Vertical Bone Augmentation With Customized CAD/CAM Titanium Mesh for Severe Alveolar Ridge Defect in the Posterior Mandible: A Case Letter

Implant rehabilitation after implant removal is a major challenge, especially in mandibular posterior arches. This case report describes the reconstruction of a severe vertical bone defect using customized titanium mesh covered by collagen membrane and solid advanced platelet-rich fibrin, combined with autogenous bone, deproteinized bovine bone mineral, and injectable platelet-rich fibrin after implant removal caused by advanced peri-implantitis. This individualized titanium mesh may be a reliable technique for severe alveolar ridge reconstruction, with the additional benefits of reduced surgery time and a simplified operation.
