background and aim . vertical and horizontal bone resorption of the alveolar ridge are common in edentulous jaws. in the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities to crestal bone. sinus floor augmentation is an established way of increasing the height and volume of bone in the posterior region of the maxilla, which increa...

Background/introduction MRI-guided high-intensity focused ultrasound (MRHIFU) therapy can relieve pain associated with metastatic and benign bone tumours in patients who fail to respond to conventional radiation therapy. However, since existing MR-thermometry techniques do not provide temperature information within the bone, HIFU exposures in bone are currently monitored using temperature chang...

a 10-year-old boy was referred to us for evaluation of fuo accompanied with bone pain in both calves. three hours after intravenous injection of 13 mci of 99mtc-mdp, whole body scan in multiple spot views was performed. the scan showed symmetrical areas of diffusely increased tracer uptake in multiple long bones. histopathologic evaluation confirmed osteosclrosis and fibrotic changes without an...

longevity of osseointegrated implants are intensely influenced by biomechanical factors. control of these factors prevents mechanical complications, which include fracture of screws, components, or materials veneering the framework. in this study, the impact of length and threads pitch of dental implants on the stress distribution and maximum von mises stress in implant-abutment complex and jaw...
