Objective: The objective of the present study was to evaluate the efficiency of the alveolar ridge reconstruction with titanium mesh and a mixture of autogenous bone graft and bone substitutes (Algipore) in the atrophic mandible. 
Subjects and Methods: Clinical examination was made to all patients. Preoperative panoramic radiographs and cone beam CT were taken for every patient to determine alveolar bone height& width. The change in the implant stability and bone density was measured using cone beam computerized tomography (CBCT) immediately, and after 3, 6 months of healing. All readings were recorded and analyzed statistically. Results: The mean horizontal bone gain was 3.4±2.0mm &the mean vertical bone gain was 5.4±3.4mm after 6 months follow up, which was statistically significant.Conclusion: Excellent bone augmentation results both vertically and horizontally except for those of titanium mesh exposure.
