Abstract

Objective. To develop a modernized protocol for vertical preparation.

Materials and methods. The study involved 119 patients divided into two groups with vertical and horizontal preparation. The analysis of functional and clinical indicators included an assessment of the Muhlemann-Cowell index, Kulazhenko test and a number of periodontal indices.

Results. Vertical preparation provided a 30% reduction in the loss of hard tooth tissue compared to horizontal, and also minimized the incidence of complications, including gingival inflammation, gingival recession and instability of the marginal fit of the crown. Vertical preparation contributes to the formation of an optimal soft tissue profile, an increase in the height of the crown part of the tooth and an even distribution of the chewing load. The technique has proven its effectiveness, which is confirmed by the improvement of macroretention and durability of orthopedic structures, as well as a reduction in the risk of complications.

Conclusion. The developed protocol of vertical preparation is recommended for implementation in orthopedic practice to improve the quality of rehabilitation of patients with defects in the hard tissues of the teeth, partial adentia and periodontal tissue diseases.
