Abstract: Objective: The purpose of this study was to establish Tweed?s cephalometric norms for Maratha ethnic population and to compare it with Caucasian norms. Materials and Methods: The participants were of 66 adults with normal occlusion and pleasant profile. Lateral cephalograms were taken in natural head position, and cephalometric norms were established using Tweeds diagnostic triangle. Results: The result of the study also indicated that larger IMPA of 101.63? instead of 86.93? and smaller FMIA of 52.66? in Maratha participants as compared to 68.20? in Caucasians indicated proclined mandibular incisors in Maratha population than the Caucasian norms developed by Tweed. Conclusion: The findings emphasize the need for group specific norms for orthodontic diagnosis and treatment planning and provide cephalometric standards for normal Maratha adults.
