User Report F oundedin1924,VITAZahnfabrik’s priority has always been to meet the needs of dental technicians, dentists and patients. The company’s ambition to provide the highest quality dental care is as much their guiding principle today, as it was when they first started. In this article, VITA show that they continue to provide worldwide top-quality products and consistent, competent outcomes by presenting two cases using their products namely, VITA ENAMIC and VITA INTERNO Stains. Case1:Glassandhybridceramics combined in one comprehensive restoration! Using the example of a comprehensive restoration in the upper and lower jaw, MDT Björn Czappa (m.c. zahntechnik, Oldenburg, Germany) explains how the materials of glass and hybrid ceramics can be combined in a single restoration, and the aesthetic results that are possible with this technique. In this case study, he also shows how VITA ENAMIC crowns can be characterised with light-curing stains to reproduce the aesthetics of natural teeth. Initial situation The patient had suffered from severe headaches and neck pain for a long time. Ameasurement of the temporomandibular joint confirmed the suspicion of a functional disorder. The anterior maxillary teeth were irregularly abraded, producing an imbalance (Fig. 1.1). The already restored posterior tooth regions also exhibited significant deficits (Fig. 1.2). After making a splint, the patient was pain-free within a short time. Following a successful three-month splint treatment, she then decided on a corresponding complete restoration as a permanent solution. “With the patient case presented here, we embarked on uncharted territory as a dental laboratory. While the anterior teeth of the maxilla were to be restored with pressed glass ceramic (Fig. 1.3), everything in the posterior tooth area called for the VITA ENAMIC hybrid ceramic, which we used for the first time in this case (Fig. 1.4),” reports MDT Björn Czappa. The hybrid ceramic is significantly more elastic compared to traditional dental ceramics and acts as a shock absorber. The VITA ENAMIC posterior tooth crowns weremanufactured using the CAD/CAM process. By MDT Björn Czappa and MDT Heike Assmann
