BACKGROUND Maxillary sinus floor augmentation procedures are currently the treatment of choice when the alveolar crest of the posterior maxilla is insufficient for dental implant anchorage. This procedure aims to obtain enough bone with biomaterial association with the autogenous bone graft to create volume and allow osteoconduction. The objective of this study was to histologically and histome...

bone graft and laser irradiation in the bone repair. Defects were created in the skull of 30 rats and filled with autogenous graft and FS derived from snake venom. Immediately after implantation, low-power laser was applied on the surgical site. The animals were divided in: control group with autogenous graft (G1), autogenous graft and laser 5 J/cm2 (G2), autogenous graft and laser 7 J/cm2 (G3)...

background: various materials and techniques have been developed to facilitate bone healing process and reduce its healing period. in recent studies, it is pointed out that, platelet-rich fi brin (prf) which is derived autogenously from the own blood of the individuals, increase regeneration and accelerate the healing of the wound, due to the consisting various growing factors. the aim of the e...

PURPOSE Platelet-rich plasma (PRP) is potentially useful as an adjunct to allograft and xenograft materials in oral and maxillofacial bone and implant reconstructive surgery. This study compares bone healing and formation in 4 cranial defects in rabbits grafted with autogenous bone, xenograft, and xenograft with PRP (with a no-graft group as a control). MATERIALS AND METHODS Fifteen New Zeala...

In anterior lumbar spinal fusion, patients treated with rhBMP-2 on a collagen sponge carrier had statistically superior outcomes compared to patients treated with autogenous bone graft. A collagen sponge carrier should replace autogenous bone graft for this patient population.

OBJECTIVE This report focuses on the biological events occurring at various intervals following autogenous bone grafting of large-volume defects of the knee joint's femoral condyle secondary to osteochondritis dissecans (OCD) or osteonecrosis (ON). It was hypothesized that the autogenous bone graft would integrate and the portion exposed to the articular surface would form fibrocartilage, which...

BACKGROUND Autogenous bone graft harvesting from the iliac crest is associated with donor site morbidity. The aim of this report is to describe the use of piezosurgery as an attempt at morbidity reduction. MATERIALS AND METHODS A piezosurgical handpiece and its selection of tips can easily be accommodated in an iliac crest wound to osteotomize and allow the harvest and delivery of autogenous ...

A variety of materials and procedures are used to create adequate bone volume in the maxillary sinus for placement of endosseous implants in the posterior atrophic maxilla. This review used the structured method of meta-analysis to evaluate the survival of the implants placed into various materials that have been used in the maxillary sinus with the sinus lift procedure. A MEDLINE computer sear...

INTRODUCTION Secondary bone grafting consists in a routine procedure on the treatment of patients with alveolar cleft. Usually, it is performed by the end of the mixed dentition, when the permanent canine is erupting, with autogenous cancellous bone from the iliac crest. OBJECTIVE The present article discusses the alternative of autogenous bone grafting with allogeneic bone, obtained from hum...

Autogenous bone grafts from the iliac crest have long been the gold standard for repair and reconstruction of bone; however harvesting of the grafts from the iliac crest is associated with donor site morbidity, particularly chronic pain. The bone morphogenetic proteins (BMPs) are soluble bone matrix glycoproteins that induce the differentiation of osteoprogenitor cells into osteogenic cells and...
