Abstract

Background:  Face is the index of mind, facial profile is considered to be as an important diagnostic tool in the diagnosis and treatment planning of complete denture rehabilitation. The distance between the mental foramen and the genion is also measured and based on the distance between these 2 stable structures the profiles can be classified for the complete rehabilitation. Materials and method: 90 anonymized lateral cephalograms of dentate subjects, comprising of 3 equal groups of Angle’s Class I, II and III, were taken for this retrospective study from the archives of the Department of Orthodontics, Anil Neerukonda Institute of Dental Sciences, Sangivalasa, Vishakhapatnam. The stress axis line was marked on the lateral cephalograms followed by the tangent from Centro masticale i.e., crista galli to the inner aspect of the chin i.e., genion. Another line was drawn from crista galli to mental foramen. The angle between these 2 lines was measured. The distance between mental foramen and genion was measured as well. The values obtained were compared with Steiner’s values and the correlation of profile analysis by both methods was statistically assessed using Pearson’s Correlation Results: Statistical analysis by way of Pearson’s Correlation revealed no significant co relation was formed between ANB angle and crista galli- mental foramen genion among subjects with class I and class III (p value of class I and class III were 0.566 and 0.681) and p value for class II of stable landmarks was 0.04 which had significant co-relation with ANB values of class II.  Conclusion: we can conclude that there is a significant variation and ease of differentiation between the class II profiles.
