Abstract

“Invisible Single Tooth Replacement” in the Esthetic zone has been considered for decades one of the pinnacles of Implantology. This procedure embraces surgical aspects of both hard and soft tissue preservation, reconstruction & remodeling. Implant, connection and abutment design play an important role as well, and recent Prosthodontic advances in the field metal-free CAD-CAM technology with materials like Zirconia, Alumina and Lithium Di-Silicate created an Esthetic and Biological breakthrough. Going through the Gingival section from the neck of the implant towards the visible part of the Emerging tooth-like restoration, the team technician-clinician has to position up to four different interfaces between the different components and materials in this 3-4mm of running space. They have to widen also substantially the emergence profile going from a narrow connection to a much wider anatomical perimeter crossing different layers of soft tissue, every layer with its own specific characteristics and features. At the end of this process, stable crestal bone levels remain still today one of the most wanted features of successful implant treatment.

The Lecture addresses the key elements on the way to excellence where the different pieces of carefully designed hardware have to respect the layer-specific tissue features to obtain long-lasting clinical stability.
