Abstract

The objective of this study was to evaluate the displacement of cranial reference points: Nasion, Sella, Basion, Porion, Orbitale and Pterygomaxillary, used in Jarabak and Ricketts cephalometric analysis, during active growth. Hundred and twenty digitalized lateral telerradiographies, corresponding to 60 patients (2 teleradiographies each one), were collected. The radiographies were taken with a minimum interval of one year between them (T1 and T2), where T1 is taken before or during the pubertal growth peack according to the cervical vertebral maturation stages developed by baccetti (CVM) I, II or III and T2 in CVM IV,V,VI (after the growth peak). Then, a previously calibrated examinator marked reference points and cephalometric measurements were taken (2 variables for each landmark). Measurements were made using craniofacial stable structures as references (stable basicranial line and Vertical T). To detect displacement in the landmark positions, t test or Wilcoxon test according to the distribution of each variable, was used to compare the data between T1 and T2. Also, comparisons were made by sex, and by initial and final CVM. All of the variables have variations between T1 y T2, but only 5 have a statistically significant difference. There were no differences between sexes and at initial and final CVM. In conclusion, all of the reference landmarks analyzed had displacement during active growth. Point Basion and Orbitale suffered the largest displacement. It is necessary to analyze the clinical implications of this displacement in order to evaluate the convenience of using alternative reference landmarks.
