Utjecaj biomehaničkih čimbenika na nadograđivanje devitaliziranih zuba

Restoration with post and cores for fractured clinical crowns on devitalized teeth is the treatment procedure frequently used in the clinical practice of specialists and dentists in primary health care. The paper deals with prosthetic reasons for teeth devitalization and making of post and cores, particularly when a comparatively large rests of the clinical crown are preserved, along with the indications and contraindications for their placement on devitalized teeth. Influence of biomechanical factors is analyzed with regard to post and core retention and stress distribution over the hard dental tissue and surroundings, depending on possible variations in preparation width and length, particularly in the radicular part, for different types of post and cores. In conclusion, the authors express their preference for individual post and core placement over prefabricated, and highlight the importance of correctly determined indication for post and core, successful selection of the type of post and core and correct treatment for extension of the lifetime of the fixed prosthetic work on the endodontically treated tooth.
