Graduate Student from the Branch of Medical and Industrial Materials Science Earns a Master's Degree for Research on Enhancing Denture Base Properties Using Nanoparticles
The Branch of Medical and Industrial Materials Science awarded a Master’s degree to the graduate student Iman Alwan Arhim for her thesis titled:
“Improvement of Mechanical and Antimicrobial Properties of Denture Base By Adding Nanoparticles Materials"
The defence was held in the late Professor Dr Abdul-Muttalib Ibrahim Al-Sheikh Hall at the department building.Examination Committee consists of:
- Prof. Dr. Ali Abadi Al-Taif Department of Applied Sciences / Medical and Industrial Materials Science Branch – Chair
- Asst. Prof. Dr. Athraa Ali Mahmoud Al-Mustansiriya University / College of Dentistry – Member
- Lect. Dr. Mohammed Salman Kazem Department of Applied Sciences / Laser Science and Technology Branch – Member
- Lect. Dr. Manal Abdulwahid Aboud Department of Applied Sciences / Medical and Industrial Materials Science Branch – Member & Supervisor
- Dr. Halima Thajeel Halboos Ministry of Science and Technology / Materials Research Directorate – Member & Supervisor
In this study, the effect of incorporating nanoparticles (silver, titanium oxide, and zirconium oxide) on some mechanical properties—flexural strength, impact strength, surface hardness, compressive strength, and surface roughness—of polymethyl methacrylate (PMMA) used in denture fabrication, was investigated. Additionally, the effect of nanoparticle incorporation on antimicrobial properties was examined. The samples were divided into three groups based on the nanoparticle addition ratio: (silver: titanium oxide) and (silver: zirconium oxide). A fixed weight percentage (0.3%) of silver nanoparticles was added, while titanium oxide and zirconium oxide were added in varying proportions (0.1%, 0.3%, and 0.5%). Moreover, a third group of samples was prepared, incorporating 0.3% silver and (0.05%, 0.15%, 0.25%) of both titanium oxide and zirconium oxide to study the combined effect of nanoparticles on PMMA properties. X-ray diffraction (XRD) was used to analyze the structural properties of the nanoparticles. Additionally, surface morphology was examined using a field emission scanning electron microscope (FESEM), while an atomic force microscope (AFM) was employed to assess surface roughness. The results showed that incorporating silver and titanium oxide nanoparticles enhanced the flexural strength, with the highest value (76.62 MPa) observed at 0.3% Ag + 0.3% TiO2. Meanwhile, adding ZrO2 resulted in a slight improvement, reaching (71.83 MPa) at 0.5% ZrO2. The combination of nanoparticles yielded the highest flexural strength value (89.35 MPa) at 0.3% Ag + 0.15% (TiO2 - ZrO2). Surface hardness increased for all samples with nanoparticle incorporation, reaching peak values of (85.3) and (85.5) at 0.3% Ag + 0.3% TiO2 and 0.3% Ag + 0.5% ZrO2, respectively, compared to (81.2) for pure PMMA, adding silver and titanium oxide improved impact strength, achieving the highest value (7.54 kJ/m²) at 0.3% Ag + 0.3% TiO2, compared to (6.81 kJ/m²) for PMMA. A similar trend was observed when combined nanoparticles, with the highest impact strength (7.14 kJ/m²) at 0.3% Ag + 0.15% (TiO2 - ZrO2). However, ZrO2 addition reduced impact strength at all concentrations, with the lowest value (5.49 kJ/m²) recorded at 0.1% ZrO2. The results showed that compressive strength increased with nanoparticle incorporation, with the highest value (147.07 MPa) observed at 0.3% Ag + 0.5% ZrO2, followed by (132.3 MPa) at 0.3% Ag + 0.5% TiO2, compared to (98.01 MPa) for PMMA. However, Young's modulus decreased with increasing nanoparticle concentration, with the lowest value (415.18 MPa) recorded at 0.3% Ag + 0.25% (TiO2 - ZrO2), compared to (616.44 MPa) for PMMA. Surface roughness significantly improved with nanoparticle incorporation, with the best value (0.2917 µm) observed at 0.3% Ag + 0.3% TiO2, compared to (0.7556 µm) for PMMA, followed by (0.3453 µm) at 0.3% Ag + 0.3% ZrO2. The antimicrobial activity study revealed that adding 0.3% Ag + 0.25% (TiO2 - ZrO2) exhibited the highest microbial inhibition. Furthermore, the inhibitory effect against Streptococcus mutans was more significant than its effect against Escherichia coli at all tested concentrations. .

The dissertation defence took place in the late Professor Dr. Abdul-Muttalib Ibrahim Al-Sheikh Hall within the department building. The defence committee consisted of:
- Professor Dr. Ghazi Kamal Saeed - University of Wasit / College of Basic Education (Chair)
- Professor Dr. Shehab Ahmed Zidan - Applied Sciences Department / Medical and Industrial Materials Science Branch (Member)
- Professor Dr. Enas Mohi Hadi - Applied Sciences Department / Medical and Industrial Materials Science Branch (Member)
- Assistant Professor Dr. Sadeer Mowaffaq Majeed - Applied Sciences Department / Medical and Industrial Materials Science Branch (Member)

This study aimed to prepare glass samples and convert them into glass-ceramic samples, compare their structural, optical, and mechanical properties, and evaluate their potential for radiation shielding applications. The glass samples were synthesized using the melt-quenching method, with the composition: (50−x)B2O3−25TeO2−25BaO−xDy2O3(50-x) B_2O_3 - 25TeO_2 - 25BaO - xDy_2O_3 Where x varied from 0 to 1.25 mol%, the prepared glass samples exhibited a yellowish transparent appearance. Characterization and Analysis: Morphological and Structural Analysis: Scanning Electron Microscopy (SEM) was used to examine the morphology of the glass samples. X-ray Diffraction (XRD) patterns confirmed the amorphous nature of all glass samples. Optical Properties: UV-Vis absorption spectra were analyzed in the 200–1100 nm wavelength range. Key optical parameters, including absorption coefficient and direct and indirect optical band gaps, were determined. Mechanical Properties: Ultrasonic wave velocity measurements were conducted at 5 MHz at room temperature to assess the mechanical behaviour of glass and glass-ceramic samples.Thermal Analysis: Differential Thermal Analysis (DTA) was performed from room temperature up to 800°C at a heating rate of 10°C/min to determine: Glass transition temperature (Tg), Onset crystallization temperature (Tx), Crystallization temperature (Tc), Melting temperature (Tm), Thermal stability range of the glass samples. Radiation Shielding Efficiency: Gamma-ray attenuation was evaluated using a sodium iodide (NaI(Tl)) detector and radioactive sources Cs-137 and Co-60. The results indicated that as the thickness of the shielding samples increased, the transmission factor decreased, leading to higher radiation protection efficiency for both glass and glass-ceramic samples.
