Background: Orientation of occlusal plane is one of the most important clinical step in removable partial denture patients. Accurate establishment of occlusal plane and the effect of its inclination on function, esthetics and speech, a method to guarantee the success of removable partial denture. Material and method: A CephalometricStudy was carried out in 15 subjects of age group from 20 to 25 years from YCMM &RDF’S Dental College Ahmednagar. Barium sulfate was used to mark ala tragus line in which anterior reference point is lower border of the nose and posterior reference point was superior, middle and inferior surface of the tragus.Angles created between the Camper’s, Palatal, and Occlusal planes with SN were measured to give SN-Camper’s (C),SN-Palatal (P), and SN-Occlusal (O) respectively. Results and conclusion:  Camper’s plane closely imitates the occlusal plane of fully dentate subjects with skeletal Class I maxillo-mandibular relationship therefore it may be a better guide to re-establish the occlusal plane and  Middle border of the tragus with inferior border of the ala of the nose can be most accurate in locating artificial occlusal plane
