Vanopfuura 36 miriyoni vekuAmerica havana mazino, uye 120 miriyoni vanhu muUS vari kushaya kanenge zino rimwe chete.Nenhamba idzi dzinotarisirwa kukura mumakumi maviri emakore anotevera, musika we3D akadhindwa dentures unotarisirwa kukura zvakanyanya.

Sam Wainwright, Dental Product Manager kuFormlabs, akataura panguva yekambani ichangoburwa webinar kuti "haaizoshamisika kuona makumi mana muzana emazino muAmerica achigadzirwa nekudhindwa kwe3D," achiti zvine musoro "padanho retekinoroji nekuti pane. hapana kurasikirwa nezvinhu.”Nyanzvi yakanyura mune dzimwe nzira dzakaratidza kushanda kune aesthetically zviri nani 3D akadhindwa mazino emazino.Webinar, yakanzi Can 3D akadhindwa mazino emazino anotaridzika zvakanaka?, akapa vanachiremba vemazino, nyanzvi, uye chero ani zvake anofarira kushandisa 3D kudhinda kuvandudza mazino, matipi ekuti ungacheka sei mitengo yezvinhu kusvika 80% (zvichienzaniswa nemakadhi emazino echinyakare uye acrylic);ita matanho mashoma kuti uwane mibairo yemhando yepamusoro, uye kudzivirira mazino kuti asatarise asiri emusikirwo.

“Uyu musika unogara uchikura une sarudzo dzakawanda.3D akadhindwa mazino emazino chinhu chitsva kwazvo, kunyanya cheanobvisika prosthetics (chimwe chinhu chisina kumbobvira chaitwa digitalized) saka zvichatora nguva kuti maLab, vanachiremba vemazino uye varwere vajairane nazvo.Nyaya yacho inoratidzwa kuti ishandiswe kwenguva refu asi iyo yakanyanya kukurumidza kugashira tekinoroji iyi ichave yekutendeuka nekukasira uye mazino epanguva, ane njodzi yakaderera inobvumira nyanzvi dzemazino kufamba kwete kumhanya mune iyi tekinoroji nyowani.Isu tinotarisirawo kuti marezeni ave nani, akasimba uye anowedzera kunaka munguva, "akadaro Wainwright.

Sezvineiwo, mugore rapfuura, Formlabs yakatokwanisa kukwidziridza marezi ainotengesera vana chiremba kuti vagadzire maoral prostheses, anonzi Digital Dentures.Aya matsva akatenderwa neFDA maresin haangofana nemazino echinyakare asi zvakare akachipa pane dzimwe sarudzo.Pamadhora mazana maviri nemakumi mapfumbamwe nemapfumbamwe edenture base resin uye $399 yemazino resin, kambani inofungidzira kuti iyo yakazara resin mutengo wemazino emazino maxillary i$7.20.Uyezve, Formlabs zvakare ichangobva kuburitsa iyo nyowani yeFomu 3 printer, iyo inoshandisa mwenje wekubata zvitsigiro: zvichireva kuti post-kugadzirisa zvangove nyore.Kubviswa kwerutsigiro kuchaita nekukurumidza paFomu 3 pane yeFomu 2, iyo inoturikira kune mashoma mutengo wemidziyo nenguva.

“Tiri kuyedza kudzivirira mazino kuti asatarise asiri echisikigo, uye dzimwe nguva neaya akadhindwa e3D mazino, aesthetics ari kutambura nazvo.Tinoda kufunga kuti mazino emazino anofanirwa kuva nehupenyu-hwakaita gingiva, mazamu echibereki chechisikigo, munhu anotarisa-mazino, uye ave nyore kuunganidza, "Wainright akadaro.

Iyo general basic workflow inokurudzirwa naWainright ndeyekutevera mafambiro echinyakare kusvika mamodheru ekupedzisira adirwa uye ataurwa newakisi rim, iyo set-up inoda kuitwa dhijitari ine desktop yemazino 3D scanner inobvumira dhizaini yedhijitari mune chero yakavhurika CAD mazino. system, inoteverwa ne 3D kudhinda chigadziko nemeno, uye pakupedzisira post-kugadzirisa, kuunganidza uye kupedzisa chidimbu.

“Mushure mekugadzira zvidimbu zvakawanda, kudhinda toni yemazino emazino nemabhesi, nekuzvibatanidza, tauya nehunyanzvi hutatu hwekunakisa 3D yakadhindwa mazino.Chatinoda ndechekudzivirira zvimwe zvinobuda pamazino edhijitari anhasi, senge zvigadzirwa zvine opaque base kana gingiva, zvinova zvinokanganisa mumaonero angu.Kana kuti iwe unouya nezve semi transluscent base iyo inosiya midzi pachena, uye chekupedzisira kana iwe ukashandisa splinted mazino workflow unogona kupedzisira uine bulky interproximal connection.Uye sezvo papillae ari zvikamu zvitete zvakadhindwa, zviri nyore chaizvo kuona mazino achibatana, achiratidzika seasiri emusikirwo.”

Wainright anoratidza kuti kune yake yekutanga aesthetic dental technique, vashandisi vanogona kudzora kudzika kwekupinda kwezino pamwe chete nekona yainopinda kana kubuda, nekushandisa basa idzva mu3Shape Dental System CAD software (version 2018+).Sarudzo iyi inonzi coupling mechanism, uye inopa mushandisi kudzora zvakanyanya kupfuura kare, chimwe chinhu chinouya zvine mutsindo tichifunga kuti "kunyanya kureba kwezino, ndiko kusimba kwechisungo nenheyo."

“Chikonzero nei 3D akadhindwa mazino emazino akasiyana neagara achiitwa mazino emazino ndechekuti maresi epasi uye mazino akaita semakunakuna.Kana zvikamu zvichibuda muprinta uye iwe unozvigeza, zvinenge zvakapfava uye zvinonamira, nekuti zvinongorapwa zvishoma, pakati pe25 ne35 muzana.Asi panguva yekupedzisira yekurapa UV, zino nechigadziko zvinova chikamu chakasimba. ”

Muchokwadi, nyanzvi yemazino emazino inoratidza kuti vashandisi vanofanirwa kurapa hwaro hwakasanganiswa nemazino neruvoko rweUV rekurapa mwenje, vachifamba vakananga mukati, kungonyatso kubata zvikamu pamwechete.Kana mushandisi achinge atarisa kuti mhango dzese dzazadzwa uye obvisa chero yasara base resin, denture inokwana uye yakagadzirira kunyudzwa kwemaminetsi makumi matatu muglycerine pa80 degrees celsius, kweawa yakazara yenguva yekupora.Panguva iyoyo, chidimbu chinogona kupedzwa kumusoro neUV glaze kana vhiri rekupenya kwakanyanya.

Yechipiri inokurudzirwa aesthetic denture tekinoroji inosanganisira yakatsemuka arch kurerutsa kwekusangana pasina bulky interproximal.

Wainright akatsanangura kuti anogadza "nyaya idzi dziri muCAD kuitira kuti 100% dzakaparadzana pamwe chete nokuti zviri nyore kwazvo kuva nekugadzika kwemazino, pane kuzviita imwe neimwe inogona kushanda nesimba.Ini ndinotanga kutumira arch yakatsemuka, asi mubvunzo uri pano ndewekuti ungaite sei kubatana pakati pemazino kutaridzika sechisikigo, kunyanya kana uine papilla yakaonda kwazvo.Saka tisati tasangana, panguva yerutsigiro rwedu rwekubvisa chikamu chemaitiro, isu tichatora dhisiki rekucheka todzikisa kubatanidza kudzika kubva kumucheto wekervical kuenda kune incisal.Izvi zvinobatsira chaizvo aesthetics yemazino pasina kunetseka nezve chero nzvimbo. "

Anokurudzirawo kuti panguva yegungano, vashandisi vanogona nyore kukwesha mu gingiva resin munzvimbo kuti vaone kuti hapana mhepo, mapundu kana voids, kuchengetedza simba.

"Chengetedza ziso rako kune mabhuru," akadzokorora Wainright kakawanda, achitsanangura kuti "kana iwe ukaita kudyidzana kushoma kuti utore resin munzvimbo, zvinoderedza mabhuru."

Akawedzerawo kuti chinhu chikuru ndecheku“yerera mune mamwe marara pakutanga, pane kungoinyorovesa, uye kana yasvinwa pamwe chete inoyerera ichipinda munzvimbo iyoyo.Pakupedzisira, kufashukira kunogona kupedzwa nemunwe wakavharwa.”

“Zvinoita sezviri nyore asi izvi ndizvo zvinhu zvatinodzidza nekufamba kwenguva.Ndakadzokorora akawanda eaya maitiro kashoma uye ndikaita zvirinani, nhasi zvinogona kunditorera kusvika maminetsi gumi pakunyanya kupedzisa denture rimwe chete.Zvakare, kana iwe ukafunga nezve kunyorova kwekubata kunotsigira muFomu 3, post post ichave nyore, sezvo chero munhu achakwanisa kuvabvarura uye kuwedzera kushoma kupedzisa kuchigadzirwa. ”

Kune yekupedzisira aesthetic denture tekiniki, Wainwright akakurudzira kutevera muenzaniso we "Brazilian dentures", uyo unopa nzira inokurudzira yekugadzira gingiva yehupenyu.Anoti akaona vanhu vekuBrazil vave nyanzvi mukugadzira mazino, vachiwedzera matranslucent maresin mugadziko anobvumira kuti ruvara rwegingiva rwerwerwe rwemunhu rwuratidze.Akataura kuti LP resin Formlabs resin zvakare inoshanduka, asi kana yakaedzwa pamuenzaniso kana muromo wemurwere, "inowedzera hudzamu hwakanaka kune gingiva pachayo ichipa ratidziro yechiedza chinobatsira mune aesthetics."
