Original Title: Resorbable magnesium metal membrane for sinus lift procedures: a case series

The present study is the first to document the use of NOVAMag^® membrane in direct and indirect sinus lift procedures. NOVAMag^® membrane was applied in four clinical situations to repair ruptures or perforations of the Schneiderian membrane. A mixture of maxgraft^® granules and cerabone^® was used to fill the defects. Successful healing and satisfactory new bone formation were observed in all cases. The results of this case series demonstrate that NOVAMag^® membrane, with its unique mechanical properties while being completely resorbable, is an ideal material for separating the maxillary sinus during sinus lift procedures, particularly in cases of complete tear of the Schneiderian membrane.

BACKGROUND

The purpose of this case series was to demonstrate the use of a magnesium membrane (NOVAMag^® membrane) for repairing the perforated membrane in both direct and indirect approaches, as well as its application in instances where there has been a tear of the Schneiderian membrane.

CASE PRESENTATION

The case series included four individual cases, each demonstrating the application of NOVAMag^® membrane followed by bone augmentation using a mixture of cerabone^® and maxgraft^® in the sinus cavity. In the first three cases, rupture of Schneiderian membrane occurred as a result of tooth extraction, positioning of the dental implant, or as a complication during the procedure. In the fourth case, Schneiderian membrane was perforated as a result of the need to aspirate a polyp in the maxillary sinus. In case one, 10 mm of newly formed bone is visible four months after graft placement. Other cases showed between 15 and 20 mm of newly formed alveolar bone. No residual of NOVAMag^® membrane was seen on clinical inspection. The vertical and horizontal augmentations proved stable and the dental implants were placed in the previously grafted sites.

CONCLUSION

Within the limitations of this case series, postoperative clinical examination, and panoramic and CBCT images demonstrated that resorbable NOVAMag^® membrane is a viable material for sinus lift and Schneiderian membrane repair. The case series showed successful healing and formation of new alveolar bone with separation of the oral cavity and maxillary sinus in four patients.
