This presentation discusses the use of a solvent-preserved, mineralized human cancellous bone allograft (ie, Puros) with or without collagen membrane for periodontal regeneration. The unique properties of this material will be thoroughly considered. Data from recent controlled human clinical trials using this bone graft and collagen membrane for periodontal regeneration (eg, infrabony and furcation defects) will be presented. A step-by-step technique of material use in various clinical situations will be demonstrated. Advantages and limitations of these materials will also be discussed.
