Occlusion - tiv tauj thaum kaw cov hniav. Orthodontist daws cov teeb meem zoo li no. Orthodontics ntawm mesial occlusion suav nrog txhua ntu ntawm qhov tshwm sim no - los ntawm etiology mus rau kev kho mob thiab kev tiv thaiv.
Overbite yog ib qho txawv txav uas kab ntawm cov hniav ntawm lub mandible overlaps cov hniav ntawm kab sab sauv thaum lub puab tsaig kaw. Ces ib tug yam ntxwv kauj ruam yog tsim. Pathology pom nyob rau hauv 11.8% ntawm cov neeg mob. Nws yog suav hais tias yog ib tug complex dentoalveolar curvature. Qhov opposite ntawm nws yog qhov distal tom, qhov twg txhua yam yog raws nraim opposite.
cov ntaub ntawv dav dav
Mesial occlusion tseem tuaj yeem ua ke nrog lwm cov malocclusions - ntsug thiab transversal (hla), nrog rau kev hloov ntawm tus neeg cov hniav, nrog rau qhov qhib tom. Hauv kev kho hniav, mesial occlusion yog hu ua "progenia", "anterial occlusion", qis prognatia. Feem ntau, nws hloov tawm mus rau underdeveloped lub puab tsaig sab sauv los yog ib yam nkaustsim hauv qab.
Lo lus "mesial occlusion" tau qhia rau hauv orthodontics hauv xyoo 1926 los ntawm Lischer. Thiab rov qab rau xyoo 1899, E. Engle tau tsim ib qho kev faib tawm ntawm cov kab mob dentoalveolar, qhov uas nws tau suav tias yog progeny rau hauv chav kawm III anomalies, uas txhais tau hais tias qhov chaw ntawm thawj zom cov hniav (molars) nyob rau hauv pem hauv ntej ntawm lub sab sauv sawv daws yuav thaum kaw.
Tau ntau pua xyoo, cov neeg uas muaj teeb meem zoo li lub puab tsaig qis qis tau raug cais raws li lub siab tsis muaj zog, tab sis ntawm lawv yog tus cwj pwm zoo - Emperor Charles V thiab tus kws sau ntawv zoo Richard Wagner. Cov duab ntawm mesial occlusion yuav nthuav tawm hauv qab no.
Cas of anomaly
Mesial occlusion yog polyetiological - nws tuaj yeem tshwm sim los ntawm cov kab mob caj ces, congenital thiab kis tau. Cov noob caj noob ces nyob ntawm 20-40% ntawm tag nrho cov mob thiab muaj feem xyuam nrog cov yam ntxwv ntawm cov pob txha ntawm lub ntsej muag ntawm pob txha taub hau uas tau dhau los ntawm ntau tiam neeg.
Thaum lub sij hawm cev xeeb tub, cov kab mob ntawm tus poj niam cev xeeb tub, traumas thiab pathologies ntawm kev yug me nyuam, lub puab tsaig hypoplasia, thiab lwm yam ua rau kev ua txhaum cai. Cov provocative yam yuav ua rau cov hniav ntawm lub puab tsaig qis tshaj, adentia ntawm txawv. degrees nyob rau hauv lub puab tsaig sab sauv (tsis muaj cov hniav), microdentia ntawm cov hniav sab sauv, shortening ntawm frenulum ntawm tus nplaig los yog nws loj loj.
Ua rau mesial occlusion ntawm cov hniav tuaj yeem yog:
- me nyuam yaus rickets;
- khoom noj khoom haus;
- kev ua txhaum txoj haujlwm ntawm tus menyuam hauv npau suav (tso lub taub hau rau hauv siab);
- txhawb lub puab tsaig thaum zaum;
- osteomyelitis ntawm lub puab tsaig sab sauv;
- kab mob ENT (tshuaj tonsillitis, deviated nasalpartitions);
- pib hloov cov mis nyuj cov hniav ntawm lub puab tsaig sab sauv;
- hnav tsis sib xws ntawm cov menyuam yaus cov hniav (canines);
- ncua kev loj hlob ntawm cov hniav mus tas li.
Yog tias cov kua mis tsis tau hnav dhau sijhawm, qhov no tseem yuav ua rau qhov txuas ntxiv ntawm lub mandibular ntawm pob txha taub hau mus rau pem hauv ntej. Nyob rau hauv txoj hauj lwm no, nws nyob ruaj khov. Cov cwj pwm tsis zoo xws li nqus tus ntiv tes, tus nplaig, daim di ncauj, thiab lub txiv mis tas li hauv lub qhov ncauj muaj qhov cuam tshuam tsis zoo rau cov tsos mob ntawm tus menyuam.
Kev faib tawm
Muaj 3 daim ntawv ntawm mesial occlusion. Lawv yuav tau tham hauv qab no. Yog li, kev faib tawm ntawm pathology:
- Qhov tseeb mesial occlusion, los yog qhib, yog ib hom kab mob pathology thiab tshwm sim hauv cov neeg sawv cev ntawm tib lub genus, dhau los ua lawv cov cim. Qhov tsis raug tom raug kuaj pom twb nyob rau thawj xyoo ntawm lub neej. Lub provoking noob tshwm sim nyob rau hauv cov xeeb ntxwv nyob rau hauv 30% ntawm cov neeg mob. Feem ntau tus mob khaub thuas ntawm tus poj niam cev xeeb tub hauv thawj peb lub hlis twg los ua ib lub sijhawm pab.
- Tsis tseeb, lossis kaw cov neeg laus - qhov ua rau muaj qhov tshwm sim ntev ntawm lub puab tsaig qis hauv lub xeev siab heev rau ntau yam laj thawj: qhov mob ntawm nasopharynx, thaum ua pa tawm los ntawm lub qhov ncauj. Lub frenulum luv luv ntawm tus nplaig (tsis txiav) kuj tuaj yeem ua rau. Qhov anomaly yuav pom thaum cov hniav raug kaw. Kev kuaj mob tuaj yeem ua tau tom qab 12 xyoos. Visually, tej zaum nws yuav tsis pom.
- Cov ntaub ntawv sib xyaw ntawm mesial occlusion - kev sib xyaw ntawm 2 qhov kev xaiv dhau los. Daim foos no yog qhov kuaj pom thiab kho tau phem tshaj plaws.
Sub raumalocclusion nyob rau hauv lub dav hlau sagittal thiab lub kaum sab xis ntawm lub puab tsaig sab hauv kev faib tawm ntawm mesial occlusion, muaj 3 degrees ntawm pathology raws li lub kaum sab xis:
- First degree - sagittal qhov sib txawv ntawm lub puab tsaig ntawm lub puab tsaig los ntawm 3 hli, tab sis tsis ntau tshaj 5 hli, mandibular lub kaum sab xis mus txog 131 °.
- Second degree - sagittal fissure txog 10 hli, lub kaum sab xis ntawm lub mandibular mus txog 133 °.
- Thib peb - sagittal fissure ntau dua 10 hli - 11-18 hli, lub kaum sab xis ntawm lub mandibular mus txog 145 °.
Dab tsi yog qhov sagittal fissure? Qhov no yog qhov kev ncua deb ntawm cov hniav pem hauv ntej ntawm lub puab tsaig sab sauv mus rau pem hauv ntej cov hniav ntawm lub puab tsaig sab. Los ntawm txoj kev, nrog ib tug sagittal fissure ntawm ntau tshaj 10 hli, ib tug tub hluas tej zaum yuav raug xam tias yog conditionally haum thaum sau rau hauv cov tub rog. Qhov systematization no tau tsim rov qab rau xyoo 1898 thiab muaj qhov tsis zoo.
Engl coj mus rau hauv tus account ntawm no qhov kev hloov ntawm cov hniav tsuas yog nyob rau hauv lub sagittal kev taw qhia, tab sis qhov kev khiav hauj lwm xyaum tshwm sim nyob rau hauv peb kev sib nrig sib perpendicular cov lus qhia. Yog li ntawd, niaj hnub no xws li kev faib tawm tsuas muaj keeb kwm nam, txawm hais tias nyob rau qee qhov chaw nws tau siv txawv teb chaws.
Muaj 3 hom kev qis qis: qhib, tob thiab hla.
Shapes
Muaj 3 hom mesial tom:
- Thawj daim ntawv - tsis muaj qhov sib txawv ntawm lub puab tsaig, mandible central incisors sib tshooj ntawm cov hniav.
- Daim ntawv thib ob - cov hniav hauv qab twb ncav cuag cov mucous ntawm daim di ncauj. Lub puab tsaig hauv qab yog tsim thiab loj dua lub sab sauv, tab sis tsis ntau.
- Daim ntawv thib peb - hauv qhov version no, lub puab tsaig sab sauv me duaqis. Cov hniav pem hauv ntej tsis kov. Tus nplaig nias rau ntawm cov hniav sab sauv.
Tseem muaj cov ntaub ntawv kho mob dentoalveolar thiab gnathic ntawm mesial occlusion. Hauv thawj kis, lub puab tsaig qis tuaj yeem txav mus rau qhov raug tom ntawm cov hniav zom. Daim ntawv gnathic tsis tso cai hloov chaw.
Symptomatic manifestations
Mesial occlusion sib raug rau qhov kaw ntawm cov molars raws li 3rd Angle chav kawm - qhov no yog sagittal malocclusion. Nyob rau tib lub sijhawm, qhov kev hloov pauv mesial ntawm cov yas ntawm thawj cov hniav zom los ntawm 0.5 ntawm qhov dav ntawm tubercle lossis ntau dua yog qhov kev kuaj mob tseem ceeb.
Mesial occlusion tsev kho mob nyob rau hauv sab nraud tshwm sim yog qhia nyob rau hauv ib tug loj protruding puab tsaig (masculine), qhov profile ntawm nruab nrab ntawm lub ntsej muag yuav concave rau txawv degrees, lub sab sauv dab dej, thiab daim di ncauj qis protrudes.
Fim npau taws. Lub ntsej muag zoo li no hauv cov txiv neej feem ntau suav hais tias txawm tias ntxim nyiam thiab yog txiv neej, tab sis rau tus poj niam tus cwj pwm no yog qhov txawv ntawm lub ntsiab lus.
Daim di ncauj sab sauv me me thiab luv dua li ntawm daim di ncauj qis, thiab ib feem ntawm lub ntsej muag hauv qab lub qhov ntswg kuj zoo nkaus li luv luv.
Mesial occlusion kuj yog qhov muaj txiaj ntsig ntawm kev hloov pauv - hais lus thiab zom tau cuam tshuam.
Speech ua lispy lossis burr, diction yog slurred. Tom thiab zom zaub mov ua teeb meem. Cov nasolabial folds ua kom meej meej, tob, qhov ntswg yog elongated, qhov loj ntawm tus nplaig yog nce. Thaum zom, tej zaum yuav muaj crunch, lateral txav ntawm lub puab tsaig hauvcov neeg mob nyuaj.
Kev kuaj mob ntawm tus menyuam
Rau qhov kev kuaj mob ntawm mesial occlusion, nws yog ib qho tsim nyog los sab laj tus kws kho hniav - tus kws kho mob tshwj xeeb hauv kev kho lub puab tsaig pathologies. Nws yuav tsis tsuas yog ua ib qho kev ntsuam xyuas pom thiab siv anthropometry los ntsuas cov kab mob pathology, tab sis kuj ua cov kev ntsuam xyuas ua haujlwm kom cais cov ntawv tseeb thiab tsis tseeb. Rau lub hom phiaj no, tomography wax rollers, tomography, radiography, orthopantomography yog siv. Raws li kev kuaj mob ntxiv, myography ntawm masticatory thiab lub cev nqaij daim tawv yuav ua tau.
