ABSTRACT
Background & Aim: Adolescents undergo dramatic changes in maxillary and mandibular dentoalveolar heights that hold important clinical implications. Due to greater vertical growth potential, dentoalveolar heights of adolescents can be easily manipulated and corrected. Determining how much dentoalveolar modifications might be necessary during treatment requires reference data (ie, growth standards) and an understanding of how the heights are interrelated. Hence this study was planned and designed for the assessment of upper and lower anterior dento alveolar heights, symphyseal depth and upper and anterior alveolar depth in different skeletal malocclusions. Materials and methods: A total of 150 individuals (75 males and 75 Females) in the age groups of 18to 25 years were classified into 3 groups of 50 subjects each as per their skeletal relationship in sagittal plane. Lateral cephalograms were made for each selected individuals under standard conditions. 11 linear and 04 angular parameters were measured. Data was analysed using ANOVA. Results: Lower incisor dental height was significantly different in different types of malocclusions. Maxillary depth on the palatal side showed a significant difference. Mean symphyseal depth showed a highly significant difference between the groups. Symphyseal depth had a very highly significant difference in males and highly significant difference was seen in females. The lower dento-alveolar height was significantly different in females. Conclusion: Significant differences in the lower anterior dento-alveolar heights, maxillary depths and symphyseal depths were found in different skeletal malocclusions.
