Anthu opitilira 36 miliyoni aku America alibe mano, ndipo anthu 120 miliyoni ku US akusowa dzino limodzi. Ndi ziwerengerozi zikuyembekezeka kukula muzaka makumi awiri zikubwerazi, msika wamano osindikizidwa a 3D ukuyembekezeka kukula kwambiri.

Sam Wainwright, Woyang'anira Dental Product ku Formlabs, adanenanso pawebusayiti yaposachedwa ya kampaniyo kuti "sadabwe kuwona 40% ya mano ku America opangidwa ndi kusindikiza kwa 3D," ponena kuti ndizomveka "paukadaulo chifukwa pali. palibe kutaya zinthu.” Katswiriyu adafufuza njira zina zomwe zatsimikizira kuti zimagwira ntchito bwino pamano osindikizidwa a 3D. Webinar, yotchedwa Can 3D printed dentures look good?, Anapereka madokotala, akatswiri, ndi aliyense amene akufuna kugwiritsa ntchito 3D yosindikiza kuti akonze mano opangira mano, malangizo amomwe mungachepetsere ndalama zakuthupi ndi 80% (poyerekeza ndi makhadi achikhalidwe ndi acrylic); tsatirani masitepe ochepa kuti mupeze zotsatira zabwino kwambiri, komanso kuteteza mano kuti asawonekere mwachibadwa.

“Uwu ndi msika womwe ukukulirakulira wokhala ndi zosankha zambiri. Ma mano osindikizidwa a 3D ndi chinthu chatsopano kwambiri, makamaka kwa ma prosthetics ochotsedwa (chinachake chomwe sichinakhalepo pa digito) kotero zitenga nthawi kuti ma lab, madokotala ndi odwala azolowera. Nkhaniyi ikuwonetsedwa kuti igwiritsidwe ntchito kwa nthawi yayitali koma kutengera kofulumira kwambiri kwaukadaulo kudzakhala kutembenuka kwachangu komanso mano akanthawi, omwe ali ndi chiopsezo chochepa chomwe chimalola akatswiri a mano kuyenda osathamangira muukadaulo watsopanowu. Tikuyembekezanso kuti utomoni udzakhala wabwino, wamphamvu komanso wokongola pakapita nthawi, "atero Wainwright.

M'malo mwake, m'chaka chatha, Formlabs adakwanitsa kale kukweza ma resin omwe amagulitsa kwa akatswiri azachipatala kuti apange ma prostheses amkamwa, otchedwa Digital Dentures. Ma resin ovomerezedwa ndi FDA atsopanowa samangofanana ndi mano achikhalidwe komanso ndi otsika mtengo kuposa njira zina. Pa $299 ya mano opangira mano ndi $399 ya utomoni wa mano, kampaniyo ikuganiza kuti mtengo wonse wa utomoni wa mano a mano ndi $7.20. Kuphatikiza apo, Formlabs adatulutsanso chosindikizira chatsopano cha Fomu 3, chomwe chimagwiritsa ntchito zolumikizira zopepuka: kutanthauza kuti kukonzanso kwakhala kosavuta. Kuchotsa thandizo kudzakhala kwachangu pa Fomu 3 kuposa Fomu 2, zomwe zikutanthauza kutsika mtengo wazinthu ndi nthawi.

"Tikuyesera kuletsa mano kuti asamawoneke ngati achilendo, ndipo nthawi zina ndi mano osindikizidwa a 3D awa, kukongola kumakhala kovuta kwambiri. Timakonda kuganiza kuti mano ayenera kukhala ndi moyo ngati gingiva, m'mphepete mwachibelekero chachilengedwe, mano akuyang'ana payekha, komanso kukhala osavuta kusonkhanitsa, "adatero Wainright.

Mayendedwe ofunikira a Wainright ndikutsata kachitidwe kakale mpaka zitsanzo zomaliza zitatsanuliridwa ndikufotokozedwa ndi sera, zomwe zimafunika kukhala zadigito ndi makina apakompyuta a 3D scanner omwe amalola kupanga digito mu mano aliwonse otseguka a CAD. dongosolo, kutsatiridwa ndi 3D kusindikiza maziko ndi mano, ndipo potsiriza pambuyo processing, kusonkhanitsa ndi kutsiriza chidutswa.

“Pambuyo popanga ziwalo zambirimbiri, kusindikiza mano ndi maziko ambiri, ndi kuwaphatikiza, tapeza njira zitatu zopangira mano owoneka bwino a 3D osindikizidwa. Zomwe tikufuna ndikupewa zina mwazotsatira za mano amakono amakono, monga mankhwala okhala ndi opaque base kapena gingiva, zomwe ndi zosokoneza pang'ono m'malingaliro mwanga. Kapena mumabwera pafupi ndi semi transluscent base yomwe imasiya mizu poyera, ndipo pomaliza mukamagwiritsa ntchito njira yolumikizira mano mutha kukhala ndi kulumikizana kwakukulu kwapakati. Ndipo popeza kuti papillae ndi tizigawo tating’ono kwambiri tosindikizidwa, nkosavuta kuona mano akulumikizana, ooneka osakhala achibadwa.”

Wainright akusonyeza kuti pa njira yake yoyamba yokongoletsera mano, ogwiritsa ntchito amatha kulamulira kuya kwa dzinolo komanso mbali yomwe imalowa kapena kutuluka, pogwiritsa ntchito ntchito yatsopano mu pulogalamu ya 3Shape Dental System CAD (mtundu wa 2018 +). Njirayi imatchedwa coupling mechanism, ndipo imapatsa wogwiritsa ntchito mphamvu zambiri kuposa kale, chinthu chomwe chimakhala chothandiza kwambiri poganizira kuti "dzino likakhala lalitali kwambiri, limakhala lolimba kwambiri ndi maziko ake."

"Chifukwa chomwe mano osindikizira a 3D ndi osiyana ndi omwe amapangidwa kale ndikuti ma resin apansi ndi mano ali ngati azisuweni. Ziwalo zikatuluka mu chosindikizira ndikuzitsuka, zimakhala zofewa komanso zomata, chifukwa zimangochiritsidwa pang'ono, pakati pa 25 ndi 35 peresenti. Koma pomaliza kuchiritsa kwa UV, dzino ndi maziko ake zimakhala gawo limodzi lolimba. ”

M'malo mwake, katswiri wa mano akuwonetsa kuti ogwiritsa ntchito ayenera kuchiza maziko ophatikizika ndi mano ndi nyali yapamanja ya UV yochizira, kulowera mkati, kuti angogwirizanitsa ziwalozo. Wogwiritsa ntchito akayang'ana kuti zibowo zonse zadzazidwa ndikuchotsa utomoni wotsalira, mano a mano amatha ndipo ali okonzeka kumizidwa kwa mphindi 30 mu glycerine pa madigiri 80 Celsius, kwa ola lathunthu lachirengedwe. Panthawi imeneyo, chidutswacho chikhoza kumalizidwa ndi kuwala kwa UV kapena gudumu kuti likhale lowala kwambiri.

Njira yachiwiri yopangira mano okongoletsa imaphatikizapo kusakanikirana kosavuta kolumikizana popanda bulky interproximal.

Wainright anafotokoza kuti amakhazikitsa "milanduyi ku CAD kotero kuti 100% imagawanika palimodzi chifukwa n'zosavuta kukhala ndi malo okhazikika a mano, m'malo mochita chimodzi ndi chimodzi chomwe chingakhale chovuta kwambiri. Choyamba ndimatumiza kunja chipilalacho chogawanika, koma funso ili ndi momwe mungapangire kulumikizana pakati pa mano molumikizana bwino, makamaka mukakhala ndi papilla woonda kwambiri. Chifukwa chake tisanasonkhanitse, panthawi yochotsa chithandizo, titenga diski yodula ndikuchepetsa kulumikizana kwapakati kuchokera pamphepete mwa khomo lachiberekero kupita ku incisal. Izi zimathandizadi kukongola kwa mano popanda kuda nkhawa ndi malo aliwonse. ”

Amalimbikitsanso kuti pa nthawi ya msonkhano, ogwiritsa ntchito amatha kutsuka mosavuta mu utomoni wa gingiva m'mipata kuti atsimikizire kuti palibe mpweya, mipata kapena voids, kusunga mphamvu.

"Yang'anirani ming'oma," Wainright anabwereza nthawi zambiri, kufotokoza kuti "ngati mutalumikizana pang'ono kuti mutenge utomoni m'mipata, imachepetsa kwambiri thovu."

Anawonjezeranso kuti chinsinsi chake ndi “kutuluka mu utomoni wochuluka poyamba, m’malo mongonyowetsa, ndipo ukaupanikiza umalowa m’dera limenelo. Potsirizira pake, kusefukirako kukhoza kuchotsedwa ndi chala chotchinga.”

"Zikuwoneka zosavuta koma izi ndi zomwe timaphunzira pakapita nthawi. Ndidabwereza zambiri mwazinthu izi kangapo ndipo ndidakhala bwino, lero zinganditengere mphindi 10 kuti ndimalize kupanga mano amodzi. Komanso, ngati mungaganizire za kukhudza kofewa mu Fomu 3, kukonza positi kudzakhala kosavuta, chifukwa aliyense atha kuzing'amba ndikuwonjezera kumalizidwa pang'ono pachogulitsacho. ”

Paupangiri womaliza wa mano okongoletsa, Wainwright adapereka lingaliro lotsatira chitsanzo cha "ma mano a ku Brazil", chomwe chimapereka njira yolimbikitsa yopangira gingiva ngati moyo. Akuti adazindikira kuti anthu aku Brazil akhala akatswiri popanga mano, ndikuwonjezera ma resin owoneka bwino m'munsi omwe amalola kuti mtundu wa gingiva wa wodwalayo uwonekere. Anati utomoni wa LP utomoni wa Formlabs umakhala wowoneka bwino, koma ukayesedwa pa chitsanzo kapena pakamwa pa wodwala, "zimawonjezera kuya kwabwino kwa gingiva yomwe imapereka chithunzithunzi cha kuwala kothandiza mu kukongola."

Dongosolo la mano likamakhala m'mphuno, nsonga yachibadwa ya wodwalayo imaonekera pochititsa kuti manowo akhale amoyo."

Ma Formlabs amadziwika popanga makina osindikizira odalirika a 3D kwa akatswiri. Malinga ndi kampaniyo, m'zaka khumi zapitazi, msika wamano wakhala gawo lalikulu labizinesi yakampaniyo komanso kuti Formlabs imadaliridwa ndi atsogoleri amakampani amano padziko lonse lapansi, "akupereka othandizira opitilira 75 ndi ogwira ntchito ndi akatswiri opitilira 150."

Yatumiza osindikiza opitilira 50,000 padziko lonse lapansi, ndi akatswiri a mano masauzande ambiri akugwiritsa ntchito Fomu 2 kukonza miyoyo ya odwala masauzande ambiri. Kuonjezera apo, kugwiritsa ntchito zipangizo zawo ndi osindikiza mu maopaleshoni oposa 175,000, 35,000 splints ndi 1,750,000 3D osindikizidwa mbali za mano. Chimodzi mwa zolinga za Formlabs ndikukulitsa mwayi wopeza digito, kuti aliyense athe kupanga chilichonse, ichi ndi chimodzi mwa zifukwa zomwe kampaniyo ikupanga ma webinars, kuthandiza aliyense kufika kumeneko.

Wainright adawululanso kuti Formlabs idzatulutsa maziko awiri atsopano a mano, RP (pinki yofiira) ndi DP (pinki yakuda), komanso mawonekedwe awiri atsopano a mano a mano, A3 ndi B2, omwe adzagwirizane ndi A1, A2, A3 yomwe ilipo kale. 5 ndi b1.
