The aim of this study was to evaluate clinically and radiographically the efficiency of placing Trabecular Metal Material implants with bone expansion in narrow anterior maxilla. Materials and Methods: This study was performed as an experimental clinical trial, ten patients requiring implant placement in the narrow anterior maxilla of sufficient bone height and of ridge width ≥ 3mm but < 6mm were included. Bone expansion using screw-type bone expanders was performed with simultaneous placement of Trabecular Metal Material implants. The studied variables were the degree of facial swelling which was recorded and analyzed throughout base line, 4th and 7th postoperative days and the marginal bone height and bone width which were recorded and analyzed at three postoperative weeks and after three months of implants’ loading. For statistical analysis, Friedman and Wilcoxon tests were used. Results: A Significant decrease regarding marginal bone height and a significant increase regarding bone width were observed through the follow-up stage, while no significant difference was noticed concerning the degree of facial swelling when compared to base line measurements. Conclusion: The results assured the efficiency of bone expansion using screw-type bone expanders with simultaneous placement of Trabecular Metal Material implant and highlighted their promising effects concerning esthetical considerations.
