A Study on the Practical Applicability of the Rule of Golden Rectangle in Dental Aesthetics


Abstract - Maxillary central incisors are of critical value in the aesthetics of a smile. The Golden Rectangle ratio concept may play an important role in selecting the optimum width and length of this tooth. The aim of the study was to investigate the existence of this ratio among individuals with natural dentition and to validate its role in aesthetic oral rehabilitation. The clinical crown length of the maxillary left central incisor (CI) and combined crown width of the maxillary left and right CI of 70 subjects were measured. The crown width to crown length ratio was calculated and compared with the Golden Rectangle ratio and statistically analysed. Eighty percent of the subjects varied within 2 standard deviations of the ratio of 1.618. No statistically significant influence of gender on the ratio was observed. Golden rectangle was found to have a significant relationship with aesthetic appearance of maxillary central incisors.

KEY WORDS: Golden Rectangle, aesthetic ratio, maxillary central incisors.
