Hauv kev kho hniav, muaj ob peb hom kev tsis haum ntawm lub puab tsaig sab nraud thiab sab nraud. Ib qho ntawm cov pathologies uas feem ntau yog qhov prognathic lossis distal occlusion, raws li kev txheeb cais, nws tshwm sim nyob rau hauv yuav luag ib nrab ntawm cov neeg mob uas tau tig mus rau lub orthodontist.
Ntxiv rau qhov tsis pom zoo, nrog rau qhov teeb meem no, muaj ntau cov teeb meem raug sau tseg - kev ua txhaum ntawm lub luag haujlwm ntawm nqos thiab zom khoom, kev cuam tshuam ntawm kev sib koom ntawm lub cev. Txoj kev pheej hmoo ntawm kev sib tw thiab kev txhim kho cov kabmob kuj nce siab.
Dab tsi yog qhov sib sib zog nqus distal?
Qhov piav qhia ntxeev yog pom los ntawm cov protrusion ntev ntawm lub puab tsaig sab nraud, thaum nws overlaps lub puab tsaig sab nraud loj heev. Tsis tas li, tag nrho cov hniav thiab qis qis txav ib leeg rau ib leeg - lawv raug kaw tsis tau.
Kev coj noj coj ua yog feem ntau yog nrog cov phiaj xwm sab nraud:
- convex ntsej muag;
- luv luv thiab protruding sab saum toj;
- rov qab chin;
- lub puab tsaig sab nraud dhau deb tshaj rau hauv qis;
- tsis tiav kaw daim di ncauj;
- qee zaum cov di ncauj sab qab nyob rau hauv qab lub incisors ntawm lub sab nrauv.
Puas yog ua tau los kho qhov distal occlusion tsis muaj kev phais?
Contrary rau kev ntshai ntawm feem ntau cov neeg mob, tus nyeem mas yog tsis tshua muaj neeg tsis tshua muaj kev phais kho. Txoj kev kho mob ntawm kev kho mob ntawm qhov distal occlusion nrog kev pab ntawm osteotomy tsuas yog ua rau cov neeg tsis saib xyuas thiab mob hnyav nyob rau hauv qhov muaj qhov qhia tau tias:
- asymmetry ntawm lub ntsej muag;
- qhib frontal occlusion;
- chin dysplasia;
- degenerative hloov ntawm cov temporomandibular sib koom tes.
Tsis tas li ntawd tsawg incasive techniques yog siv rau kev kho ntawm occlusion - kho vajtse-phais thiab prosthetic technologies, lawv ua ke.
Raws li txoj cai, qhov teeb meem yuav tshem tawm los ntawm kev siv bracket systems. Lawv zoo txawm tias hauv neeg laus.
Kho ntawm distal tom los ntawm kev zawm hniav
Yuav kom tau qhov kev xav tau zoo, koj yuav tau ua siab ntev thiab mob siab, vim kev kho mob ntawm cov laus yuav siv sijhawm ntev li 3-4 xyoo.
Lub sijhawm no, nws yog ib qho tseem ceeb kom tas li thiab hloov lub moos kom hnav txoj hlua , kev kho ntawm qhov kev txiav txim siab yuav los ntawm tus kws kho mob raws li txoj kev npaj kho kho. Qee qhov xwm txheej, txoj kev kho mob no yog kev sib txuas los ntawm kev siv cov cuab yeej kho tshuab:
- lub ntsej muag arc;
- lub Sabbah lub caij nplooj ntoos hlav;
- cov cuab yeej ntawm Gerbst;
- intermaxillary thiab swb traction thiab lwm tus.
Nws yog tsim nyog sau cia tias txawm tias tom qab qhov kev tshem tawm ntawm lub bracket system, mus ntev lub sij hawm kho thiab fixation ntawm cov nyhuv yog yuav tsum tau. Rau lub hom phiaj no, kev siv cov khoom tshem tawm lossis ruaj ntseg retention devices, cov kws qhia (tuav) rau xyoo tom ntej 4,5-8. Qee lub sij hawm nws yog ib qho tsim nyog los kho qhov kev kho mob nrog txoj kev phais mob - compactotestomy, tshem tawm ntawm qee cov hniav.
Myogymnia nrog kev tsis sib haum xeeb
Vim tias muaj kev txaus ntshai ntawm kev mob thiab kev hloov ntawm cov teebmeem hauv lub cev, nws yog ib qho tseem ceeb uas yuav tsum tau saib xyuas kom muaj zog rau cov leeg nyob ib puag ncig. Orthodontists pom zoo rau lawv txoj kev kawm kom xwm yeem ua ob peb qhov kev ua tau yooj yim los ntawm qhov kev xeem ntawm myogym:
- Inflate thiab deflate lub puab tsaig.
- Rub lub duav rau hauv lub raj.
- Ncab koj lub qhov ncauj ua luag nyav.
- Tshem tawm sab puab lub puab tsaig sab nraud ntawm lub puab tsaig sab nraud.
- Qhib koj lub qhov ncauj dav.
Nws yog ib qho tseem ceeb pab nplawm balloons, tso tawm cov tswm ciab nrog koj ua pa, feem ntau luag nyav.
Nws yog ntshaw tias lub ce yog nqa tawm thaum sawv ntxov thiab maj mam. Rau lawv cov kev coj ua yuav tsum muab faib tsawg kawg 10-15 feeb, maj mam ua.
