Study Design: The three major electronic databases were screened: MEDLINE (via PubMed), and SCOPUS and ELSEVIER Review: Methodological quality assessment showed sample size calculation to be reported by only one study, and follow-up did not include a large number of participants - a fact that may introduce bias and lead to misleading interpretations of the study results. Conclusions: A systematic review of the current literature showed only in vitro evidence that there is no consensus on the advantage of using an offset configuration implant compared to those in straight-line configuration, well some studies shown significant improvement of bone stress distribution when an angulated implant is under oblique loading. Keywords: Dental implants, implant-retained dental Prosthesis, prosthodontics, biomechanics. INTRODUCTION Implant supported prosthesis has become a routine dental treatment. To achieve the best outcome, careful consideration of technical and biomechanical parameters, is essential [1]. The rehabilitation of the posterior region of the jaw is complex, mainly due to greater masticatory forces when compared with the anterior region. In this region, implants used to retain the three-element prostheses are normally placed in a straight line. . It has been reported that the role of implant length is more significant in reducing bone stress and improving the implant- abutment stability in comparison with implant diameter. [2,3] Nevertheless, a small displacement of the central implant to the buccal or lingual area has been suggested, featuring an offset configuration, whose purpose, theoretically, is a stress distribution more favorable to prosthetic components, implant, and bone.
