Abstract

Vertical preparation techniques (VPT) have gained popularity in restorative dentistry due to their conservative approach to preserving tooth structure and improving aesthetic outcomes. Purpose of this article is to discuss the advantages and disadvantages of the vertical tooth preparation technique, as well as to provide evidence-based recommendations for its clinical application, based on the analysis of a specific clinical case. This study is based on a comprehensive review of relevant literature and is further supported by the detailed analysis and discussion of a specific clinical case. Conversely, when preparing teeth with intact periodontal structures, we advocate for the use of the horizontal preparation concept. In addition, we will present the results of our own clinical research. As can be seen from the clinical case we have presented, the vertical preparation method is very effective for deep, subgingival fractures of the hard tissues of the crown part of the tooth. This method allows to obtain the most correct marginal fit in the fracture zone and facilitate the integration of the edge of the artificial crown to the periodontal tissues. It should also be noted that we believe that the most effective use of zirconium artificial crowns is in combination with vertical preparation, since the bacteriophobic properties of zirconium contribute to faster and more adequate integration of the edge of the artificial crown to the periodontal tissues. The vertical margin preparation technique proves to be effective when managing teeth affected by periodontal pathology. However, in cases involving intact periodontal tissues, horizontal marginal adaptation demonstrates greater clinical efficacy. We recommend the use of the vertical preparation technique in cases involving teeth with compromised periodontal support.
