Ib qho tag nrho -arch workflow qhia PMMA tus nqi kom meej. Ua ntej milling tus choj zirconia kawg, lub chaw kuaj mob tuaj yeem tsim PMMA qauv. Tus kws kho hniav tuaj yeem tshawb xyuas daim di ncauj, midline, incisal edge position, phonetics, tom, thiab tus neeg mob kev nplij siab.

Cov kauj ruam ntawd tuaj yeem tiv thaiv cov khoom kim heev.

Rau kev cog qoob loo, PMMA tseem tuaj yeem pab tsim cov ntaub so ntswg thiab kuaj qhov tshwm sim ua ntej qhov kawg rov kho dua. Hauv cov xwm txheej no, PMMA tsis yog cov khoom siv ib ntus xwb. Nws yog cov cuab yeej kuaj mob.

Vim li cas PMMA yuav tsum tsis txhob siv zoo li zaum kawg Ceramic

PMMA muaj kev txwv.

Nws yog feem ntau hnav, staining, plaque tsub zuj zuj, thiab tawg dua li cov ntaub ntawv ceramic. Nws yooj yim dua los kho, tab sis tib lub cuab yeej txhais tau tias nws tsis tuaj yeem muab tib lub sijhawm ntev - kev ua tau zoo li zirconia lossis lithium disilicate hauv kev kho zaum kawg.

Cov kev xaiv PMMA tuaj yeem txhim kho qee yam khoom, tab sis nyob rau hauv kev txhim kho kev ua haujlwm ruaj khov, PMMA tseem yog cov khoom siv kho mob lossis tshuaj ntsuam xyuas.

Yog hais tias ib rooj plaub xav tau ntev -lub sij hawm thauj khoom- bearing zog, PMMA tsis yog cov lus teb kawg. Yog hais tias cov ntaub ntawv xav tau ib lub sij hawm ntsuam xyuas kev nyab xeeb ua ntej qhov kawg lawm, PMMA yuav pab tau heev.

Xaiv cov khoom tsim nyog los ntawm kev soj ntsuam xyuas

Feem ntau cov kws kho hniav thiab cov chaw kuaj mob tsis xav tau cov lus qhuab qhia ntev. Lawv yuav tsum paub seb yuav xaiv dab tsi rau rooj plaub nyob rau hauv pem hauv ntej ntawm lawv.

Cov lus hauv qab no muab cov lus qhia siv tau-raws li phau ntawv qhia.

Cov yas tom qab ntawm qhov qis - pheej hmoo premolar thiab lub puab tsaig thib ob ntawm lub bruxer tsis zoo ib yam. Ib qho anterior crown nrog cov stump tsaus tsis zoo ib yam li plaub veneers ntawm kev npaj zoo tagnrho. Kev cog qoob loo hauv thaj chaw zoo nkauj tsis zoo ib yam li cov ntsia hlau- khaws cia tom qab cog ntoo.

Cov kev sib txawv no yuav tsum coj cov kev xaiv khoom ua ntej pib tsim khoom.

Common Material Selection yuam kev kom zam

Kev xaiv cov khoom yuam kev yog ib txoj hauv kev yooj yim tshaj plaws los tsim remakes. Qhov yuam kev yuav tsis tshwm sim thaum tsim. Nws tuaj yeem tshwm sim tom qab zaum, thaum lub sijhawm ua haujlwm, lossis tom qab tus neeg mob pib siv kev kho dua tshiab.

Xaiv Tsuas yog raws li lub zog

Zirconia muaj zog, tab sis lub zog ib leeg tsis lav qhov txiaj ntsig zoo tshaj plaws.

Rau cov teeb meem anterior esthetic, tus kws kho hniav thiab chaw kuaj mob tseem yuav tsum tau txiav txim siab translucency, ntxoov ntxoo qhov tob, stump xim, incisal characterization, thiab cov hniav nyob ib puag ncig. Kev kho kom zoo dua qub uas zoo li tiaj tus lossis opaque tseem yog qhov tshwm sim tsis zoo hauv thaj chaw esthetic.

Xaiv Tsuas Raws Li Esthetics

Lithium disilicate muaj kev zoo nkauj zoo nkauj, tab sis nws yuav tsum tsis txhob raug yuam mus rau hauv siab - cov neeg kho tshuab muaj kev pheej hmoo.

Ib qhov ntev - ncua tom qab choj los yog rooj plaub bruxism xav tau ntau tshaj qhov translucency. Yog tias kev kho dua tshiab yuav ntsib qhov hnyav hnyav, cov khoom siv zog thiab qhov chaw tsim khoom yuav tsum tuaj ua ntej.

Kho PMMA raws li kev daws teeb meem tas mus li

PMMA ua haujlwm zoo raws li cov khoom siv ib ntus lossis qauv qauv. Nws yuav tsum tsis txhob muag los yog npaj raws li niaj hnub ua ntev - lub sij hawm hloov ceramic.

Thaum PMMA siv dhau nws lub hom phiaj, qhov kev pheej hmoo tuaj yeem kwv yees tau: hnav, hloov pauv, tawg, khaws cov quav hniav, thiab cov neeg mob tsis txaus siab.

Xa cov ntaub ntawv tsis tiav rau hauv chav kuaj

Qee zaum qhov kev txiav txim siab ntawm cov khoom ua tsis tiav vim lub chaw kuaj tsis tau txais cov ntaub ntawv txaus.
