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.

Conditions

• Disorder of Maxillary Sinus
• Maxillary Sinus Floor Augmentation

Interventions

Type	Name	Description
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.
