Introduction: Pay attention to Acrilie Reinforced Denture is important for dentists especially in elder persons that have less control on them. Objective: The aim of this study is comparison of transverse strength in PMMA rein forced by Wire and Iron Mesh. Materials and Methods: In this research thirty hard, heat curing acrylic in dimensions of 31570 mm which was selected in ten samples for each Parameter. The selected groups were reinforced with putting 1/00 mm Wire (Group 02) and Mesh (Group 03). Every Single Sample was constructed and generated, even the control group, Which was without any sort of reinforce processing was tested using an Instron device where its strength was thoroughly evaluated. The outcome of the following experiments illustrated the fact that using Wire 1.00 mm increases the strength whereas using the Mesh decreases such strength this experiment proved this fact to the point. Furthermore, when samples where tested through using Wire 1.00 mm, the transverse strength increased up to twelve percent, which shows the fact that the acrylic could be generated even without increasing the volume or the dimensions. Therefore, there will less chance of denture to break down if a thicker wire is used. (1.00 mm Wire) This is carried out on aged patients who are mostly unable to take care of their own denture and use this process to increase the stability in the areas where most of the pressure and use stress is focused on, in which the risk decreases to about twelve percent.
