About this study
Official title: Comparative Study of Algipore and Decalcified Freeze-dried Bone Allograft in Open Maxillary Sinus Elevation Using Piezoelectric Surgery
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Open Sinus LiftProcedure or surgery
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.
| Study group | Role | What they receive |
|---|---|---|
| Open Sinus Lift with DFDBA | Active comparator | In each patient, one sinus was chosen at random and filled with DFDBA (Tissue Regeneration Corporation, Iran). Receives: Procedure: Open Sinus Lift |
| Open Sinus Lift with Algipore | Experimental | The contra lateral sinus was filled with Algipore (Dentsply, USA). Receives: Procedure: Open Sinus Lift |
What is being measured
The primary outcome is the main question the study is designed to answer.
increase in bone height
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.
Measured: 9 months
Secondary outcomes (1)
Bone Density
Changes in radiographic density after sinus grafting were evaluated using densitometry.
Measured: 9 months

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Open Sinus Lift in people with Disorder of Maxillary Sinus and Maxillary Sinus Floor Augmentation, run by Mashhad University of Medical Sciences at 1 site in Iran.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
increase in bone height (time frame: 9 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2015; AzTrials last refreshed its copy on 7 Nov 2026.
