Shade management using a new zirconia-reinforced lithium disilicate press ceramic system and leucite-reinforced glass-ceramic veneering system

The adhesive bonding technique together with tooth-colored ceramic material in fabricating veneers is considered one of the greatest achievements in modern prosthodontics. There is a wide range of indications for veneers, but they are most commonly used to establish adequate function and mask tooth discolorations and inappropriate tooth shape, size or position. A large variety of all-ceramic materials with excellent properties is available on the market today. It is challenging to select the material that will provide the best esthetics and function. The present article explains the principles of a modern, individual treatment approach for a young adult patient with multiple diastemata and shade disharmonies in the maxillary anterior teeth. The treatment plan was based on the selection of the appropriate ceramic material and technical procedures to achieve the best esthetic results using veneers. This included analyzing the specific case; defining the treatment goal; determining the precise shade; and selecting the most suitable and appropriate ceramic material, preparation design, fabrication technique, and adhesive concept. It was decided to use the new VITA zirconia-reinforced lithium disilicate press ceramic system and leucite-reinforced glass-ceramic veneering system to fabricate indirect ceramic veneers for all the maxillary anterior teeth. The size, shape, position, and shade of the natural teeth were changed and the diastemata were closed to achieve a more proportional dental relationship. The esthetic and functional goals were achieved and the patient was extremely satisfied with the final outcome.
