Abstract

Razvoj vlaknima ojačanih kompozitnih materijala omogućio je nova terapijska rješenja i proširio indikacije za izradu direktnih restauracije čak i u slučajevima opsežnijeg gubitka tvrdih zubnih tkiva ili čak samog zuba. Spomenuti materijali imaju poboljšana fizičko-mehanička svojstva u usporedbi s klasičnim kompozitnim materijalima
Nakon provjere kvaliteta punjenja korijenskih kanala rtg snimkom, uklonio se privremeni ispun. Suho radno polje osigurano je zaštitnom gumenom plahticom. Proveden je adhezijski postupak (G Premio Bond, GC, Tokio, Japan), nakon čega je adheziv polimeriziran 20 sekundi. U kavitet je postavljen kompozitni materijal ojačan vlaknima (everX Posterior, GC, Tokio, Japan) u slojevima debljine 4 mm. Kao završni sloj, debljine tri milimetra,postavljen je standardni kompozit (Gradia Direct Posterior, P-A2, GC, Tokio, Japan),u slojevima od 2 mm. Nakon uklanjanja gumene plahtice, usklađena je okluzija i artikulacija te je provedena završna obrada i poliranjeispuna.
U opisanom prikazu slučaja, kod endodontski liječenog donjeg kutnjaka, direktna restauracija zuba je napravljena kombinacijom vlaknima ojačanog i klasičnog kompozitnog materijala kako bi se ojačala preostala struktura zuba te spriječio lom zuba i/ili korijena koji bi mogao dovesti do neuspjeha restauracije i gubitka zuba.

Abstract (english)

Development of fiber reinforced composite materials has enabled new treatment solutions and wide range of indications for direct restorations even in cases with extensive loss of hard dental tissues or tooth loss. These materials have better physico-mechanical properties in comparison to standard composite materials.
After root canal filling temporaril was evaluated on x-ray, temporary filling was removed and the tooth was isolated with rubber-dam. Adhesive resin was placed (G Premio Bond, GC, Tokio, Japan) and polymerized for 20 seconds. The cavity was filled with 4 mm thick layers of fiber-reinforced composite material (everX Posterior, GC, Tokio, Japan) and light-polymerized 20 seconds. Standard composite (Gradia Direct Posterior, P-A2, GC, Tokio, Japan) was used for final layer in 2 mm thick layers. After rubber-dam was removed, occlusion and articulation were adjusted and the filling was finished and polished
In this case report, endodontically treated lower molar was restored with direct restoration using combination of fiber reinforced and standard composite material in order to reinforce the remaining tooth structure and prevent the fracture of the crown and/or the root which could lead to the failure of restoration and tooth loss.
