Clinical investigation of rhBMP-2 and simultaneous dental implants placement: Preliminary results

Background. Rebuilding atrophied alveolar ridges can present a significant challenge. There is a multitude of treatment options including guided bone regeneration, onlay block grafting, and distraction osteogenesis. Positioning of dental implants can be placed in an immediate or delayed fashion. An advantage of placing implants immediately is that the patient’s treatment course is shortened as well as the potential for maintaining soft tissue is present. Methods. The recent FDA approval of recombinant human bone morphogenic protein (rhBMP-2) has given clinicians an added treatment option for reconstructing localized alveolar defects. Several patients have been treated with dental implant and rhBMP-2 and the results were recorded by clinical and radiological exams. Results. The potential to reconstruct these challenging defects with a growth factor thus limiting or even avoiding a secondary harvest site is exciting. We describe our experience with the use of implants and bone morphogenic protein together. This study presents excellent results about the combination of using dental implants and growth factor for treating substantial bone defects. Conclusion. Our goal was to clinically evaluate the potential of a purpose designed titanium porous-oxide dental implant surface combined with rhBMP-2
