Evaluation and comparisons of steiner's analyses in Class I, Class II, and Class III patients of central India as an aid in orthodontic treatment plan

Background: Cephalometric values particular to one ethnic group may not be applicable to others. Purpose: The purpose of the study was to evaluate and compare Steiner's analyses in Class I, Class II, and Class III patients of Central India in two different age groups. Materials and Methods: Sample size comprised 240 patients belonged to Central India. Patients were divided into two main groups: Group I comprised 120 young children in age of 12–16 years and Group II comprised 120 young adults in age of 18–22 years. Steiner's analysis was done from the data collected to assess skeletal and dental parameters. Results: Central Indian patients had bimaxillary dentoalveolar protrusion, particularly predominant in Class I and Class II males and Class III females. Central Indian patients had predominant retrognathic jaws in comparison to Caucasian norms. Conclusions: The differences of skeletal and dental parameters indicate that Caucasian norms cannot be truly adhered to Central India patients during orthodontic treatment. Incisors were normally more proclined in Central Indian patients and their overretraction during orthodontic treatment would cause flattening of facial profile and therefore should be avoided.
