PURPOSE This study compared the bone regeneration response of different bone graft materials inside canals within anodized titanium implants in cortical and cancellous bone. MATERIALS AND METHODS Upper and lower transverse canals were created in anodic oxidized-surface titanium implants to serve as sites for cortical and cancellous bone regeneration, respectively. The canals were filled with ...

This paper introduces the culture preparation of ovine, bovine and human cancellous bone cores to be used in an explants model Zetos. The three dimensional (3D) bone cores were prepared and evaluated for all three animals. Bone cells in vivo constantly interact with each other, migratory cells, surrounding extracellular matrix (ECM) and interstitial fluid in a microenvironment, which continuous...

BACKGROUND Descriptions of fracture healing almost exclusively deal with shaft fractures and they often emphasize endochondral bone formation. In reality, most fractures occur in metaphyseal cancellous bone. Apart from a study of vertebral fractures, we have not found any histological description of cancellous bone healing in humans. PATIENTS AND METHODS We studied histological biopsies from ...

This study was aimed at elucidating the temporal changes of microarchitectural and mechanical parameters of cancellous bone in the osteoporotic rabbit model induced by ovariectomy (OVX) combined with glucocorticoid (GC) administration. Osteoporotic (OP) group received bilateral OVX combined with injections of GC, while sham group only received sham operation. Cancellous bone quality in vertebra...

To investigate whether growth hormone (GH) and 17β-estradiol (E2) replacement can prevent osteopenia induced by pituitary and ovarian hormone deficiency [by hypophysectomy and ovariectomy (HX+OV)], we administered relatively low doses of GH (2.3 IU ⋅ kg-1 ⋅ day-1) and E2 (100 μg ⋅ kg-1 ⋅ wk-1) in experiment 1 and relatively high doses of GH (13.5 IU ⋅ kg-1 ⋅ day-1) and E2 (3,500 μg ⋅ kg-1 ⋅ wk-...

The aim of the present study was to examine the influence of gastrectomy (GX) on cortical and cancellous bones in rats. Twenty male Sprague-Dawley rats were randomized into the two groups of 10 animals each: a sham operation (control) group and a GX group. Seven weeks after surgery, the bone mineral content and density (BMC and BMD, resp.) and the mechanical strength of the femur were determine...

BACKGROUND This study aimed to analyze differences in necrotic changes between cortical and cancellous bone in resection margins after segmental mandibulectomy for advanced mandibular osteoradionecrosis. METHODS Anteroposterior bone specimens from eleven patients who underwent segmental mandibulectomy with simultaneous free fibula flap reconstruction for advanced osteoradionecrosis were analy...

A clinical case of bilateral cleft palate repair using previous tongue flap followed by Alveolar Bone Grafting(ABG). After pre-surgical orthodontics a surgical procedure whereby Flaps were reflected, nasalbeds prepared on both sides. cortico-cancellous bone 2 cm was harvested from iliac crest and grafted inclefts. Patient is kept follow up to monitor healing, postoperative results any post- ope...

The present article describes a titanium mesh procedure used for bone augmentation in the treatment of severe maxillary atrophy. A mix of iliac cancellous bone and anorganic bovine bone in a 1:1 ratio is proposed for achieving the best bone quality at the time of implant placement, which is performed 5 to 6 months after the augmentation surgery. This procedure provides for 3-stage surgery using...
