Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Open Sinus Lift with DFDBA

In each patient, one sinus was chosen at random and filled with DFDBA (Tissue Regeneration Corporation, Iran).

Group Type ACTIVE_COMPARATOR

Open Sinus Lift

Intervention Type PROCEDURE

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.

Open Sinus Lift with Algipore

The contra lateral sinus was filled with Algipore (Dentsply, USA).

Group Type EXPERIMENTAL

Intervention Type PROCEDURE

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.
