Posterior maxillary implant with sinus lifting is technique sensitive. Opting a precise procedure within the clinical constraints will eventually payoff. The purpose of this systematic review is to analyse a specific procedure based on notable clinical parameters apt to an individual subject. A Systematic search on PubMed databases with the MeSH terms “sinus lift, bone gain, trans-crestal, lateral “was performed. Articles were critically reviewed by the examiners basing on inclusion criteria. Letters to the editor, case reports, commentaries, and articles published in languages other than English were excluded. A total of 969 articles presenting various studies conducted in maxillary posterior region with respect to sinus lift were evident. Out of which 21 prospective studies were considered relating to the procedural and background parameters included in the study. The parameters considered were the residual bone height, type of approach and the endo sinus bone gain following a prescribed interval. Due to heterogeneity across all the studies, meta-analysis was not performed. Within the limitations of the study, the results revealed that the selection of type of approach depends on the pre residual bone height. In order to obtain maximum bone, gain lateral approach is to be preferred to other two approaches.
