The present study examines the influence of occlusal interference on the stereographically determined functional status of the back. Examinations took place in 15 healthy volunteers (all female) in whom "artificial" occlusal interference was imposed with tin foils and its influence on the spinal system measured with the Formetric system. Rasterstereography failed to demonstrate a significant or even appreciable effect due to intervention. Presently, the suitability of rasterstereographic examination for the evaluation of occlusal influences on craniomandibular or craniovertebral pain syndromes cannot be confirmed.
