AB  - PMMA poly(methyl methacrylate) has a large spectrum of uses as bone cements, in dentistry as denture base materials and other industrial applications. One of the main drawbacks of these materials is the residual monomer that is proven allergen and irritant. It was shown that addition of dimethyl itaconate (DMI) to the PMMA denture base systems decrease the quantity of residual monomer but, also deteriorate mechanical properties. The addition of alumina fillers in the PMMA/DMI produced composite materials results in improved mechanical properties compared with pure PMMA and additionally reduces the level of residual monomer in the composition.

AB  - 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 properties 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.
AB  - 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 matricu 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.

AB  - Alumina based particles were prepared from aluminium chloride hydroxide as starting material by sol-gel technique. One series of particles was doped with ferrous oxide. Both series of particles were calcinated at three different temperatures: 700 degrees C, 800 degrees C and 900 degrees C. Poly(methyl methacrylate), PMMA, was used as a matrix and two different types of alumina based particles were added into the matrix to form the composites. All composites consisted of 3 wt% of alumina based particles. The aim of this study was to examine whether and how the temperature of particle calcination affects the microhardness and mechanical properties of the composite. The particles were characterized by the X-ray diffraction (XRD) and physical absorption methods. The morphology of the composites was examined using a field emission scanning electron microscope (FESEM). The microhardness of composites was measured using a traditional Vickers hardness (HV) method. The mechanical characteristics of obtained composites were determined using tensile test and impact testing.
