Evaluation of “Golden Proportion” in Individuals with an Esthetic Smile

One of the most important tasks in esthetic dentistry is creating harmonious proportions between the widths of maxillary anterior teeth when restoring or replacing these teeth. The "golden proportion" is a main guideline introduced in this field. This study aimed to investigate the existence of the golden proportion between the widths of the maxillary anterior teeth in individuals with an esthetic smile. This study was conducted with 157 dental students (75 women and 82 men), with ages ranging from 18 to 30 years. Students whose natural smile did not develop any visual tension with regard to the study's and their own criteria were selected as having esthetic smile. An image measurement program was used to measure the apparent mesiodistal widths of six maxillary anterior teeth on the scanned photographs of these subjects. The existence of the golden proportion was investigated in the width ratios of maxillary anterior teeth. The golden proportion was not found to exist between perceived maxillary anterior teeth widths of individuals with an esthetic smile. The golden proportion is not a common factor in esthetic smiles. This article suggests considering the dentofacial specificities of each individual and also the wide variety of natural teeth proportions when restoring or replacing the maxillary anterior teeth. However, individual cultural characteristics and perception of beauty must be considered.

The relationship between intercanthal dimension and the widths of maxillary anterior teeth

Statement of Problem. One of the difficult aspects of complete denture prosthodontics is the selection of appropriately sized maxillary anterior teeth. Many attempts have been made to establish methods of estimating the combined width of maxillary anterior teeth and/or central incisors. Purpose. The aim of this investigation was to determine whether a relationship exists between the intercanthal dimension and 4 mesiodistal width combinations of the maxillary anterior teeth. Material and Methods. The maxillary anterior teeth of 443 adult subjects were examined. Intercanthal distance was measured between the median angles of the palpebral fissure. The mean widths of the 2 central incisors, the combined widths of the central incisors, the combined width of the 4 incisors, and the combined width of the 6 anterior teeth were determined intraorally at their widest dimension. Pearson correlation coefficients were calculated to determine the relationship between intercanthal distance and the 4 measurements of maxillary anterior teeth (α=.05). Results. Although the Pearson correlation coefficients were relatively small, a significant relationship existed between intercanthal dimension and the 4 maxillary teeth dimensions (P<.0001). It was found that biometric ratios of 1:0.267 and 1:1.426 could be used to estimate the central incisor width and the combined widths of the 6 anterior teeth, respectively. Conclusion. Within the limitations of this study, the results suggest that intercanthal distance can be used as a preliminary method for determining the width of the maxillary anterior teeth for edentulous patients.

Determination of approximate size of maxillary anterior denture teeth when mandibular anterior teeth are present. Part II: Mold selection

Consequently, when mandibular anterior teeth are present, the arch width from distal-of-canine to distalof-canine can be measured, and this measurement times 1.3 equals the required arch width of maxillary anterior teeth to produce a Class I canine relationship. To allow for intentional disclusion of the maxillary anterior teeth arrangement, the ratio can be slightly modified. A ratio of 1.38 will usually yield the desired result. There is an acceptable range of minimum and maximum for the mesiodistal width of the selected maxillary anterior teeth mold.
