Kas kardad hambaarsti juurde minna? Kas soovid, et oleks lihtsam viis ideaalse naeratuse saavutamiseks?<\/p>\n<\/div>\n

Kosmoseteaduse abil on kujum\u00e4lusulamitest (SMA) kasutusele v\u00f5tmisega v\u00f5imalik v\u00e4hendada hambaarsti juures k\u00e4imiste arvu. Nendel \u2018nutikatel\u2019 metallidel on h\u00e4mmastav v\u00f5ime erinevaid asendeid \u2018meelde j\u00e4tta\u2019.<\/p>\n

Nagu elastne pael, naasevad need p\u00e4rast venitamist v\u00f5i kokkumurdmist oma algkuju juurde. Kui neid painutada uude kujusse, siis soojuse m\u00f5jul v\u00f5tavad nad taas endise kuju.<\/p>\n

Euroopa kosmoseprogramm t\u00f6\u00f6tas need sulamid v\u00e4lja automaatsete l\u00fclitite jaoks. Peagi leiti neile aga palju kasutusalasid, sealhulgas luumurdude ravimiseks.<\/p>\n

Murdkohale kinnitatakse painutatud SMA-traadist valmistatud klambrid. Kehasoojus paneb klambrid seej\u00e4rel kokku sulguma, t\u00f5mmates luud seel\u00e4bi kokku.<\/p>\n

Need mitte ainult ei sulge murdu, vaid tugevdavad ka luud, kuni see paraneb. Samamoodi saab neid kasutada hammaste liikumise reguleerimiseks.<\/p>\n

Umbes veerand k\u00f5igist lastest peab hambaarsti juures k\u00e4ima, et parandada oma hammaste asetust. SMA-de abil on n\u00fc\u00fcd v\u00f5imalik sulgeda hammastevahelised l\u00fcngad v\u00f5i sirgendada hambaid \u00f5rnalt, kuid kiiresti. See t\u00e4hendab v\u00e4hem valu ja v\u00e4hem k\u00fclastusi hambaarsti juures.<\/p>","protected":false},"excerpt":{"rendered":"
