Purpose: To present a retrospective report of eight significant alveolar defects in which the
alveolus was regenerated with recombinant human bone morphogenetic protein 2 (rhBMP-2)
combined with anorganic bovine bone and contoured using titanium mesh to facilitate implantsupported
restorations. Materials and Methods: A total of seven patients underwent extractions
and debridement of the compromised alveolar sites with simultaneous grafting using a mixture
of rhBMP-2 and anorganic bovine bone. The three-dimensional contour of the compromised
alveolus was reestablished using titanium mesh with rigid screw fixation. Implants were placed
a minimum of 6 months after healing and subsequently were restored. Results: The treated
defects were successfully regenerated and did not require any additional surgery prior to implant
placement or prosthetic restoration. A total of 14 implants were placed and restored with fixed
single or multiple restorations. Thirteen of the 23 treated sites were in the anterior esthetic zone.
Conclusion: Vertical and horizontal alveolar bone defects can be predictably regenerated by
grafting with a combination of rhBMP-2 and anorganic bovine bone contained by titanium mesh
to successfully accommodate implant placement. Oral Craniofac Tissue Eng 2012;2:207–214 Key words: bone grafting, bone regeneration, rhBMP-2, titanium mesh
