Abstract :

Background: Edentulism whether partial or total has a profound impact on life of individual in terms of social well being and general health of the individual. As teeth form an integral part of facial esthetics, their placement should be compatible with facial features and at the same time should be functional and esthetically pleasing. To fulfill the patient esthetic criteria and to give the patient a pleasing smile, selection of anterior teeth is very important. Aims and objectives: To determine the relationship of tooth form, arch form with the face form. Materials and methods: A total of 500 subjects of age group 18 to 25 years were selected for the present study. Impressions of the maxillary arch were made and models were generated. Standardized photographic procedure was used to record the patients face and central incisor form. Similarly photographic procedures were used to capture the arch form from the model and these images were transferred to a computer and were superimposed using an Auto – cad software to evaluate the correlation among each. The results were tabulated and SPSS –20.0 was used for statistical analysis. The statistical test used were Mean, Standard deviation (SD), p–value, and chi square test. Results: The results obtained showed that, the arch form to face form showed more similarity of 36% when compared to the face form with tooth form with similarity of 32%. Conclusion: As per the results obtained, it can be concluded that the face form cannot be taken as sole guideline in selecting the artificial teeth.
