Digital smile design (DSD): influência na percepção e preferência do paciente e do cirurgião-dentista quanto a estética do sorriso no Mock up

Abstract

Aesthetic perception is a highly subjective concept and the opinion of professionals regarding smile aesthetic evaluation may not meet the perception and expectation of patients and lay people. Tools such as the Digital Smile Design (DSD) allows reproducing to the patient in a more comprehensive way, what was planned by the professional, still in the phases that anticipates the execution of the restorative treatment, such as diagnostic the wax-up and mock-up. However, the result obtained by the DSD may not meet the patient’s expectations, besides being a stage that demands time and training. This work aimed to evaluate whether the use of the DSD influences the making of the diagnostic wax up and the perception and preference of the patient and the dentist on the aesthetics of the smile with mock ups obtained from waxes with and without DSD. The sample consisted of 10 patients recruited from individuals who had interest and need for aesthetic smile treatment and 10 dentists who use the DSD on a regular basis. Initially, two wax-up were performed for each patient, one performed in the traditional way, without the DSD, and another guided by the DSD. Two mock-ups were performed, one for each wax-up. After installation, the following photographs were taken with the mock-up: 1. frontal facial at rest, 2. frontal facial at maximum smile, 3. frontal lip approximation at rest, 4. frontal lip approximation at maximum smile, 5. frontal lip approximation with retractor . The photos were presented to the patients individually, along with a Preference Sheet, where they assigned the alternative regarding the smile that most pleased them: 1. photo without intervention; 2. mock-up photo with DSD; 3. mock-up photo without DSD; 4. none of the above; 5. indifferent. The patients opted on their own photos and the dentists evaluated the photos of each one of the 10 patients. It has been observed that there is a tendency by the patients and dentists to prefer the mock-up without DSD, possibly because it is closer to the natural morphology of the teeth.
