Abstract

Restauracija endodontski liječenih zuba i dalje predstavlja izazov. Uspjeh terapije i preživljavanje zuba najviše ovisi o kvaliteti restauracije. Kod izbora vrste restauracije glavni čimbenik trebala bi biti količina preostalog zubnog tkiva.
Direktne restauracije uglavnom su jednostavnije. Potreban je jedan posjet liječniku i jeftinije su za pacijenta. Indirektne restauracije imaju bolja fizičko-mehanička svojstva te, za razliku od direktnih restauracija, polimerizacijsko skupljanje kompozita ne dovodi do razvoja stresa na stijenkama kaviteta.
U ovom radu prikazana su tri klinička slučaja izrade restauracija kod endodontski liječenih zuba. U prvom slučaju prikazana je izrada direktnog kompozitnog ispuna s dentinskom jezgrom od kompozita ojačanog vlakima kako bi se ojačala preostala struktura zuba te spriječio lom krune i/ili korijena koji bi mogao dovesti do gubitka zuba. Drugi slučaj prikaz je otvorene “sandwich” tehnike za koju su korišteni kombinacija staklenoionomernog cementa i kompozita. Otvorena “sandwich” tehnika korištena je zbog subgingivnog smještaja ruba preparacije, tj. zbog nemogućnosti osiguravanja suhog radnog polja. Treći slučaj prikazuje izradu kompozitnih mostova na distalnim zubima te nadogradnju prednjih zuba. Kompozitni mostovi ojačani su staklenim vlaknima te im je jezgra izraĎena od kompozita ojačanog vlaknima kako bi im se poboljšala fizičko-mehanička svojstva.
Razvoj materijala i nove spoznaje o svojstvima endodontski liječenih zuba otvaraju nove mogućnosti u restauraciji endodontski liječenih zuba. U prikazanim kliničkim slučajevima odabrani su materijali i tehnike za izradu direktnih i indirektnih restauracija kako bi se osigurali uspjeh i dugotrajnost restauracija te preživljavanje endodontski liječenih zuba.

Abstract (english)

The restoration of endodontically treated tooth still remains a challenge. The success of therapy and tooth survival depend primarily on the quality of restoration. The most important factor for choosing the type of restoration should be the quantity of the remaining tooth structure.
Direct restorations are more easily made, only one visit is required and they are cheaper for the patient. Indirect restorations have better physico-mechanical properties, and, in comparison to direct restorations, polymerization shrinkage of composites does not produce stress on cavity walls.
In this case report, three clinical cases of restoring endodontically treated teeth are shown. In the first case, a direct composite restoration with fiber reinforced composite core is shown. The fiber reinforced composite was used to reinforce the remaining tooth structure and reduce the possibility of crown and/or root fracture, that could lead to tooth loss. In the second case, open “sandwich” technique is shown, where a combination of glass ionomer cement and composite is used. Open “sandwich” technique is used, because preparation of the cavity was under gingival margin and dry working field could not be ensured. In the third case, composite bridges in the posterior region and a restoration of the frontal teeth are shown. The composite bridges are fiber reinforced and their base is made from fiber reinforced composite to enhance their physico-mechanical properties.
Development of materials and new findings about properties of endodontically treated teeth open up new possibilities for restoration of endodontically treated teeth. In the presented clinical cases, materials and techniques were used for direct and indirect restorations in order to ensure the success and longevity of the restoration as well as the survival of endodontically treated teeth.
