1. Tsis txhob siv rau hauv qhov chaw uas yuav tshwm sim o.
2. Cov khoom tseem ceeb ntawm cov ntaub qhwv polymer / polyurethane resin txheej yuav ua raws li cov tawv nqaij thiab khaub ncaws. Thov hnav hnab looj tes tiv thaiv thaum ua haujlwm.
3. Cov khoom no yuav ua kom muaj cua sov thaum siv, thiab cov neeg siv yuav tsis xis nyob. Thov nco ntsoov tias ntau cov khaubncaws sab nraud povtseg ntawm polymer (orthopedic hluavtaws) cov ntaub qhwv lub qhov txhab, qhov kub ntau yuav raug tsim. Yog hais tias cov ntaub ntawv polymer (orthopedic hluavtaws) yog soaked nyob rau hauv dej nrog ib tug dej kub siab tshaj 30 degree, ntau cua sov yuav generated.
4. Cov ntaub qhwv kho mob ceeb toom cov neeg mob kom tsis txhob ntub cov ntaub qhwv polymer (orthopedic hluavtaws) kom ntau li ntau tau, vim tias daim tawv nqaij yuav tsis hloov mus rau hauv cov ntaub qhwv ntub rau lub sijhawm ntev.
