Abstract
Aim and objectives: This study will try to emphasize the differences between different materials and technologies currently used for dental crown manufacturing. Materials and methods: We performed 4 different types of dental crowns, using different materials and technologies, on the same preparation, on 4 different duplicate models, and we examined the marginal adaptation and the surface quality, using a HD camera. Results: The worst results, both in marginal adaptation and surface quality, were found to be present in the crowns manufactured in the traditional casting and waxing manner. Discussions: The traditional procedures, which involve casting and waxing, are many times subject to human error and are also affected by many physical factors, which are harder to control. Conclusion: Regardless on the material chosen – metal, ceramic or zirconia, the CAD-CAM technology offers better properties to the final restorations and, thus, more safety to the clinician and to the dental technician.
