CAD/CAM - Qhov kawg rau kev kuaj hniav lossis pib tshiab?

Cov cuab yeej siv thev naus laus zis lo lus zoo li kev kho hniav tseem ceeb, CAD/CAM, kev tshuaj xyuas sab hauv, kev tshuaj xyuas sab nrauv, 3-D milling, thiab 3-D luam ntawv tau hnov ​​thoob plaws hauv kev lag luam kho hniav. Nws zoo li thaum twg cov kws kho hniav tau koom ua ke nws tsis ntev ua ntej tsawg kawg ib ntawm cov ncauj lus no tau tham.

Yog li nws tsis yog qhov xav tsis thoob uas thaum ze rau 8,000 tus kws tshaj lij kho hniav los ntawm txhua qhov ntawm kev lag luam tau koom ua ke hauv Singapore thaum lub Plaub Hlis rau IDEM Singapore 2014, cov rooj nthuav qhia tau muaj cov ncauj lus no tag nrho. Lawv kuj tau sib tham hauv ntau qhov kev qhuab qhia, tab sis tej zaum lawv feem ntau nyob hauv cov chav qhuab qhia thiab chav so ntawm Dental Technician Forum, ib ntawm peb txoj kab tshiab qhia rau IDEM Singapore.

Thaum txhua tus zoo li pom zoo tias "yav tom ntej yog tam sim no," kuj tseem muaj qee qhov tsis txaus ntseeg thiab txaus ntshai rau yav tom ntej uas tau tsoo lub qhov rooj ntawm Asia lub chaw kuaj hniav thiab phais. Cov lus nug txhawj xeeb qee tus, tshwj xeeb tshaj yog cov laus thiab tsim ntau lab thiab cov kws tshaj lij, puas yog nws tuaj txog tau hnov ​​lub suab tuag ntawm cov tsoos, cov kws tshaj lij-raws cov kws kho hniav thiab ua lag luam rov kho dua, lossis tshaj tawm txoj kev loj hlob uas yuav pom ntau qhov xav tau hauv Asia txoj kev lag luam loj hlob?

Qhov xwm txheej niaj hnub nyob hauv ntau tus kws tshaj lij lub siab yog qhov kev nce qib hauv kev siv tshuab thev naus laus zis, ua ke nrog cov cuab yeej muaj zog thiab muaj peev xwm ntau dua, pub cov qauv 3-D virtual mus rau qhov pheej yig dua thiab raug dua 3-D tshuab luam ntawv, yuav txhais tau tias cov kws kho hniav yuav tuaj yeem tuav lawv tus kheej tsim khoom xav tau.

Raws li cov tuam ntxhab thiab cov xa khoom ntawm ntau yam thev naus laus zis kho hniav, hnub ntawd twb los txog lawm. Lub tshuab muaj peev xwm tso cai rau cov kws kho hniav los tshuaj xyuas cov neeg mob cov hniav thiab tsim cov yas rau cov neeg mob thaum lawv tos. Cov txheej txheem uas ib txwm siv sijhawm ntau lub lis piam, tam sim no tuaj yeem ua tiav hauv ib teev lossis ob teev.

Es tsis txhob ua pwm thiab xa nws mus rau lub chaw kuaj ntshav, tus kws kho hniav zoo tuaj yeem siv ntau yam thev naus laus zis, los ntawm lub koob yees duab sab hauv mus rau CBT, txhawm rau tshuaj xyuas cov hniav ncaj qha. Cov ntawv digitized tuaj yeem xa mus rau qhov chaw milling lossis 3-D tshuab luam ntawv los txiav cov yas los ntawm cov plooj (porcelain) thaiv, lossis luam tawm los ntawm cov yas thaum tus neeg mob so hauv chav tos. Tom qab ua tiav me me thiab npaj ua haujlwm, cov yas tau npaj rau haum, thiab tus neeg mob txaus siab rov qab mus ua haujlwm.

Nov yog qhov xwm txheej uas yuav tsum tau thov rau cov neeg mob - kev mus ntsib ib zaug yam tsis tas yuav taug kev ncig nrog cov yas ib ntus uas ua rau lawv txuag nyiaj nyob rau ob lub sijhawm thiab nyiaj txiag. Hauv txoj kev xav nws txaus siab rau qee tus kws kho hniav ib yam nkaus, raws li lawv pom lub sijhawm los txiav tawm cov pwm thiab tus neeg nruab nrab - tus kws tshaj lij tsis zoo. Tab sis qhov no tseem tsis muaj tseeb?

Cov lus teb luv yog tsis yog. Ib tus tswv chaw kuaj mob lossis kws tshaj lij uas tau poob pw tsaug zog vim qhov poob ntawm lawv txoj kev ua neej nyob tuaj yeem so. Nws tsis yog tias CAD/CAM yuav tsis hloov pauv kev lag luam, nws yeej tau ua qhov ntawd thiab tseem yuav ua txuas ntxiv mus, tab sis nws tsis zoo li nws yuav ua nyob rau hauv txhais tes ntawm kws kho hniav.

Thaum 3-D luam ntawv tseem tshiab, CAD/CAM tsis yog. Hauv Tebchaws Europe, Tebchaws Askiv, thiab Tebchaws Meskas, cov kws kho hniav tau nkag mus rau thev naus laus zis thev naus laus zis, lub zog siv computer, thiab txawm tias lub tshuab milling desktop tau 20 xyoo lossis ntau dua, tabsis lawv tsis tau saws nws ntau. Txawm nyob hauv Asmeskas, lub ntiaj teb loj tshaj plaws thiab tshaj lij tshaj plaws kev kho hniav ua lag luam, tsuas yog qee yam xws li 8% txog 10% ntawm kev phais hniav muaj nyob hauv tsevCAD/CAMfacilities.

Kwv yees li ib ntawm 10 ntawm cov uas tsis siv cov cuab yeej txawm hais tias kev nqis peev nyiaj txiag tseem ceeb, feem ntau vim tias lawv pom txoj kev kawm nkhaus nkhaus dhau los lossis raug tso tawm los ntawm xwm txheej lossis teeb meem kho mob. Feem coob ntawm cov uas siv cov cuab yeej ua li ntawd tsuas yog rau ib qho tom qab crowns, thiab tseem xa qhov nyuaj tom qab thiab txhua txoj haujlwm yav dhau los mus rau lwm qhov chaw sim. Txawm hais tias lossis lawv tau ntiav lawv tus kheej cov kws tshaj lij hauv tsev los siv cov cuab yeej kom muaj peev xwm tag nrho.

Nws tsis zoo li feem ntau ntawm cov kws kho hniav nrog 10 txog 20 xyoo ua ntej so haujlwm yuav txaus siab hloov pauv mus rau cov thev naus laus zis tshiab no. Thaum lawv yuav nyob rau theem ntawm lawv txoj haujlwm uas lawv tuaj yeem them taus, lawv feem ntau raug tshem tawm los ntawm txoj kev kawm txaus ntshai. Raws li ob tus kws tshaj lij hauv ntiaj teb ntawm kev siv CAD/CAM hauv kev kho hniav, cov kws kho hniav Italis cov kwv tij Andrea thiab Alessandro Agnini tau taw qhia thaum lub sijhawm qhuab qhia ntawm IDEM Singapore tias hauv lawv cov kev paub nrog kev tshuaj xyuas sab hauv, feem ntau cov kws kho hniav nrog 20 lossis ntau xyoo kev paub ua haujlwm nrog pwm pom nws nyuaj rau hloov pauv thiab feem ntau nyiam lo nrog qhov lawv paub - pwm.

Cov kws kho hniav tiam tam sim no thiab cov tub ntxhais kawm kho hniav tam sim no tau yooj yim dua nrog cov thev naus laus zis, raws li Cov Kws Kho Mob Agnini tau pom ntawm lawv qhov chaw kawm hauv Ltalis. Cov kws kho hniav cov tub ntxhais kawm uas tsis muaj kev paub dhau los nrog pwm lossis 3-D thev naus laus zis thev naus laus zis nyiam cov txheej txheem tshiab tshaj plaws, thiab lub peev xwm nws muab rau lawv ua haujlwm ze nrog cov kws tshaj lij. Txawm li cas los xij, thaum cov neeg kawm tiav tshiab tau xis nyob nrog cov thev naus laus zis tshiab tshaj plaws thaum pib ntawm lawv txoj haujlwm, lawv tsis zoo li tsis muaj peev los nqis peev hauv cov tsev tsim khoom hauv tsev.

Cov Kws Kho Mob Agnini tsis tuaj yeem xav txog yav tom ntej yam tsis muaj kev txawj ntse, kws tshaj lij txuj ci pab lawv tsim cov cuab yeej kho hniav uas lawv nto npe rau. Hauv lawv qhov kev piav qhia zaum kawg ntawm IDEM Singapore, lawv tau lees paub rau cov neeg mloog ntawm cov kws tshaj lij tias raws li thev naus laus zis thiab cov ntaub ntawv ua ntej thiab ua kom muaj ntau yam thiab kho kom rov zoo dua tuaj yeem ua tau, lub luag haujlwm ntawm tus kws tshaj lij kws tshaj lij txuj ci yuav dhau los ua qhov tseem ceeb hauv kev xa cov txiaj ntsig zoo tshaj plaws rau cov neeg mob.

Dr. Dobrina Mollova ntawm Center for Advanced Professional Practices (CAPP) yeej tsis xav tias thev naus laus zis tuaj yeem hloov pauv cov kws tshaj lij,

"Yuav ib txwm xav tau cov kws tshaj lij, rau cov kws tshaj lij uas yog cov kws tshaj lij hauv kev siv cov tshuab uas ua rau cov kws kho hniav ua hniav uas niaj hnub siv tshuaj kho hniav vam khom," Dr. Mollova hais. "Cov tshuab thiab thev naus laus zis uas lawv siv yuav hloov pauv, tab sis xav tau cov kws tshaj lij los ua haujlwm rau lawv yuav nyob twj ywm. Yog li tsuav yog cov kws kho mob khaws lawv cov txuj ci thiab kev paub txog niaj hnub no, lawv yuav yog ib feem tseem ceeb ntawm pab neeg kho hniav. "

Dr. John Burgess, Tus Pab Thawj Saib Xyuas Kev Tshawb Fawb ntawm Tsev Kawm Qib Siab Alabama, tseem ntseeg tias kev kho hniav digital thiab CAD/CAM sawv cev rau lub sijhawm zoo rau kev kuaj hniav thiab kws tshaj lij. Nws xav tias lub sijhawm no yog lub sijhawm zoo rau cov kws kho hniav thiab cov kws tshaj lij hauv tebchaws Asia, tshwj xeeb yog cov nyob hauv cov tebchaws Esxias yav Qab Teb uas muaj cov neeg kawm nruab nrab tau nthuav dav sai, thiab cov kws kho hniav thiab cov kws kho mob tshiab tau los ua kom tau raws li qhov lawv xav tau. Nws ntseeg hais tias cov neeg Esxias sab hnub tuaj yuav nyob rau hauv txoj haujlwm kom dhau ib tiam lossis ob xyoos ntawm cov cuab yeej siv prosthodontic los coj kev rov ua haujlwm nyob rau hauv kev nyiaj txiag mus txog ntawm kev ua lag luam loj dua li yav tas los tau.
