Assessment of Patient Satisfaction and Treatment Outcomes in Digital Smile Design vs. Conventional Smile Design: A...

The esthetics of a smile holds significant importance in an individual's self-esteem and overall quality of life. In the realm of cosmetic dentistry, smile design has traditionally relied on conventional methods, but recent advances in technology have introduced digital smile design (DSD) as a promising alternative.

In this randomized controlled trial, 150 adult patients seeking smile enhancement procedures were enrolled and randomly assigned to one of two groups: the DSD group or the conventional smile design group. The DSD group underwent smile design using digital technology, including intraoral scans, computer-aided design, and 3D simulations. Meanwhile, the conventional smile design group received smile design through traditional methods, involving manual impressions, stone models, and manual wax-ups. Patient satisfaction was measured using a visual analog scale (VAS) ranging from 0 to 100 immediately after the procedure, while treatment outcomes were assessed three months post-procedure by dental professionals using a standardized assessment scale.

In terms of patient satisfaction, the DSD group demonstrated a mean score of 85.4 (SD ± 6.2), while the conventional smile design group had a mean score of 79.8 (SD ± 7.1). This suggests that patients in the DSD group reported higher levels of satisfaction with their smile enhancements. Regarding treatment outcomes, 92% of patients in the DSD group exhibited excellent restoration fit, occlusion, and esthetics, whereas 78% of patients in the conventional smile design group achieved the same level of excellence. These findings collectively indicate that digital smile design (DSD) may yield superior patient satisfaction and improved treatment outcomes when compared to conventional smile design methods, particularly with regard to esthetic results and overall patient contentment.

In conclusion, the results of this randomized controlled trial emphasize the potential advantages of integrating digital technology into smile design procedures.
