Regraft of Incomplete Sinus Bone Graft Incorporation: Use of rhBMP-2
This is a 52 year old female physician who had a left maxillary sinus graft done 5 months previously. Follow up evaluation revealed complete sinus bone graft incorporation (Figures 1,2).
Treatment now included debridement of the sinus to remove all loose bone graft fragments (Figures 3,4,5).
In addition, a type 1 collagen membrane (Memlok) was then used with external tack fixation (Pikos technique), followed by sinus regraft that included the use of rhBMP-2, mineralized allograft and xenograft (Figures 6,7).
Two BioHorizons tapered internal implants were then placed in a nonsumberged mode (Figures 8,9).
Follow up at two years revealed clinical and radiographic evidence of stable soft and hard tissue (Figures 10,11).
