The development of restoration methods of devitalized teeth, destructed due to pathological processes, is a highly topical problem of modern dentistry.
Objectives. To study the efficacy of treating patients with fallen out crowns by means of composite-reinforced stump posts.
Material and methods. We have developed a composite-reinforced post and core (CRPC) construction using primary and supplementary fiber-optic pins (FOP), which enhance stump retention, distribute the load properly and thus strengthen the system itself, and have offered it for practical application.
In order to compare and assess the effectiveness of the suggested post and core construction, a composite inlay (CI), reinforced with a single FOP, and a cast post and core (CPC), made of cobalt-chromium alloy, we have been examining and studying the condition and changes of the constructions compared for four years.
Results. The article presents the results of clinical examination of 143 patients having complete crown defects for whom 190 post and core constructions have been made, including 69 inlays (36,32%) manufactured according to the suggested technique.
The data received evidence high clinical efficacy of treatment provided for patients with complete loss of crowns using CRPCs. The application of the suggested post construction eliminates such significant complications as post and core or root fracture, decementation of dental protheses.
The application of the above-mentioned composite-reinforced post and core constructions in treatment of patients with complete loss of crowns allowed to achieve satisfactory prosthodontic treatment results and to avoid complications within the remote period of time in 97,1% of cases, while upon the usage of the known treatment methods the complications were absent only in 80 and 81,97% of all cases.
Key words: hard dental tissues defects, post and core construction, composite-reinforced stump post.
