Tooth preparations without a defined finish line have been termed in several different ways, such as knife edge, feather edge, shoulderless, more recently “bopt". With slight differences between each other, all this preparation types may be defined “vertical” as opposed to “horizontal” ones (shoulder, chamfers) and since the introduction of metal ceramic they have been almost abandoned, with limited exceptions (i.e.: periodontically involved abutments). From a biological standpoint, preserving a maximum amount of sound tooth structure, as it is done in vertical preparations, might also offer a more conservative alternative to a horizontal margin design in other clinical conditions such as endodontically treated teeth, vital teeth in young individual, teeth affected by caries at the cervical third. Vertical margins on zirconia crowns have been tested in vitro and clinical reports have been published. A re-evaluation of possible advantages and shortcomings of vertical preparation design in contemporary prosthodontics, especially in full digital workflows, will be presented in light of clinical experience and existing literature.
Course objectives that attendees can expect to learn from the presentation: 
1.To define geometrical and biological characteristics of vertical preparations as compared to horizontal ones.
2.To analyze current in vitro literature regarding zirconia and vertical preparations.
3.To evaluate available clinical data regarding zirconia and vertical preparations.
