Dr. G asks:
I have been using Puros Allograft, from Zimmer Dental, for soft tissue augmentation. I’ve had mixed results and I would like to switch to Alloderm, from Lifecell, but I have not been able to find peer-reviewed articles establishing the efficacy of using Alloderm for dental implant placement. Do you have any experience with Alloderm with implant placement? How does it compare to Puros?
“The Puros family of bone grafting products provides an effective and predictable clinical outcome for patients requiring bony enhancement of the mandible and maxilla in a timely manner. The patented Tutoplast® process gently removes unwanted material such as fats, cells, antigens, and inactivates pathogens, while preserving the valuable minerals and collagen matrix, leading to complete and rapid bone regeneration. Puros allografts are used in clinical situations where a human allograft is appropriate, such as dental bone grafting procedures, sinus grafting or in conjunction with dental implant procedures. ” More at ZimmerDental.com
“AlloDerm is an acellular dermal matrix derived from donated human skin tissue supplied by US AATB-compliant tissue banks… Since AlloDerm is regarded as minimally processed and not significantly changed in structure from the natural material, the FDA has classified it as banked human tissue. When AlloDerm is prepared, the human donor tissue undergoes a multi-step proprietary process that removes both the epidermis and the cells that can lead to tissue rejection and graft failure, without damaging the matrix…The processed tissue matrix is preserved with a patented freeze-drying process that prevents damaging ice crystals from forming. ” More at LifeCell.com
