Nickel-titanium alloy hlau thiab titanium alloy hlau yog ob cov ntaub ntawv nrov siv hauv kev kho hniav orthodontics.Ob lub xov hlau muaj txiaj ntsig zoo, tab sis lawv txawv ntawm lawv cov khoom thiab cov khoom.
Nickel-titanium alloy hlau, tseem hu ua Nitinol, yog cov duab-nco alloy uas muaj ob qho tib si npib tsib xee thiab titanium nyob rau hauv nws muaj pes tsawg leeg. Nws muaj peev xwm rov qab mus rau nws cov duab qub thaum nws tau rhuab saum ib qho kub, uas ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv orthodontic.

Ntawm qhov tod tes, titanium alloy hlau yog cov ntshiab titanium hlau uas sib xyaw nrog lwm cov hlau xws li molybdenum, aluminium thiab vanadium los txhim kho nws lub zog thiab yoog raws. Nws raug suav hais tias yog qhov muaj zog tshaj plaws thiab ruaj khov tshaj plaws orthodontic hlau. Titanium alloy hlau yog tawv dua li Nickel-titanium hlau, uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov neeg mob uas muaj kev kho hniav nyuaj. Nws kuj tseem tiv taus corrosion uas ua rau nws zoo tagnrho rau kev siv mus ntev.
Zuag qhia tag nrho, ob qho tib si npib tsib xee-titanium alloy hlau thiab titanium alloy hlau muaj lawv tus kheej zoo nyob ntawm cov kev xav tau tshwj xeeb ntawm tus neeg mob. Orthodontists muaj peev xwm txiav txim siab qhov kev xaiv zoo tshaj plaws rau lawv cov neeg mob raws li lawv tus kheej xav tau.
