Transalveolar sinus floor lift without bone grafting in atrophic maxilla: A meta-analysis

Abstract We performed a meta-analysis aimed to assess the clinical results after transalveolar sinus floor lift without bone grafting in the atrophic maxilla. A systematic electronic literature search was conducted in PubMed, Embase and The Cochrane Library, followed by a manual search. Two reviewer...
