Ntau tshaj 36 lab tus neeg Amelikas tsis muaj hniav, thiab 120 lab tus tib neeg hauv Asmeskas tau ploj lawm tsawg kawg yog ib tus hniav. Nrog rau cov lej no xav tias yuav loj hlob nyob rau hauv ob xyoos tom ntej no, kev ua lag luam rau 3D luam ntawv hniav nyiaj hniav kub yuav tsum loj hlob.

Sam Wainwright, Tus Thawj Saib Xyuas Kev Kho Hniav ntawm Formlabs, tau tawm tswv yim thaum lub tuam txhab kev tshaj tawm webinar tias nws yuav tsis xav tsis thoob thaum pom 40% ntawm cov hniav nyiaj hniav kub hauv Asmeskas ua nrog 3D luam ntawv, "hais tias nws ua rau kev nkag siab "ntawm qib thev naus laus zis vim tias muaj tsis poob ntawm cov khoom. " Tus kws tshaj lij delved rau hauv qee cov txheej txheem uas tau ua pov thawj los ua haujlwm kom zoo nkauj zoo nkauj 3D luam ntawv hniav hniav. Lub webinar, hu ua 3D luam ntawv hniav hniav zoo li zoo?, muab cov kws kho hniav, kws kho hniav, thiab leej twg xav siv 3D luam ntawv los txhim kho hniav hniav, cov lus qhia txog yuav ua li cas txiav cov nqi ntawm cov khoom mus txog 80% (piv rau cov hniav nyiaj hniav kub thiab acrylic); ua cov kauj ruam tsawg dua kom tau txais cov txiaj ntsig zoo, thiab tag nrho tiv thaiv cov hniav los ntawm qhov tsis zoo.

"Qhov no yog ib qho kev lag luam nthuav dav nrog ntau txoj kev xaiv. 3D luam ntawv hniav hniav yog ib yam tshiab heev, tshwj xeeb tshaj yog rau tshem tawm prosthetics (ib yam dab tsi uas tsis tau ua digitalized) yog li nws yuav siv sij hawm ib co sij hawm rau cov chaw kuaj mob, kws kho hniav thiab cov neeg mob siv rau nws. Cov khoom siv tau qhia rau kev siv mus sij hawm ntev tab sis qhov kev saws me nyuam sai tshaj plaws ntawm cov cuab yeej no yuav yog kev hloov pauv tam sim ntawd thiab kev kho hniav ib ntus, uas muaj kev pheej hmoo tsawg dua uas tso cai rau cov kws kho hniav taug kev tsis tau khiav mus rau hauv cov cuab yeej tshiab no. Peb kuj cia siab tias cov resins tau zoo dua, muaj zog thiab zoo nkauj dua nyob rau lub sijhawm, "said Wainwright.

Qhov tseeb, xyoo tas los, Formlabs twb tau tswj hwm los txhim kho cov resins uas nws muag rau cov kws kho mob los ua qhov ncauj prostheses, hu ua Digital Dentures. Cov ntaub ntawv tshiab uas tau pom zoo los ntawm FDA tsis tsuas yog zoo li cov hniav cuav xwb tab sis lawv kuj pheej yig dua li lwm cov kev xaiv. Ntawm $ 299 rau cov hniav nyiaj hniav kub thiab $ 399 rau cov hniav nyiaj hniav kub, lub tuam txhab kwv yees tias tag nrho cov nqi resin rau cov hniav maxillary yog $ 7.20. Ntxiv mus, Formlabs kuj tsis ntev los no tau tso tawm Daim Ntawv 3 lub tshuab luam ntawv tshiab, uas siv lub teeb kov txhawb nqa: lub ntsiab lus tom qab ua tiav tsuas yog yooj yim dua. Kev tshem tawm kev txhawb nqa yuav ua sai dua ntawm Daim Ntawv 3 dua li Daim Ntawv 2, uas txhais tau tias tsawg dua cov khoom siv thiab sijhawm.

"Peb tab tom sim tiv thaiv cov hniav los ntawm qhov tsis zoo, thiab qee zaum nrog cov hniav 3D luam tawm, qhov zoo nkauj tau raug kev txom nyem los ntawm nws. Peb nyiam xav tias cov hniav hniav yuav tsum muaj lub neej zoo li gingiva, lub ncauj tsev menyuam hauv plab, ib tus neeg saib cov hniav, thiab yooj yim sib sau ua ke, "Wainright tau hais.

Qhov kev ua haujlwm yooj yim uas tau hais los ntawm Wainright yog ua raws li kev ua haujlwm ib txwm ua kom txog rau thaum cov qauv kawg tau nchuav thiab hais tawm nrog wax rim, qhov kev teeb tsa yuav tsum tau ua digital nrog lub desktop kho hniav 3D scanner tso cai rau cov qauv digital hauv txhua qhov qhib CAD kho hniav. system, ua raws li 3D luam ntawv lub hauv paus thiab cov hniav, thiab thaum kawg tom qab ua tiav, sib dhos thiab ua tiav cov khoom.

"Tom qab ua ntau yam, luam tawm ib tuj ntawm cov hniav nyiaj hniav kub thiab cov hauv paus, thiab sib sau ua ke, peb tau los nrog peb cov txheej txheem rau kev zoo nkauj 3D luam ntawv hniav hniav. Qhov peb xav tau yog kom tsis txhob muaj qee qhov tshwm sim ntawm cov hniav nyiaj hniav kub niaj hnub no, xws li cov khoom lag luam nrog lub hauv paus opaque lossis gingiva, uas yog me ntsis ntawm kuv lub tswv yim. Los yog koj tuaj txog ntawm lub hauv paus semi transluscent uas tawm hauv cov hauv paus hniav nthuav tawm, thiab thaum kawg thaum koj siv cov hniav txhuam hniav koj tuaj yeem xaus nrog kev sib txuas loj heev. Thiab txij li cov papillae yog cov ntawv luam tawm tiag tiag, nws yooj yim heev kom pom cov hniav sib txuas, saib tsis zoo. "

Wainright qhia tias rau nws thawj cov txheej txheem kho hniav zoo nkauj, cov neeg siv tuaj yeem tswj qhov tob ntawm kev nkag mus ntawm cov hniav nrog rau lub kaum sab xis uas nws los hauv lossis tawm mus, los ntawm kev siv cov haujlwm tshiab hauv 3Shape Dental System CAD software (version 2018+). Qhov kev xaiv yog hu ua coupling mechanism, thiab muab rau tus neeg siv ntau yam kev tswj ntau dua li ua ntej, ib yam dab tsi uas los nyob rau hauv ke heev xav tias "qhov ntau subgingival ntev ntawm cov hniav muaj, lub zog ntawm daim ntawv cog lus nrog lub hauv paus."

"Qhov laj thawj yog vim li cas 3D luam cov hniav cuav txawv dua li cov hniav cuav uas niaj hnub ua yog cov resins rau hauv paus thiab cov hniav zoo li cov kwv tij txheeb ze. Thaum cov khoom tawm ntawm lub tshuab luam ntawv thiab koj ntxuav lawv, lawv yuav luag mos thiab txawm tias nplaum, vim tias lawv tsuas yog kho tau ib nrab, ntawm 25 thiab 35 feem pua. Tab sis thaum lub sij hawm kawg UV curing txheej txheem, cov hniav thiab lub hauv paus ua ib qho khoom. "

Qhov tseeb, tus kws kho hniav tshwj xeeb qhia tau hais tias cov neeg siv yuav tsum kho cov hauv paus thiab cov hniav nrog ib lub teeb UV kho lub teeb, txav mus rau sab hauv, tsuas yog tuav cov khoom ua ke. Thaum tus neeg siv tau kuaj xyuas tias tag nrho cov kab noj hniav tau sau thiab tshem tawm cov khoom seem seem, cov hniav ntxuav hniav dawb ua tiav thiab npaj txhij rau submerged rau 30 feeb hauv glycerine ntawm 80 degrees celsius, rau tag nrho cov sij hawm kho. Thaum lub sijhawm ntawd, cov khoom tuaj yeem ua tiav nrog UV glaze lossis lub log rau lub siab ci ntsa iab.

Qhov thib ob pom zoo cov txheej txheem kho hniav zoo nkauj yuav tsum muaj qhov sib dhos yooj yim ntawm kev sib dhos yam tsis muaj qhov loj me me.

Wainright tau piav qhia tias nws tau teeb tsa "cov xwm txheej no hauv CAD yog li lawv tau 100% splinted ua ke vim tias nws yooj yim dua kom muaj cov hniav zoo ib yam, tsis yog ua ib qho los ntawm ib qho uas tuaj yeem ua haujlwm hnyav. Kuv thawj zaug xa tawm lub koov splinted, tab sis cov lus nug ntawm no yog yuav ua li cas kom muaj kev sib txuas ntawm cov hniav interproximally zoo, tshwj xeeb tshaj yog thaum koj muaj papilla nyias heev. Yog li ua ntej kev sib dhos, thaum peb tshem tawm ib feem ntawm cov txheej txheem, peb yuav muab cov txiav txiav thiab txo cov kev sib txuas sib txuas los ntawm lub ncauj tsev menyuam mus rau qhov incisal. Qhov no yeej pab tau qhov zoo nkauj ntawm cov hniav hniav yam tsis muaj kev txhawj xeeb txog qhov chaw. "

Nws kuj pom zoo tias thaum lub sij hawm sib dhos txheej txheem, cov neeg siv tau yooj yim txhuam hauv gingiva resin hauv qhov chaw kom paub tseeb tias tsis muaj cua, qhov khoob lossis qhov khoob, tuav lub zog.

"Ua kom koj lub qhov muag tawm ntawm cov npuas," Wainright tau rov hais dua ntau zaus, piav qhia tias "yog tias koj ua haujlwm tsawg kawg nkaus kom tau cov resin nyob rau hauv qhov chaw, nws yeej txo cov npuas."

Nws kuj tau hais ntxiv tias tus yuam sij yog "khiav hauv ntau cov resin thaum xub thawj, tsis yog tsuas yog ntub nws, thiab thaum nws tau nyem ua ke nws yuav ntws mus rau hauv cheeb tsam ntawd. Thaum kawg, cov dej ntws tuaj yeem raug muab tshem tawm nrog ib tus ntiv tes looj tes. "

"Nws zoo li yooj yim heev tab sis qhov no yog yam peb kawm dhau sijhawm. Kuv rov ua ntau yam ntawm cov txheej txheem no ib zaug ib zaug thiab tau zoo dua, hnub no nws yuav siv sij hawm kuv mus txog 10 feeb ntawm feem ntau kom tiav ib qho hniav. Ntxiv mus, yog tias koj xav txog qhov kev txhawb nqa muag muag hauv Daim Ntawv 3, kev ua haujlwm tom qab yuav yooj yim dua, vim tias leej twg yuav muaj peev xwm rub lawv tawm thiab ntxiv me ntsis ua tiav rau cov khoom. "

Rau cov txheej txheem kho hniav zoo nkauj kawg, Wainwright tau tawm tswv yim ua raws li "Brazilian hniav hniav" piv txwv, uas muaj kev txhawb siab los tsim lub neej zoo li gingiva. Nws hais tias nws pom cov neeg Brazilians tau dhau los ua cov kws tshaj lij hauv kev tsim cov hniav hniav, ntxiv cov pob zeb zoo nkauj hauv lub hauv paus uas tso cai rau tus neeg mob tus kheej cov gingiva xim los qhia. Nws tau hais tias LP resin Formlabs resin kuj yog qhov zoo nkauj heev, tab sis thaum kuaj ntawm tus qauv lossis tus neeg mob lub qhov ncauj, "nws ntxiv qhov tob zoo rau cov gingiva nws tus kheej muab qhov kev xav ntawm lub teeb muaj txiaj ntsig zoo hauv kev zoo nkauj."

"Thaum cov hniav cuav zaum hauv qhov ncauj, tus neeg mob lub gingiva ntuj qhia los ntawm kev ua kom cov hniav tuaj yeem ua rau muaj sia."

Formlabs paub txog kev tsim kev txhim khu kev qha, siv tau 3D tshuab luam ntawv rau cov kws tshaj lij. Raws li lub tuam txhab, nyob rau hauv kaum xyoo dhau los, kev lag luam kho hniav tau dhau los ua ib feem ntawm lub tuam txhab kev lag luam thiab Formlabs ntseeg tau los ntawm cov thawj coj kev lag luam kho hniav thoob plaws ntiaj teb, "muab ntau tshaj 75 tus neeg ua haujlwm txhawb nqa thiab kev pabcuam thiab ntau tshaj 150 engineers."

Nws tau xa tawm ntau dua 50,000 lub tshuab luam ntawv thoob ntiaj teb, nrog ntau txhiab tus kws kho hniav siv daim ntawv 2 los txhim kho lub neej ntawm ntau pua txhiab tus neeg mob. Tsis tas li ntawd, siv lawv cov ntaub ntawv thiab cov tshuab luam ntawv hauv ntau dua 175,000 kev phais, 35,000 splints thiab 1,750,000 3D luam ntawv kho hniav. Ib qho ntawm lub hom phiaj ntawm Formlabs yog txhawm rau nthuav dav kev nkag mus rau digital fabrication, yog li leej twg tuaj yeem ua txhua yam, qhov no yog ib qho laj thawj vim li cas lub tuam txhab tab tom ua webinars, pab txhua tus mus txog ntawd.

Wainright kuj tau tshaj tawm tias Formlabs yuav tshaj tawm ob lub hauv paus hniav hniav tshiab, RP (liab liab liab) thiab DP (dub liab), nrog rau ob lub hniav hniav tshiab, A3 thiab B2, uas yuav ntxiv rau A1, A2, A3 uas twb muaj lawm. 5, ib b1.
