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

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 periiniplant mucosa remained stable in cases of loading after >4 years offollow-up. Conclusion: These results suggest that this method has the potential for use in esthetic implant rehabilitation on the highly atrophied alveolar bone. [ABSTRACT FROM AUTHOR]
