[Clinical effects of ridge augmentation with the half-columnar shaped mandibular bone block for the placement of dental implants].

The half-columnar shaped mandibular bone graft (from the ramus and external oblique ridge) is a promising technique for bone augmentation in localized alveolar ridge defects after single tooth missing. This procedure offers easy access, good bone quantity for localized repair, low morbidity, decreased complaints of postoperative sensory disturbances or discomfort, minimal graft resorption, and a shorter healing time as compared with other methods for bone repair.
