ABSTRACT
The aim of the study. To compare the efficacy of digital technologies (photographic documentation, planning in Adobe Photoshop, digital shade matching, creation of a silicone guide based on a digital wax-up) and the conventional technique for direct composite restorations of anterior teeth.
Objects and methods. The study involved a 20-year-old patient with enamel fractures of teeth 1.1 and 1.2. The restoration of tooth 1.1 was performed using a digital protocol: planning in Photoshop, shade selection using the HSB model, and the creation of a digital wax-up and a silicone guide. Tooth 1.2 was restored using the conventional method with visual shade matching and incremental composite layering. The outcomes were evaluated according to the FDI criteria and a subjective VAS scale.
Results and discussion. The FDI evaluation showed a significant superiority of the digital restoration (tooth 1.1) in aesthetic parameters (color, translucency, shape). The functional characteristics of both methods were comparable. Subjective evaluation (VAS) identified digital shade matching as the most valuable step, despite being time-consuming. Digital planning and the silicone guide proved highly effective for recreating tooth anatomy but were noted as less accessible. Digital technologies ensured a predictable aesthetic outcome, despite requiring additional resources.
Conclusion.  Digital methods significantly outperform conventional techniques in terms of the aesthetic outcomes of restorations. Their use, despite requiring additional resources and training, is justified by high precision and predictability, making them a promising approach for integration into clinical practice.

Keywords: digital technology, color models, composite restoration, silicone matrix, VAS subjective assessment scale
