dc.description.abstractAbstract Introduction 3D position of condyle in glenoid fossa directly affects the anterior, posterior and vertical position of the mandible. By using different techniques and measurements and also using CBCT images, the present study demonstrated the difference between the 3D position of condyle in class III pattern and the normal class I pattern. Materials and Methods In this descriptive cross-sectional study, CBCT images of 48 patients with the classI skeletal relationship and 48 patients with the class III skeletal relationship were selected. From these images sagittal , axial , coronal and 3d models were acquired by using the NNT viewer software.The patients with the classes I and III skeletal relationship were separated based on the ANB angle .The parameters (APC) and (VPC) were measured in the sagittal section. The parameters (ACA),(LLPC) and (APDC) were measured in the axial sections and the parameters (VDC) and (CCA) were measured in the coronal sections. The results were reported by using Means and standard deviations. In order to compare the 3d positions of the condyle in the classes I and III skeletal groups independent t-test was used. SPSS/20 software was used for statistical analysis and p value <0/05 were considered statistically significant. Results Among the measured parameters , vertical position of condyle ( VPC) was higher in class III skeletal patients compared to class 1 skeletal patients. The CCA parameter or the coronal condylar angle was also increased in class III skeletal patients compared to class 1 skeletal patients. All the parameters defining the 3d position of the condyle were similar among men and women in class 1 and 3 skeletal patients. The parameters were also similar between the right and left condyle in each individual patient.en_US
