Dental aesthetics has always been an integral part of practical dentistry despite the fact that only in the last decade it has benefited from an objective critical analysis. Initially, aesthetics is regarded as an art - synonym for subjective, romantic and sentimental sensations. At a time when the basic aesthetic principles were based on Greek and Roman mathematics, the painters studied the aesthetics in order to create the painting, reflected in the depths of our soul. One can have an everlasting discussion about the two facets of dental-scientific and subjective aesthetics. It can be difficult to differentiate dental aesthetics from distinct units because all components are closely interrelated and interdependent. Complete and complex oro-dental treatments should be performed in such a way as to give back the patient both the masticatory functional skills, the feeling of comfort and the aesthetically lost aspect. The general trend in dental medicine focuses on replacing materials that, while meetingfunctional requirements, are not aesthetically pleasing. Thus, new generations of composite materials or integral ceramics take precedence over metal alloys used in dental treatments, from amalgam alloys to metal prosthetic restorations, including even gold ones. The database includes selection, examination and prosthetic resolution of 38 cases in the University of Galati University Prosthetic Clinic in the period 2016-2018. The possibility of creating unidirectional prostheses is a plus in the realization of true to nature works. Prosthetic variants, like dental faces, through which changes in shape, colour and even slight position can be made, with minimal invasiveness, or even non-invasive in the case of no-prep facets are a real advantage to aesthetics. From a biological point of view, the IPS e.max Press ceramic whole system is superior in that it is chemically inert, has a dental-like hardness, therefore it does not produce abrasion, the lack of metal avoids gingival changes colour, galvanic phenomena, and also a possibility of treatment for allergic persons in different components of the metal structure; the biocompatibility of these materials is clearly superior.
