Different Techniques of Crestal Sinus Lift

Study Overview
=================
Brief Summary
-----------------
Sixteen patients will be selected from those attending the outpatient clinic of the Oral & Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University with age range from 20-50 years seeking implantation of their lost posterior maxillary teeth, [premolar and molars] with limited bone height below the floor of the maxillary sinus, secondary to sinus pneumatization. Group I (N = 8): The sinus membrane will be elevated by using balloon technique with simultaneous Implant placement. Group II (N = 8): The sinus membrane will be elevated by using Densah burs with simultaneous Implant placement.
