Qhov Tseem Ceeb Qhov txawv - Maxillary Central vs Lateral Incisor
Kev kho hniav lub cev thiab lub cev nqaij daim tawv tau kawm ntau xyoo los qhia cov qauv thiab kev ua haujlwm ntawm ntau hom hniav, tshwj xeeb tshaj yog nyob rau hauv tib neeg. Cov hniav maxillary yog cov hniav uas muaj nyob rau hauv lub puab tsaig sab sauv uas muaj plaub hom: Incisors, Canines, Premolars, thiab Molars. Incisors tau muab faib ntxiv rau hauv maxillary central incisors thiab maxillary lateral incisors nyob ntawm lawv cov duab thiab cov qauv. Lawv yog cov yam ntxwv raws li ob peb yam: labial nam, mesial nam, distal nam thiab incisal nam. Maxillary central incisors yog lub hauv paus incisors uas tshwm sim thaum muaj hnub nyoog xya mus rau yim xyoo. Maxillary lateral incisors nyob tom qab ntawm lub puab tsaig sab sauv thiab lawv tshwm sim thaum muaj hnub nyoog yim rau cuaj. Qhov sib txawv tseem ceeb sib nrug los ntawm ntau qhov sib txawv ntawm cov qauv qhia los ntawm maxillary central thiab lateral incisors yog lawv lub sijhawm tawg. Maxillary central incisors tawg ua ntej thaum maxillary lateral incisors tawg tom qab.
Maxillary Central yog dab tsi?
Maxillary central incisors nyob hauv nruab nrab ntawm maxilla, thiab ob lub hauv paus incisors nyob rau ntawm ob sab ntawm kab nruab nrab. Lub luag haujlwm tseem ceeb ntawm maxillary central incisors yog txiav cov zaub mov thaum lub sij hawm mastication ntawm mechanical digestion los tsim cov zaub mov bolus.
Daim duab 01: Maxillary Central Incisor
Lub cev nqaij daim tawv thiab lub cev ntawm lub hauv siab maxillary tuaj yeem piav qhia ntau yam raws li hauv qab no;
1. Labial Aspect
Qhov nruab nrab ntev ntawm lub kaus mom yuav yog 10 -11mm los ntawm qhov siab tshaj (kab tsev menyuam) mus rau qhov qis tshaj (incisal edge). Lub mesial txheej txheem ntawm lub crown yog convex whereas lub distal outline yog ntau convex. Qhov twg ntawm qhov curvature feem ntau nyob ntawm daim ntawv typal ntawm tus hniav.
2. Mesial Aspect
Lub kaus mom yog lub ntsej muag zoo li lub ntsej muag lossis daim duab peb sab. Lub hauv paus ntawm maxillary central incisor yog cone-puab. Lub apex ntawm lub hauv paus yog bluntly puag ncig zoo li.
3. Distal Aspect
Cov kab lus ntawm qhov distal thiab mesial tsis tuaj yeem paub qhov txawv zoo hauv maxillary central incisors. Lub curvature ntawm lub ncauj tsev menyuam kab yog tsawg nyob rau hauv ntau npaum li cas los ntawm lub distal nam piv nrog lub mesial nam.
4. Incisal Aspect
Lub kaus mom ntawm lub hauv paus maxillary zoo li bulkier los ntawm incisal nam. Lub crown ua raws li daim duab peb sab uas pom los ntawm cov qauv ntawm cov hauv paus ntoo khaub lig.
Dab tsi yog Lateral Incisor?
Maxillary lateral incisors yog nyob rau ntawm ob sab ntawm lub hauv paus maxillary incisors thiab lawv ua haujlwm los txiav cov zaub mov thaum lub sijhawm ua mastication. Lawv zoo ib yam li lub hauv paus maxillary incisors tab sis luv dua thiab nqaim dua li qhov maxillary central incisors.
Daim duab 02: Maxillary Lateral Incisors
feeb qhov sib txawv ntawm qhov sib txawv ntawm kev kho hniav lub cev tuaj yeem pom hauv maxillary lateral incisors.
1. Labial Aspect
Cov mesial thiab cov npoo ntawm qhov nruab nrab yog cim los ntawm kev hais lus. Lub cingulum yog qhov tseem ceeb. Cov grooves kev loj hlob tam sim no thiab koom nrog cingulum.
2. Mesial Aspect
Nyob rau hauv mesial nam ntawm lub maxillary lateral, lub crown yog luv, thiab lub hauv paus yog ntev. Qhov curvature tsawg dua thiab qhov incisal ridge yog hnyav heev. Qhov no muab ib tug tuab tsos rau lub maxillary central. Cov hauv paus hniav tshwm raws li lub khob hliav qab, thiab nws cov apical kawg yog blunt thiab puag ncig zoo li.
3. Distal Aspect
Ib txoj kev loj hlob tuaj yeem pom txuas ntxiv ntawm cov hauv paus hniav ntawm maxillary central. Qhov dav ntawm lub crown tshwm thicker.
4. Incisal Aspect
Qhov incisal nam ntawm maxillary lateral incisors zoo li feem ntau cov maxillary central thiab canine. Lub cingulum yog loj dua, thiab lub incisal ridge yog qhov tseem ceeb.
Dab tsi zoo sib xws ntawm Maxillary Central thiab Lateral Incisor?
- Ob leeg nyob hauv lub puab tsaig sab sauv.
- Ob leeg yog tshwm sim los ntawm pob txha maxillary.
- Ob leeg ua haujlwm hauv kev txiav cov zaub mov thaum lub sij hawm mastication los ua cov zaub mov bolus.
- Ob hom hniav tuaj yeem ua tau raws li qhov sib txawv xws li mesial, distal, incisal.

Summary – Maxillary Central vs Lateral Incisor
Cov hniav ua lub luag haujlwm tseem ceeb hauv kev zom zaub mov hauv cov txheej txheem hu ua mastication. Incisors tseem ceeb hauv kev txiav zaub mov. Lub maxillary incisors yog cov incisors nyob rau hauv lub puab tsaig sab sauv, thiab muaj plaub maxillary incisors - ob lub hauv paus maxillary incisors thiab ob sab incisors. Maxillary central incisors tsim thawj zaug tom qab lateral incisors. Lub crown ntawm maxillary central incisors yog dav thiab luv nyob rau hauv kev sib piv nrog cov maxillary lateral incisors uas muaj ntev thiab nqaim crown. Lawv txawv nyob rau hauv ntau yam xws li lingual yam, mesial yam, distal yam thiab incisal yam. Txawm li cas los xij, qhov sib txawv ntawm maxillary central thiab lateral incisors yog nyob rau hauv lawv lub sij hawm ntawm erupting.
