Evaluation of allogeneic bone blocks adn PRF in reconstruction of major alveolar bone defects

Journal Title: Prosthodontics - Year 2016, Vol 66, Issue 6

Abstract

Introduction. A decline in patients’ acceptance of removable prosthetic restorations, information obtained from dentists, as well as media coverage of possible implant restorations of dental defects have made bone augmentation within the vertical and horizontal dimension increasingly common as a procedure necessary before implantation in the area of an atrophied alveolar ridge. Aim of the study. To analyse the possibility of using frozen, allogeneic, radiation-sterilized bone grafts in the form of bone blocks for the reconstruction of an atrophied alveolar ridge. Material and metods. The study material comprised 32 patients of both genders (aged 19-59 years). They underwent an alveolar ridge augmentation in 2012–2015. The restoration of bone tissue defects was carried out with allogeneic, frozen, radiation-sterilized, corticocancellous blocks. Overall, 32 grafting procedures were performed, including 19 alveolar ridge augmentations in the mandible and 32 in the maxilla. Results. A correctly prepared bone block allowed for successful alveolar ridge augmentation and enabled the surgeon to embed intraosseous implants later on, according to the approved treatment plan. Radiological testing showed optimal shape of the reconstructed ridge allowing functional and aesthetic success of implantation. Conclusions. Frozen, radiation-sterilized allogeneic bone blocks present a good and durable bone replacement material allowing effective and long-lasting augmentation of an atrophied alveolar ridge. Histopathological testing confirmed new bone formation. The developed technique of bone block preparation prevented excessive and uncontrolled resorption of the biomateriał.
