Abstract
Dental materials have specific requirements regarding behavior in exploitation conditions. Poly (methyl methacrylate) (PMMA) is one of the most commonly used prosthetic materials. It is of interest to improve the mechanical properties of the polymer matrix by adding reinforcements in the form of ceramic particles. It has been shown that adding very small amounts of particles to the material, substantially improved mechanical properties of PMMA modified by dimethyl itaconate (PMMA/DMI). In this paper, different sorts of alumina fillers will be examined. Commercial alumina particles and micro particles of alumina obtained from the sol-gel technique influence the mechanical properties of the composite material obtained. Sol-gel techniques was the mean to synthesize pure alumina particles and ferrous oxide doped alumina particles. Composites are prepared with 1 wt. %, 3 wt. % and 5 wt. % of alumina based particles. It has been shown that all the tested fillers improve the flexular properti...es of the material relative to the pure matrix PMMA/DMI and the most suitable concentration of fillers was 1 wt. %. Among the types of fillers tested alumina particles obtained by sol-gel technique, perfomed in the best way in improving the flexural strength and modulus.

Dentalni materijali imaju posebne zahteve u vezi sa ponašanjem u uslovima eksploatacije. Poli(metil metakrilat) (PMMA) predstavlja jedan od često korišćenih materijala u protetici. Od značajnog je interesa da se poboljšaju mehanička svojstva polimerne matrice dodatkom ojačanja u obliku keramičkih čestica. Pokazalo se da se dodavanjem veoma malih količina čestica u materijal dobijaju bitno poboljšana mehanička svojstva PMMA modifikovanog dodatkom dimetil itakonata (PMMMA/DMI). U okviru ovog rada ispitaće se kako utiče dodatak komercijalnih nanočestica aluminijum oksida i mikro čestica aluminijum oksida dobijenih sol-gel tehnikom na mehanička svojstva dobijenog kompozitnog materijala. Sol-gel tehnikom sintetisane su čiste aluminijum oksidne čestice i čestice dopirane gvožđe oksidom. Pripremeljeni su kompozitni materijali sa 1 mas. %, 3 mas. % i 5 mas. % čestica na bazi aluminijum oksida. Pokazano je da svi testirani punioci poboljšavaju savojna svojstva materijala u odnosu na čistu matri...cu PMMA/DMI i da je najpogodnija količina čestica 1 mas. %. Između svih vrsta dodatih čestica, mikro čestice aluminijum oksida dobijenih sol-gel tehnikom su pokazale najbolje vrednosti poboljšanja savojne čvrstoće i modula.
