Possible Applications for a Biodegradable Magnesium Membrane in Alveolar Ridge Augmentation–Retrospective Case Report with Two Years of Follow-Up

Background and Objectives: A rigid, resorbable magnesium membrane was recently developed, combining the advantages of non-resorbable membranes. Our aim to describe application this for guided bone regeneration (GBR). Materials Methods: This case report described treatment 3D evaluation two cases utilizing a barrier membrane. In Case #1, GBR performed with bilayer tunnel flap. The placed fixed subperiosteally through remote vertical incisions. #2, using split-thickness flap design. Volumetric linear hard tissue alterations were assessed by cone-beam computed tomography subtraction analysis, as well conventional intraoral radiography. Results: #1 showed volumetric gain 0.12 cm3, whereas #2 presented 0.36 cm3 gain. No marginal peri-implant loss could be detected at two-year follow-up. Conclusions: collagen membranes would difficult in either presented. However, rigid structure allowed limitations overcome.
