Sažetak
Kao jedan od faktora uticaja na jačinu veze postavljenih ortodontskih bravica za zube može biti dužina trajanja ortodontske terapije. Cilj ove eksperimentalne studije in vitro, bio je da ispita jačinu veze između bondiranih ortodontskih metalnih bravica fiksiranih različitim adhezivnim sredstvima i površine gleđi zuba u različitim vremenskim intervalima. U ovoj studiji korišćena su tri različita tipa adhezivnih materijala Heliosit (Ivoclar-Vivadent, Lichtenstain), Fuji Ortho LC (Japan), System 1+ (Dentaurum, Germany) i njihov uticaj na jačinu veze bondiranih ortodontskih bravica za zube u različitim vremenskim intervalima. Prosečne jačine veza u sve tri ispitivane grupe pokazuju porast nakon 15 dana od bondiranja ortodontskih bravica za zube, a zatim i neznatno smanjenje u jačini veze nakon 30 dana od njihovog postavljanja. Na osnovu rezultata ispitivanih prosečnih vrednosti jačina veza može se zapaziti zajednička karakteristika sva tri ispitivana adhezivna materijala, a to je da je nakon 24 sata od postavljanja bravica, jačina veza najslabija, nakon 15. dana, vrednosti jačine veza dostižu svoj maksimum, dok nakon 30. dana, opada u sve tri ispitivane grupe.
