Qhov sib txawv tseem ceeb ntawm cov pob txha basal thiab cov pob txha alveolar yog cov pob txha basal yog cov ntaub so ntswg ntawm lub mandible thiab maxilla tshwj tsis yog rau cov txheej txheem alveolar thaum cov pob txha alveolar yog cov pob txha hauv ob sab phlu.
Mandible thiab maxilla pob txha yog cov pob txha uas tsim lub puab tsaig qis thiab lub puab tsaig sab saud. Lawv yog ob lub pob txha loj ntawm peb lub ntsej muag. Lub mandible yog cov pob txha loj tshaj plaws uas tuav cov hniav qis. Ntxiv mus, nws txhawb mastication. Lub maxilla yog cov pob txha ruaj uas tuav cov hniav sab sauv. Nws tseem yog ib qho tseem ceeb hauv mastication thiab kev sib txuas lus. Cov pob txha basal thiab pob txha alveolar yog ob pob txha ntawm maxilla thiab mandible. Cov pob txha basal yog cov ntaub so ntswg ntawm lub mandible thiab maxilla, thaum cov pob txha alveolar yog cov pob txha hauv ob sab phlu.
pob txha Basal yog dab tsi?
pob txha Basal yog cov ntaub so ntswg ntawm lub mandible thiab maxilla uas tsis yog txheej txheem alveolar. Yog li, pob txha basal nyob hauv qab txheej txheem alveolar. Hauv lwm lo lus, cov txheej txheem alveolar nyob ntawm cov pob txha basal ntawm mandible thiab maxilla. Hauv lub cev mandibular, pob txha basal yog ib qho ntawm ob qhov kev faib loj. Cov pob txha basal tsim cov qauv ntawm cov hniav pob txha. Ntxiv mus, basal pob txha muaj feem ntau ntawm cov leeg nqaij. Cov pob txha basal pib tsim nyob rau hauv fetus txawm tias ua ntej kev txhim kho hniav. Qhov siab ntawm cov pob txha basal ntawm mandible thiab maxilla nyhav nce thaum laus.
Alveolar pob txha yog dab tsi?
Alveolar txheej txheem yog cov pob txha uas muaj cov hniav thiab alveoli (cov hniav vaj tse). Aleveolar txheej txheem thiab pob txha basal nyob ua ke, thiab tsis muaj kev sib cais meej ntawm lawv. Qhov tseeb, cov txheej txheem alveolar nyob ntawm cov pob txha basal. Cov txheej txheem alveolar muaj cov pob txha alveolar, cortical phaj thiab daim txhuam cev pob txha. Yog li, alveolar pob txha yog cov pob txha uas kab alveolus thiab txhawb cov hniav. Nws yog ib tug heev mineralized ntaub so ntswg. Muaj ob qhov loj ntawm cov pob txha alveolar li pob txha alveolar kom zoo thiab txhawb nqa pob txha alveolar. Alveolar pob txha tsim nyog muaj cov pob txha pob txha thiab cov pob txha lamellar. Nws feem ntau yog kab ntawm cov hniav. Ntawm qhov tod tes, txhawb cov pob txha alveolar muaj cortical phaj thiab txhawb nqa spongiosa.
Alveolar pob txha muaj 0.1 txog 0.5 hli tuab. Txhawm rau muab cov hlab ntsha thiab ntshav rau cov hniav, cov pob txha alveolar muaj ntau qhov perforations uas tso cai rau cov hlab ntsha thiab cov hlab ntsha. Tsis tas li ntawd, cov pob txha alveolar raug kho kom zoo raws li cov hniav txav thiab sab nraud stimuli. Txawm li cas los xij, qhov muaj thiab kev saib xyuas ntawm cov pob txha alveolar yog cov hniav nyob ntawm tus hniav. Qhov tseem ceeb tshaj plaws, tom qab kev tshem tawm cov hniav, cov pob txha alveolar nyhav resorb. Cov pob txha alveolar tsim los ntawm cov pob txha hniav.
Dab tsi zoo sib xws ntawm pob txha pob txha thiab Alveolar pob txha?
- Ob pob txha pob txha thiab pob txha alveolar muaj nyob hauv maxilla thiab mandible.
- Yog li ntawd, lawv yog ib feem ntawm cov pob txha mandible thiab maxilla.
Qhov txawv ntawm pob txha pob txha thiab pob txha alveolar yog dab tsi?
pob txha Basal yog ib qho tseem ceeb ntawm cov ntaub so ntswg ntawm mandible thiab maxillae tshwj tsis yog rau cov txheej txheem alveolar, thaum cov pob txha alveolar yog cov pob txha uas kab alveolus. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov pob txha basal thiab pob txha alveolar. Ntxiv mus, functionally, basal pob txha tsim cov qauv ntawm cov hniav skeletal, thaum cov pob txha alveolar txhawb cov hniav. Tsis tas li ntawd, lwm qhov sib txawv ntawm cov pob txha basal thiab cov pob txha alveolar yog cov pob txha basal pib tsim hauv fetus, thaum cov pob txha alveolar tsim los ntawm cov pob txha hniav.
Summary – Basal Bone vs Alveolar Bone
pob txha Basal yog cov ntaub so ntswg ntawm lub mandible thiab maxilla. Nws tsim cov qauv kho hniav skeletal. Cov pob txha basal muaj nyob hauv qab txheej txheem alveolar. Piv txwv li, pob txha basal yog ib feem ntawm cov txheej txheem alveolar. Nws yog cov pob txha nyias uas ua rau cov alveolus. Nws muaj ntau qhov perforations thiaj li tso cai rau cov hlab ntsha thiab cov hlab ntsha mus txog cov hniav. Yog li, qhov no qhia txog qhov sib txawv ntawm pob txha pob txha thiab pob txha alveolar.
