Ka whakaitihia e te whakakanapa hiko te ōrau o te rino me te whakanui ake i te chromium i runga i te mata. Ka whai wāhi tēnei ki te hanga i tētahi paparanga kore mahi me te ātete waikura kua piki ake.

Ahakoa ēnei maimoatanga, ka taea tonu te waikura. I kitea te waikura pitting i runga i ngā rōpū pupuri SS 3-whiri, SS 6-whiri, me Dead Soft i roto i ngā otinga i te wā o te aromatawai. I tetahi atu taha, kāore i whakaatuhia e ngā rōpū pupuri Titanium Grade 1, Titanium Grade 5, me Gold he kino ki te waikura. I kitea ngā momo waikura rerekē, tae atu ki te waikura ā-rohe, i runga i ngā whakaurunga o ngā taputapu tapahi here orthodontic. I tino pā tēnei ki te waitohu ETM i muri i te whakahoromata autoclave me te patu huakita matū. Heoi, i whakaatuhia e ngā taputapu tapahi Hu-Friedy he ātete waikura teitei.

Te Pakari me te Ātete ki te Maukati mō te Mahi

He mea nui te pakeke me te ātete ki te kakahu hei pupuri i te mahi a te taputapu, inā koa mō te tapahi me te hopu i ngā taputapu. Ko te pakeke e ine ana i te ātete o te rauemi ki te kōpiko, ki te rakuraku rānei. Ko te ātete kakahu e whakaahua ana i tōna kaha ki te ātete ki te pirau o te mata mai i te waku, i te mirimiri rānei.

He maha ngā wā ka hono te pakeketanga ki te ātete pai ake ki te kakahu. He mea nui tēnei mō ngā taputapu e pāngia ana e te waku me te pēhanga tonu.Hei tauira, he tino pakari te tungsten carbide, ā, he iti te pakaru.He nui te pānga o tēnei ki te roa o te mau o te taputapu. He pai ake te pupuri i ngā taha o te taimana polycrystalline (PCD). Ka tapahia e ia ngā rauemi mārō pēnei i te uku me te zirconia.

I kitea i roto i tētahi rangahau he nui ake te whai huatanga o ngā pere taimana ki te tapahi i ngā karauna lithium disilicate i ngā karauna zirconia. Nā te pakeke o te rauemi tēnei. Ka whakanui ake ngā rauemi pakeke pērā i te zirconia i te waku. Ka tere ake te kakahu o te kōhao taimana, ā, ka whakaiti i te roa o te ora o te taputapu. I kitea i roto i te rangahau ko te whakamahi i te zirconia 5YSZ, he iti ake te pakeke i te 3Y-TZP, i hua ake ai he iti ake te rerekētanga o te pakari me te kakahu o ngā pere.

Ko te rangahau i ngā rauemi polymeric mō ngā taputapu orthodontic i uru ki ngā whakamātautau rakuraku mā te whakamahi i te indenter Rockwell. Ko ēnei inenga pakeke rakuraku, i whiwhihia mā te profilemeter whakapā, i whakaatu i te hononga ki te pakeke o Shore. Heoi, i whakaatuhia e te rangahau me aromatawai motuhake te whakatauranga o te ātete kakahu reti. E whakaatu ana tēnei ahakoa e whakamahia ana ngā indenters Rockwell i roto i te whakamātautau pakeke, kāore te whanaungatanga tika i waenga i te tauine pakeke Rockwell me te ātete kakahu i whakamāramahia mārama hei hononga tika i roto i ēnei kitenga. Ko ngā tikanga ine pakeke rerekē, pērā i te pakeke indentation (pēnei i a Shore) me te pakeke rakuraku, ka taea te whakaputa hua kāore e taea te whakataurite nā ō rātou mātāpono ine rerekē.

Te Kaha Kume me te Ātete ki te Ngenge

He mea nui te kaha kume me te ātete ngenge mō te hanganga me te roa o te ora o te taputapu. Ka ine te kaha kume i te ahotea nui rawa atu ka taea e te rauemi te tu atu i mua i te pakaru ina totorohia, ina kumea rānei. Ko te ātete ngenge e whakaahua ana i te kaha o te rauemi ki te tu atu i ngā huringa ahotea maha me te kore e pakaru. Ka pāngia ngā taputapu e ngā kaha piko, takahuri, me te tapahi maha i te wā e whakamahia ana.

He nui te pānga o te kawenga huringa ki te ātete ngenge o ngā rauemi. He pono rawa tēnei mō ngā taputapu pēnei i ngā kōnae endodontic. He wāhi nui tō te āhua o te awaawa. Ko te pikinga o te koki me te hekenga o te radius o te piko ka whakaiti i te ātete ngenge huringa. He iti ake te ātete whati o ngā kōnae i roto i ngā awaawa he koi ake ngā koki me te iti o te radius o te piko. Ka hua ake tēnei i te kaha pēhi me te kaha kume.
