Yidityaniso badla ubunzima nkqu nabantwana abancinane, kwaye isizathu soku - ukusetyenziswa ngokugqithiseleyo iilekese kunye nokhathalelo ngomlomo amahlwempu.

Ebudaleni, abaninzi ezijongene enye ingxaki: ukutshatyalaliswa isithsaba izinyo. Njengomgaqo, kwenzeka sabantu ukubola kwamazinyo ukusuka ufakelo rhoqo amatywina izinyo wayesebenzisa mlomo, utsho, ulahlekelwa umbala wayo. Ngaphandle konyango, izinyo zonakaliswe nesithsaba kuya kubangela ezininzi iingxaki: kabuhlungu basabela njani shushu, kuyabanda, imuncu kunye mnandi, nabagulayo noxinezeleko.

Izinyo izithsaba njengoko busebenzisa ukhetho ezingabizi kakhulu zezona ndlela ilungileyo ukusombulula le ngxaki. yokufaka kuphela inqanda ukubola kwamazinyo, kodwa nayo inegalelo ekomelezeni yayo. Xa ifakwe kakuhle isithsaba zamazinyo akayi kubangela ubuhlungu, kunye noluhlu olubanzi iimveliso ukuvumela ukuba ukhethe umbala ngokwendalo yomlomo.

Njengoko sele kukhankanyiwe ngentla apha, izithsaba zamazinyo ezenziwe ngezinto ezahlukeneyo. Ukubumba, metal, metal (igolide, platinum), imveliso - zonke ezisetyenziswa ngawo zabo.

ERashiya, ukuba kukade icangcisiwe ithandwa metal izizithsaba amazinyo. Oku akothusi - eziqaqambileyo shiny, yenziwe amatye anqabileyo, ukuba yindlela entle kakhulu ukubonisa ubutyebi babo. Namandla abo ufanelwe udumo - yokuba ixesha elide kakhulu.

Kodwa, hayi kudala waya ngendlela enye amazinyo ngezithsaba. Cermets - cwangciso ukuba amandla metal kodwa kubuhle ngaphezulu. Ngenxa yokuba ezi metal zeendawana isale umaleko obhityileyo yodongwe, kunokwenzeka ukuba pick up isuntswana kanye umbala omnye njengoko wayesebenzisa yendalo. Emva koko ukwahlula izinyo esempilweni ukusuka wokufakelwa bekuya kuba kwakungenzeki kwaphela.

izithsaba zamazinyo eyenziwe ngentsimbi sintered, ineendlela ezininzi. Ukongeza amandla kunye nobuhle abanazo nezinye iimpawu ezintle. Ngoko, ke ngokupheleleyo musa kunokwenzakalisa amazinyo ezikufutshane Bulelani ukutyabeka, yaye into yokuba yodongwe lugubungela ngokupheleleyo, lo gum ayikho gqitha kukudibana nabo. Ukongezelela, ubuso yodongwe, ngokungafaniyo nesinyithi ezininzi iikhemikhali zezenzi, ukuba iqinisekise ngokhuseleko wokufaka.

Nangona kunjalo, kukho metal-yodongwe zamazinyo izithsaba kunye minuses. Ngoko ke, musa ofuna ukufaka kwi amazinyo ngaphambili - iseramikhi kukhanye ngokusebenzisa isiseko emnyama. Xa umthwalo omkhulu ukutyabeka lowanyathela kude, kunye nentsimbi kwabenza - kubangele komzimba. Ukongeza, ezi amasuntswana ayikwazi lubekwe malocclusion.

Ke ezinye zeengqukuva yesinyithi-yodongwe ungomnye engcono. Nge Obusemagqabini ubunjani nobuhle imbonakalo, abaqinisekanga imali eninzi kakhulu. Ukongeza, ukuba elide ngokwaneleyo, ukususela kwiminyaka emihlanu ukuya kwishumi elinesihlanu, kuxhomekeka kumgangatho ukhathalelo.
