Aim: To accomplish a comparative study between two types of attachment Equator and Ball/Socket in mandibular implant supported overdenture by using finite element analysis and assessment of stress distribution on the bone, implant. overdenture, mucosa and attachment.
Methodology: Three-dimensional models simulated a clinical situation where an edentulous mandible was restored by two different treatment options using implant overdentures. The overdentures were supported by two implants placed at the approximate canine region using Ball/Socket and Equator attachments. The load was applied of value of 50,100,200 N with angle of vertical 90° then the oblique load with angel 45°.
Results: Attachment total deformation with using ball and socket attachments deforms much more than using equator attachment. Similarly, attachments Von Mises stress increase dramatically with ball and socket attachment. Central incisor loading did not show as much difference as molar area loading.
Conclusion: Equators body and its caps (flexible and metallic) received lower stresses that indicating longer life time and longer periods between successive maintenances.
