Purpose: This study set out to assess the efficacy of augmentation of the posterior atrophic mandibular ridge utilizing a 3D-model with pre-adapted titanium mesh, bovine bone graft, and platelet-rich fibrin. Patients and methods: A study was carried out on eight (8) patients who had posterior atrophic ridge. The patients were given a pre-adapted titanium mesh that had bovine bone graft and platelet-rich fibrin. After the Ti-mesh was removed, the implants were installed simultaneously, and finally, the final restoration was inserted. Clinical and radiographic assessment of the stability of the graft and implant.
