The purpose of this study was to clinically, histologically, and immunohistochemically evaluate the quantity and quality of newly regenerated bone by means of direct clinical measuring and biopsy specimens of alveolar ridges augmented by autogenous cortical bone or titanium micromesh—both filled with autogenous particulate bone graft in the anterior jaws. For the preliminary study, 10 alveolar bone defects in five partially edentulous patients (two men and three women), between 19 and 35 years old (mean: 25.4, SD: 5.94) were selected. Bone defects were randomly (coin toss) divided into two groups: A (micromesh) and B (bone block). The donor site was the mandibular symphysis in all cases. On the return appointment, operative grafts appeared well incorporated into the native bone, which suggests that good contact and fit between the graft and the recipient site had been obtained during the first surgery. Histologic investigations confirmed excellent integration and revascularization of the graft in both study groups, with formation of new bone tissue without any relevant inflammation.
