Abstract
The purpose of the study is to evaluate the osteogenic potential of the maxillary sinus in a two-stage sinus membrane elevation using titanium mesh to maintain the created space after membrane elevation without the use of any graft or space-filling material for future site development for the placement of dental implants in severely atrophied posterior maxillary ridge
