Traditional expanders mainly provide lateral expansion; this appliance adds anterior and vertical movement with soft pressure distribution for facial symmetry.
Al2O3 sandblasting and phosphoric-acid etching create a rough, microporous tooth surface for stronger veneer fixation.
Randomly oriented inorganic fibres and particulate fillers help a dental composite balance extrusion-friendly viscosity with mechanical strength.
Structured light captures tooth surfaces while OCT maps subsurface structures, enabling aligned 3D dentition models without gingiva manipulation.
