Abstract

Surgical placement of oral implants is governed by the prosthetic design and by the morphology and quality of the alveolar bone. Nevertheless implant placement often appears difficult, if at all possible, due to aberrations of the alveolar ridge. Hence prosthetically dictated implant positioning often entails augmentation of the alveolar ridge and adjoining structures. In this review we discuss recent observations of the biologic potential, clinical relevance, and perspectives of application of recombinant human bone morphogenetic protein-2 (rhBMP-2) technologies for alveolar bone augmentation and oral implant osseointegration. Using discriminating critical-size supraalveolar defects and clinical modeling in dogs, we show that rhBMP-2 has a substantial potential for augmenting alveolar bone and supporting osseointegration of titanium oral implants. Moreover, using clinical modeling, we demonstrate re-osseointegration in advanced periimplantitis defects and long-term functional loading of titanium oral implants placed into rhBMP-2-induced bone. Our studies suggest that inclusion of rhBMP-2 for alveolar bone augmentation and oral implant fixation will not only enhance the predictability of existing clinical protocol but also allow new approaches to these procedures.
