This review discusses the use of 3D scanners in the production of customized orthoses. Traditional methods, such as plaster casting, are time-consuming and can cause discomfort and hygiene issues. 3D scanners offer a non-invasive, efficient alternative for creating accurate, customized orthoses. The study highlights various 3D scanning technologies, including photogrammetry, structured light, laser, and optical scanners, and their applications in orthotic design. Photogrammetry is noted as the most commonly used and suitable method for capturing human anatomy in 3D. The review also discusses the advantages and limitations of each technology, emphasizing the need for accurate data acquisition and processing. Studies show that 3D scanning improves patient comfort and outcomes, with 3D-printed orthoses being preferred over traditional methods. However, challenges remain in terms of cost, training, and integration into clinical practice. The review concludes that photogrammetry and structured light are the most suitable 3D scanning technologies for orthotic production, with ongoing research aiming to develop more efficient and cost-effective solutions. The integration of 3D scanning into clinical settings is seen as a promising step towards more personalized and effective orthotic care.This review discusses the use of 3D scanners in the production of customized orthoses.
