Study Arms (2)

zirconia barrier

ACTIVE COMPARATOR

Zirconia will be used as a barrier material because it has interesting features and, if compared to titanium, it induces a better fibroblast response. It also shows less biofilm adhesion and less inflammatory response. From the pre-operative CBCT a 3D model of the alveolar jaw bone will be created. A 0.4-0.5 mm-thick barrier will then be designed. It will be designed to cover the planned bone graft and extended a few millimeters wider than the graft perimeter.

Procedure: zirconia barrier

titanium mesh

PLACEBO COMPARATOR

Titanium mesh in particular, its clinical suitability for GBR procedures is unmatched by other GBR membranes, due to their exceptional volume stability, titanium meshes are indispensable in the management of vertical or large horizontal bone defects. Titanium meshes not only demonstrate high strength and stiffness but also exhibit good plasticity, allowing them to be perfectly adapted to various bone defects through bending and shaping. Due to titanium mesh's stiffness and sharp edges from cutting and bending, mucosal flaps may be adversely stimulated, leading to mucosal rupture and subsequent mesh exposure

Procedure: titanium mesh
