Orthodontic khoom siv thiab cov khoom siv

Invisible aligners yog ua los ntawm elastic, pob tshab cov ntaub ntawv polymer, tshem tawm cov xov hlau thiab cov hlua khi ntawm cov tsoos tsoos thiab muab cov qib siab ntawm kev zoo nkauj. Cov ntaub ntawv feem ntau yog ua los ntawm kev kho mob- qib polyurethane lossis polycarbonate, nrog lub thickness ntawm kwv yees li 0.5-1.5 hli, muaj biocompatibility zoo thiab txhua yam khoom. Cov khoom siv dav dav rau kev pom tsis pom muaj xws li polymers, polycarbonate, polyurethane, thermoplastic polyurethane elastomers, thiab kev kho mob qib silicone. Cov ntaub ntawv no yuav tsum muaj cov yam ntxwv xws li siab pob tshab, zoo toughness, zoo haum rau cov hniav, thiab muab kev kho kom ruaj khov. Cov khoom sib txawv muaj cov yam ntxwv sib txawv ntawm hardness, elasticity, hnav tsis kam, thiab kev nplij siab, haum rau cov neeg mob sib txawv thiab cov neeg mob xav tau.

Cov npe tshwj xeeb tuaj yeem siv cov ntaub ntawv patented; Piv txwv li, Invisalign siv cov khoom siv SmartTrack patented, thaum Angelalign siv cov tom ntej no -tiam kho mob- qib polymer khoom MasterControl.
