Multidisciplinary design: Creating a common perspective in complex cases.

OBJECTIVE: This clinical report describes and illustrates digital treatment planning and interdisciplinary orthodontic, surgical, and prosthetic treatment in a highly complex clinical case. CLINICAL CONSIDERATIONS: Analogue design protocols through wax ups are highly variable, technique sensitive, and operator dependent. Digital smile design and treatment planning tools facilitate simplified processes through the use of natural tooth libraries, based on the specific esthetic and functional needs of the individual patient. The vast information compiled in the virtual patient and the treatment plan consolidated in the initial digital design facilitate true interdisciplinary treatment planning and execution, with all dental specialties involved, from orthodontic to surgical and prosthetic treatment. CONCLUSIONS: Digital protocols and design tools provide clear clinical roadmaps for increased efficiency, precision, and predictability, vastly improving the quality of interdisciplinary patient care. CLINICAL SIGNIFICANCE: While analogue protocols are technique sensitive and largely dependent on the operator, digital smile design, and treatment planning tools offer opportunities for truly patient-centered individualized care and interdisciplinary treatment.

Perceptions in Digital Smile Design: Assessing Laypeople and Dental Professionals' Preferences Using an Artificial-Intelligence-Based Application.

Digital Smile Design (DSD) is used in many fields of dentistry. This prospective observational study assessed laypeople's and dental professionals' perceptions of a DSD application. SmileCloud, an online DSD platform, was used to create two different designs for three patients; after that, the participants, in a 30-question online illustrated survey, were asked about the most attractive design and other features of the smile. Dentists' and laypeople's perceptions about specific DSD features were assessed. The Kolmogorov-Smirnov normality test was used. Descriptive and crosstab analyses compared the respondents' opinions for each statement. Chi-square tests were used to determine the relationship between the questions and any association with age, gender, and profession. The test results were rated as significant at a p-value < 0.05. A total of 520 participants (dental professionals, students, dental technicians, and laypeople) were enrolled. The statistically significant features were self-esteem related to appearance (p = 0.05), facial and smile symmetry (p = 0.42, p < 0.0001), tooth color (p = 0.012), and symmetry of gums (p < 0.001). For each patient, the design with dominant round upper incisors and perfect symmetry was preferred (p < 0.001). Digital pre-visualization benefits diagnosis and enriches treatment planning. The dentist-dental technician-patient team should be involved in the decision-making process of pre-visualization.
