POSTENDODONTIC TOOTH TREATMENT

Endodontskim zahvatom smanjena je otpornost preostalog zubnog tkiva na sile vlaka i tlaka. Zato je nužno odgovarajućom resturacijom obnoviti zubnu krunu, vratiti morfološki oblik i funkciju. Potrebno je pravodobno primijeniti odgovarajuću, indiciranu terapiju. U protivnom možemo zub čak i izgubiti zbog prodora bakterija u periapeks ili frakture. Endodontski adekvatno sanirane zube kojima nedostaje supragingivna struktura nužno je opskrbiti intrakanalnim kolčićima kako bi se uspostavila koronarna zubna struktura koja će retinirati restauraciju i sudjelovati u prijenosu sila s resturacije na korijen. Danas se sve više koriste kolčići izrađeni od estetskih materijala, keramički i kompozitni, koji se u korijenski kanal cementiraju adhezijskom tehnikom. Vlaknima ojačani kompozitni materijali razvijeni su s ciljem stvaranja novih materijala poboljšanih svojstva. Vlaknima ojačane nadogradnje već su neko vrijeme prisutne u dentalnoj medicini kako bi se prevladali nedostaci koji se javljaju pri upotrebi metalnih lijevanih nadogradnji. One posjeduju modul elastičnosti sličan dentinu, estetske su, ne korodiraju, moguća je izrada i cementiranje tijekom jednog posjeta stomatologu, a u slučaju loma nadogradnje ili revizije punjenja korijenskog kanala mogu se jednostavno ukloniti. Cilj ovoga poslijediplomskog rada je opisati mogućnosti i problematiku endodontske opskrbe zuba i prikazati dosad objavljene rezultate i spoznaje dobivene laboratorijskim i kliničkim istraživanjima svojstava vlaknima ojačanih nadogradnji.Endodontically treated teeth lack resistance of tension and pressure forces. Therefore, it is essential to apply appropriate restoration to restore the tooth structure, as well as its morphological shape and function. Unless the proper, indicated therapy is applied, you may run the risk of losing the tooth due to bacteria invasion or fracture. If teeth which have been properly, endodontically treated, but lack supragingival structure, intracanal posts will have to be supplied to re-establish coronal tooth structure. This procedure will not only retain the restoration but also enforce the transfer from the restoration to the root. Posts, which are increasingly being used in modern treatment, are made of aesthetic materials, such as ceramic and composite, and are cemented in the root canal by an adhesive. Fibre-reinforced composite was made from fibres and matrices in order to create a new material with improved features. Fibre-reinforced posts have been present in dentistry for some time now and have been developed to overcome problems common in the clinical usage of cast post. They have an elastic modulus similar to that of dentine and apart from being aesthetic, they do not corrode. Bearing this in mind, immediate chairside post fabrication and cementation is possible in a single visit . In case of fracture, or endodontic re-treatment, the removal of fibre-reinforced posts is simple. The aim of this paper is to describe the possibilities and problematic issues regarding an endodontically supplied tooth as well as to present established publications of results and perceptions achieved by laboratory and clinical research into fibre-reinforced posts
