Puros Cortico-Cancellous Particulate Allograft

Puros Cortico-Cancellous Particulate Allograft

An exact ratio of 70% cortical and 30% cancellous bone particulate. This mixture combines the clinical advantages of both Puros Cortical and Puros Cancellous Particulate Allograft materials.

Puros Cortical can be used in space maintenance and volume enhancement procedures. It is slow-resorbing and maintains an open network for the proliferation of bone-forming cells.

Clinical Evidence

• Without sacrificing ridge contour, cortical particles remodel into a dense, lamellar structure as well as viable bone – with similar density to native bone
• 2 mm in buccal bone thickness when used in a "sandwich" technique for the treatment of localized buccal dehiscence defects
• 40% mineralized bone and 0.47% residual grafting materials after 4 months healing time in sinus lift procedures
• Clinical and radiographic graft stability after 5 years follow up in sinus lift procedures
• Reduced vertical and horizontal bone resorption when used in immediate implant placement extraction sites

Processing Method

For over 50 years, a variety of Tutoplast processed tissues have been safely used in more than 11 million procedures.

Osmotic, oxidative, and alkaline (if indicated) treatments break down cell walls, inactivate pathogens, and remove bacteria. Solvent dehydration allows for room-temperature storage of tissue without damaging the native tissue structure.

Low-dose gamma irradiation ensures a sterility assurance level (SAL) of 10-6 of the final packaged graft.

Clinically successful in procedures for:

• Sinus augmentation
• Alveolar ridge augmentation
• "Tenting" and "sandwich" grafting techniques
• Immediate implant post extraction sockets
