While, study group undergo for graftless sinus lift using AMBE through small antrostomy with simultaneous implant placement. the aim of the study is assessment the effect of antrostomy size on bone formation in graftless sinus lift with simultaneous implant placement.\n\nCBCT will be done before and after the surgery and after 6 months to assess of amount bone gain in mm.\n\nimplant stability after 6 months will be determined by using Osstell.
