The presented case report highlights the application of NOVAMag® membrane for treating a complex defect with horizontal and vertical components. Following tooth extraction, the defect space was augmented with cerabone® and covered with the resorbable magnesium membrane to support and maintain space for the graft. Eventually, the whole augmentation site was covered with Jason® membrane and the flap was sutured for primary healing. During the follow-up period, there were no complications with the soft tissue. At 8 months, the re-entry was performed revealing good quality and quantity of bone with no remnants of the magnesium membrane. The edentulous area was successfully restored with an implant-supported bridge.

BACKGROUND AND OBJECTS

In guided bone regeneration (GBR), large defects comprising both horizontal and vertical components usually require additional mechanical support to stabilize the augmentation and preserve the bone volume. This additional support is usually attained by using non-resorbable materials. A recently developed magnesium membrane (NOVAMag® membrane) presents the possibility of providing mechanical support whilst being completely resorbable. The aim of this case report was to describe the application and outcome of the magnesium membrane in combination with a collagen pericardium membrane (Jason® membrane) for GBR.

MATERIALS AND METHODS

A 74 year old, in an otherwise good general health condition, was presented with stage 2 grade A periodontitis and an impacted canine. After extraction of the impacted canine, a defect was created with both vertical and horizontal components. The defect was augmented NOVAMag® membrane to create a supportive arch to the underlying bone graft and Jason® membrane was placed on top to aid with the soft tissue closure.

CONCLUSION

In this case, the NOVAMag® membrane in combination with Jason® membrane presented a potentially viable alternative treatment to titanium meshes or titanium-reinforced membranes for the augmentation of a defect with both horizontal and vertical components that is completely resorbable. It was demonstrated that it is possible to attain a good quality and quantity of bone using a resorbable system that has been completely resorbed by the time of reentry.
