Brief Summary:
The purpose of this study is to compare the regenerative results of using separately two different xenografts after two-step sinus floor elevation.

Primary Outcome Measures :
  1. Uneventful healing and histological bone formation [ Time Frame: 6 months following sinus floor augmentation ]

Secondary Outcome Measures :
  1. X-ray demonstration of volume - stable results [ Time Frame: 6 months following augmentation procedures. ]
  2. Equally high implant survival rates and crestal bone loss [ Time Frame: After 1,2 years ]
