āhua makariri, martensitic. I te mahana haere ki te pāmahana ā-waha tata ki te 37°C, ka huri ki te austenite, ka pā he kaha ngawari, tonu. Mō ngā take whakatikatika ngawari kāore e hiahiatia he piko nui, he maha ngā wā ka ranea te NiTi tikanga, ā, he otinga tino whai hua.
Te aro ki te pāmahana me te whakamarie o te tūroro
Ko te aro o te waea āwhata ki te pāmahana e pā tika ana ki te whakamarie o te tūroro. Ko te kaha o te Cu-NiTi ki te wera he tikanga whakaora ā-roto mō te tūroro.
Mena ka pāngia te tūroro e ngā mamae ā-rohe whai muri i te whakarerekētanga, mā te inu i ngā wai matao (mai i te 5°C ki te 15°C te pāmahana) ka whakamatao te waha mō te wā poto, ka hoki te taura whatu ki tōna wāhanga martensitic ngawari. Ka mutu tonu te tukunga o te kaha, ka whakarato i te mamae wā poto me te kore e hiahiatia he wawaotanga rongoā.
Ngā herenga, te whakahaere, me ngā tauwhitinga utu
Ahakoa ōna painga koiora-ā-tinana, he iti noa ngā herenga haumanu me ngā herenga mahi a te Cu-NiTi. Mā te whakaurunga o te parahi ka nui ake te ngāwari o te koranu ki te pakaru i raro i ngā piko koi, ā, kāore i te pai mō ngā mahi whakairo uaua i te taha o te tūru, ki te whakaritea ki te maitai kore waikura, ki te NiTi paerewa rānei.
Hei tāpiritanga, me whakauru ngā utu hoko ki roto i ngā mahi whakahaere. Ko te utu mō ngā waea kōhatu Cu-NiTi he 20% ki te 40% te nuinga, he nui ake i te NiTi superelastic tikanga. Me whai huarahi rautaki tēnei ki te whakahaere taonga kia mōhio ai kei te rāhuitia ngā waea kounga teitei mō ngā wāhi e tino whai hua ana i ō rātou āhuatanga.
Me pēhea te aromatawai i te Cu-NiTi i tua atu i ngā kereme mahi
Ko te aromatawai i te Cu-NiTi me titiro ki tua atu i ngā kereme hokohoko taketake, me te tirotiro anō hoki i ngā whakatakotoranga pāmahana me ngā tikanga whakapūmau kounga a te kaihanga.
Mō ngā mahi ratonga niho nui me ngā Whakahaere Ratonga Niho (DSO), mā te whakarite i ngā hoko e ahu mai ana i ngā inenga ka taea te ine ka whakarite i ngā putanga haumanu ōrite, ā, ka whakaitihia hoki ngā rahunga waea ohorere.
Ngā whakaritenga me ngā awhe pāmahana whakawhiti
Ko te whakatakotoranga tino hira mō te Cu-NiTi ko tōna pāmahana Austenite Finish (Af), e whakatau ana i te wā e tino kaha ana te waea. Ko te tikanga, ka tukuna e ngā kaihanga te Cu-NiTi i roto i ngā momo Af motuhake hei whakatutuki i ngā āhuatanga haumanu rerekē.
Ka noho kaha tonu te waea 27°C i roto i te nuinga o ngā āhuatanga taiao, he rite tonu te mahi ki te NiTi superelastic paerewa engari he iti ake te hysteresis. Ka whakahohehia te waea 35°C i raro noa i te pāmahana tinana noa, koia te whiringa paerewa mō te nuinga.ngā tono orthodonticMe nui ake te pāmahana o te waea 40°C i te wera tinana taketake kia tino whakahohea ai, he mea tino pai mō ngā tūroro e pāngia ana e te mate niho nui, ina ko ngā kaha mama rawa, wā poto noa iho ka taea te whakamanawanui.
| Rerekētanga Pāmahana Af | Āhua Whakahohe i te 37°C (Mahana Tinana) | Tohu Hauora Tuatahi |
|---|---|---|
| 27°C | Tino Austenitic (Hohe) | He iti te piri o te tangata, he tere te whakatikatika, he manawa-waha |
| 35°C | Tata ki te Austenitic Katoa (Hohe) | Te whakataurite me te whakarārangi paerewa, te whakakīkī taurite |
| 40°C | Martensitic Āhua (Ngāwari) | Te nui o te kikī o ngā niho, ngā tūroro e ngoikore ana te niho |
Te whakahoromata, te takai, me ngā arowhai ture
He paearu aromatawai nui ngā whakaritenga ture me ngā tikanga whakahoromata. Me tutuki ngā waea kōhao Cu-NiTi kounga teitei ki ngāNgā paerewa ISO 15841mō ngā waea orthodontic, kia whakarite ai i te hototahitanga koiora me te whakapuakitanga kaha pono.
Ahakoa ko ngā tikanga whakamahi kotahi te paerewa ahumahi hei ārai i te poke whakawhiti me te ngenge o ngā rauemi, ka taea e ētahi tautuhinga haumanu te whakamana i ngā tukanga whakahoromata. He mea nui kia mōhio ko ngā huringa autoclave paerewa (hei tauira, 134°C mō te 3 ki te 5 meneti) ka taea te whakarerekē i te hanganga tioata o ngā koranu mahara āhua i runga i ngā huringa maha, ka taea te neke i te pāmahana Af me te whakaheke i ngā āhuatanga superelastic. Nō reira, he mea whakahau te aromatawai i ngā aratohu motuhake a te kaihanga mō te whakaaturanga wera i te wā e takai ana me te whakahoromata.
Me pēhea te whiriwhiri tika i te Archwire
Ehara te whakatau i waenga i te NiTi tikanga me te Cu-NiTi i te kōwhiringa rua, arā, ko tētahi e pai ake ana mō te katoa; engari, ko te mea nui ko te whakamahi i ngā āhuatanga whakarewa tika i te wāhanga tika o te wawaotanga koiora-ā-tinana.
Mā te whakatū i tētahi kawa raupapatanga waea paerewa ka taea e ngā kaimahi te whakamahi pai i ngā kaha o ngā koranu e rua.
He anga whakatau taahiraa-i-te-taahiraa
Ka tīmata tētahi anga whakatau pūnaha mā te aromatawai i te nui o te korenga o te niho me te hauora o te niho. Tuatahi, aromatawaihia te tawhiti i waenga i ngā taura me te kaha o te piko o te niho e hiahiatia ana; ko te piko teitei e hiahia ana kia ngāwari te whakangawari o te Cu-NiTi i te wera.
Tuarua, aromatawaihia te horahanga o te mata o te pakiaka me ngā taumata o te wheua; ko te wheua kua pakaru me whai i ngā kaha tango māmā rawa, rite tonu o te waea Cu-NiTi 35°C, 40°C rānei. Hei whakamutunga, whakaarohia te whakahaunga awhi (hei tauira, te here-whaiaro me te tikanga), i te mea ko tete iti o te waku o ngā pūnaha here-whaiaroka hono tahi me te papatahi tango papatahi o ngā koranu whai parahi.
Āhea te whiriwhiri i te NiTi me te Cu-NiTi
Ko te NiTi tikanga tonu te mea tino whai hua, tino utu hoki mō ngā wāhanga whakataurite noa, ngāwari hoki, ina kore he piko nui, ā, kāore e hiahiatia he whakahaere wera.
I tetahi atu taha, ko te Cu-NiTi te rauemi pai rawa atu mō ngā whakatikatika tīmatanga uaua, ngā niho tino hurihuri, me ngā tūroro e pāngia ana e te wera. Mai i te tirohanga whakahaere mahi, mā te whakamahi i te Cu-NiTi i roto i ngā take uaua ka taea te whakaiti i te maha o ngā whakawhiti waea i te wā tōmua mā te kotahi ki te rua ngā haerenga. Ko tēnei whakaiti i te wā tūru me te mamae o te tūroro ka whakakore i te utu wāhanga tīmatanga teitei ake o te 20% ki te 40%, ka arotau i te whai huatanga haumanu me te reremahi mahi.
