GIANT-CELL tumours of bone may be malignant from the onset or malignancy may develop during treatment. They are, therefore, best treated by complete excision where this is surgically possible, with bone grafting of the resultant defect. A patient presented with an osteoclastoma of the lower end of the radius, which was completely excised and replaced by an autogenous fibula graft. The successfu...

Conventional dentistry has provided acceptable treatment alternatives for the partially or fully edentulous patient for decades. Recent innovations have provided clinicians with an assortment of new techniques to restore the function of these patients. Established treatment alternatives have been significantly enhanced, resulting in increased acceptance of predictable dental implant restoration...

Immediate implant placement often requires tissue augmentation simultaneously. Both hard and soft tissue grafting can improve long-term physiologic and esthetic outcomes. Bone replacement grafts are frequently combined with barrier membranes (guided bone regeneration [GBR]). When these materials are resorbable, they are often composed of collagen or synthetic polymers. These techniques do not a...

Restoration of the atrophic maxilla or a maxillary defect following tumour resection presents a challenge to the surgeon and prosthodontist. The atrophic maxilla has an inadequate denture-bearing area and also a reduced bone volume, which may contraindicate the placement of endosseous implants. The International Research Group on Reconstructive Preprosthetic Surgery reported that bone loss in e...

Bone grafting has become an essential part of implant dentistry. Thanks to the advancement of grafting technology, areas that could only be managed with removable dentures or teeth-supported fixed prostheses can now be successfully treated with implant-supported prosthesis. Nonetheless, the complications associated with bone grafting procedures have slowly emerged to be one of the main challeng...

PURPOSE This study was undertaken to evaluate the effect of hyperbaric oxygen therapy on autogenous free bone grafts transplanted from iliac crest to the mandibles of rabbits. MATERIALS AND METHODS A piece of corticocancellous bone harvested from iliac crest was grafted to a same-size bone defect in the mandibles of 16 Japanese white rabbits. In 8 rabbits, 20 and 10 sessions of hyperbaric oxy...

Platelet-rich plasma is an autologous product that is derived from whole blood through the process of gradient density centrifugation. The proposed value of this product in dental implantology and in bone augmentation procedures lies in the ability to incorporate high concentrations of the growth factors PDGF TGF-beta1, TGF-beta2, and IGF as well as fibrin, into the graft mixture. Research has ...
