Igama amazinyo ebantwini. Isihloko amazinyo (scheme). Amagama amazinyo avuthulukayo

Amazinyo ungomnye amalungu oluntu ibalulekileyo inxaxheba kwinkqubo yokwetyisa. Ukungaluxabisi unonophelo kwabo kunye neengxaki zempilo. Ngoko ke kubaluleke kakhulu ukuba uyazi ngokuseka bone kangangoko kunokwenzeka. Umxholo wale kwakhona iza kuba igama kwamazinyo.

Intsingiselo kwamazinyo ebantwini

Ukonyulwa amazinyo emzimbeni zabantu ulungiso ukutya, ndaliqoba, kwaye kubanjwa ngexesha lenkqubo isidlo. Ukongeza, badlala indima ebalulekileyo isandi inkqubo yokwenza into ephathelele ukuyilwa zentetho. Umntu akufuneki silibale malunga umsebenzi kubuhle.

Umntu amazinyo abolileyo kwenzeka sinesiphene ukudla zaseprayimari, apho phantsi kweemeko ezithile kunokubangela zizifo ezahlukahlukeneyo phecana zesisu. Ukongeza, umonakalo luvo Idla yintlungu enkulu kakhulu, benza kungabi lula ubomi ngokupheleleyo kwaye ibe nemveliso. Buccal uvuleke amazinyo enesifo isebenza eya kumda wesangqa wokosuleleka ephilayo. Ngena inkumbula yeentsholongwane amalungu phecana sokuphefumla. Ekugqibeleni, abantu abaninzi nje ezingemnandi ukuba Elucweyweni abantu amazinyo abolileyo, ngubani ivumba umoya ombi.

Ngoko, ukunyamekela kwisisu ngomlomo kufuneka abe imisebenzi yemihla ngemihla yokuziqhelisa lomntu ngamnye. Ukuze wenze oku ubuncinane kabini ngemini kuyimfuneko ukucoca amazinyo ukucola, uze wenze ezinye iinkqubo eziyimfuneko lwezempilo.

Kulo mba, indima ebalulekileyo edlalwa izinga lolwazi loluntu ngendima ukuyilwa amathambo, ubume kunye nendlela ukubanyamekela. Ngoku sifunda igama kwamazinyo ebantwini.

iintlobo amazinyo

Ngaphandle kokukhetha, zonke amazinyo endalo abantu zohlulwa ngokwendidi ezimbini: yobisi kunye zomthonyama.

Eyokuqala kwezi zezomzuzwana. Dairy - ligama amazinyo zomntwana. Babonakala ngcembe emva kokuzalwa. Kwiimeko ezizodwa kakhulu, usana sele bazalwa kunye amazinyo ubisi. Ba okwethutyana emva kwexesha elithile zophuhliso ukuwa. Igama kubo ngenxa yokuba aqalile kuvela kwixesha xa usana kondliwa ubisi unina wakhe.

Zemveli - ligama amazinyo yabantu, ezithi ngokubuyisela ubisi. Ba esisigxina yaye emva kokuba umonakalo okanye ilahleko awuphinde-ukukhula. Ngoko ke, simele sikhumbule ukubaluleka inkqubo yokhathalelo nje olu hlobo amazinyo, okuyinto ngokwaso ihlaziywe.

Zalisa replacement engcanjini amazinyo lokuqala lwenzeka phambi kweminyaka womntu. Ukongeza, zikhula kweli xesha, nto leyo ayifumaneki phakathi yobisi.

iintlobo amazinyo

Ukongeza iintlobo amazinyo abangabantu zohlulwa ngokwendidi. Eli candelo kungenxa yesakhiwo imisebenzi eziyenzayo. Ngokuhambelana uhlobo oluthile amazinyo kwakhiwa igama - canines, imihlathi, premolars, siphume.

Ngu bathezi emnandi iimpawu ziquka ukupheka, aso - ukukrazula layo, premolars - Urhintyelwe, kunye imihlathi - ukugaywa.

తీసివేయి Susa

Ngenxa yoko, siye sizimisele, ngokutsho zenye uhlobo, igama kwamazinyo. Scheme indawo yazo kuthiwa ifomula kwamazinyo. Kubhaliwe ngokohlobo amabinzana exube, kodwa ingabonakaliswa ngendlela lomzobo.

Le ndlela yokubala zamazinyo umntu okhulileyo umntwana amazinyo nosana ezahlukeneyo. Oku kakhulu zendalo. umahluko omkhulu khona phakathi తీసివేయి Susa ukusuka iintlobo ezahlukeneyo zezilwanyana.

Inani amazinyo emiselwe ukuba umhlathi ngamnye isiqingatha. Kwiimeko ezininzi, ngamnye imihlathi unalo efanayo amazinyo, Kakade ke, ukuba abathanga bangenwe umonakalo okanye izifo.

Le ndlela yokubala yamazinyo lwempilo oqolileyo yabantu ngolu hlobo lulandelayo:

I2 ÷ 2-C1 ÷ 1-P2 ÷ 2-M3 ÷ 3.

Kule formula, iileta ukuchaza iintlobo ezithile amazinyo (I - siphume, C - canines, premolars P-, M - imihlathi). Nedinomineyitha linani amazinyo aphezulu, kwaye kwinani - yasezantsi.

Thelekisa izinyo elephant ifomula. Kuya kukhangela ngolu hlobo:

I1 ÷ 0-C0 ÷ 0-P3 ÷ 3-M3 ÷ 3.

Njengoko ubona, esi isilwanyana isibini ongentla siphume kunye ezisezantsi azikho kwaukubakho. Yena engafanelekanga aso. Kodwa kunokuba kukho indlovu kwi kwemihlathi ngalinye enye iperi premolars ngaphezu kokuba umntu. Kodwa ke inani imihlathi ukuba Ndikulinganise. mahluko ezincinane ukusuka olungumgubo zamazinyo kwabantu imizobo data zeminye imibutho zezilwanyana.

Igama amazinyo zaseprayimari abantwana

Siqala ngohambo kunye amazinyo ubisi igama. Umntwana on kwemihlathi ngamnye kukho ezimbini mgawuli series, siphume ezimbini osecaleni, imihlathi ezine, canines ezimbini. Kulo mba, igama amazinyo oonyana akukho kwahluka abadala. Umehluko omkhulu phakathi fomyula - isixa-ukubunjwa ithambo. Umntwana amazinyo ezilishumi zaseprayimari kwi kwemihlathi nganye, bonke - mabini. Xa abadala, 32. zabo kuphela ukuba esisigxina. Apha, mhlawumbi, umahluko kuphela. Yonke enye into - ngokufanayo (ifom, umsebenzi, isihloko amazinyo). Ilungiselelo ukujikeleza izinyo labantwana lisezantsi.

Umhla Ukukhululwa amazinyo avuthulukayo

Ngoku masifumanise kungekudala indlela kuvela iindidi ezithile amazinyo ubisi.

Amazinyo esezantsi esembindini kuvela nomntwana ophakathi kweminyaka leenyanga ezintandathu ukuya kwezisixhenxe, le siphume ephezulu kumbindi - iinyanga ezisibhozo ukuya ezisithoba, kwicala top - ukususela kwiinyanga ezilithoba ukuya elinanye, kwicala ephantsi - ukusukela kwiinyanga ezilishumi elinanye ukuya alishumi elinesithathu. Eliphezulu aphansi imihlathi yokuqala - ukususela elinambini ukuya kwiinyanga ezilishumi elinesihlanu; aso - iinyanga ezilishumi elinesibhozo ukuya kumashumi amabini. imihlathi yesibini adlabhuke yakutshanje. imbonakalo yazo kufuneka kulindelwe kwisithuba seminyaka-2 ukuya kwemi-3.

Noko ke, ukuba abathile izinyo anqamka phambi okanye emva kwexesha imida bathi, oko akujongwa kushenxwe kulo mmiselo.

Ixesha kwamazinyo esisigxina

Ukutshintshwa amazinyo zobisi kaninzi kakhulu uqala siphume. Kodwa maxa wambi phambi ukhule ukuba imihlathi yokuqala, ubisi alufumaneki. Phakathi kwazo Esi siganeko kwenzeka kwiminyaka emithandathu ukuya esixhenxe. Emva koko ke ukutshintshwa ngokuthe ngcembe amazinyo avuthulukayo rhoqo. umntwana ngamnye sele ixesha yabo yale nkqubo, yaye imithetho ecacileyo alukho. Ekupheleni imihlathi slotted yesibini neyesithathu (okanye imihlathi). Ukuba yokugqibela kuvela kule elinanye - iminyaka elishumi elinamithathu, imihlathi yesithathu qhuma emva elinesithandathu. Zibizwa amazinyo ubulumko kwaye kwenzeka phantse naliphi na inqanaba lophuhliso loluntu emva kokuba le yobudala.

Ilungiselelo ukujikeleza kwamazinyo esisigxina

Emva safunda igama amazinyo yomntwana, kwii-arhente ezinika Wabaguqukela ekubhekiselwe kuyo abadala. Amazinyo asisigxina ziquka ezine incisor engundoqo, ezine incisor yesibini, canine ezine, premolars asibhozo kunye imihlathi ezisibhozo. Kuphela amazinyo amabini anesibhozo.

Ukongeza, xa ubudala elipheleleyo kuyilwa kwi imihlathi esinye ngaphezulu - amazinyo ubulumko senditshilo. Igama kungenxa yokuba kuvela uninzi Kwiimeko umntu emva kweminyaka eli-18. Oko kukuthi, ngexesha xa wafumana amava ezithile zobomi. Amaxesha amaninzi ngenxa yokuba ukukhula amazinyo ubulumko kubangela ubovu nangokurhala, kufuneka zisuswe. Sekunjalo, lo kunokuba olukhulu bamazinyo yokwamkela azisoloko asebenzise. Kwezinye iimeko, umntu uya ukwanda phantse mntu kulo izinyo "kakhulu". Phantsi kwezinye iimeko, unyango emiselweyo.

izinyo nokwakheka

Le izinyo yahlulwe iinxalenye ezimbini eziphambili - isithsaba kunye neengcambu.

Crown - le nxalenye ebonakalayo, Bathiwe wambu lwawo, olukhusela ukuyilwa ithambo ngu ngoomatshini kunye nezinye umonakalo. Oku kulandelwa umaleko dentin. Nguye lo inxalenye ephambili izinyo elinoxanduva ngamandla alo. Emva dentine kufuneka ndaqina umaleko egubungele ingcambu izinyo.

Izithsaba ihlanganisa - ukutya ebambe ngqo, ukukrazula yayo, ukuhlafuna yaye isila, kuxhomekeka kuhlobo ngezinyo.

Root - inxalenye izinyo, leyo asikwazi ukubona ngeliso lenyama. Le ibekwe ngezantsi kwinqanaba gum. Igama iingcambu amazinyo ingqamana igama yezinyo laso. Ngoko ke khumbula ngqo akuyomfuneko. I enjalo ngokupheleleyo amalungiselelo inxalenye edityanisiweyo njengoko yintlama, imicu-luvo, neempahla esimbaxa iinqanawa lwemithambo, unyothule isamente, ingcambu kolunye, foramen apical. umsebenzi wayo ophambili anikwe izinyo ngokusebenzisa inkqubo yokujikeleza umzimba, kwakunye attachment yayo emhlathini.

imisele iingcambu - ligama yemijelo. Kumnandi ke kubo izondlo kuvuka umzimba phambi kwethu. Okwangoku zabelwe iindidi ezisibhozo imisele iingcambu, leyo ababizwe amanani lwabo.

Yezinyo ngokwawo, Noko ke, licandelo le mbono ngokubanzi. Kunye eludongeni intlaka alveolus kwaye periodontitis ukuba umzimba izinyo.

bathezi

Emva kokuhlolisisa le kwamazinyo bamazinyo, kunye namagama yesakhiwo, ingqalelo iintlobo ezithile. Makhe siqale siphume. Yiyo nale hlobo kwamazinyo yomfowunelwa wokuqala ukutya. Man ithumba ukutya kunye ubaphulelayo. Ngezi misebenzi ngabathezi ngenxa nolwakhiwo lawo elikhethekileyo. Zinelungelo imilo basike. Ububanzi siphume eliphezulu liphindwe kabini yasezantsi. Badlala indima ebonakalayo ngakumbi xa ihlafuna wokuqala ukutya.

Umntu uye siphume ezimbini umhlathi ngamnye.

canines

Emva kokuba mgawuli ukutya nokusebenza ethunyelwayo canines. umsebenzi wawo ukuba ndimaphule ukutya ukuqhubeka lula yayo makusetyenziswe ezinye iintlobo amazinyo begaya.

Ubume bale canines zikwazi ukwenza imisebenzi yazo. Baye ifomu ngokuqatha zonke amazinyo zabantu. Inxalenye engundoqo ukusebenza ye canines aba elidlula. Eyona special kukuba canines eliphezulu ezinkulu kuno 'asebenza' zabo asezantsi.

Olu hlobo kwamazinyo isibini ngasinye kwemihlathi yabantu.

premolars

Le premolars zibizwa ngokuba imihlathi ngokwahlukileyo ezincinane. imisebenzi yabo iquka pinched kwaye rivaleleke kukutya. Mu kuya kwa nshita siphume kunye canines, premolars kuba akukho namnye, kodwa neengcambu ezimbini. Kwisiqingatha ngasinye yomhlathi ubani imihlathi ezimbini ezincinane. Eyokuqala kwezi ukufana ethile kunye canine kunye yesibini - kunye imihlathi. Kwaye ke bicuspid lokuqala mkhulu kancinci kuneyesibini. Njengazo zonke ezinye amazinyo abantu, premolars ngakumbi kunalawo asezantsi.

imihlathi

Imihlathi ngenye eyaziwa ngokuba imihlathi ezinkulu. Bona ebekwe ezikude ukusuka premolars ukuya elunxwemeni emhlathini. Iinjongo zolu hlobo amazinyo sokusila ziquka ukutya lokugqibela. Eli nqanaba yokugqibela machining zayo endleleni eya kuvuleke iminxunya emathunjini. Ukongezelela neziphumo ezibonakalayo kuphela, razmyakaniyu ukutya ikhuthaza exposure namathe. Ngoko ke, ngaphambi kokuba emphinjeni, ukutya kuthatha uhlobo a oluludaka.

Imihlathi inkulu kune premolars. Baye cube ngokukhawuleza kakhulu. Ukongeza, kuba iingcambu ezintathu. I eliphezulu elikhulu Amazinyo izinyo, njengesiqhelo, ngakumbi kunalawo asezantsi.

Uphawu lwe imihlathi kukuba inani labo ongaphathiswanga ngokucacileyo. Oku kunokwahluka ukusuka ezine ukuya amathandathu umhlathi ngamnye. Kungenxa yokuba akumanqanaba ahlukeneyo ubomi bomntu nga ukukhula kwenye imihlathi ekupheleni iseti amazinyo. Njengoko kukhankanyiwe ngasentla, ngokuseka zibizwa ngokuba amazinyo ubulumko, kwaye kwezinye iimeko ukuba isuswe.

It is on imihlathi kwaye kwengalo తీసివేయి Susa kwabantu.

ucoceko Oral

Kakade ke, ukuthotyelwa kwemithetho lococeko le kwisisu somlomo kubaluleke kakhulu ukuba eqhelekileyo yokusebenza umzimba uphela nenkangeleko balo.

Inkqubo yemihla ngemihla izinyo ihlamba paste okanye gel kufuneka inyanzelekile, kuba kuchaphazela impilo yabo nje kuphela, kodwa impilo yonke eziphilayo. Okokuqala, ukubola kwamazinyo eyingozi, izinyo wayesebenzisa azitshabalalise ngokwalo. ingozi enkulu kwimpilo yelungu yamazinyo nabo isifo periodontal, gingivitis, ukubola kunye nezinye izifo.

Ukongeza, njengenyathelo lokuthintela kuyimfuneko kabini ngonyaka utyelelo wamazinyo.

Kakade ke, igama kwamazinyo ukuba enze zothintelo iinkqubo ulondolozo kunye nokhathalelo andazi ngokuyimfuneko, kodwa iinjongo zemfundo ngokubanzi, olu lwazi alukwazi buhlungu, kodwa koko, iya kuba negalelo ekufundiseni ngezempilo phambili yabemi.

imiphumela ngokubanzi

Kule ngxelo, siye safunda nje igama amazinyo, kodwa eziqhelekileyo kunye nesakhiwo kunye nemisebenzi. Oku kufuneka ukwandisa kakhulu ukuqonda inkqubo zokwetyisa xa iyonke. Ukongeza, kwagxininiswa lwabekwayo uluntu ngokubaluleka kococeko yomlomo impilo yabantu.

Le entsokothileyo olu lwazi siqaqambisa imbono jikelele abantu, yaye ngokukodwa - ukuqonda ukubaluleka lwempilo yamazinyo kubomi zomntu ngamnye, kwaye zifuna ulondolozo ngenyameko kubo.
