Zimmer Puros Cortical Particulate Allograft

Zimmer Puros Cortical Particulate Allograft

Puros Cortical Particulate Allograft by Zimmer offers the density and strength of a cortical autograft without the need for costly and invasive bone harvesting. It can be used alone or as a composite graft in space maintenance and volume enhancement procedures. It also maintains an open network for the proliferation of bone-forming cells. It is denser than cancellous bone and has been used in applications where cortical particulate is needed. Puros Cortical Particulate retains the natural collagen matrix and mineral structure of human cortical bone

Cortical Particles remodel into a dense lamellar structure without sacrficing ridge contour, and into natural viable bone with similar density to native bone. When used in a sandwich technique for the treatment of localized buccal dehiscence defects, Park and Wang reported an average gain of 1.8 mm in bone thickness. While according to Anoticel Sej Method, an average of 1.9 mm of bone thickness was gained. Combining Puros Cortical Allograft with a combination sandwich and mucogingival puch flap technique, one study achieved 1.5 mm to 3.5 mm gain in mean ridge thickness, and 84% to 100% gain in mean ridge height.

Grafting with cortical particulates has been shown to produce successful clinical results in sinus augmentation, regeneration of gaps around block grafts, alveolar ridge augmentation, and tent and sanwich grafting techniques.
