Malocclusion ntawm Cov Hniav hauv Cov dev

Nquag, tus menyuam dev yuav muaj 28 tus hniav thaum nws muaj rau lub hlis. Txog thaum nws ncav cuag kev laus, feem ntau cov dev yuav muaj 42 hniav. Qhov tsis zoo ntawm cov dev cov hniav, lossis malocclusion, tshwm sim thaum lawv tom tsis haum raws li. Qhov no yuav pib thaum tus menyuam cov menyuam menyuam cov hniav nkag los thiab feem ntau yuav ua rau mob hnyav thaum lawv cov hniav laus.

Lub ntsej muag me me ua ntej ntawm cov kis tau ntawm lub puab sab sauv thiab sab hauv qab yog hu ua incisors. Cov no yog siv los txhawm rau khaws cov zaub mov thiab ua kom tus nplaig nyob hauv qhov ncauj. Canines (tseem hu ua cuspids lossis fangs) pom nyob tom qab cov hniav pem hauv ntej, uas tseem tau siv los tuav. Qab tus canines yog cov premolars (lossis bicuspids) thiab lawv txoj haujlwm yog ua haujlwm txiab lossis txiav cov zaub mov. Molars yog cov hniav kawg ntawm qhov ncauj pom thiab lawv siv los zom.

Cov tsos mob thiab Hom

Cov teeb meem tshwm sim uas tuaj yeem tshwm sim los ntawm malocclusion:

• Qhov ncauj kev raug mob
• Tus kab mob pheej ncig
• Cov leeg mos mos tsis xws luag tawm ntawm hniav mus rau hauv pem teb ntawm lub qhov ncauj thiab lub ru tsev ntawm lub qhov ncauj (lub qhov ncauj)
• Hnav ntawm cov hniav
• Puas taus

Yog tias muaj teeb meem ntawm lub palate pheej mob, lub fistula tuaj yeem ua thiab kis tus kabmob. Thaum muaj misaligned (los yog malocclusion), tus dev yuav muaj teeb meem zom, tuaj tos zaub mov noj, thiab tej zaum yuav xav noj tsuas yog qhov loj dua. Lawv yog cov nquag muaj tartar thiab quav hniav ua-ua.

Muaj ntau ntau hom kev kuaj mob malocclusion:

• Overbite (qee zaum hu ua overshot, Chav 2, overjet, lossis mandibular brachygnathism)
• Underbite (tseem hu ua undershot, thim rov tom qab scissor tom ntej, kev kwv yees, thiab Chav Kawm 3)
• Qib tom (qee zaum hu ua txawm tias tom)
• Qhib kev tom (cov hniav pem hauv ntej tsis tau sib ntsib thaum kaw lub qhov ncauj)
• Anterior crossbite (canine thiab premolars occlude feem ntau tab sis ib lossis ntau dua incisors nyob rau hauv pem hauv ntej ntawm lub sab sauv)
• Cov txha caj qaum (ib lossis ntau dua cov hniav premolar sib tshooj rau cov hniav sab saud)
• Wry qhov ncauj los yog tom (ib sab ntawm lub puab tsaig hlob dua li lwm qhov)
• Lub hauv paus nqaim nqaim (cov hniav sab hauv tuaj sab hauv thiab tuaj yeem ua rau sab qaum)

Cov lus qhia ntawm cov premolars (cov hniav tom qab tus canines) yuav tsum kov qhov chaw nruab nrab ntawm cov tsev kho mob sab saud, uas hu ua scissor tom. Txawm li cas los xij, nws yog qhov ib txwm muaj rau cov tiaj-ntsej muag hom (brachycephalic) xws li Boxers, Shih Tzus, thiab Lhasa Apsos kom tsis txhob muaj cov scissor tom.

Nrog rau kev tawm tsam, lub puab tsaig sab sau ntev dua qhov qis dua. Thaum lub qhov ncauj raug kaw, muaj qhov sib txawv nruab nrab ntawm qhov siab thiab qis dua tshwm sim. Cov menyuam dev yug nrog ib tug overbite yuav qee zaum muaj qhov teeb meem kho nws tus kheej yog tias qhov tsis sib txawv tsis loj heev. Txawm li cas los xij, txoj cai dev yuav raug teeb tsa thaum muaj kaum hli. Lub sijhawm no txhim kho yuav tsis tshwm sim ntawm nws tus kheej. Koj tus tsiaj lub ntsej muag yuav muaj ntau zuj zus vim tias cov hniav tas mus li vim tias lawv loj dua thiab tuaj yeem ua rau puas qhov chaw mos ntawm lub qhov ncauj. Qee zaum yuav tau rho hniav mus ntxiv.

Ua rau

Txoj kev ntawm cov hniav sab saud nrog cov hniav hauv qab yog hu ua occlusion. Nws yog qhov ib txwm muaj rau feem ntau ntawm cov tsiaj muaj me ntsis sib tshooj ntawm lub hauv ntej cov hniav. Thaum lub puab tsaig raug kaw, qhov qis dua canine (fang) yuav tsum haum rau pem hauv ntej ntawm lub canine sab saud. Feem ntau ntawm malocclusion muaj qhov sib txuas keeb.

Kev Kho Mob

Feem ntau tom malocclusions tsis tas yuav tsum tau kho. Qee qhov xwm txheej, kev so mus ntxiv yuav tsim nyog. Nws yog ib lub tswv yim zoo los txhuam hniav tas li kom tiv thaiv qhov txawv txav ntawm tartar thiab cov quav hniav. Tus kws kho tsiaj yuav qee thaum hais qhia kws kho hniav yog tias koj xav kho tus hniav tsis raug. Xyoo tsis ntev los no, "kev zawm hniav" tau ua rau cov menyuam dev ua kom pom cov hniav.
