ResumoTwo anatomic methods are statistically compared with the implant method for superimposing serial head films in 18 subjects with metallic implants. Findings showed that the "best fit" method—that is, superimposition along the palatal plane registered at ANS—traditionally used by orthodontists, significantly underestimates the eruption of the teeth by 30% to 50%. The "structural method," which is based on the use of stable structures in the maxilla, showed no significant differences in vertical displacement of selected landmarks in comparison with the implant method.
