The present article deals with the rendering of perspective, which is the science and art of representing three-dimensional objects on a flat surface. The clinical rendering of perspective is connected to the clinician’s ability in reconstructing the three dimensional aspects of prosthetic restorations. The basic principles which have to be followed are described in this article. These are the principles of size and form, the principles of partial coverage and texture details, and the principles of shadow and lightness management.
All necessary information for clinical application is provided, as well as some special morphological elements which are significant for the achievement of perspective. In addition, some manipulations of the overlapping, twisting, inclination of the teeth are described, which promote the rendering of perspective in a given dental composition.
Regarding the correlation between colour and perspective, some of the basic principles relating to the reflectivity of the surfaces of the teeth are also presented. According to the fundamental principles for aesthetic restoration, some information about the properties and the management of aesthetic restorative materials are mentioned.
Finally, a discussion is presented leading to conclusions including useful suggestions for clinicians in everyday practice.
