Sinus mucosa elevation using Bio‐Oss^® or Gingistat^® collagen sponge: an experimental study in rabbits

Abstract

New bone was found forming from the pristine bony walls of the sinus and extending toward the most peripheral regions in both sites. While DBBM particles yielded osteoconductivity and were able to preserve over time the space within the elevated mucosa, the collagen sponge failed the goal of maintaining the space.
