Primary Outcome Measures:
  • increase in bone height [ Time Frame: 9 months ] [ Designated as safety issue: No ]
    Baseline and 9 months radiographs were scanned with an Agfa scanner at 1200 dpi with a 12-bit grayscale and stored in JPEG format. Changes in bone height were calculated in each case. Two reference points, one at the lowest part of the ridge crest and the other at the highest part of sinus floor, were selected in two radiographs (baseline and after 9 months) and their distance was calculated in 0.1mm scale using computer.


Secondary Outcome Measures:
  • Bone Density [ Time Frame: 9 months ] [ Designated as safety issue: No ]
    Changes in radiographic density after sinus grafting were evaluated using densitometry.

Arms Assigned Interventions
Active Comparator: Open Sinus Lift with DFDBA
In each patient, one sinus was chosen at random and filled with DFDBA (Tissue Regeneration Corporation, Iran).
 Procedure: Open Sinus Lift

A crestal incision was made on the mucosa of the edentulous ridge. The flap was elevated carefully and extended labially to expose the bone. A vertical releasing incision was made in the mesial end of the flap as needed. The mucoperiosteal flap was extended to expose the alveolar ridge and the lateral wall of the maxillary sinus. Then, a window was prepared using the piezoelectric device (Mectron, Italy); the Schneiderian membrane was then elevated conservatively according to the technique described by Vercellotti (2001).

The sinus membrane was meticulously detached and pushed superiorly to allow for the placement of bone graft material.
Experimental: Open Sinus Lift with Algipore
The contra lateral sinus was filled with Algipore (Dentsply, USA).
 Procedure: Open Sinus Lift

A crestal incision was made on the mucosa of the edentulous ridge. The flap was elevated carefully and extended labially to expose the bone. A vertical releasing incision was made in the mesial end of the flap as needed. The mucoperiosteal flap was extended to expose the alveolar ridge and the lateral wall of the maxillary sinus. Then, a window was prepared using the piezoelectric device (Mectron, Italy); the Schneiderian membrane was then elevated conservatively according to the technique described by Vercellotti (2001).

The sinus membrane was meticulously detached and pushed superiorly to allow for the placement of bone graft material.

Detailed Description:

Vertical and horizontal bone resorption of the alveolar ridge are common in edentulous jaws. In the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities to crestal bone. Sinus floor augmentation is an established way of increasing the height and volume of bone in the posterior region of the maxilla, which increase the stability of dental implants. For this purpose various materials, including auto grafts, allografts, alloplasts, and xenografts have been used.
