Abstract

The study evaluated the importance of minimally invasive protocols in orthopedic dental treatment, which is to increase prognostic assessment functioning level of teeth, as support units of orthopedic structures, and the orthopedic structures themselves, taking into account the specifics of their design and laboratory use modeling and milling. The aim of the study. Analyze and justify the use of minimally invasive approaches to the preparation of teeth for different types of orthopedic structures. Materials and methods of research. For science research we were using comparative models preparation designs of single teeth for metal-ceramic crowns, all-ceramic crowns, all-zirconium crowns and design of preparation for veneer (single-surface veneer) or partial orthopedic restoration (inlay, half-crown). Preparations were performed on gypsum tipodont models, from which digital impressions were previously obtained using a laboratory scanner.  After performing the preparatory study, the models are re-scanned and the obtained digital images in the *.stl format are interchanged before and after the corresponding control reduction of the simulated teeth hard tissues. Results of the research. The obtained results indicate that the greatest actual volume of excessive reduction of teeth hard tissues is observed in cases of preparation of such under different types of full-contour crowns, especially in cases of canines, premolars and molars. Conclusions. There are two separate areas of minimizing the amount of interventions when using different types of orthopedic structures, which include: 1) replacement of certain types of structures with other mini-invasive in their design; 2) minimization of the amount of directed reduction in the conditions of use of all types of orthopedic constructions by implementation of appropriate control measures during preparation.
