Abstract
Orientation of occlusal plane for complete dentures play a vital role as it affects all the basic requirements of complete dentures. Depending on soft tissue landmarks for orienting occlusal plane seems to be unreliable. Cephalometrics were introduced in Prosthodontics to orient the occlusal plane in the same position as it was with the lost natural teeth.
 In the present study, 60 lateral cephalometric radiographs of a group of male and female dentulous subjects of Indian and Nepali origin (30 subjects in each group) were obtained and tracings were made. All the subjects selected were in the age group of 20-30 years in whom the facial growth was completed. Angular measurements were made between FH (Frankfort Horizontal plane)- CP (Camper's Plane), FH-OP (Occlusal Plane) and CP-OP and subjected to statistical analysis to determine the degree of separation between these planes in Indian and Nepalese ethnic groups.
 The absolute parallelism between the natural occlusal plane and Camper's plane were not proven in both Indian and Nepalese subjects involved in this study. This significantly reduces the reference values of these planes in Prosthodontics.

Summary
Complete dentures mainly restore the function of mastication along with esthetics and other functions. Various factors that affect the stability of complete denture are: the proper location and arrangement of the artificial teeth, the size and form of the basal seat, the quality of the final impressions and so on. Amongst these factors the orientation or inclination of plane of occlusion is under operators control. Establishment of the optimum level and inclination of the occlusal plane poses a dilemma in an edentulous mouth in the absence of definite guidelines. Optimum level and inclination of the occlusal plane play important role in biomechanics of craniomaxillary morphology. The reconstruction of the natural level of the occlusal plane in the edentulous mouth enables the normal function of cheek and tongue muscles and other surrounding structures.[1, 2, 3, 4]
