Abstract :

Introduction: In this clinical study the occlusal plane was established by two methods, in first method extra oral landmarks i,e superior ala-tragal line is used as a reference for establishing the occlusal plane , and in second method intra oral landmarks, commissure of the mouth and upper third of retromolar pad were used as a reference to establish the occlusal plane. And later through digital cephalometric radiograph and DICOM software the proximity of the occlusal plane to Xi point is checked. Materials and methodology: Occlusal plane was traced upto the full width of ramus, parallelism of occlusal plane to ala-tragal line is verified and the distance between the Xi point to the occlusal plane was measured using DICOM software. Results: the T- test comparison was done between control and study group.Occlusal plane established by method A method B was compared it shows the T- value of -15.470 and P- value of 0.0001. Conclusion: During the construction of complete denture the position of occlusal plane established by considering the superior ala-tragal line is similar to the position of OP of natural dentition
