The recent development of aesthetic dentistry reflects a concentration of the dentists’ concern for satisfying patients’ requests for an aesthetic appearance of their teeth. Modern dentistry combines medical treatment with the art of aesthetic restorations. Over the years, the restoration of the facial harmony has changed its character, from random to necessary, and from optional to compulsory, as the aesthetic defects have become less and less accepted. Aim: Contributions to understanding the principles that must be respected in dental-facial aesthetics and their application in various accessible prosthetic techniques that lead to significant improvement of the aesthetic appearance of the final restoration. Material and methods: The study included 22 (aged 40 to 80 years) patients (mean age: 60 years), presenting to the Department of Clinical Dentistry for different types of prosthetic restorations. Results and discussions: Taking into consideration the aesthetic principles and criteria, the prosthetic restorations in two similar clinical situations were performed using a different methodology. Conclusions: To grant the actual interventions the necessary provisions of true clinical success, the dentist must have and develop the skills that allow him/her to be valued as both a scientist, and an artist.
