Abstract

Svrha ovog rada je prikazati na kliničkom slučaju prednosti i mogućnosti primjene vlaknima
ojačanih kompozitnih materijala za izradu direktnih restauracija. Kod pacijenta muškog spola i
starosti 27 godina koji je upućen na Zavod za endodonciju i restaurativnu stomatologiju
Stomatološkog fakulteta Sveučilišta u Zagrebu zbog revizije endodontskog liječenja donjeg
lijevog drugog kutnjaka, provedena je revizija te se pristupilo izradi direktne restauracije kako
bi se nadoknadila izgubljena... More zubna tkiva te povratila zubu morfologija i funkcija. Prilikom
izrade restauracije, za dentinsku bazu korišten je kratkim staklenim vlaknima ojačan
kompozitni materijal GC everX Posterior u kombinaciji sa standardnim kompozitom (Essentia
Universal) pomoću kojeg je rekonstruirana morfologija zuba. Staklenim vlaknima ojačani
kompoziti imaju mehanička svojstva koja odgovaraju svojstvima dentina, povećavaju otpornost
zuba na loma, a mogu i spriječiti napredovanje frakture zuba ili ispuna prema dubljim
dijelovima zuba i/ili korijena zuba. U prikazanom kliničkom slučaju, postavljena je direktna
restauracija kombinacijom staklenim vlaknima ojačanog kompozita i standardnog kompozita
budući da je zub endodontski liječen te je bio prisutan opsežan gubitak tvrdih zubnih tkiva, a
osim toga, zub je u regiji kutnjaka gdje se očekuju najače sile tijekom funkcije te se odabranim
materijalima pokušala smanjiti mogućnost loma i vertikalne frakture korijena te posljedično
gubitak zuba. Less

Abstract (english)

The aim of this thesis is to present a clinical case in order to show the advantages and
possibilities for use of fiber-reinforced composite (FRC) materials for direct restoration. A male
27-year-old patient was referred to the Department of Endodontics and Restorative Dentistry,
School of Dental Medicine University of Zagreb for an endodontic retreatment of his left
mandibular second molar. Following the retreatment, a direct restoration was planned in order
to restore tooth... More morphology and function. During restorative procedure, GC everX Posterior
short glass fibre-reinforced composite was used as dentin base, in combination with a standard
composite (Essentia Universal) for final reconstruction of tooth morphology. Mechanical
properties of glass FRC match the properties of dentin, improve tooth fracture resistance, and
can help prevent propagation of fracture line in hard dental fissures or filling. The clinical case
presented, direct restoration was placed using combination of FRC and standard composite
since the tooth was endodontically treated with extensive loss of hard dental tissue. Moreover,
the tooth in question was a molar, therefore, as one can expect the highest occlusal forces in the
posterior region, the materials chosen were used in order to minimise the possibility for
infractions, fractures and vertical root fracture and consequently, prevent tooth loss. Less
