ʻOi aku ma mua o 36 miliona ʻAmelika ʻaʻohe niho, a ʻo 120 miliona mau kānaka ma ʻAmelika e nalowale ana ma kahi o hoʻokahi niho. Me kēia mau helu i manaʻo ʻia e ulu aʻe i nā makahiki ʻelua e hiki mai ana, ua manaʻo ʻia e ulu nui ka mākeke no nā niho niho paʻi 3D.
Ua ʻōlelo ʻo Sam Wainwright, Dental Product Manager ma Formlabs, i ka wā o ka webinar hou loa o ka hui ʻaʻole ʻo ia e "kahaha i ka ʻike ʻana i ka 40% o nā niho niho ma ʻAmelika i hana ʻia me ka paʻi 3D," e ʻōlelo ana he kūpono ia "ma ka pae ʻenehana no ka mea aia. ʻaʻohe lilo o nā mea. Ua ʻimi ka loea i kekahi o nā ʻenehana i hōʻoia ʻia e hana no nā niho niho paʻi 3D maikaʻi aʻe. ʻO ka webinar, i kapa ʻia Hiki ke nānā maikaʻi nā niho niho paʻi 3D?, hāʻawi ʻia i nā niho niho, nā ʻenehana, a me nā mea makemake e hoʻohana i ka paʻi 3D no ka hoʻomaikaʻi ʻana i nā niho niho, nā ʻōlelo aʻoaʻo no ka ʻoki ʻana i nā kumukūʻai waiwai a hiki i 80% (hoʻohālikelike ʻia me nā kāleka denture kahiko a me ka acrylic); e hana i nā ʻanuʻu liʻiliʻi no ka loaʻa ʻana o nā hopena kiʻekiʻe, a pale i nā niho mai ke ʻano kūlohelohe.
"He mākeke hoʻonui mau kēia me nā koho he nui. He mea hou loa nā niho niho 3D i paʻi ʻia, ʻo ia hoʻi no nā prosthetics hiki ke hoʻoneʻe ʻia (kekahi mea ʻaʻole i hoʻohana ʻia) no laila e lōʻihi ka manawa no nā labs, nā niho a me nā mea maʻi e maʻa ai. Hōʻike ʻia ka mea no ka hoʻohana lōʻihi akā ʻo ka hoʻohana wikiwiki ʻana i kēia ʻenehana ʻo ia ka hoʻololi koke ʻana a me nā niho niho manawaleʻa, ʻoi aku ka liʻiliʻi o ka hiki ke hele i nā ʻoihana niho ʻaʻole e holo i kēia ʻenehana hou. Manaʻo mākou e ʻoi aku ka maikaʻi o ka resins, ikaika a ʻoi aku ka nani i ka manawa, "wahi a Wainwright.
ʻO ka ʻoiaʻiʻo, i ka makahiki i hala, ua hoʻokō ʻo Formlabs i ka hoʻomaikaʻi ʻana i nā resins āna e kūʻai aku ai no nā limahana lapaʻau e hana i nā prostheses waha, i kapa ʻia ʻo Digital Dentures. ʻAʻole like kēia mau resins hou i ʻae ʻia e FDA i nā niho kuʻuna akā ʻoi aku ka liʻiliʻi ma mua o nā koho ʻē aʻe. Ma ka $299 no ka resin base denture a me $399 no ka resine niho, ua manaʻo ka hui he $7.20 ke kumukūʻai resin no ka niho maxillary. Eia kekahi, ua hoʻokuʻu hou ʻo Formlabs i ka mea paʻi Form 3 hou, e hoʻohana ana i nā kākoʻo paʻi māmā: ʻo ia hoʻi, ua maʻalahi ka maʻalahi o ka hana hope. E ʻoi aku ka wikiwiki o ka wehe ʻana i ke kākoʻo ma ka Pepa 3 ma mua o ka Pepa 2, ʻo ia hoʻi ka liʻiliʻi o nā kumukūʻai a me ka manawa.
"Ke hoʻāʻo nei mākou e pale i nā niho mai ke ʻano kūlohelohe, a i kekahi manawa me kēia mau niho niho 3D i paʻi ʻia, pilikia maoli ka aesthetics mai ia mea. Makemake mākou e noʻonoʻo pono e loaʻa i nā niho niho e like me ke ola, nā ʻaoʻao o ka ʻōpū maoli, nā niho e nānā pono ai, a maʻalahi hoʻi e hui pū," wahi a Wainright.
ʻO ke kaʻina hana maʻamau i manaʻo ʻia e Wainright, ʻo ia ka hahai ʻana i ke kaʻina hana kuʻuna a hiki i ka ninini ʻia ʻana o nā kumu hoʻohālike hope loa me ka rim wax, pono e hana ʻia kēlā hoʻonohonoho hoʻonohonoho i kikohoʻe me kahi mīkini paʻi niho 3D e hiki ai ke hoʻolālā kikohoʻe i nā niho CAD wehe. ʻōnaehana, ukali ʻia e ka paʻi 3D i ke kumu a me nā niho, a ma hope o ka hoʻoponopono ʻana, ka hui ʻana a me ka hoʻopau ʻana i ka ʻāpana.
“Ma hope o ka hana ʻana i nā ʻāpana he nui, paʻi ʻana i hoʻokahi tona o nā niho niho a me nā kumu, a hui pū ʻia, ua loaʻa iā mākou ʻekolu mau ʻenehana no kahi niho niho 3D aesthetic. ʻO ka mea a mākou e makemake ai, ʻo ia ka pale ʻana i kekahi o nā hopena o nā niho niho kikohoʻe o kēia lā, e like me nā huahana me kahi kumu opaque a i ʻole gingiva, ʻo ia hoʻi kahi mea ʻino i koʻu manaʻo. A i ʻole e hele mai ʻoe i kahi kumu semi transluscent e waiho ana i nā aʻa i ʻike ʻia, a ʻo ka hope ke hoʻohana ʻoe i ka workflow niho splinted hiki iā ʻoe ke hoʻopau me kahi pilina interproximal nui. A no ka mea, he ʻāpana lahilahi ka papillae i paʻi ʻia, he maʻalahi loa ka ʻike ʻana i ka hui ʻana o nā niho, me ke ʻano kūlohelohe.
Manaʻo ʻo Wainright no kāna ʻenehana niho aesthetic mua, hiki i nā mea hoʻohana ke hoʻomalu i ka hohonu o ke komo ʻana o ka niho a me ke kihi e hele mai ai a i waho paha, ma ka hoʻohana ʻana i kahi hana hou i ka polokalamu 3Shape Dental System CAD (version 2018+). Kapa ʻia ke koho i ka hui hui, a hāʻawi i ka mea hoʻohana i ka mana ʻoi aku ka maikaʻi ma mua o ka wā ma mua, kahi mea e hiki mai ana me ka maʻalahi me ka noʻonoʻo ʻana "ʻo ka lōʻihi o ka subgingival o ka niho, ʻoi aku ka ikaika o ka paʻa me ke kumu."
"ʻO ke kumu i ʻokoʻa ai nā niho niho paʻi 3D ma mua o nā niho kuʻuna i hana ʻia, ʻo ia ka resins no ke kumu a me nā niho e like me nā hoahānau. Ke puka mai nā ʻāpana mai loko mai o ka mīkini paʻi a holoi ʻoe iā lākou, ua aneane palupalu a pipili, no ka mea, ua ho'ōla ʻia lākou ma waena o 25 a 35 pakeneka. Akā i ke kaʻina hana hoʻōla UV hope loa, lilo ka niho a me ke kumu i hoʻokahi ʻāpana paʻa.
ʻO ka ʻoiaʻiʻo, ua hōʻike ka loea dentures e hoʻōla nā mea hoʻohana i ke kumu i hui ʻia a me nā niho me kahi kukui hoʻōla UV lima lima, e neʻe ana i loko, e hoʻopaʻa pono i nā ʻāpana. Ke nānā ka mea hoʻohana ua hoʻopiha ʻia nā lua a pau a wehe i ke koena kumu resin, ua piha ka niho niho a mākaukau e hoʻokomo ʻia no 30 mau minuke i ka glycerine ma 80 degere celsius, no ka hola holoʻokoʻa o ka manawa hoʻōla. I kēlā manawa, hiki ke hoʻopau ʻia ka ʻāpana me ka UV glaze a i ʻole ka huila no kahi polish ʻālohilohi kiʻekiʻe.
ʻO ka lua o ka ʻenehana niho niho aesthetic i manaʻo ʻia, ʻo ia ka maʻalahi o ka hoʻopaʻa ʻana me ka ʻole o ka interproximal nui.
Ua wehewehe ʻo Wainright ua hoʻonohonoho ʻo ia i "kēia mau hihia ma CAD no laila ua 100% splinted lākou no ka mea ʻoi aku ka maʻalahi o ka hoʻokomo ʻana i nā niho, ma mua o ka hana ʻana i kēlā me kēia mea hiki ke hoʻoikaika i ka hana. ʻO kaʻu mua e hoʻokuʻu aku i ka arch splinted, akā ʻo ka nīnau ma ʻaneʻi pehea e hana ai i ka pilina ma waena o nā niho interproximally e nānā kūlohelohe, ʻoi aku ka nui inā loaʻa iā ʻoe kahi papilla lahilahi.

Kōkua maoli kēia i ka nani o ka niho niho me ka hopohopo ʻole i nā wahi āpau.
Manaʻo pū ʻo ia i ka wā o ke kaʻina hana, hiki i nā mea hoʻohana ke palaki maʻalahi i ka resin gingiva ma nā ākea e ʻike pono ʻaʻohe ea, nā āpau a i ʻole nā waha, e mālama ana i ka ikaika.
"E mālama i kou maka no nā ʻōhū," wahi a Wainright i nā manawa he nui, me ka wehewehe ʻana "inā ʻoe e hana liʻiliʻi i ka loaʻa ʻana o ka resin i loko o nā hakahaka, e hōʻemi maoli ia i nā ʻōhū."
Ua hoʻohui pū ʻo ia ʻo ke kī ʻo ia ka "holo ʻoi aku i ka resin ma mua, ma kahi o ka pulu wale ʻana, a i ka wā e ʻomi ʻia ai e kahe ana i kēlā wahi. ʻO ka hope, hiki ke holoi ʻia ke kahe me ka manamana lima lima. "
“Me he mea maʻalahi loa ia akā ʻo kēia nā mea a mākou e aʻo ai i ka manawa. Ua hana hou au i ka nui o kēia mau kaʻina hana i kekahi mau manawa a ua ʻoi aku ka maikaʻi, i kēia lā hiki iaʻu a hiki i 10 mau minuke i ka nui loa e hoʻopau i hoʻokahi niho niho. Eia kekahi, inā ʻoe e noʻonoʻo e pili ana i nā kākoʻo paʻi palupalu i ka Form 3, e ʻoi aku ka maʻalahi o ka hoʻoponopono ʻana, no ka mea hiki i kekahi ke ʻoki iā lākou a hoʻohui i ka hoʻopau liʻiliʻi loa i ka huahana.
No ke ʻano hana hoʻonaʻauao maikaʻi hope loa, ua ʻōlelo ʻo Wainwright e hahai i ka laʻana "nā niho niho Brazil", e hāʻawi ana i kahi ala hoʻoikaika e hana ai i ka gingiva e like me ke ola. Ua ʻōlelo ʻo ia ua ʻike ʻo ia ua lilo ka poʻe Brazil i poʻe loea i ka hana ʻana i nā niho niho, me ka hoʻohui ʻana i nā resins translucent i loko o ke kumu e hiki ai i ka maʻi ke ʻike i ke kala gingiva ponoʻī. Ua manaʻo ʻo ia he translucent ka resin Formlabs resin, akā i ka hoʻāʻo ʻia ʻana ma ke kumu hoʻohālike a i ʻole ka waha o ka mea maʻi, "hoʻohui ia i kahi hohonu maikaʻi i ka gingiva ponoʻī e hāʻawi ana i ka noʻonoʻo o ka mālamalama pono i ka aesthetics."
"I ka wā e noho ai ka niho niho i loko o ka waha, ʻike ʻia ka gingiva maoli o ka mea maʻi ma o ka hoʻōla ʻana i ka prosthetic."
Ua ʻike ʻia ʻo Formlabs no ka hoʻokumu ʻana i nā ʻōnaehana paʻi 3D hilinaʻi a hiki i nā poʻe loea. Wahi a ka hui, i nā makahiki he ʻumi i hala iho nei, ua lilo ka mākeke niho i ʻāpana nui o ka ʻoihana o ka hui a ua hilinaʻi ʻia ʻo Formlabs e nā alakaʻi ʻoihana niho ma ka honua holoʻokoʻa, "e hāʻawi ana ma luna o 75 kākoʻo a me nā limahana lawelawe a ʻoi aku ma mua o 150 mau ʻenekinia."
