1. Composite resin
Raws li acrylic resins, qhov sib ntxiv ntawm iav, quartz, thiab lwm yam khoom los txhim kho kev ua tau zoo yog cov khoom siv feem ntau siv rau cov khoom ntim. Cov khoom sib xyaw muaj cov xim tiag tiag thiab zoo nkauj zoo li cov hniav, nws yog cov nplaum rau cov qauv ntawm cov hniav thiab cov molars kuj me me, thiab muaj cov resin tsim los sau cov hniav tom qab, uas yog qhov zoo nkauj thiab muaj zog. , thiab tuaj yeem hloov cov khoom siv amalgam tag nrho. Qhov tsis zoo yog tias ob peb tus neeg tsis haum rau cov ntaub ntawv resin thiab yuav tsum siv lwm cov ntaub ntawv. Tsis tas li ntawd, filling composite resins yuav tsum muaj kev txawj ntse dua ntawm cov kws kho mob.
2. Amalgam
Amalgam yog cov khoom siv kho hniav classic. Nws tau siv ntau pua xyoo thiab hnyav heev. Nws kuj yog ib qho kev txhim khu kev kho hniav zoo heev rau cov hniav tom qab. Txawm li cas los xij, qhov tsis zoo yog cov xim tsis zoo nkauj, tsis ua rau cov hniav hauv pem hauv ntej, nws tsis nplaum, nws yog qhov sib tsoo ntau, cov hlau ua kom sov, nws yooj yim rau khaus cov tawv nqaij, thiab kev txhawj xeeb txog mercury thiab mercury nyob rau hauv tib neeg lub cev thiab ib puag ncig thaum lub sij hawm ua hauj lwm tej zaum yuav muaj kuab paug Yog, kev siv tam sim no poob siab.
3. iav ionic cement
Iav ionomer binders yog tsim los ntawm reacting iav hmoov nrog polyacrylic acid los tsim cov polymers uas muaj ionic bonds. Vim tias qhov tso tawm ntawm cov tshuaj fluoride ions, caries tuaj yeem tiv thaiv tau qee qhov, muaj qee yam tshuaj adhesion rau amalgam, thiab nws tsis yog khaus heev rau cov tawv nqaij. Txawm li cas los xij, nws tsis zoo thiab nyuaj nrog rau cov khoom sib xyaw. Yog li ntawd, tam sim no nws yog siv los kho cov kab mob caries thiab cov yas ntim tom qab txhaws, tsis tau txhais hais tias koj tuaj yeem hloov cov hniav qub thiab noj zaub mov txias.
4. Nano cob
Lub granularity ntawm nws cov muab tub lim mus txog rau theem nanometer, nws yog translucent, thiab muaj ib tug milky xim, uas muaj zoo fidelity, ntau hnav-resistant, thiab tsis yooj yim rau poob tawm tshaj li composite resins, tab sis nws kuj yog kim kim. Tam sim no, qhov nrov tshaj plaws ntawm kev ua lag luam yog 3M nano resin.
5. Ib qho inlay
Hais lus nruj me ntsis, qhov no yog ib txoj kev kho hniav kho hniav. Tsis zoo li cov tsoos sau, inlays yog tsim los ntawm ib tus kws kho hniav tshwj xeeb ntawm ib qho plaster cam khwb cia, uas tom qab ntawd hnav rau hauv tus neeg mob lub qhov ncauj los ntawm tus kws kho mob thiab thaum kawg cemented.
