Abstract:
The study aimed to prepare a composite material containing different weight ratios of magnesium for use in the treatment of maxillary bone decay. A ceramic material with improved mechanical properties consisting of 70 wt.% hydroxyapatite and 30 wt.% cordierite ceramic is manufactured, sintered at 1100°C and then used as a reinforcement phase within a polycaprolactone matrix. Magnesium was added in proportions of 1, 3, 5, 7 wt.% to the composite material for the purpose of evaluating the effect of magnesium on biological performance in vivo and in vitro. The results proved that the presence of magnesium element by 5 wt.% led to an improvement in all biological properties in terms of degradation rate, bioactivity, cell viability, cell attachment in addition to the formation of new bone after 45 days of transplantation, and this is proven by the results of the histological analysis of the bone sample.
After the discussion committee recorded its observations on the thesis, which were divided between explanation, correction, and the student’s defense of her thesis.
At the end of the discussion, the committee decided to evaluate the thesis and decided to grant the student a doctorate degree with a pass grade.
