Aesthetic Parameters of Lower Anterior Teeth

摘要

The training in aesthetic parameters has been, for the most part, confined to the upper arch, yet there are studies which show that as age increases, more is seen of the lower anterior teeth. To design a lower anterior fixed prosthesis for good aesthetics, this paper determined that the following factors should be considered: degree of vertical and horizontal overlap; curve and height of the teeth; anterior placement of the incisal edge; and incisal contacts. Design factors which must be manipulated by the dentist is his prescription and techniques in fabrication are: overlap; incisal wear and facetting; and height and variety of contact area. (Author)
