Smile design, which is evaluated under the scope of aesthetic dentistry, provides the reconstruction of teeth and gums that spoil the aesthetic appearance for various reasons. Smile design, which helps the patient to have a beautiful and natural appearance as much as possible, is realised by applying many procedures together. While designing the smile, the patient’s expectations, age, gender and facial features are taken into consideration. Before smile design, if there are gum diseases or decayed teeth, these problems should be treated. After tooth cleaning procedures are applied, procedures are determined according to the patient’s needs. These procedures are usually prosthesis applications, implants, teeth whitening, gum aesthetic interventions. It is very important to understand the aesthetic expectations of the patient correctly and to determine their needs correctly in smile design. A preview can be made after the plans made on the models prepared with the measurements taken from the patient’s mouth. With the approval of the patient, the procedures are completed within the scope of the smile design planning drawn for the patient.
