Abstract (en)
Dental adhesives have an important role in the field of restorative dentistry providing innovative solutions and comfort for the patient. The importance of the quality of the material as well as the adhesion to the substrate are of main importance now days. This thesis deals with composite materials having improved mechanical properties and providing better adhesion to the substrate. The adhesion of the classical composition of photo-polymerizing methacrylate can be improved using the alumina based fillers. It is shown that the substantial improvement is obtained using the chemical modification of fillers composition, and additional improvements are achieved by introduction of the surface modifications on the filler particles. The adhesion is tested using the modified method that uses the hardness measurements to measure adhesion and those results are compared to the wetting angle measurements and to cavitation properties of the composite films. Obtained results suggest that adhesion as well as composite mechanical properties are improved using the selected method.
Abstract (sr)
Dentalni adhezivi imaju značajnu ulogu u restorativnoj stomatologiji dajući inovativna rešewa I omogućavajući bolji komfor za pacijenta. Značaj kvaliteta materijala, kao I kvliitet adhetije za substrat su posebno značajni u naše vreme. Ova doktorsa disertacija bavi se kompozitnim materijalima koji imaju poboljšana mehanička svojstva I istovremeno boboljšana adhezivna svojstva. Adhezivna svojstva polimera koji se koriste kao adheziv u stomatologiji koji su u stvari fotopolimerizujući metaakrilati mogu se boboljšati dodavawem punilaca na bazi aluminijum-oksida. Pokazano je da se značajna poboljšanja mogu postići hemijskim modifikacijama punilaca, a dodatno se mehanička svojstva I adhezivnost ogu poboljšati površinskom modifikacijom čestica. Adhezija je ispitivana modifikovanom metodom koja je zasnovana na merenju mikrotvrdoće I ovi rezultati upoređeni su sa ostvarenim uglovima kvašewa I svojstvima otpornosti na kavitaciju. Dobijeni rezultati ukazuju da se adhezija kao I mehanička svojstva mogu poboljšati korišćenjem odabranih metoda.
