Three-Dimensional Bone Augmentation of Severely Atrophied Posterior Mandibular Alveolar Ridges Using Customized-3D Zirconia Barriers Versus Pre-bent Titanium Mesh

Zirconia can be considered as an alternative and innovative material suitable for GBR because it has high biocompatibility, together with a scarce tissue integration. Zirconia barriers could be a predictable and alternative barrier material for GBR in terms of (i) biocompatibility, (ii) ease of use and removal, (iii) exposure management, (iv) bone regeneration outcomes.
