Kws Kho Hniav-qib daj resin feem ntau yog hais txog lub teeb-kho cov khoom sib xyaw uas tsim los rau kev kho hniav. Cov ntaub ntawv no tau ua tib zoo ntxoov ntxoo kom phim lub ntuj daj tones ntawm tib neeg dentin lossis cov hniav tom qab. Qee zaum, hloov kho iav ionomer cements nrog daj tinting kuj tseem siv, tshwj xeeb tshaj yog rau cov menyuam yaus lossis cov ntawv siv hauv paus.
Core Composition of Light-Cured Composite Resin
1. Resin Matrix (Organic Phase)
Feem ntau suav rau 20-40% los ntawm qhov hnyav.
Feem ntau monomers muaj xws li:
Bis{0}}GMA (bisphenol A diglycidyl methacrylate)
UDMA (urethane dimethacrylate)
Feem ntau sib xyaw kom pom kev zoo viscosity, lub zog, thiab yoog raws
Lub network polymer no muab cov qauv pob txha caj qaum tom qab kho thiab pab txhawb rau adhesion thiab toughness.
2. Inorganic Fillers
Feem ntau 60-80% los ntawm qhov hnyav.
Cov khoom tseem ceeb:
Siab -purity spherical silica (silicon dioxide)
Radiopaque barium los yog strontium iav hais
Qhov ntau thiab tsawg yog tswj tau (feem ntau 0.01-10 μm, suav nrog nano thiab micro loj) kom sib npaug txhua yam muaj zog, polishability, hnav tsis kam, thiab X-ray visibility.
3. Cov khoom siv ntxiv
Photoinitiators (feem ntau yog camphorquinone) qhib los ntawm kev kho hniav teeb hauv 400–500 nm xiav- teeb ntau
Co-initiators / accelerators (amines)
Inhibitors los xyuas kom meej lub sij hawm ua hauj lwm txaus thiab tiv thaiv ntxov ntxov polymerization thaum lub sij hawm cia
Kev kho feem ntau tshwm sim hauv 10-60 vib nas this nyob ntawm txheej tuab thiab lub teeb siv.
4. Kev kho mob-Grade Colorants
Cov xim daj yog ua tiav nrog biocompatible, kho mob -qib xim xws li hlau oxide daj lossis lwm yam xim tsis muaj organic / organic pom zoo. Cov no yuav tsum ua tau raws li qhov ncauj biocompatibility nruj thiab cov qauv kev nyab xeeb. Kev lag luam - qib dyes yeej tsis siv.
Hloov Kho Ionomer Cement (Lwm txoj kev xaiv daj)
Qee cov ntaub ntawv kho mob daj yog ua raws li kev hloov kho iav ionomer tshuab:
Polyacrylic acid matrix + fluoro-aluminosilicate iav hmoov
Zinc polycarboxylate Cheebtsam nyob rau hauv tej formulations
Ntxiv kev kho mob - qib daj xim xim
Cov ntaub ntawv no tso tawm cov tshuaj fluoride thiab feem ntau nyiam rau kev kho hniav thawj zaug lossis ua cov ntaub ntawv hauv qab / liner. Lawv lub zog txhua yam feem ntau qis dua li ntawm hybrid lossis nanofilled composite resins.
Kev siv tshuaj kho mob ib yam ntawm daj-Shade Resins
Rov qab kho dua: Daj tones zoo dua cov xim ntuj ntawm molars thiab premolars nyob rau hauv occlusal load. High-cov khoom siv sib xyaw ua ke muab qhov tsim nyog compressive zog thiab hnav tsis kam.
Txheej anterior restorations: Dentin lossis lub cev ntxoov ntxoo daj / daj-xim av tau muab tso rau hauv cov txheej txheem los thaiv cov keeb kwm yav dhau los thiab tsim qhov tob tob ua ntej enamel- cov txheej txheej ntxoov ntxoo ntxiv.
Pediatric kho hniav: Fluoride- tso cov iav daj ionomers lossis cov khoom sib xyaw feem ntau xaiv rau cov hniav vim lawv cov kab mob -cov txiaj ntsig tiv thaiv thiab siv tau yooj yim.
Cov ntsiab lus tseem ceeb rau cov kws kho mob thiab cov neeg mob
Kev vam meej nyob ntawm kev sib cais kom raug, cov txheej txheem nplaum nplaum, qhov kev tso kawm ntxiv, kev kho lub teeb kom txaus, thiab ua tiav. Kev xaiv ntxoov ntxoo yuav tsum xav txog tus neeg mob lub hnub nyoog, qhov chaw ntawm cov hniav, thiab cov hniav nyob ib puag ncig. Nco ntsoov xyuas kom meej tias cov khoom siv kho mob tsim nyog - cov ntaub ntawv pov thawj rau kev siv intraoral.
Txawm hais tias cov khoom sib xyaw ncaj qha (xws li ua tib zoo sib xyaw xim daj) tseem yog lub hauv paus ntawm kev saib xyuas kev kho hniav, cov kev ua haujlwm digital tau nce ntxiv rau hauv kev kho kom rov zoo. Qhov tseeb intraoral scanning, CAD tsim, thiab 3D luam ntawv ntawm kev kho dua tshiab, qauv, thiab cov lus qhia txhim kho qhov tseeb thiab kev ua haujlwm nrog rau cov khoom siv ib txwm muaj.
Aident3D tshwj xeeb hauv kev daws teeb meem kev kho hniav digital ua tiav - hmoov- cov tshuab kuaj kab mob hauv lub cev tsis pub dawb, lub tshuab kuaj kab mob hauv lub cev, qhib- tshuab 3D tshuab luam ntawv, thiab siab -kev ua haujlwm kho hniav - tsim los txhawb cov chaw kho mob niaj hnub thiab chaw kuaj mob.
Tshawb nrhiav yuav ua li cas cov cuab yeej digital tuaj yeem txhim kho koj cov txiaj ntsig kho dua tshiab
