Head orthesis therapy in infants with unilateral positional plagiocephaly: an interdisciplinary approach to broadening the range of orthodontic treatment

Objective Unilateral positional plagiocephaly is the most common deformity of the head in infants. As part of a prospective controlled clinical study, the pathomorphology of the positional plagiocephaly in early infancy was examined. The goal was to use noninvasive three-dimensional (3D) imaging to generate, for the first time ever, a standard database of infants without head deformities, to quantify the asymmetry of the positional plagiocephaly, and to evaluate the effectiveness of functional growth control using head orthesis.
