Paralelismo entre plano oclusal y 3 planos cefalométricos
Purpose
The aim of this study was to verify the parallelism between the occlusal plane defined by Ricketts and 3 new different definitions of cephalometric lines in a Chilean eugnathic population.
Material and method
A cross-sectional study was conducted on 96 Chilean eugnathic young adults between 18 and 35 years old. Lateral digital standardised cephalometric radiographs were used. The cephalometric tracings for suggested lines A, B, and C were drawn by hand. Line A extends from the junction between the palatal plane and Downs's mandibular plane to Stomion. Line B was drawn from the Ricketts's Xi point to Stomion. Line C goes from Ricketts's R3 and R4 midpoint to Stomion.
Results
The ANOVA test shows significant differences between the suggested lines and the occlusal plane. The mean angle obtained for line A is 0.42° to the occlusal plane, while lines B and C showed a mean angle of −1.71°. A correlation coefficient r > 0.7 was obtained.
Conclusion
Line A is the most parallel line to the occlusal plane. Although lines B and C show a little discrepancy with the occlusal plane, they may be used anyway.
