The novelty of this approach, as with the “Facial Keys” articles, is an emphasis on soft tissue facial measurement. This article describes various soft tissue traits that contribute to an aesthetically pleasing face which should be considered during orthodontic treatment. The aim of the present study was to propose soft tissue norms for Himachali population. Materials and Methods: Lateral cephalograms of 100 Himachali subjects (50 males and 50 females) of age group 18-25 years were taken in Department of Orthodontics, Himachal Institute of Dental Sciences, Paonta Sahib and tracing of soft tissue profile as well as related osseous and dental structures were made using Nemoceph software. Then Arnett’s soft tissue traits were studied as described by Bergman. Results: The present study showed that, a horizontal growth tendency in Himachali is acceptable esthetically. A fuller upper lip is considered balanced and esthetic. Increase in lip incompetency is considered unaesthetic. Conclusion: An increased posterior height resulting in horizontal growth tendency is acceptable esthetically. Individual norms are necessary for a population in order to plan and deliver quality treatment.

Introduction Preservation of facial attractiveness is a primary goal of orthodontic treatment. Treatment planning requires knowledge of the parameters and normative data that helps to establish goals and predict the obstacles that need to be negotiated. Due to a complicated interaction of genetic and environmental factors the morphological features of an individual vary from race to race. Even within the same race, each subgroup had its own standards. Hence, the established norms for other ethnic group can not apply to the population of Himachal Pradesh. Therefore, the applicability of various soft tissue parameters proposed by Bergman, should be analyzed which will improve treatment planning for population of Himachal Pradesh. [1] As Soft tissue norms serve as a guideline in calculating change it has been suggested that certain cephalometric standards relating teeth to cranial or facial bones could ensure good facial form if adhered to as a treatment goal. [2] The attainment of facial soft-tissue proportionality is one of the principal goals in the treatment of dentofacial deformities and can be achieved with properly planned and executed orthognathic surgery techniques. [3] Therefore the aim of this study is to calculate the norms for the population of Himachal Pradesh so that the soft tissue cephalometric values of various parameters could be differentiated from that of other populations so as to guide the
