Manuscript Info Abstract ……………………. ……………………………………………………………… Manuscript History Received: 06 June 2017 Final Accepted: 08 July 2017 Published: August 2017 Key words:- Ridge splitting, Expansion, Guided bone regeneration. Background: Several modifications have been applied to the ridge splitting with or without expansion technique to allow for implant placement in the atrophic ridges. Some studies utilized guided bone regeneration and others not. Aim: This systematic review will try to present the different studies discussing the effects of conjunction of bone grafting materials and/or membranes or not with the ridge splitting with or without expansion for patients having insufficient bucco-palatal ridge width. Methods: A thorough PUBMED (Medline) and COCHRANE databases search in addition to hand-search of journals of relevance was performed on related terms in the period from 1992 to 2016 and resulted in 3247 titles of which 21 abstracts were selected and collected as full articles for further evaluation while the rest were excluded by title or abstract. According to the inclusion criteria 14 studies were included and discussed in this article. Results: Of the 14 studies included in the present study only one study (cohort- retrospective) compared ridge splitting with/without expansion technique alone and with guided bone regeneration. Twelve studies applied guided bone regeneration while three studies did not. Copy Right, IJAR, 2017,. All rights reserved. ……………………………………………………………………………………………………....
