Rettegsz a fogorvoshoz j\u00e1r\u00e1st\u00f3l? Szeretn\u00e9d, ha lenne egy egyszer\u0171bb m\u00f3dja annak, hogy t\u00f6k\u00e9letes mosolyod legyen?<\/p>\n<\/div>\n

Az \u0171rkutat\u00e1s az alakmem\u00f3ria-\u00f6tv\u00f6zetek (SMA-k) bevezet\u00e9s\u00e9vel hozz\u00e1j\u00e1rul ahhoz, hogy ritk\u00e1bban kelljen fogorvosi sz\u00e9kbe \u00fclni. Ezek az \u2018intelligens\u2019 f\u00e9mek leny\u0171g\u00f6z\u0151 k\u00e9pess\u00e9ggel rendelkeznek: \u2018megjegyzik\u2019 a k\u00fcl\u00f6nb\u00f6z\u0151 poz\u00edci\u00f3kat.<\/p>\n

Ak\u00e1rcsak egy gumiszalag, kiny\u00fajt\u00e1s vagy \u00f6sszehajt\u00e1s ut\u00e1n visszanyerik eredeti alakjukat. Ha \u00faj form\u00e1ra hajl\u00edtj\u00e1k \u0151ket, h\u0151 hat\u00e1s\u00e1ra visszat\u00e9rnek eredeti \u00e1llapotukba.<\/p>\n

Az eur\u00f3pai \u0171rprogram az automatiz\u00e1lt kapcsol\u00f3khoz fejlesztette ki ezeket az \u00f6tv\u00f6zeteket. Hamarosan azonban sz\u00e1mos felhaszn\u00e1l\u00e1si ter\u00fcletet tal\u00e1ltak sz\u00e1mukra, t\u00f6bbek k\u00f6z\u00f6tt a csontt\u00f6r\u00e9sek kezel\u00e9s\u00e9ben is.<\/p>\n

A hajl\u00edtott SMA-huzalb\u00f3l k\u00e9sz\u00fclt kapcsokat a t\u00f6r\u00e9s hely\u00e9n r\u00f6gz\u00edtik. A testh\u0151 hat\u00e1s\u00e1ra a kapcsok \u00f6sszez\u00e1r\u00f3dnak, \u00e9s \u00edgy \u00f6sszeh\u00fazz\u00e1k a csontokat.<\/p>\n

Ezek nem csup\u00e1n \u00f6sszez\u00e1rj\u00e1k a t\u00f6r\u00e9st, hanem meger\u0151s\u00edtik a csontot is, am\u00edg az meg nem gy\u00f3gyul. Ugyan\u00edgy felhaszn\u00e1lhat\u00f3k a fogak mozg\u00e1s\u00e1nak szab\u00e1lyoz\u00e1s\u00e1ra is.<\/p>\n
