The article presents an analysis of the effectiveness of CAD/CAM technologies in the direct prosthetics of severely damaged teeth using vertical preparation technique. Using the example of a clinical case of restoration of a premolar of the upper jaw with subgingival location of the destruction boundaries, a complete digital treatment protocol is demonstrated, including the manufacture of an individualized pin structure, a temporary crown and permanent restoration. The advantages of digital technologies in solving complex clinical problems associated with non-standard root canal anatomy and significant loss of the tooth crown are shown. Using the MEDIT i700 intraoral scanner, milling technology, and selective laser melting, the possibility of precision fabrication of temporary and permanent structures has been demonstrated, taking into account the specifics of the clinical situation. The results of a three-week observation confirm the high efficiency of using CAD/CAM technologies, demonstrating the stability of the functional and aesthetic characteristics of the restoration, optimal adaptation of periodontal tissues and a high level of patient satisfaction. Particular attention is paid to the possibility of controlling the geometry of the structure at the stage of digital modeling, which is critical when working with subgingival location of the preparation boundaries.
