N2  - The implant supported overdenture for complete edentulous patients become more satisfied for patients in retention, phonetics and mastication when compare to conventional denture . The literature regard the more occlusal force transmitted to implants and surrounding structure lead to bone resorption (Kim et al. 2004b; Wang et al. 2017). The aim of this study compare between different types of denture base materials that help in decrease bone resorption and less overdenture maintenance , the amount of force using by finite element analysis . When compare between forces application vertically on mesial first molar and distal of second premolar area by forced 50N, 100N.150N and oblique 100 N  the (worst scenario) , in both conventional acrylic resin and flexi resin acrylic both in physiological limit of bone . Within limitation of study following conclusion can be derived :  1)Cortical bone showed similar outcome in both denture base materials. 2)Cancellous bone behavior showed no effect of denture base material on its stresses or deformations . 3)Rigid denture base material generated higher stresses on magnetic attachment by about 10% than using the resilient one
