Kev kho hniav acrylic hniav sim-nyob rau hauv yog ib qho tseem ceeb ua ntej- theem meej nyob rau hauv tshem tawm cov hniav cuav fabrication, ua hauj lwm raws li kev soj ntsuam validation kauj ruam rau ob qho tag nrho thiab ib nrab acrylic hniav hniav. Nws suav nrog kev sim tus qauv hniav hniav- tsim los nrog lub tshav kub- kho cov hniav dawb acrylic resin puag (mimicking xim, stippling, thiab contour ntawm ntuj gingiva) thiab resin- cov hniav sib xyaw cov hniav (nrog rau tus neeg mob lub ntuj ntxoov ntxoo, cov duab, thiab {6} daim ntawv) kev ua haujlwm zoo, kev zoo nkauj, thiab kev nplij siab ntawm tus neeg mob ua ntej ua tiav qhov kev kho dua tshiab.
Tus qauv yog tsim raws li tus neeg mob lub pob zeb cam khwb cia (replicating edentulous ridges, seem abutment hniav, thiab occlusal kev sib raug zoo) thiab teem kom tsim ib tug balanced intercuspal txoj hauj lwm (ICP), kom zoo overjet / overbite, thiab harmonious lub ntsej muag profile. Thaum lub sij hawm sim- nyob rau hauv kev teem caij, cov kws kho mob ua cov kev ntsuam xyuas tag nrho: ntsuam xyuas lub rooj zaum ntawm cov hniav kom raug (ua kom tag nrho cov kev hloov mus rau lub edentulous ridge tsis rocking), occlusal stability (tshem tawm ntxov ntxov hu los yog cuam tshuam), phonetic clarity (hais lus hais lus distortionth ntawm lub hauv paus ntawm cov ntaub so ntswg mos) los ntawm cov ntaub so ntswg tsis haum. los ntawm overextended ciam teb), thiab aesthetic congruence (xyuas cov hniav ntxoov ntxoo, alignment, thiab luag kab).
Cov kev hloov kho uas tau ua nyob rau theem no suav nrog kev hloov kho cov hniav txhawm rau kho qhov sib nrug los yog angulation, trimming overextended acrylic puag ciam teb, sib tsoo cov hniav cusps kom ua kom zoo occlusion, txo cov ntsiab lus siab ntawm lub hauv paus cov ntaub so ntswg -fab qhov chaw, thiab kho lub hauv paus contour kom haum. Cov theem no yog qhov hloov tsis tau vim nws daws qhov tsis zoo ntawm kev ua haujlwm thiab kev zoo nkauj thaum ntxov, txo qhov xav tau tom qab- kev hloov kho thiab ua kom cov hniav zoo nkauj muab cov kev ua tau zoo masticatory, ntev - lub sij hawm kev nplij siab, thiab cov neeg mob siab. Kev hla lossis maj nrawm ntawm kev sim- tuaj yeem ua rau muaj mob - cov hniav cuav, kev cuam tshuam tsis zoo, thiab txo kev kho mob kom zoo.
