Study Overview
Brief Summary
The aim of this study was the radiographic and clinical comparison of Algipore with decalcified freeze-dried bone allograft (DFDBA) in the open maxillary sinus lift technique using piezoelectric instruments.
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.

Arms & Interventions
Open Sinus Lift with DFDBA
In each patient, one sinus was chosen at random and filled with DFDBA (Tissue Regeneration Corporation, Iran).
Intervention: Open Sinus Lift (Procedure)
Open Sinus Lift with Algipore
The contra lateral sinus was filled with Algipore (Dentsply, USA).
Intervention: Open Sinus Lift (Procedure)
Outcomes
Primary Outcomes
increase in bone height
Time Frame: 9 months
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 Outcomes
- Bone Density(9 months)
