CAD/CAM technology has significantly transformed orthodontic diagnosis and appliance fabrication by enabling precise digital planning and individualized bracket and archwire design. While both labial and lingual orthodontic systems benefit from digital workflows, their biomechanical characteristics, clinical efficiency, patient experience, and technical demands differ considerably. Labial CAD/CAM systems provide enhanced accessibility, predictable force delivery, and reduced treatment time due to simplified mechanics and longer inter-bracket distances. In contrast, lingual CAD/CAM systems rely heavily on extensive customization to overcome the anatomical complexity and limited access of the lingual tooth surface, offering superior esthetics at the cost of increased clinical difficulty and potentially longer treatment duration. This review provides a comparative analysis of labial and lingual CAD/CAM systems, examining their mechanics across treatment stages, clinical efficacy, treatment outcomes, and patient-related considerations. Advantages, limitations, and current evidence are synthesized to guide clinicians in making informed appliance selections based on case complexity, esthetic priorities, and operator expertise.
Key words: Labial orthodontics, Lingual orthodontics, CAD/CAM technology, Digital orthodontics, Customized orthodontic appliances
