VERTICAL AUGMENTATION OF THE ALVEOLAR RIDGE BY THE TECHNIQUE OF GUIDED BONE REGENERATION USING A RESORBABLE MAGNESIUM MEMBRANE: A CASE REPORT

Case presentation: Lack of bone volume either vertically or horizontally may prevent prosthetically guided implant placement. Guided bone regeneration is the best documented surgical technique in the literature for alveolar bone regeneration. Membranes developed for this technique can be divided into two groups: resorptive and non-resorptive. The magnesium-based membrane (NOVAMag®) is a new resorptive membrane that has improved properties compared to most other resorptives: excellent mechanical properties and a reduced possibility of the membrane collapsing within the bone defect. After completing orthodontic therapy, the patient comes to the office to compensate for the loss of a frontal tooth in the maxilla. Analysis of CBCT revealed a lack of bone in horizontal and vertical dimensions. The bone defect was regenerated using magnesiumbased resorptive membrane (NOVAMag®) and a composite bone graft consisting of a majority of autologous bone and a smaller percentage of xenogeneic bone. The membrane was fixed with magnesium-based resorptive screws (NOVAMag® fixation screw). In order to achieve an optimal soft tissue profile, xenogenic collagen matrix (mucoderm®) was placed over the membrane. The flap was sewn in two layers. Clinically, after f ive months of healing at the augmentation site, a satisfactory volume of bone and soft tissue was achieved, and control CBCT confirmed the regeneration of the labial and palatal cortex of the alveolar ridge. Conclusion: This case report describes the use of new magnesium-based resorptive membrane for vertical augmentation of alveolar ridge. After five months of healing, bone regeneration at the augmentation site was confirmed clinically and radiologically.
