N2  - Aim: Is to compare the stress distribution pattern in two different attachment systems namely: Bar\clip. And Ball\socket. In implant supported overdenture at different zones in bone surrounding dental implant with application of force with different magnitudes and directions using 3D Finite element analysis. Material & Methods: 3d model of two edentulous maxilla restored with implant supported overdenture using different attachment designs. Amount of 50, 100 and 150 N load in deferent directions (vertical and oblique) were applied through the overdenture simultaneously on posterior dentition by aid of finite element analyses software. Loads were directed toward the central fossa. Stress analysis was carried out to detect the generated stresses on bone surrounding dental implants. Results: When comparing between both attachments, the maximum Von Mises stresses in vertical loads of 50, 100, and 150 N and both 50 N oblique loads. Ball attachment shows lower stress levels at the cancellous as well as cortical bone surrounding dental implants
