Guided Bone Regeneration (GBR) with custom titanium meshes represents a paradigm shift from freehand bone grafting. Digital design from CBCT data allows the mesh to precisely define the desired bone volume, shape, and contour before surgery.
Digital GBR Protocol
1. CBCT acquisition: High-resolution CBCT of the defect site
2. Virtual bone segmentation: The desired bone volume is designed digitally, accounting for implant positions
3. Mesh design: Titanium mesh is designed to fit the alveolar ridge contour with 1-2mm offset for graft material
4. Fixation planning: Screw holes are positioned to avoid vital structures and provide stable fixation
5. Manufacturing: Titanium mesh is 3D-printed or milled, then sterilized for surgical use
Clinical Advantages
- Predictable graft volume (deviation less than 1mm from planned volume)
- Reduced surgical time (mesh fits perfectly, no intraoperative bending)
- Better soft tissue adaptation (smooth mesh contours)
