In recent years, dentistry has made great advances in dental esthetic techniques, with the aim of providing each patient with the necessary treatments to achieve a perfect smile according to their needs and characteristics. Smile design is the ideal treatment to achieve a completely healthy and natural-looking smile, adapted to the physiognomy of each patient.
Smile design, the technique to show off a cinematic smile
The Den Clínica Dental smile design procedure requires an exhaustive review and a complete diagnosis, in order to identify all the needs of the patient’s mouth and achieve the most appropriate treatment in each case. Using specific design software and following aesthetic criteria, the dental team is able to adapt the perfect smile to each patient so that it looks natural and harmonious.
To achieve this natural effect, the position of the teeth is studied, as well as their harmony with the gums and lips. Also the physical characteristics of the patient beyond the mouth, such as physiognomy, skin color, sex, age and preferences of the patient. The objective is to achieve the best smile.
How is the smile designed?
This dental esthetic procedure requires a previous study of the patient’s characteristics. This analysis is divided into three areas:
1. Vertical analysis.
In this analysis two aspects are taken into account: the proportions and dimensions of the teeth; and their relationship with the surrounding components. For a smile to look harmonious and natural, the teeth must keep strict proportions of height, width and size between them.
The position of the upper incisors should allow 2 to 4 mm to be visible with the lips at rest. When smiling, the lips should rise higher from the corners of the mouth than in the center of the mouth, which creates a curved line with upper concavity. For the smile to be completely harmonious, the edges of the upper teeth should be aligned in such a way that they describe a curve with the same upper concavity that the lips form.
In addition, the teeth should also be level with the gums, specifically with the gum line. As the upper teeth have different sizes, it is important to maintain symmetry on both sides of the smile, and that they maintain a curved line with upper concavity.
Only when the concavities and lines of teeth, lips and gums coincide, a proper smile is produced.
2. Sagittal analysis
The sagittal analysis consists of the analysis of the profile. To analyze the patient’s profile, a vertical line passing through the so-called subnasal point, which is the midpoint of the lower edge of the nostrils in profile, is used. Using this point as a reference, the upper lip should extend beyond this imaginary line by 2 to 4 mm, the lower lip should remain 2 mm behind the upper lip, and the chin should be 2 to 4 mm behind the lower lip.
The upper incisors are the support for the upper and lower lips, with a key position for dental esthetics, so they should be positioned to give this support optimally.
3. Masticatory analysis
In this analysis, the patient’s masticatory function is evaluated, since for the design of the smile to be effective, the masticatory function must be perfect.
By means of images of the interior of the oral cavity, we can observe that the functioning of the masticatory function does not overload any of the components of the masticatory system and guarantees the health of the dental pieces.
An esthetic and efficient smile
From all these records, a diagnosis is made and a treatment plan is proposed accordingly. In this diagnosis, a series of treatments are proposed, following some fundamental criteria that govern the relationship between functionality and dental and gum esthetics. Some of these treatments can be: the implantation of veneers, cold light whitening, the reconstruction of tooth edges, gum surgery, the change of fillings to other more aesthetic white fillings or the implantation of dental pieces among others.
By means of the smile design software, a 3D digital image of the patient’s smile is obtained. The program’s virtual simulations allow the dentist to choose the most appropriate smile for each patient and the patient can see the result before the treatment is performed, so that he or she will go to the dentist with greater confidence and motivation.
