Lateral Ridge Augmentation Using an Equine Flex Bone Block Infused with Recombinant Human Platelet-Derived Growth Factor BB: A Clinical and Histologic Study.

摘要

This paper reports on a patient who underwent horizontal ridge augmentation using recombinant human platelet-derived growth factor BB (rhPDGF-BB) in combination with a collagenate equine block. Ninety days after the first surgery, 8 mm of new bone was noted on a computed tomography scan, and three 5-mm implants were placed. Histology, performed using confocal laser scanning microscopy, showed a large amount of newly formed bone well characterized with osteon and resorption lacunae, which demonstrated the intense bone remodeling. This study supports the use of rhPDGF-BB in combination with allograft blocks. (Int J Periodontics Restorative Dent 2011;31:383-388.).
