Advanced alveolar bone resorption treated with implants, guided bone regeneration, and synthetic grafting: a case report.
OBJECTIVE
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.


METHODS
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.


CONCLUSIONS
These results suggest that this method has the potential for use in esthetic implant rehabilitation on the highly atrophied alveolar bone.
