Combining platelet-rich plasma (PRP) with autogenous bone graft materials has recently been advocated as a means of enhancing rate and quality of new bone formation in regenerative procedures. The aim of this case series was to evaluate the potential of PRP in combination with bone allograft to enhance bone regeneration in alveolar ridge defects exhibiting both vertical and horizontal loss prior to the placement of dental implants. Augmentation resulted in clinical and radiographic gains in both vertical and horizontal components of the osseous defects, thereby facilitating subsequent placement of dental implants. Histologic evaluation of the cases revealed the presence of residual allograft particles surrounded by connective tissue as well as newly formed bone within the grafted areas. However, the addition of PRP did not appear to enhance the quality or quantity of new bone formation over that reported in comparable guided bone regeneration (GBR) studies without PRP.
