Poggio DDS, MS Orth, PhD, is Active Member of the Italian Academy of Prosthetic Dentistry (AIOP), of the Italian Society of Orthodontics (SIDO) and of the Italian Society of Periodontology and Implantology (SIdP). Associate Fellow of the Academy of Prosthodontics. Visiting professor in the Postgraduate Program of Orthodontics of the University of Milan (Italy) and in the Departments of Prosthodontics of the universities of Siena (Italy) and Rochester (NY). President Elected of the Italian Academy of Prosthetic Dentistry (AIOP) for 2019-2020 and member of the Executive Board of the American Prosthodontic Society. He is in private practice in Milan but maintains research and publishing activity (H-index 20).

Synopses 1
Interdisciplinary treatment management is a common treatment modality in patients with severely mutilated dentitions as well as in those with more limited clinical conditions but with high esthetic demands. Unfortunately quite often the interaction between different specialties may lead to additional problems instead of additional solutions and treatment management may be frustrating: “fuzzy” exposure to even the highest state of the art treatment in each discipline may result in far from ideal results. Strategic multidisciplinary or interdisciplinary management and planning  is necessary to maximize treatment results by synergizing the knowledge, skills and possibilities of all the different dental disciplines.

Synopses 2
Vertical tooth preparations without a defined finishing line (knife edge, feather edge, or shoulderless) are an alternative to “horizontal” ones (shoulder, chamfers). Preserving the maximum amount of sound tooth structure, as it is done in vertical preparations, offers a more conservative alternative to a horizontal margin design in clinical conditions such as periodontally involved teeth, endodontically treated teeth, vital teeth in young individual, teeth affected by caries at the cervical third. Moreover vertical preparations allow for a simplification of prosthodontic procedures. Vertical margins on ceramic crowns have been tested in vitro and clinical reports have been published. A re-evaluation of advantages of vertical preparation design in contemporary prosthodontics will be presented in light of clinical experience and with the support of recently published literature.
