Digital vs. Analog Inputs in CAD/CAM Orthodontics: A Comparative Clinical Evaluation of Palatal Expander Fabrication Workflow

Starting soon

Conditions studied: Transverse Maxillary Deficiency

In brief

36 patients with unilateral or bilateral cross bite treated with hyrax expanders fabricated through three distinct workflows: fully conventional (physical impression + manual fabrication), hybrid (physical impression + CAD/CAM fabrication), and fully digital (intraoral scanning + CAD/CAM fabrication). To evaluate and compare the clinical fit, workflow efficiency, and patient/clinician satisfaction of palatal expanders fabricated using traditional, hybrid digital, and fully digital workflows.
