'Do the math" - The influence of tooth color on preparation design for porcelain veneers from a minimally invasive perspective
Various types of tooth preparations for porcelain veneers have been proposed, depending on factors such as the properties of the ceramic material, remaining tooth color, need for altering the tooth contour, laboratory fabrication technique, and occlusal relationships. Clinical observations of successes and failures associated with the development of techniques and materials have allowed some safe parameters to be delineated for effectively performing dental preparations for porcelain veneers or even bonding veneers without any preparation.
- To describe the parameters that must be taken into consideration before the dentist take the handpiece and start this irreversible procedure
- To avoid excessive or incorrect tooth preparation by indicating the exact amount and location of the tooth reduction necessary to attain the desired color and shape.
