Tools and methods of preparing a post-canal for restoration of the endodontically treated teeth with shattered crown

Abstract

Summary. Restoration of the teeth with the massive losses of dental hard tissues after endodontic treatment is an actual problem of dentistry. Restorations represent considerable difficulties, because: 1. We deal with significant destructions of crowns owing to pathological process / mechanical trauma; 2. After endodontic treatments diameter of the main root canal increases approximately twice. 3. The appearance at the last ten years of non-metallic posts and dental restoration materials of the last generation (double-cured flowable composite or double-cured/ triple-cured glassionomer cements), create the condition for development of modern clinical decisions of the maximum biocompatibility. Corresponding technologies demand: 1. Use of special tools, procedures and methods in preparing of dowel space — so-called “post space” or “post-canal”; 2. A concrete definition of the purposes, aggravating factors, indications and contra-indications, recommendations and techniques.
