Growth changes in two age groups with different malocclusions in individuals of Central India

Abstract

Objective: Comparative evaluation of McNamara's analysis in Class I, Class II, and Class III individuals of Central India in two different age groups. Materials and Methods: 240 individuals belonging to Central India were divided into two main groups: Group I comprised 120 children (10–14 years) and Group II comprised 120 adults (18–22 years). McNamara's analysis was used to assess skeletal, dental, and soft tissue parameters. Results: Statistically significant difference was found for facial axis angle, mandibular length, and maxillary length in children and adults in dental/skeletal Class I individuals. In Class II division 1 individuals, statistically significant difference was found in children and adults for maxillary length, mandibular length, and lower anterior facial height. In Class II division 2 individuals, statistically significant difference was found in children and adults in maxillomandibular difference and lower anterior facial height. In Class III individuals, the difference was in nasolabial angle. Conclusion: The growth of maxilla is usually completed by 10-14 years of age. The present study suggests that the growth of maxilla is continuous in adults, and nasolabial angle decreases with age in Class III individuals. Hence, planning of extractions in earlier age should be decided with caution.
