[Gingival and dental parameters in the evaluation of aesthetic characteristics of fixed restoratons (II)]

This paper is a continuing evaluation of dental and facial parameters in the estimation of aesthetic characteristic of fixed restorations. First of all, attention is paid to the phenomenon describing the tooth tissue's characteristics (translucency, opalescence, and transparency). The paper also discusses tooth colour as a special occurrence, the position of the lower lip line as well as the symmetry of the smile. In addition to these fundamental objective criteria, the paper also deals with subjective criteria (tooth arrangement and position, variation in tooth form, and relative crown length), which play a part in the successful aesthetic integration of fixed restorations.
