Abstract

Purpose: A novel autogenous block bone grafting technique with simultaneous placement of dental implants is described for several cases of horizontal ridge augmentation. Methods: Seven patients with a mandibular horizontal ridge that was inadequate for proper implant placement were included in this study. Simultaneous implant placement and autogenous block bone grafting was planned; we designed the "L-shaped notch" preparation of the recipient site for the additional fixation with only 1 screw. This new technique also required minimal size of autogenous block bone. Results: In total, 11 implants and final restorations were delivered in 7 patients. The dehiscence defects were covered successfully (79.70 6 5.58%; 2.26 6 0.68 mm) at the uncover surgery. The marginal bone loss was 0.50 6 0.26 mm on the mesial side and 0.58 6 0.23 mm on the distal side. The outcomes were satisfactory clinically and radiographically during the 1-year follow-up. Conclusion: Although additional studies, with more than 7 patients, are needed to evaluate the L-shaped notch preparation, this was effective to accomplish horizontal ridge augmentation simultaneously with the placement of dental implants using the minimal size of autogenous block bone.
