Autogenous Bone Graft for Horizontal Ridge Augmentation Associated with Simultaneous Implant Placement

Abstract

The goal of this study was to evaluate the efficacy of autogenous bone grafts with and without recombinant human bone morphogenetic protein-2 for rehabilitation of narrow alveolar ridge width by dental implants. Twelve patients (2 males and 10 females), ranging from 36 to 60 years and a mean age of 47.08 years, were divided into two study groups. One received autogenous bone graft (A1) and the other group autogenous bone graft with rhBMP-2 using a collagen membrane (A2). All patients were clinically evaluated and received a CBCT for an accurate measurement of the alveolar ridge width, height, and after six months postoperatively. The mean difference in primary and secondary alveolar bone width (after 6 months) in group A1 was 4.14 mm, with a statistically significant difference (p < 0.05). Also, the mean difference in primary and secondary (after 6 months) alveolar bone width in group A2 was 5.14 mm, with a significant difference between them (P-value 0.00). The addition of rhBMP-2 increased the extent of bone width regeneration compared with the autogenous bone graft used alone. Both study groups showed a statistically significant increase in bone width at 6 months, with the highest increase observed in group A2 (ABG + rhBMP-2).
