Advanced Alveolar Bone Resorption Treated With Implants, Guided Bone Regeneration, and Synthetic Grafting: A Case Report

Purpose: To present a vertical ridge augmentation with a composite synthetic bone graft by the mixed bone-filling materials and autogenous bone chips retrieved from the implant osteotomy site for a case for esthetic implant prosthesis on the atrophied alveolar bone. Materials: Nonresorbable and resorbable hydroxyapatite and demineralized freeze-dried bone allograft particles were used at ratio of 1:2:2 (volume ratio). Titanium micromesh was used for alveolar ridge configuration and retention. After 8 months, implant placement and interimplant bone augmentation were performed. Results: 15-mm vertical and 10-mm horizontal bone augmentation has been achieved. Marginal bone heights and periimplant mucosa remained stable in cases of loading after >4 years of follow-up. Conclusion: These results suggest that this method has the potential for use in esthetic implant rehabilitation on the highly atrophied alveolar bone. (Implant Dent 2010;19:460-467)
