Ama-bracket systems abizwa ngokuthi izakhiwo ezingenakususwa, ezisetshenziselwa ukulungisa ukwephulwa komuntu. Lezi zinsimbi eziyinkimbinkimbi ezigxile emazinyo nge-glue ekhethekile, bese zixhunywe i-arc enomqondo "wokumemeza", okungukuthi, babuyela kwifomu yabo yasekuqaleni ngesikhathi sokushisa. Izinguquko esikhundleni samazinyo emgodini womlomo zitholakala ngokusebenzisa amandla okumelana nesigci esiphezulu. Eminyakeni engu-15 eyedlule, ama-braces ayengumshayeli nolwazi, kepha manje ukukhetha kuyinsimbi enkulu noma isafire - kunoma iyiphi isikhwama.
Yini ama-brasti ama-sapphika abukeka?
Yiqiniso, ama-braces okuqala ayedlulele ekubukeni okuphelele. Izigidi zabantu azizange ziqaphele ukulungisa ukulunywa ngokuqondile ngenxa yezimfanelo eziphansi zokuhleleka. Izinkulungwane zezingane ziye zathola ezinye izinto eziyinkimbinkimbi, zichitha iminyaka eminingana yenkathi enzima yesibindi enesisindo sezinsimbi emazinyo abo. Kodwa, ngenhlanhla, amazinyo asebenza phambili aqhubekela phambili ngokumane ekhuphuka kanye nemingcele futhi amabhondi anamuhla angaba angabonakali emazinyo.
Ubuhle obuhle kunawo wonke yi-braphira braces. Ngokukhiqizwa kwawo, kusetshenziswe amakristalu amasha asafire, ngenxa yalokho, ama-braces asuke ebala futhi engaphenduki lapho efika emazinyo. Ubungcweti bama-spare-bracket-systems yizinto ezilandelayo:
- zibala;
- Ungadli lapho udla ukudla noma iziphuzo zombala;
- ebusweni babo akukho ukuqoqwa kwe-plaque, okunciphisa ingozi yokuthuthukiswa kwamazinyo emazinyo afakwe ama-braces (nakuba, akudingekile ukuhlukumeza amaswidi);
- ukumelana okuphezulu kokugqoka;
- ungaphazamisi umsebenzi wokukhuluma;
- ungabangeli izinzwa ezingathandeki emlonyeni;
- encane, ukuhleleka okuhle, emaphethelweni azungezile;
- uhlelo oluthembekile lokugxila koqweqwe lwawo koqweqwe lwawo.
Okungabonakali kakhulu ama-sarfri ama-brace nge-arc emhlophe. Ngokuvamile, i-arc yokulungisa ibumnyama, i-metallic futhi, ngisho nalapho ama-brace efihlekile eveziwe efakiwe, ibonakala emazinyo. Kodwa i-orthodontics yanamuhla ikhiqiza ama-arcs akhethekile ngengubo emhlophe yokuhleleka, okwenza umklamo ungaphenduki isikhathi sonke.
Ukungalungi kwamakhanda
Yiqiniso, akukho lutho oluphelele, nolwazi olucacile lwama-sapphire, ngeshwa, futhi. Impendulo yabo enkulu kakhulu i-fragility. Ngakho-ke, okufanayo, kufanelekile ukuba uqaphele ngesikhathi sokudla nokuzikhandla ngokweqile lapho uvala ukudla okuqinile. Ukwehluleka okwesibili okuphawulekayo kwalezi zinhlelo zokubheja kuyinani eliphezulu. I-Alas, isafire elihlanzekile le-monocrystalline akuyona injabulo ebiza kakhulu. Kodwa zonke ezinye izinzuzo zisalokhu kufaka ukufakwa kwamashifi wesafire.
Zingaki amabhande esafire kuzodingeka zigqweke enye inkinga ebalulekile ekhathazayo wonke umuntu oye wanquma ukulungisa ukuluma. Ayikho impendulo engavamile, konke kuxhomeke esimweni sokukhonkolo. Kodwa ngokuvamile yisikhathi sokugqoka izinhlobo zezinhle
Umehluko phakathi kwama-brace enesiramisi nesafire
Umehluko wokuqala phakathi kwezinkampani ezimbili ezidumile kakhulu ekubukeni. Amabhande e-Ceramic amhlophe, nesafire, njengoba sesivele sithole - okusobala. I-Ceramic iqukethe i-polycrystalline aluminium oxide, ehlinzeka amandla amakhulu alowo maqhinga ngokuqhathanisa nesafire. Umehluko obalulekile yintengo - ama-ceramic ashibhile kunamafifire. Ngakho ama-brass ama-sare abukeka emuhle kunamazinyo amhlophe, ngaphambi kokuba asetshenziswe, iziguli eziningi zinconywa ukuba zenze amazinyo agcobe . Amabhande e-ceramic azobukeka emuhle koqweqwe lwawo lwawo wonke umthunzi, ngoba umthunzi we-ceramics ungalungiswa.
