AIM: this study was aimed at verifying whether there are differences among the results obtained by total superimposition techniques. METHODS: a sample of 50 cephalometric X-rays from patients aged 8.25-16.25 years was used to assess the alterations that derive from craniofacial growth and development, as well as from orthodontic treatment. Cephalometric variables representative of direction and magnitude of displacements of facial-skeletal components were used to assess those alterations. RESULTS AND CONCLUSION: we concluded that superimposition techniques can produce significantly different results.
