What is considered beautiful is based on standard aesthetic principles about balance and symmetry between teeth, eyes and the rest of the face. In order to design the ideal smile, we follow some important principles to ensure we give you the best aesthetic smile.
1. Smile Line
The first aspect of a patient’s smile that we look at is the smile line. It is essentially the smile pattern. While there are as many different smiles as there are people, they can generally be categorized as one of three basic smile patterns: the Commissure smile, the Cuspid smile, or the Complex smile.
The Smile line which connects the edges of your teeth should ideally follow the curve of your lower lip and is generally radially parallel to the horizon. The teeth bite-line shall follow the curve of the under-lip. The upper teeth have a shape of a “gull.” A curved smile line makes you smile younger but to flat smile line, the teeth will have more a worn-out look and makes you older.
2. Relative Dental Proportion
Three measurements must be symmetrical with regard to the top 6 teeth, known as the “social six”. Combined width of 2 front teeth should be same length from midpoint to either 3rd tooth cuspid. Front 2 teeth should have combined width to height ratio, Golden in proportions, being 1 in height and 1.6 in width. The golden section is the geometrical proportions that exist everywhere around us. A beautiful smile has the proportions close to the golden section between teeth: 0.6 – 1.0 – 1.6
3. Dominance of the Central Incisors
Under this principle we look at the width to height proportions of the maxillary central incisors. Ideally, the width should be 75% to 80% of the height of the individual teeth. We also judge how symmetrical they are, and whether the mid-line runs perpendicular. Finally, we look at whether the incisal edges run parallel to the inter- pupillary and the incisal display.
4. Smile Width – Silhouettes
In looking at a patient’s silhouettes we look to see that the teeth have a consistent curve as they progress into the back of the mouth. Specifically, we look at three measurements:
- Anterior – distal of central to distal of lateral
- Posterior – cuspid to premolars and molars
- Decreasing gradation
In the case of a narrow smile your front teeth will appear to stand alone as the side teeth are in the shadows.
5. Progression of Incisal Embrasures
After analyzing a patient’s silhouettes, we look at the progression of their incisal embrasures. As one of the elements that can make or break a smile, this progression should ideally be a gradual one. Emrasures are the natural little triangular spaces that you see between the tips of your teeth. We create artistic natural embrasures to give you your dream smile.
