The edges of the maxillary incisors should look like a circular line from the front to the back when you smile. This line, called the “spee curve” in dentistry, makes the smile quite aesthetic.
For an aesthetic smile, posterior teeth are expected to appear at a certain level on the smile line. If not, dark areas at the corners of your mouth may cause an unpleasant appearance.
In an ideal smile the imaginary line that passes through the pupils is parallel to the line tangent to the the edges of the two central incisors.
Symmetry is very important because the mismatch in the shape and dimensions of the incisors is easily spotted. In this respect, the providing a symmetrical view as far as facial lines allow adds an extra charm to the smile.
The embrasures are natural spaces between the edges of the teeth. For an aesthetic and ideal smile, the sizes of embrasures must increase from incisors to posterior teeth.
The width and height of the upper incisors in the visible area of the mouth must be 1/16 of the width and length of the face. For an aesthetic smile, the size of the teeth must suit to this rule. For example, the ratio between the width of anterior incisors and the width of lateral incisors should confirm the golden ratio.
To have an aesthetic smile, the ratio between the width and the height of the two central incisors must match the golden ratio.
Your teeth have never only one color. The natural color of a tooth is neither pure white, nor a single color. The colors of dentin and enamel are always different. There is also a color difference between the cutter tip of the tooth and the bottom part that is close to the gum. Besides, one of the important factors that make up the color of the teeth is light reflection and light absorption. The light transmission of the cutter tip of the tooth and the bottom part that is close to the gum is not equal. So the color and the transparency change according to the part of the tooth.
A tooth has three parts: 1- the bottom part that is close to the gum: this part is yellowish and opaque even for the brightest and whitest smiles; its light transmission is low. 2- the middle part of the tooth: less yellowish and % 25 transparent; its light transmission is more compared to the bottom part. 3- the cutter tip of the tooth: usually % 50 transparent and whiter than the other parts; but as it has more light transmission, it looks grayish under bright light, because the darkness of the mouth is reflected through its transparency.
The complexity of the differences in color and transparency of natural tooth shows us that we have to approach this issue with great attention in cosmetic dentistry. It is very important to be able to match the natural tooth color of the patient when making all-ceramic aesthetic crowns. In order to be able to this, we have to get a detailed color and transparency analysis and to project a color map of the teeth.
The curve of the lower lip must be equal to the curve joining the edges of the anterior incisors. As much as these curves match each other, the patient will have a younger and more attractive smile.
Gingival line, that appears when you smile, must be parallel to the line of the upper lip. Gingival line is like a frame circling a beautiful Picture and adds meaning to your smile.
AESTHETIC TEETH TREATMENT
When it comes to dental aesthetics, it is not enough to choose only among options such as laminate, zirconium coating, e-max, onlay or whitening. Since the morphological, technical and aesthetic details of the existing teeth such as morphological structures, colors, forms, transparency and natural effects directly affect the natural and aesthetic appearance of the teeth, the process should be started after evaluation.
One of the factors that increase the success in aesthetic treatments is the good communication between patient and the dentis and if the patient is expressing his/her expectations concretely and clearly. Explain your expectations to the professional concretely, use photographs if possible. The biggest problem in aesthetic treatments is the insufficient communication between the denitst and the patient. You can contact our patient care coordinators who are well informed about aesthetic treatments and get detailed and realistic information about the processes.
