5. Assistant Professor Kahtan Adnan Hamad as an adviser.

Abstract
The aim of this study is to improve and develop the poly (methyl methacrylate) (PMMA) as acrylic resin material, which are commonly used for manufacturing of
partial and complete denture base material. This could be achieved by the addition of a new natural powders to produce PMMA composite material, the (PMMA) resin strengthening by addition two types of natural powders (Peanut and Walnut Shells) powders to enhance its properties and resist any reasons of cracks which lead to the finally fracture of denture base. These reinforcing powders added with a similar particle size and different weight fractions. Therefore, this work showed the efficiency of adding these powders on mechanical and physical properties of PMMA composite denture base material samples. Furthermore, this work finished by performing several mechanical and physical tests such as (tensile, impact, flexural, compression, hardness, surface roughness, density and water absorption) tests. In addition to other tests, morphological test such as scanning electron microscopy (SEM), and miscibility tests such as (differential scanning calorimeter (DSC) and Fourier transform infrared spectroscopy (FTIR)).

Congratulations to the student on her graduation.
