ABSTRACT The aim of this paper is to show the use of an individual prepared cast post and core on destroyed dental crowns, which after the endodontic treatment serve as non-vital teeth in fixed prosthetic reconstruction. As material we used examinated group of twenty patients from our current practice characterized by strong destruction of dental crowns. After undergone clinical examination and Rtg status, we came to a conclusion that at those teeth, there is an indication for an endodontic treatment. Afterwards, upon preservation of biological recovery of endodontic treatment, non-vital teeth were used for manufacturing cast post and core. Then we have made metal-ceramic crowns which have repaired the defect in the teeth row. Our patients were supervised 6 months (with clinical examination and Rtg status). After the observational period of six months there is not registered wearing off, dislocation of the construction, root fracture or secondary caries. From this supervised cases, we can conclude that each destroyed tooth that can be endodontically treated, and then used in prosthodontics practice, should inevitably be treated and preserved.

These treatments proceed more rapidly with highly predictable results. Therefore, the dental restoration is affirmed as integral part of fixed prosthetic practice in the dentistry after the endodontic tretment. By using the fixed prosthetic reconstruction of endodontic treated teeth, with partial or complete loss of clinical crown, can be established the lost continuity of teeth row, transmission of masticatory pressure, preservation of alveolar bone, occlusal ratio, the periodontal receptor function, as well as aesthetics [1]. At first, the fixed prosthetic reconstruction begins with making a cast - post and core in the dental root canal in order to ensure secure connection with the leftover hard dental tissue. Thus, this provides a proper stress distribution among the tooth, the cast post and core, and the fixed prosthetic construction [2]. The modulus of elasticity of material from which is made the cast post and core, are responsible for smooth stress transmission through the entire dentin. It is therefore important that material to have similar module as the dentin. It can be also rather useful the system, cast post and core - crown, to be made up of material with a similar module of elasticity in order Malaya Journal of Biosciences www.malayabiosciences.com
