Zingaphi kwamazinyo zabantu? Zingaphi amazinyo umntu itshintshile? Inani amazinyo ubisi umntwana

Namhlanje siza kukuxelela ngokweenkcukacha mangaphi amazinyo abantu, ngokunjalo wamxelela malunga nesakhiwo yabo, imisebenzi, iintlobo, njalo njalo.

Overview

Amazinyo owabumba bone ibekwe kwisisu yomlomo kwabantu. Bona zibekwe ngendlela jike 2 (omnye ngaphezu komnye). Ukuba umntu somknet aphantsi kunye nemihlathi aphezulu kunye, amazinyo zivaliwe, yahlukanisa kwisisu buccal of kwisisu yayo. Kule ziluma kwakhiwa meko abantu, nto leyo ufundwa inzululwazi ezifana orthodontics.

amazinyo Healthy - nto leyo omhle omhle yonke eziphilayo. Noko ke, abantu abaninzi nje ufuna ukubonisa imeko bakhe emzimbeni, kodwa uncumo ezintle nekhephu-ezimhlophe. Kwaye into esiyenzayo, siya kujonga ekupheleni.

Iifom iintlobo ezisisiseko kwamazinyo

Phambi ndithi indlela abantu abaninzi babe amazinyo, kufuneka ufumanise ukuba kanye indlela zahluke ifomu kunye nenjongo. Ngapha koko, wonke izinyo single yenza kuphela imisebenzi, ezizezi kuthinjwe ukutya, uyibambe emlonyeni wakho ukuhlafuna. Kufuneka kuqatshelwe ukuba abanenxaxheba ngokuthe ngqo indlela echanileyo yokubiza izandi.

bathezi

Ezi amazinyo zisezindaweni phambi తీసివేయి Susa (4 ngasentla nangasezantsi inani elifanayo). Igama lakhe bakuchazele yokuba babe elidlula elibukhali ngendlela apho umntu lula nomntana off naziphi iimveliso, kuquka entle ezinzima.

canines

On omabini amacala siphume xa abantu amazinyo cone-ezimilise, okanye ebizwa ngokuba "canines" (2 phezulu nasezantsi isixa esifanayo). Ezi nkundla ke zenzelwe ukuba basike iingceba yonke imveliso. Kufanele kuphawulwe ukuba ezi ndidi amazinyo zabantu kunokuba okwanamhlanje eseliphuhlile izilwanyana-ngamarhamncwa. Oku kubangelwa yinto yokuba abantu musa ukusebenzisa ukutya okunjalo ekrwada, baberhabaxa kwaye ezinezikhondo, efana nenyama.

imihlathi Small

Ukuziqhelisa lwezonyango, ezi amazinyo ekuthiwa premolars. ohlafuna umphezulu labo tubercles ezimbini. Ke zona iingcambu, ngoko isenokuba omnye okanye emibini apho. imihlathi Small ukuze umntu kwasani iimveliso, kwakunye lokugaya ngakumbi. Ngaphezu koko, premolars zinokusetyenziswa ukukrazula ukutya.

imihlathi amakhulu

amazinyo thaca, ibekwe kwi ezisezantsi kwemihlathi yangasentla kuthiwa imihlathi. Ngokungafaniyo ukubunjwa bone edlulileyo, bebona izinto ngobukhulu ezinkulu, kwaye ingcambu ngaphezu kwesinye (ezintathu kwaye top ezantsi - ezimbini). Ngaphezu koko, kufuneka umphezulu ihlafuna kunye vee ezizodwa, ezo zibizwa ngokuba ukuqhekeka. Kwakhona ezincotsheni imihlathi, kukho tubercles ezine okanye ezintlanu. Eyona umsebenzi imihlathi - a ukugaya ukutshabalalisa ukutya kwi ido- phambi kokungenisa ngqo.

Ngoko ke zingaphi imihlathi ebantwini? Inani premolars ezivela kubantu abasempilweni liphezulu ezine inani elifanayo emazantsi. Ke ukuba imihlathi, inani labo ngokufanayo ezincinane.

amazinyo imihlobo

Kufuneka kuqatshelwe ukuba umntu iiseti ezimbini amazinyo: yethutyana okanye esisigxina. Ngokutsho isakhiwo kunye nemisebenzi ziyafana kakhulu omnye komnye. Noko ke, ubungakanani ukuyilwa ithambo okwethutyana zincinane kwaye ube ngumthunzi eyahlukileyo (white-esiluhlaza). Hi ndlela leyi, zibizwa ngokuba "ubisi."

Kuphuhliso kwamazinyo zamabanga esisigxina, badlala kakhulu indima ebalulekileyo. Ngapha koko, imfundo ezifana abantwana kugcina isithuba eziyimfuneko ukuze siphume elizayo, canines, premolars kunye imihlathi, kwakunye walathise ukukhula ngakumbi. Kubalulekile ukuqaphela ukuba inani amazinyo ubisi ebantwini yi iziqwenga-20 kuphela. Baya kudla baqale qhuma kwiinyanga malunga 3-6, nokuba ukushiya ngokupheleleyo kweminyaka emi-2,5 okanye 3.

Ukwazi kakuhle kangakanani amazinyo ubisi umntu kufuneka aye inkcazelo constants. ludla ziqala ukubonakala kwasekuqaleni 5-6 iminyaka kwaye endaweni ngokupheleleyo ixesha kwiminyaka 12-14. Imihlathi yokuqala ikhula kwisithuba emva yobisi. Xa lixesha, iingcambu ixesha Zubikov ebantwaneni ukunyibilika kwaye ekugqibeleni uwe. Njengoko yaziwa, le nkqubo lwenzeka ngokwezibini kwaye ngokulandelelana.

Ngoko ke, impendulo umbuzo malunga zingaphi amazinyo kutshintsha umntu, aze abe mzobo 20. kakuhle Emva bonke, njengokuba abaninzi Zubikov yobisi iwela kubantwana abaselula, kwaye kwixesha elizayo endaweni kubo bekhula siphume abasisigxina, canines njalo njalo.

32 - yamihla le?

Buza umbuzo wakho wamazinyo ukuba abantu abaninzi babe amazinyo, uyakwazi uve kakhulu impendulo ecacileyo: 32. Eli nani yenziwa yiNdlu yoWiso-manani ilandelayo:

• 8 bathezi (4 kubo ibekwe emhlathini ezisezantsi-4 - phezulu);
• canines 4 (2 ngasentla kwaye enye ngezantsi);
• 8 premolars (4 ngasentla 4 ngezantsi);
• 12 izinyo (yesithandathu maxilla kunye nenani elifanayo kwi emazantsi).

Noko ke, abanye abantu ekuthini izinyo wabo, badla bakwate kuthekani ezibonisa kwi-28 endaweni ye 32 Oku kungenxa yokuba imihlathi, zikhula ukuya kwiminyaka-14 ezibumba izibini emhlathini ephezulu nesezantsi-2 kuphela, ngokulandelelana. Ngamanye amazwi, inani imihlathi yabantu abanempilo kukho ncam nabancinane (oko kukuthi, iiPC-8.). "Ngoko ke apho abanye 4?" - ubuze. Into yokuba inani elipheleleyo amazinyo umntu kuqwalaselwa kunye amazinyo ekuthiwa "ubulumko". Ngokuqhelekileyo, ezifana ukuyilwa kwamathambo abantu akhule ukusuka kwiminyaka eli-17 ukuya kwengama-30 ubudala. Ngaphezu koko, abangenakuze babonakale, ukwenza inani 32 akunjalo eqhelekileyo.

Kuninzi amazinyo ubulumko ebantwini? Phendula umbuzo, uya kuba nako ukubala elula zezibalo:

32 (a inani eqhelekileyo amazinyo) - 28 (kwamazinyo isigxina, nto leyo ikhule ukuya kwiminyaka eli-14) = 4 amazinyo ubulumko, ezimbini kuzo ibekwe ngasentla nangasezantsi efanayo.

Njengoko kukhankanyiwe nje ngentla, loo ukuyilwa ithambo akanakuze ukukhula. Le nyaniso kukuba ngenxa yokuba ngethuba ngendaleko ngokungeyomfuneko ngenxa ukuhlafuna imihlathi kancane kancane. Ngokutsho manani, iseti epheleleyo jike ezimbini emhlathini ezisezantsi neziphezulu izibophelelo, kukho kuphela isiqingatha sabantu emhlabeni wethu.

nomlando nokukhangela ukuba elizayo

Ukuba umbuzo indlela abantu abaninzi babe amazinyo isetwa kwixesha elidlulileyo elikude, bekuya ndamgocagoca inani ezahlukeneyo ngokupheleleyo, kunokuba 32 Ngapha koko, ookhokho bethu wesiseko wethambo em- ngomlomo baba baninzi-44, oko kukuthi kanye 12 Zubikov ngakumbi. Ekuhambeni kwexesha, kunye kwicala ngalinye eliphezulu umhlathi asezantsi shwaka ngababini eziliqela amazinyo.

Ngokutsho kweengcali, kwiminyaka elikhulu embalwa, abantu kwakhona kuyacuthwa imihlathi yesibini neyesithathu, kwakunye siphume lateral. Oku kungenxa yokuba indoda mihla liya utya kuphela izidlo ezithambileyo kunye mushy ukuba ehlafuna ongazifuniyo ukuyilwa ithambo ikhankanywe ngasentla. Hi ndlela leyi, lingakwazi kuchaphazela into yokuba emhlathini yabantu ngcembe uya kuba lincinane. Kakade ke, kufuneka itshintshwe ezi nguqu kwindaleko. Kodwa ke kule meko kufuneka banikwe umthwalo owongezelelweyo kuyo yonke le nkqubo kwamazinyo. Ukuze wenze oku, umntu kufuneka atye isilwanyana okanye ukutya irhabaxa abatya.

Ubume izinyo

Zingaphi amazinyo kubantu abadala, safumana ngaphezulu kancinane. Kodwa ethetha loo iimanyano bone abantu badla yonke imihla nokunika umzimba wakho ngazo zonke izinto eziyimfuneko, ungenza kugqitha ubume babo.

Njengoko usazi, le nto iquka la macandelo: isithsaba, entanyeni kunye neengcambu.

1. "Crown" libhekisela inxalenye ebonakalayo izinyo, nto leyo isale lwawo (iziyobisi inzima emzimbeni womntu), ukumelana noko zaphuka.

2. Le intamo inxalenye izinyo antywiliselwa kulo intshungama.

3. ingenangcambu izinyo ise ngqo kwi ithambo emhlathini.

Kufuneka kuqatshelwe ukuba isambuku emelweyo ukuyilwa ithambo oyinxalenye babizwa ngokuba "dentin", ibekwe phantsi lwawo. Le nto kahle ixesha elide. Noko ke, besenza zaphuka, nobulukhuni xesha nganto isithsaba. Njengoko yaziwa, dentin okugcwele imijelo ezininzi equlathe iinkqubo iiseli ukusuka apho, enyanisweni, na.

Ngokumalunga lweHo- izinyo, oko kuquka kwalapho kunye imithambo yegazi. Beninikela zonke izondlo eyimfuneko eziphilayo wesiseko bone kwaye susa iimveliso zabo inkunkuma.

Ukuya emva iingcambu, kufanele kuphawulwe ukuba sigqunywa ngokupheleleyo lwesamente. Le nto iyafana namathambo yesiqhelo. Kuyinto kule yinxalenye izinyo eqhotyoshelweyo imicu multiple ukuba uyibambile (kwi gingiva). Noko ke, ezinye ukuhamba wesiseko ithambo lisekhona. Eneneni, ngenxa oku kunciphisa ngokubonakalayo amathuba okuba ukuba ndiya kuyaphula ngexesha ukuhlafuna ukutya okuqinileyo.

Bambalwa abantu bazi, kodwa yonke izinyo yabantu umngxuma, zona zikhoyo ka ku kuso aka ijelo, kwaye kukho umngxuma omncinane ezincotsheni zazo. Njengoko yaziwa, le sithuba umngxuma izaliswe-ekuthiwa "ido-". Kwaba emihlathini zakhe angene phakathi kwalapho kunye neempahla ezahlukeneyo.

Indlela yokunyamekela amazinyo akho?

Ukuba ufuna ukugcina yonke 32 izinyo (okanye 28), ngoko ukuba babe ngononophelo wakhangela emva. Ukuza kuthi ga ngoku, iingcali bacebisa ngokuhlwa kwaye kusasa ukucoca kakuhle, kwaye qho emva kwesidlo qiniseka ukuba ngamanzi emlonyeni. ucoceko Personal ziya kukuvumela ukuba ugcine yonke amazinyo akho ukuya ebudaleni. Kodwa ke ukuba ngenxa yaso nasiphi na isizathu izinyo bemilenze yakho, kwaoko kufuneka uqhagamshelane wamazinyo wakho. Hi ndlela leyi, kucetyiswa ukutyelela ubuncinane kabini ngonyaka. Ngenxa ukuthintelwa yidityaniso kunye nezinye iingxaki namaqonga ithambo iindleko buhlungu kangako kwaye ibiza ngaphantsi unyango elide kabuhlungu.
