I roto i ngā kupu kotahi: te kaha me te ataahua . Ka whakapakeke te oumu whakahinuhinu i te zirconia kia rite ki te niho tūturu. Ka rite te āhua o te oumu porcelain ki te niho tūturu. He rerekē ngā pāmahana, he rerekē ngā tikanga, he rerekē ngā mahi - ā, kāore e taea e tetahi te mahi i te mahi a tetahi.
Ka whakamāramahia e tēnei aratohu ngā mahi a ia mīhini, ngā take kāore e taea te whakawhiti tetahi ki tetahi, me pēhea te whakatau ko tēhea (ko tēhea huinga rānei) e hiahiatia ana e tō taiwhanga. Hei te mutunga, ka mōhio koe ko tēhea waeine e whakahaere ana i te kaha hanganga, ko tēhea e whakahaere ana i te atarangi me te mārama, me pēhea te whakarite tahua i runga i te mea he karauna me ngā piriti zirconia te nuinga o tō taiwhanga, he whakakikorua me ngā uku paparanga rānei, ā, ko ēhea ngā āhuatanga e whai tikanga ana ina whakataurite ana koe i ngā oumu - ehara i te pāmahana mōrahi anake i runga i te pepa āhuatanga.
He aha i hiahiatia ai e ngā taiwhanga niho ngā momo oumu e rua
He ngohengohe tonu, he kirikiri tonu te zirconia e piri ana i te mīhini mira — ka taea e koe te tapahi kia rua ki ō maihao. Ka taea te whakamahi hei whakaora hauora i muri i te tahu i runga ake i te 1,400°C, he tukanga e kiia nei ko te sintering, koinei te mahi a te oumu sintering zirconia. Ko te whakarite kia rite te ahua o taua whakaora ki te niho tūturu — te atarangi tika, te mārama tika — he taahiraa anō: te whakatakoto i te porcelain, te tae, me te whakakanapa i roto i te oumu porcelain, e rere ana i waenga i te 700–1,000°C.
Ka whakautu tētahi mīhini "ka roa?" Ko ētahi atu whakautu "he pai te āhua?" He rerekē rawa ngā awhe pāmahana o aua pātai e rua, ā, he rerekē rawa ngā taputapu e hiahiatia ana. Koia tonu te take e kore ai koe e kite i te rārangi taputapu o te taiwhanga niho e whakaaro ana he mea whakawhiti ēnei.
He aha te oumu Zirconia Sintering me pēhea te mahi?
Kotahi te mahi a te oumu whakawera zirconia: he whakakotahi i ngā matūriki zirconia i raro i te wera nui tonu kia ngaro ai ngā pūwero iti o roto, kia memeha ai te rauemi mai i te āhua pūwero ki te tata ki te matotoru. Ko taua tukanga — te whakakīkī — koinei anake te huarahi e whiwhi ai te zirconia i tōna kaha whakamutunga, tōna mārama, me tōna tika o ngā āhuatanga. Kaua e mahi i tēnā, ā, ko tāu i mira ai he uku ngohengohe tonu, kāore e tika kia uru ki te waha o te tūroro.
Koinei te āhua o te tukanga mahi: ka mirahia e te tohunga hangarau te āhua whakaora mai i tētahi poraka zirconia kua oti te whakakoi ("kakariki" "mā" rānei), he ngohengohe, he ngāwari hoki te tapahi i tēnei wā. Ka whakanuia rawatia te hoahoa mā te 20–25% hei whakaaro mō te whakahekenga i te wā e tahuna ana. Kātahi ka tukuna te wahi kua mira ki roto i te oumu whakakoi, ka whai i te pihi whakamahana, pupuri, me te whakamatao kua tūtohutia e te kaihanga, ka whakaheke ki raro ki ōna rahi hoahoa whakamutunga, me te whakakīkī i te wā kotahi. Ka honoa ia taahiraa o taua mekameka - ahakoa he iti noa te peka o te pihi whakakoi ka puta ake i muri mai hei raruraru taunga ki te waha o te tūroro.
Ko te tino take o te rahunga ehara i te mea ko te koretake o te pāmahana tihi — engari ko te koretake o te ōritetanga o te pāmahana i roto i te rūma, e puta mai ana he rerekētanga atarangi i roto i te puranga kotahi, he ahotea ā-roto me te piko rānei i roto i ngā anga piriti nui ake e wera koretake ana. Koinei tonu te raruraru i hangaia ai te Dentex Q7 hei whakaoti, mā te whakamahi i tana hangarau ARCS (Automatic Rapid Compensation Sintering) motuhake: he pūnaha hiki kore-wiri e whakarite aunoa ana i te tawhiti i waenga i te mea mahi me te pakitara o te rūma, ka hoatu ki a koe te mana whakahaere kaha ake mō te wera, te pupuri, me te whakamatao kia taea ai e koe te tapahi i te wā huringa me te kore e whakaiti i te mātotoru, te mārama rānei.
Koinei te mīhini tino pai mō ngā mea katoa i hangaia ki runga i te papa zirconia: ngā karauna takitahi me ngā karauna katoa, ko te mea nui ko te ōritetanga o te atarangi o ia puranga; ngā anga piriti maha-wae, ko te wāhi e hiahiatia ana kia ōrite te pāmahana kia kore ai e piko te pakitara kāore i te ōrite; me ngā whakahoutanga me ngā abutment ritenga e tautokona ana e te whakatō, ahakoa he iti noa te nekehanga o te tere whakaheke ka taea te whakararu i te tika o te taunga ki te whakatō.
He aha te whakamahinga o te oumu porohita niho?
Ka taea e te oumu whakapūmau te whakapakeke i te zirconia, engari kāore e taea te hoatu i te atarangi me te māramatanga o te niho tūturu ki te whakaora - koinei te rohe o te oumu porcelain. Ko tana mahi matua e kapi ana i ngā taahiraa e toru: te whakatakoto paparanga porcelain, te wāhi e hangaia ai e te tohunga hangarau he uku paura i roto i ngā paparanga whai muri i runga i te zirconia, i te papa whakarewa rānei, ka tahuna ia paparanga; te tae, te wāhi e pania ai he tae wai hei whakatikatika i te atarangi o te rohe; me te whakakanapa, te wāhi e puta ai te mata maeneene, whakaata-mārama i te tahunga whakamutunga e whai ana i te enamel tūturu. Ka taea hoki e ngā oumu porcelain te whakahaere i te whānuitanga o ngā rauemi i ngā oumu whakapūmau - te porcelain whakapūmau feldspathic, te paparanga porcelain i runga i ngā whakaora PFM (porcelain-fused-to-metal), me te tae me te whakakanapa o te lithium disilicate me ētahi atu karāhe-uku. Ko te tikanga, ko ngā mea katoa e hiahia ana ki te whakaotinga ataahua ka haere mā roto i te oumu porcelain i tētahi wā.
Ko te rerekētanga taputapu nui rawa atu i waenga i te oumu porcelain me te oumu sintering ko te pūnaha korehau. Ki te kore e tangohia te hau i roto i te ruma i te wā e tahuna ana, ka mau te paura porcelain i ngā mirumiru hau moroiti, ā, ka marara aua mirumiru i te mārama - koia tonu te take he ahua kapua, he kirikiri rānei te whakaora kāore i te korehau, kaua e mārama. Ka taea e ngā tākuta niho me ngā tūroro te kite i taua āhua "mate" ki te kanohi tahanga, koia te take ehara te tahunga korehau i te whakapai ake i runga i te oumu porcelain - he tūāpapa tēpu. Haunga te korehau, he mea nui anō te ōritetanga o te pāmahana me te tika o te kaupapa: he nui ngā nekehanga rerekētanga puta noa i te ruma hei whakaputa i te kore ōritetanga o te atarangi i roto i te puranga kotahi, ā, ka waiho e te pihi whakamahana/whakamatao koretake te hanganga karaihe o roto o te porcelain kia kore e ōrite, e puta ana he mārama papatahi me te mutunga mata mangu.
Te Oumu Sintering me te Oumu Porcelain: Ngā Rerekētanga Matua i te Tirohanga Poto
Kia mārama koe ki te mahi a ia mīhini, he māmā noa iho ngā rerekētanga:
Te roa o te pupuri i te pāmahana teitei, ngā tere piki e whakahaeretia ana
Ngā huringa tahu maha-wāhanga, paparanga pai
Pūmārō matua
Ngā wāhanga whakamahana pāmahana-tiketike, te whakahaere pāmahana tino tika
Pūnaha korehau, whare pukapuka hōtaka whānui
Ka taea e te kotahi oumu te whakakapi i te tetahi atu?
Kāo — ā, e rua ngā huarahi e tika ana mō te take. Ehara i te mea he "wera noa iho".
Kāore e taea e te nuinga o ngā oumu porcelain te eke ki te awhe 1,400°C neke atu e hiahiatia ana e te zirconia kia whakamātotoru. Ahakoa te waeine onge e kī ana he taea tana, kāore i hangaia me ngā waeine whakamahana, ngā waeine whakamahana rānei kua whakaritea mō taua momo kawenga pāmahana teitei tonu — pēhia kia kaha, ā, ka tere te whakapoto i te roa o te ora o te taputapu. Haere ki tētahi atu taha, ā, ka huri te raruraru: he oumu sintering, ahakoa he wāhi nui hei pupuri i te pāmahana, kāore he pūnaha korehau, ā, kāore hoki he kaupapa maha-wāhanga pai e hiahiatia ana e te tahu porcelain. Whakamahia tētahi mō te whakatakoto paparanga porcelain, ā, tera pea ka puta he hua mirumiru, he puhoi — ā, he rauemi maumau.
Mena he rerekē te ranunga o ngā kēhi o tō taiwhanga, ā, kāore he kāwai kotahi e tino kaha ana ki tō rahinga, he huarahi whaitake te whakamahi i te oumu pēhi-me-porcelain hei whakatutuki i ngā hiahia e rua i roto i te kotahi waeine. Engari, ki te mea ko te mahi karauna-me-piriti zirconia tō pakihi matua, ā, kei te whai koe i te putanga nui, pumau, he nui te rahinga, ko te oumu sintering motuhake tonu te haumi haumaru ake - koinei tonu te hanga o ngā mīhini motuhake pēnei i te Dentex Q7 me te Q56 .
Me pēhea te whiriwhiri i te oumu tika mō tō taiwhanga
Ko te tīmatanga mō tētahi whakatau hoko ko te mea e tino hangaia ana e tō taiwhanga — ehara i te mea ko tēhea whārangi whakaritenga te mea nui rawa atu.
Ko ngā taiwhanga e whakahaere ana i te nuinga o ngā mahi karauna-me-piriti zirconia me whakarite he oumu sintering motuhake he kaha teitei, me te aro nui ki te rahi o te puranga me te kaha mura tere - hei tauira, ko te Dentex Q56 ka taea te whakahaere i te 100+ waeine ia huringa puta noa i te tatūnga parai 3-paparanga, i hangaia mō ngā taiwhanga tere-whakaputa. Tērā pea ka kitea e ngā mahi iti ake te Dentex Q7 - 80+ waeine ia huringa me te huringa sintering tere 60-meneti tae atu ki te whakamatao - he nui atu i te rawaka. Ko ngā taiwhanga e aro ana ki ngā veneers me ngā whakahoutanga ataahua paparanga me aro ki te mahi korehau me te whare pukapuka kaupapa hohonu i te taha oumu porcelain, kaua ki te whai i ngā pāmahana tihi teitei kāore e hiahiatia ana e rātou. Ko ngā taiwhanga he kawenga take whakauru - zirconia me te karāhe-uku e rua e huri ana - ka mutu ka whakahaerehia he huinga: he oumu motuhake mō te kawenga mahi tuatahi me te waeine maha-mahi mō ngā kāwai iti-rahi. Ā, i runga i te tauine: e hiahia ana te whare hauora iti ki tētahi mea pono, ngāwari hoki te whakahaere, ko te whare hanga niho rūpahu nui ia me whakarite kia rite ki te kaha o ia huringa me te kaha ki te whakahaere tonu me te kore e mutu te mahi.
