Analysis of Golden percentage on Maxillary Anterior Teeth for Estethic Smile Design

Introduction The teeth in front are an important segment in the aesthetics of an individual, but the maxillary central incisors are the dominant element, they need to have appropriate proportions in terms of height and width in order to have the best possible aesthetic results. Aim The aim of this study is through digital photographs and computer analysis, to determine the Golden percentage according to Snow where the individual width of the front tooth is calculated as a percentage of the total width of the front six teeth, and for canines is 10%, for lateral incisions it is 15%, and for central incisions it is 25% of the total distance measured in the frontal segment, in patients with natural teeth. Material and Methods Frontal photographs were taken of patients with a posed smile, using a digital camera (NIKON) under standardized conditions, 1 meter away from the patient's, and the lens was aimed at the patient's lips. A digital computer program was used to process the photos and take the measurements. A total number of patiens is 15 respondents, aged between 18 to 30, of which 6 are men and 9 are women. An equal number of patients are included in the Angle classification. Results After the conducted analyzes and the summarized results regarding the gender classification, we obtained the following percentage representation in the male population is 12.49%, 14.83% and 21.95%, while in the female population it is 12.93%, 15.16% and 21.9%. Regarding the Angle classification in patients with Class I, we obtained the following percentage of 12.12%, 15.18%, 22.57%, in Class II 14%, 15.14% and 21.39%, while in Class III it is 13.74%, 14.72% and 21.45% . Conclusion According to the obtained results, the percentage of lateral incisions is the only one that is close to the golden percentage, while all other obtained results do not match.
