background: bone tissue engineering requires materials that are biocompatible, mechanically suited for bone function, integrated with the host skeleton, and support osteoinduction of the implanted cells for new bone formation. the aim of this study was to compare the osteogenic potential of xenograft with hydroxyapatite/β- tricalcium phosphate (ha/β-tcp) scaffold. methods: new zealand rabbits (...

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-...

Bone stock deficiency in primary as well as in revision total knee arthroplasty (TKA) represents a difficult problem to surgeon with regard to maintaining proper alignment of the implant components and in establishing a stable bone-implant interface. Different surgical procedures are available in these situations, for instances the use of bone cement, prosthetic augments, custom implant, and wi...

Introduction Surgical management of massive bone defects is very challenging in terms of estimating possibilities of saving the extremity and adequate method that can make it possible. Selection of methods is additionally limited in the presence of infection at site of defect. Case report The female patient, diagnosed with Ewing sarcoma was treated by segmental bone resection and implantation...

  Aneurysms of gastric vessels (Dieulafoy`s disease, caliber-persistent artery) are thought to be of malformative rather than degenerative origin. They are usually single, located in the submucosa, usually on the lesser curvature, and characterized by a large tortuous vessel surmounted by a small defect...

stafne bone defect is a bone depression containing salivary gland or fatty soft tissue on the lingual surface of the mandible. the most common location is within the submandibular gland fossa and often close to the inferior border of the mandible. this defect is asymptomatic and generally discovered only incidentally during radiographic examination of the area. stafne bone defect appears as a w...

Objective- To evaluate the role of greater omentum incorporation of coral in healing of the long bone defect in dog model. Design- Experimental in-vivo study. Animals- Sixteen adult mongrel male dogs weighing 26.2±2.5 kg, free of evident infectious or parasitic illnesses were used in this study. Procedures- The operative procedure was undertaken under general anesthesia. Radial bone was expo...

We report 127 cases who have had elective operation on cranium because of skull bone defect during 1984-1989. Usually repair of skull bone defect and preserving normal anatomy were the major therapeutic goals. 10, II In these cases a new surgical technique is described which can successfully accomplish these goals in a single but staged operative procedure.

the purpose of the present randomized clinical trial study was to compare the effectiveness of bovine porous bone mineral (bpbm) with and without plasma rich in growth factors (prgf) in the treatment of mandibular class ii furcation defects.in seven patients, nine pairs of symmetric buccal or lingual mandibular class ii furcation defects were treated. in each patient, one defect received bpbm (...
