Background: Complete denture construction is a product of biological sciences as well as sound mechanical principles. Correct orientation of the occlusal plane plays a vital role in achieving optimal aesthetics, occlusal balance and function of complete dentures. The occlusal plane is normally established anteriorly according to aesthetics of patient and posteriorly parallel to camper?s plane. This study is done to establish the effect of age and ala-tragal line. Aim: The purpose of this study is to evaluate relative parallelism of the occlusal plane to the different tragal levels of the ear Materials and method: A total of 25 subjects with complete denture between the age group 18-25 years were selected. Fox plane was placed intraorally covered with dental wax, between their natural teeth, so that it touched incisal edges of upper incisors and cusps of left and right upper first molars and the subjects were asked to hold fox plane in this position. Left lateral profile photographs were taken with subjects in natural head position with their back straight. Result: The relationship between the occlusal plane and the inferior border of ala-tragus was about 76%. The inferior border of the ala-tragus line was almost parallel to the occlusal plane when considered as posterior reference point in young adult age group. Conclusion: The inferior border of the ala tragal line is suggested as the best posterior reference point in younger age individuals. Keywords: complete denture ,occlusal plane , posterior reference point , ala tragal line.
