The Influence of Tooth Color on Preparation Design for Laminate Veneers from a Minimally Invasive Perspective: Case Report
Coachman, Christian / Gurel, Galip / Calamita, Marcelo / Morimoto, Susana / Paolucci, Braulio / Sesma, Newton
Various types of dental preparations for laminate veneers have been proposed, depending on factors such as the properties of the ceramic material, remaining dental structure color, need for altering the dental 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 ceramic veneers or even placing veneers without any preparation. This article describes the use of an additive diagnostic wax-up that is transferred to the mouth by means of an intraoral mock-up (aesthetic pre-evaluative temporary) with associated mathematic parameters to guide dental preparations. This technique, called Do the Math and presented here in the form of a clinical case report, aims 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.
