The normal range of horizontal jaw position in an adult female sample. A comparison with Class II data.
Different variables for horizontal jaw position were calculated in an adult group of dental class I females. A large skeletal variation was found that was not significantly different from data based on class II samples. The null hypothesis for no difference between the various occlusion groups could only be rejected for those variables describing lower apical base relationship. The presence of a class II malocclusion may be due to an unfavourable dentoalveolar compensation rather than a basic deviation from the normal skeletal pattern.
