Ua ib feem tseem ceeb ntawm kev kho hniav orthodontic, cov hlau ligating ua tiav ob txoj haujlwm ntawm kev kho tshuab thiab kev kho tshuab los ntawm nws cov khoom siv elastic. Hauv kev xyaum orthodontic niaj hnub no, kev siv cov hlau ligating sib txawv tuaj yeem txhim kho kev ua haujlwm orthodontic los ntawm 15-20%, ua haujlwm ua qhov lav tseem ceeb rau kev txav hniav meej. Nrog kev nce qib ntawm cov khoom siv thev naus laus zis, tiam tshiab ntawm cov khoom siv hlau ligating yuav txuas ntxiv tswj lawv cov haujlwm tseem ceeb thaum hloov pauv mus rau kev txawj ntse thiab kev ua haujlwm, muab kev txhawb nqa txhim khu kev qha rau kev kho hniav orthodontic.
