In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. The figure on the right illustrates the geometric relationship.
The Golden Ratio (also known as the Golden Section, Golden Mean, Divine Proportion or Greek letter Phi) exists when a line is divided into two parts and the longer part (a) divided by the smaller part (b) is equal to the sum of (a) + (b) divided by (a), which both equal 1.618.
The Golden Spiral can be used as a guide to determine the placement of content. Our eye is naturally drawn to the center of the spiral, which is where it will look for details, so focus your design on the center of the spiral and place areas of visual interest within the spiral.
You’ll find this beautiful creature throughout nature’s forms—ferns, flowers, seashells, even hurricanes—which perhaps why we find it so visually appealing. Because it is, indeed, nature at its finest.
Tooth to Tooth Relationships
The first Golden Proportion relationship, and the most important to be discovered, is a simple tooth to tooth Golden Proportion as shown above. This shows the Golden Mean Gauge superimposed on a photograph of teeth showing that the width of the central incisor is in the Golden Proportion to the width of the lateral incisor. Similarly, the Gauge shows the lateral incisor is in the same Golden Proportion to the canine in the adjacent photo and the canine is in the Golden Proportion to the first premolar.
The four front teeth, from central incisor to premolar are the most significant part of the smile and they are in the Golden Proportion to each other. This phenomenon has been combined in a grid which can be used to assist us in perfecting the aesthetics of the eight front teeth. The adjacent diagram shows such a grid in the mouth with the front teeth clearly shown in the demarcations predicted.
Note also that the grid lines up with the corner of the mouth (i.e. the end of the smile) and the dominant corner of the arch, predicting both positions.
The widths of the spaces for the teeth are all in the Golden Proportion to each other.
The number in the solid circle refers to the width of the central incisor. There are 7 grids to accept all widths of central incisor from 7 to 10 mms in steps of 1/2 mms. The grid also shows a number in a dotted circle which refers to the width of the smile.
