Kev nce qib hauv cov khoom sib txawv thiab cov ntaub ntawv kho hniav tau hloov maj mam tab sis tsis tu ncua, kev tsim kho kom zoo nkauj, kev tsim kho kom zoo nkauj hauv kev tshawb fawb. Txawm hais tias lub sijhawm twg, kev qhia ntawm cov ntaub ntawv tshiab tau muaj kev cuam tshuam zoo tshaj thev naus laus zis. Kev ua haujlwm ntawm cov tshuaj hnub tim ntawm 3000 BC, nrog rau daim ntawv thov ntawm cov ntaub ntawv ntawm qhov ncauj tawm los ntawm tib lub sijhawm.
Thaum pib
Kev siv ntxov tshaj plaws ntawm cov khoom siv tau tshwm sim hauv 2500 BC. Golden crown bridges tau qhia ntawm 700 thiab 500 bc. Nyob rau hauv lub xyoo 1 AD AD, Roman tus kws tshaj lij cov ntaub ntawv paj rwb, txhuas los sau cov kab noj hniav, yuav sau cov ntaub ntawv ntawm kev kho hniav. Thaum lub sij hawm Tang Dynasty (7 txog 10 xyoo pua AD) hauv Suav teb, nyiaj muab cov khoom siv, muaj nyiaj, mercury, thiab zoo ib yam li niaj hnub amalgam. Nruab nrab ntawm 1050-1122}} cov kab tsuag tau ntim nrog cov lus tsis txaus siab, alum, thiab zib ntab, thaum nyob rau hauv 1480, Italian kws kho hniav Johannes cov teb los ntawm kev siv kub nplooj ua cov khoom siv kub li cov khoom siv kub. Hauv 1548, Walter Herman tau sau thawj daim ntawv qhia txog tus kab ntawm lub qhov ncauj, muaj kev cuam tshuam rau cov ntaub ntawv uas rov qab.
Kev loj hlob sai
Lub xyoo pua 17th tau pom sai sai hauv chemistry thiab physics, ua rau cov kev nce qib tseem ceeb hauv stomatology thaum lub xyoo pua 18th. Ntau daim credit Pierre Foutubeard hnub 1728 tshaj tawm thaum yug ntawm cov kho hniav me me. Nws ua haujlwm duav tau ntau yam ntawm cov txheej txheem sib txawv, suav nrog cov hau kev rau cov khoom siv tes ua khoom siv kos duab los ntawm kaus ntxhw. Xyoo 1756, PFAFAQUE qhia cov txheej txheem rau kev noj hniav nrog siv cov hniav tsawg dua hauv 1770. Nyob rau hauv lub suab kho hniav hauv 1770. Xyoo no nyob rau hauv lub xyoo pua puv 19.
Ntau cov ntaub ntawv thiab cov tswv yim siv niaj hnub no muaj keeb kwm keeb kwm, txawm hais tias kev tshawb fawb keeb kwm tom qab lawv siv tsuas yog tsim hauv cov niaj hnub no. Yav dhau los, kev kho hniav cov txheej txheem feem ntau tau nqa tawm ntawm manually, nrog tus neeg mob lub qhov ncauj ua haujlwm ua thawj lub rooj zaum "."
Mub kev txhim kho
Txoj kev tshawb no ntawm Aminggam nyob rau hauv nruab nrab -19 koj lub xyoo pua ua rau cov ntaub ntawv sciental, nrog ceramics thiab cov ntawv ci kub kuj tau txais kev saib xyuas. Txoj Cai PIVOTAL los ntawm GV Dub nyob rau xyoo 18955 formalized ntau ntawm cov tawg nce qib. Gutta-percha nrhiav tau xyoo 1842, tau dhau los ua cov khoom tseem ceeb rau cov khoom siv rau hauv lub sij hawm 1847. Cov roj hmab vulcanized, siv nyob rau hauv nruab nrab {6}}}}}}}}}}} hloov los ntawm methacrylate hauv paus xyoo 1937.
Cov ntaub ntawv tshaj lij
Txij li thaum xyoo 20, cov ntaub ntawv kho hniav tau ua ntau dua, thiab muaj peev xwm ntshiab rau cov tshuaj schthesis thiab kev hloov kho lub cev tau tsim. Acrylic resin hloov vulcanized roj hmab rau cov vaj tse huv, thaum tsis muaj nqi hlau thiab stainless hlau tau siv rau cov khoom siv hluav taws xob orthodontic. CAM CAM SIM YOG KEV PAB CUAM THIAB NTAU NTXIV Cov Khoom Siv Kev Kho Mob
Sij hawm dhau los, cov ntaub ntawv xws li hlau porcelain hmoov, cov khoom noj kom zoo nkauj tau tshwm sim, txhawb nqa hniav ib leeg thiab cov choj sib txuas. Niaj hnub no, ntau qib kev txhais khoom muaj peev xwm muaj kom haum rau tus neeg mob xav tau thiab cov kev nyiam ntawm cov kws kho hniav. NtawmHonchon, peb txiav cov ntaub ntawv zirconia thiab lithium disilicate tau tas sim nyob rau hauv chaw kuaj mob thiab kev ua lag luam thoob ntiaj teb, ua kom zoo nkauj ruaj khov thiab tsim nyog.
Txawm hais tias cov ntaub ntawv kho hniav tau siv rau xyoo txhiab, kev ntawm cov ntaub ntawv kev tshawb fawb tau los ua kev qhuab qhia ywj pheej nkaus xwb hauv xyoo pua 20. Ua ntej 1900, tsuas yog ob peb yam tshwj xeeb hauv daim teb no. Niaj hnub no, cov tub txawg hauv kev sib txawv, physics, chemistry, thiab engineering yog nce tshawb fawb thiab kev kawm nyob rau hauv cov ntaub ntawv kho hniav. Ntau lub tsev kawm ntawv kho mob muaj cov tsev kawm ntawv kho mob siab heev, muab cov tswv yim thiab kws qhia ntawv cob qhia cob qhia cov kws tshaj lij kev cob qhia hauv no puas yog-loj hlob teb.
Txij li thaum tsim cov txheej txheem ua ntej rau cov hniav kev kho hniav (cov qauv kev kho kom zoo rau cov ntaub ntawv kho hniav, cov cuab yeej siv tau tsim. Qhov tshwm sim tau tsim ntawm cov ntaub ntawv ntawm cov ntaub ntawv ntawm qhov ncauj kev tshawb fawb raws li kev lees paub ntawm tus nqi kev kawm thiab keeb kwm science.Honchon, ua ib tug thawj coj hauv cov ntaub ntawv kho hniav, zoo siab ua rau cov kev lig kev cai no, muab cov kev daws teeb meem zoo uas ua tau cov kev xav tau ntawm cov kab mob thoob ntiaj teb thoob ntiaj teb.
