Four 3D finite element models were created simulating clinical situation where an edentulous mandible was restored by four different treatment options using implant overdentures. The overdentures were supported by either two implants placed at the approximate canine region or four implants; two at the approximate canine region and other two implants at second premolar region using ball and locator attachments. The models{u2019} components were created on commercial CAD/CAM package then imported to Finite Element Software. UR - http://172.23.153.220/th.pdf ER -
