---------------------------------------------------------------------***--------------------------------------------------------------------BACKGROUND: The platform switching concept involves the reduction of the restoration abutment diameter with respect to diameter of dental implant. Long –term follow up around these wideplatforms showed higher level of bone preservation and proper stress distribution and esthetic look. AIM: The aim of this paper is to carry out literature review of studies which deal with the influence of platform-switched implants in hard and soft tissue with Finite element method and stress distribution pattern observed in different implant systems. MATERIALS AND METHOD: All papers involving Dental implants, Platform-switching, Finite element analysis and combination of these words where used and papers from science direct, ELSEVIER, Pub Med were analyzed and reviewed. RESULTS: In our search most of papers result outcome indicate that in platform-switching peri-implant bone resorption is reduced and showed better stress distribution around bone than conventional implants system. CONCLUSION: All papers written by different researchers showed an improvement in peri-implant bone preservation and better stress distribution and less stress transfer to bone. However there is lack of non-linear finite element analysis which would explain real life simulation and better stressdistribution pattern and experimental methods to validate this results which are to further needed to be develop.
