Iinkqubo ze-bracket zibizwa ngokuthi izakhiwo ezingenakususwa, ezisetyenziselwa ukulungisa ukuphulwa kwabantu. Ezi zixhobo eziyinkimbinkimbi ezixhomekeke kumazinyo ngeglue ekhethekileyo, kwaye zixhunyiwe yi-arc enokuthi "imemori yendlela", oko kukuthi, babuyela kwifomu yabo yasekuqaleni ngexesha lokutshisa. Ukutshintsha kwimeko yamazinyo emlonyeni womlomo kufezekiswa ngokusebenzisa amandla okumelana ne-arch ehleliweyo. Kwiminyaka eyi-15 eyadlulayo, i-braces yinto entsha kunye nolwazi, kodwa ngoku ukhetho lukhulu kakhulu okanye isafire - nasiphi na isikhwama.
Zibukeka njani iibrafu zesafire?
Ewe, iibrasi zokuqala zazingekho zigqibelele ekubonakala. Izigidi zabantu azizange zilinde ukulungisa ukuluma ngokuchanekileyo ngenxa yeempawu eziphantsi zeendlela zobugcisa. Amawaka amawaka azuze ubunzima obuninzi, achitha iminyaka emininzi yexesha elivisayo elinesininzi kunye neenki ezivalelwe ngamazinyo. Kodwa, ngenhlanhla, amazinyo aqhubela phambili ngokugqithisa kunye nemida kunye neengqungquthela zanamhlanje zingaba zingabonakali kumazinyo.
Eyona ndlela ihle kakhulu ngayo i-braphies braces. Ngenxa yokuveliswa kwazo, iifrifu ezilodwa zefafi zisetyenzisiweyo, ngenxa yoko, iibrasi ziphantse zibonakalise zingabonakali kwaye zingabonakali xa zinyuka kumazinyo. Ubungakanani bee-spare-bracket-systems zilandelayo:
- zibala;
- Musa ukucola xa udla ukutya okanye iziphuzo zokubala;
- ebusweni babo akukho ukuhlanganiswa kweplate, okunciphisa umngcipheko wokuphuhliswa kwamazinyo kumazinyo aphethwe ngamabhonkco (nangona kunjalo, akufuneki ukusetyenziswa kakubi kweesekese);
- ukumelana nokuphakama okukhulu;
- abaphazamisi nomsebenzi wenkulumo;
- ingabangela ukuvakalelwa emnandi emlonyeni;
- umncinci, uyilo oluhle, umjikelo ojikelezayo;
- inkqubo ethembekileyo yokugxininisa kwi-enamel.
Eyona nto ingabonakaliyo i-sarf brace nge-arc emhlophe. Ngokuqhelekileyo, i-arc yokulungisa ibumnyama, i-metallic kwaye, nangona i-braphile ebonakalayo ifihliweyo, ibonakala kumazinyo. Kodwa i-orthodontics yanamhla ivelisa iiplanga ezikhethekileyo kunye neengubo ezimhlophe zokugcoba, ezenza ukuba idizayini ibe yinto engapheliyo yonke into yokugqoka.
Iingxaki zeebraces
Kakade, akukho nto iphelele, kunye ne-sapphire braces, ngokubhekisayo, ngokunjalo. Ingxaki yabo enkulu kukuba Ngoko ke, konke okufanayo, kuyafaneleka ukuba uqaphele ngexesha lokutya kunye nokuba ungenzi umzamo ogqithiseleyo xa ugxotha ukutya okuqinileyo. Inkalo yesibini ephawulekayo yeenkqubo ezinjalo zesikhokelo yintengo ephakamileyo. Hayi, i-sapphire e-monocrystalline ecocekileyo ayiyinto enqabileyo. Kodwa zonke ezinye iingenelo zisaphaya kofakelo lwe-sapphire braces.
Zingaphi iibrafu eziza kufuneka zigqwekwe ngenye into ebalulekileyo ebakhathazayo wonke umntu othe wagqiba ukulungisa ukuluma. Ayikho impendulo engabonakaliyo, yonke into ixhomekeke kwisimo sekhonkrithi. Kodwa ngokuqhelekileyo ixesha lokugqoka iintlobo zezilwanyana zobugcisa
Ukwahlukahlukana phakathi kweekramisi kunye nesafire
Ukwahlula kokuqala phakathi kweendlela ezimbini ezidumileyo ezibonakalayo. Iibragi zeCeram zimhlophe, kunye nesafire, njengoko sele sifumene-ebonakalayo. I-Ceramic iqukethe i-polycrystalline i-aluminium oxide, enika amandla amakhulu aloo mabhonkco xa kuthelekiswa nesafire. Ukwahlukana okubalulekileyo yintengo - i-ceramic ixabiso elincinci kunezofihla. Ngaloo ndlela iibrafu ze-sapire zibukeka zihle kunamazinyo amhlophe, ngaphambi kokuba zisetyenziswe, izigulane ezininzi zinconywa ukuba zenze amazinyo agcobe . Iibhonki zeramic ziya kubonakala zikhulu kwi-enamel kwanoma yimuphi umthunzi, kuba umthunzi weeramics ungaguquleka.
