Grafting of the maxillary sinus is an established treatment modality to provide sufficient bone for the fixation of dental implants. We stated the hypothesis that the porous fluorohydroxyapatitic (FHA) biomaterial FRIOS Algipore could be used as a suitable biomaterial for sinus grafting in severely atrophic maxillae. To investigate the accuracy of our hypothesis, 69 trephine specimens from 26 p...

Objective- Current trends emphasize the acceleration of fracture healing on the ground that in doing so, the limitation of mobility and complications associated with recovery period are reduced. The present study aims to compare autogenic costal cartilage with Chitosan scaffold in canine humeral defect healing. Design- Experimental study Animal-15 adult male dogs Procedures-...

109 Bone grafting is an important aspect of foot and ankle surgery.1 Despite the long history and widespread use of bone grafts and substitutes,2 there have been few studies documenting patterns of utilization of bone grafting by podiatric surgeons. A survey on the use of bone grafts among orthopedists was reported in 1984 by Miller et al.3 The present study was undertaken in order to determine...

Literature regarding the outcome of maxillary sinus floor elevation to create sufficient bone fraction to enable implant placement was systematically reviewed. Bone fraction and implant survival rate were assessed to determine whether grafting material or applied growth factor affected bone fraction. Trials where sinus floor elevations with autogenous bone (controls) were compared with autogeno...

The purpose of this study was to investigate the quality of bone at grafted implant sites in the anterior maxilla. Grafting of these sites was necessary because of insufficient bone volume in a buccopalatinal direction (width at the top of the crest 1-3mm). Reconstruction was performed with chin bone (N=5), chin bone and a resorbable Bio-Gide GBR membrane (N=5) or Bio-Oss spongiosa granules in ...

PURPOSE Implant beds with an insufficient amount of cortical bone or a loss of cortical bone can result in the initial instability of a dental implant. Thus, the objective of this study was to evaluate the effect of bone cement grafting on implant initial stability in areas with insufficient cortical bone. METHODS Two different circumferential defect depths (2.5 mm and 5 mm) and a control (no...

Nonunion following diaphyseal forearm fracture is an uncommon complication in children. Compression plate fixation with bone grafting has been the standard method to treat this complication. We report a case of hypertrophic nonunion of the ulna in a child who was treated surgically using an elastic stable intramedullary nail (ESIN) without bone grafting. The nonunion healed 4 months after surgery.

IntrOductIOn Treatment of large osseous bone defects is challenging. Autologous bone grafting is still the “biologic gold standard” against which all other forms are judged. Autograft enhances union by providing osteoconductive, osteoinductive and osteoprogenitor material to the fracture, nonunion and osseous defects. Unfortunately finite amount of graft available from each individual and addit...

Bone grafts are often necessary to provide support, fill voids, and enhance biologic repair of skeletal defects. Autogenous bone recovered from the patient’s own iliac crest is generally considered the gold standard of bone grafts. There is a need for alternatives, however, because of limited autograft quantities, donor site morbidity, and other problems including limited biologic performance. ...
