13. AIM OF THE STUDY •  The present study aims at using a precise three dimensional finite element analysis to evaluate stress distribution around integrated dental implants with mandibular implant-retained-overdenture.

14. AIM OF THE STUDY • The first implant-supported-overdenture will have ball and socket abutment configuration, while the other will have locator abutment configuration.
