Abstract

Frakture i destrukcije kruna endodontski tretiranih zubi susreću se u svakodnevnoj stomatološkoj praksi. Rješavanje ovakvih slučajeva postiže se primjenom intrakanalnih kolčića. U uporabi su već više od 200 godina i neprestano se razvijaju sa svrhom
postizanja što boljih biomehaničkih i estetskih svojstava. Mogu biti lijevani i konfekcijski, metalni i bezmetalni (keramički i kompozitni sustavi). Kolčići od bezmetalnih estetskih materijala sve se više koriste zbog svojih odličnih estetskih i fizikalnih svojstava, ali i zbog brzine i jednostavnosti primjene te ekonomske prihvatljivosti. Keramički sustavi su estetski vrlo dobri, ali su zbog visokog modula elastičnosti pretvrdi za površinsku obradu. Kompozitni sustavi su sustavi pojačani vlaknima, čime se postiže značajno poboljšanje mehaničkih svojstava u odnosu na keramičke sustave. Biokompatibilni su, modula elastičnosti sličnog dentinu, što omogućava stvaranje jedinstvene cjeline potrebne za izradu trajnog nadomjeska. Osim duljine, širine i vrste kolčića, za maksimalnu retenciju bitna je i uporaba kompozitnih cemenata i adhezijskih sustava. Kompozitni kolčići pojačani staklenim vlaknima, uz odgovarajuće cemente i adhezijske sustave, s estetskog i biomehaničkog stajališta najbolje su rješenje za rekonstrukciju zubne krune nakon endodontskog tretmana.

Abstract (english)

Fractures and destruction of crowns of endodontally treated teeth are seen daily in dental practice. Resolving such cases is achieved with the application of a pin into the tooth canal. Pins have been in use for over 200 years and are constantly developing towards providing better biomechanical and aesthetic characteristics. They can be specially made or ready made, metal or non-metal (ceramic or composite composition). Non-metal pins made of aesthetic materials are being
increasingly used due to their excellent aesthetic and physical characteristics, as well as due to their fast and simple application and economic acceptability. Ceramic pins are aesthetically very good, however, due to the high module of
elasticity, they are too hard for superficially processing. Composite systems are systems reinforced with fibres, which therefore achieves a significantly improved mechanical characteristic in comparison to ceramic systems. They are biocompatible and their elasticity module is similar to that of dentin, such which allows for the creation of a single entity necessary for the creation of a permanent implant. In addition to length, width and type of pin, the use of a composite cement and adhesive system is essential for maximal retention. From the aesthetic and biomechanical perspective, composite pins strengthened by glass fibres with the appropriate cement and adhesive structures are the best solution for the reconstruction of teeth crowns following endodontal treatment.
