Influence of cranial base parameters on the mandibule in class II division 1 mal-occlusion (Three dimensional cephalom-etric study

Abstract

Aim: To evaluate the effect of cranial base parameters on mandibular parameters in class II division 1 malocclusion in three dimensions. Materials and Methods: The sample consists of 103 students age range between (18-24) years, 103 students (50 males and 53 females) having class II division 1malocclusion. Lateral and posteroanterior radiographs were taken for each subject. Cranial base measurement included (five angular and seven linear measurements). Mandibular measurement included (six angular and eleven linear measurements). Descriptive statistical analysis was used to describe the data using Pentium computer using SPSS program. Results: Cranial base flexures play a role in determination of lower jaw position which represented by significant effect of cranial base angles (
