Iibhokhwe zibizwa ngokuba yi-orthodontic braces zeendidi ezahlukahlukeneyo, ezigqithiselwe ngamazinyo ngenxa yokuphazamiseka kwezilonda. Ngeli xesha le nkqubo isetyenziswa kakhulu kwi-orthodontics yokuxazulula iingxaki zokuluma. Ikhange ibe nemingcele yeminyaka. Kukho inkqubo ye-bracket ye-arcs egciniweyo kunye nezitshixo ezixhomekeke kuwo, ngokwenene mabakaki.
Ngubani owakhiwe inkqubo ye-bracket?
Kwaye naseYiputa yamandulo, abantu, njengokuba uyayazi, bekhathalele ngokubonakala kwabo. Kwakungekho okungafani kunye nokumomotheka. Emva koko ukulungiswa kwezixhobo ezisetyenzisiweyo ezisuka kwi-catgut, ezikude zifana nezixhobo ze-orthodontic zanamhlanje. Uphuhliso olusebenzayo lwe-orthodontics lwalukho kwi-XIX leminyaka, xa oogqirha baseMerika babumba umgcini wokuqala wezo zonke iindidi zee-bracket systems. Esi sixhobo senziwe ngamalungu ensimbi:
- arc;
- iibhubhu;
- amantonga;
- kunye nentambo, apho isakhiwo sonke sasiqhotyoshelwe kumazinyo.
Kwiminyaka emininzi, usosayensi u-Engle wazama ukusebenzisa izixhobo zakhe, ukuvavanya amandla ase-orthodontic athuthukileyo nokufunda iimiphumo emibi kunye nemiphumo emibi ephumayo kumazinyo, ama-tissue and joints. Ukususela ngoko, ukusetyenziswa kwezixhobo kuye kwaphuculwa kwaye, kude kube ngoku, le nkqubo iye yaba yinto yanamhlanje kwaye iqhubekile ngonyaka.
Iindidi zeebhonkiKukho izigaba ezininzi zezixhobo zeebhanki. Ngelungiselelo leebhonti ezinamazinyo, ziyakwazi ukuba ngumzimba okanye isilwimi. I-Vestibular yilezo zixhobo apho iifoloko zikhona phambi kobuso obubonakalayo bezinyo. Ewe, kunye neelwimi (ukusuka kwisiLatini igama elithi "lingua", oko kukuthi, ulwimi) okanye iilwimi zikhoyo ngaphakathi kwamazinyo, kwaye azibonakali kwabanye. Ezi zombini iintlobo zinemivuzo kunye neengxaki. Ngokomzekelo, ulwimi lweelwimi lunomsebenzi ophezulu, alubonakali ngxolo kunye nencoko, kodwa kunzima ukuba bafunde, xa bembethe, utshintsho lwentetho, kwaye kukho iingxaki zolwimi. Iibhondi zangaphandle azikho izinto ezintle, kodwa zingabizi kwaye utshintsho lwamahlwitha olunjalo ngonyango luphindwe ngokukhawuleza.
Ngokubhekiselele kwimiba ye-bracket system, kukho:
- OMnxeba. Kukho iintlobo zeentsimbi zensimbi: insimbi engenasinxi, i-titanium, igolide, i-alloys. Iintlobo ezimbini zokugqibela ezisetyenziselwa kwizigulane ezineempembelelo ezinobungozi kwiindawo eziqhelekileyo. Iinkqubo zombane zinokuyinto yendabuko, oko kukuthi, ngokutshintshwa kwimizuzu ye-ligatures kunye neebhola zerabha okanye ukuzimela. Le yinkqubo apho i-arc engagqityiweyo ekutshiyweni yocingo kwaye iyakwenza isilayidi kunye ne-force friction force. Oku kukhokelela kwisiphumo esiphuthumayo kwaye kukhululekile kwisigulane. Kukho ezimbini iintlobo zee-arcs zezibhonkco ezinjalo: zisebenza kwaye zingabonakali. I-downside yeenkqubo ezinjalo zixabiso eliphezulu kunezobugcisa beklasi.
- ICeramic. Zenziwe ngeekeramics, zikhangeleka ngakumbi kunezinto ezincinci kunezinyithi kwaye zingalimazi kakhulu. Bakhethwa ngokwemibala, eyona nto ifanelekileyo kunamazinyo afanelekileyo .
- Safira. Iikristali ze-sapphire ezifakelwayo ziye zenza umthombo wokudala izilo. Ziyabonakala kwaye ngoko ke ziphantse zingabonakali kwabanye. Ukunciphisa ukwehluka okwenyukayo xa kuthelekiswa nesinyithi kunye nexabiso eliphezulu.
- Udidi. Ziyinto ephezulu kakhulu kunesinyithi, kodwa iphantsi kwe-ceramic nesafire kwimicimbi ye-aesthetics.
- Plastiki. Kwiindleko, ezo nkqubo zincinci kunezinye zeekeramic, kodwa nazo zineziphumo ezintle: amandla angaphantsi, uvakalelo kwizinto ezinemibala.
- Idibeneyo .
Ubungakanani bonyango lwe-malocclusion lucacile kwaye lubalwe ngu-dokotela-orthodontist.
