Aesthetic criteria in smile design include many factors such as facial features of the person, the structure of the teeth and the holistic harmony of the smile. In addition to making the smile look aesthetically pleasing, these criteria also improve dental health. The main aesthetic criteria considered in smile design:
1. Shape and Size of Teeth
• The length, width and general shape of the teeth directly affect the aesthetic harmony of the smile. Teeth should be compatible with the person's facial structure, lip shape and the appearance of the gums. For example, long teeth can give a young and energetic appearance, while short teeth can create an older impression.
2. Arrangement and Symmetry of Teeth
• Arranging the teeth in a neat and symmetrical way is of great importance in terms of aesthetics. Asymmetrical or entimed teeth can upset the balance of the smile. Therefore, the alignment of the teeth with orthodontic treatments is an essential part of the smile design.
3. Gum Line (Gingival Aesthetic)
• Gum health and appearance is an important part of aesthetic smile design. The gum line should be smooth and proportional to the teeth. Problems such as gum recession, visible gummy smile are corrected with laser or surgical interventions.
4. Color of Teeth
• The whiteness and shiny of the teeth is an essential element in smile aesthetics. It is aimed that the teeth have a natural-looking whiteness; therefore, procedures such as tooth whitening and porcelain lamina are frequently applied. The color of the teeth should be chosen to suit the skin color and lip structure of the person.
5. Golden Proportion
• The golden ratio principle in aesthetic dentistry states that the teeth should be in ideal proportions with each other and facial lines. When a certain harmony between the dimensions and shapes of the teeth is achieved, a natural and aesthetic smile is obtained.
6. Compatibility of Lips and Teeth
• The relationship of lips with teeth is of great importance in smile design. The distance between the upper lip and lower teeth during a smile directly affects the aesthetic appearance of the smile. In the smile design, the relationship of the lips with the teeth is examined to provide optimal harmony.
7. Harmony with Face Shape
• The face shape of each individual is different and the teeth should be designed in accordance with this facial structure. Different tooth forms are selected for oval, round, square or heart-shaped facial lines. Teeth that match the face make the smile aesthetically perfect.
8. Smile Line
• Arranging the upper teeth parallel to the lower lip while smiling is called a "smile line". An ideal smile line ensures that the teeth are aligned and in harmony with the lower lip.
These aesthetic criteria help to achieve a result suitable for both the aesthetic and functional needs of the person by offering personalized solutions in smile design. According to the facial structure and expectations of each individual, these criteria are evaluated by the dentist and a personalized plan is created.
