Screw-retained zirconia crowns with a titanium base are one of the options for implant reconstruction. They allow the mapping of the emergence profile in detail and the creation of conditions to correctly shape the biological width around the implant. With this type of crowns it is possible to reconstruct the emergence profile appropriate for the given clinical conditions, while the appropriate design and material processing of the transmucosal elements provide the proper support for soft tissues. A properly designed and fabricated prosthetic reconstruction is important in maintaining the long-term, positive effects of treatment. In practice this translates into maintaining the soft tissues in their proper form, without signs of inflammation, as well as maintaining the pre-determined, fixed bone level of the alveolar process around the implant. These factors have a direct impact on the long-term retention of the restoration and its full functionality. The constant development in the methods of fabricating ceramic crowns is largely dictated by the search for such materials and their combinations that, while ensuring maximum aesthetic benefits, will also be fully functional, resistant to damage and chipping. The purpose of this article is to present the principles of designing the transmucosal element and methods of fabricating the supragingival element of these crowns.
