OBJECTIVE To assess the bone density of dental implant sites using CBCT and Simplant software, and establish a quantitative ranges for each bone quality classification according to the classification of bone quality proposed by Lekholm and Zarb. PATIENTS AND METHODS 128 patients' jaw bone were scanned by CBCT, the images were reconstructed by the Simplant software. The bone density of 236 pot...

In the present study, the effect of glucosamine administration (1.5 or 3 g/day) on cartilage and bone metabolism was investigated in bicycle racers, using cartilage‑ and bone‑specific biomarkers, including C‑terminal cross‑linked telopeptides of type II collagen (CTX‑II), C‑terminal propeptides of type II procollagen (CPII), N‑terminal telopeptide...

To ensure the long-term success of a dental implant, it is imperative to understand how chewing loads are transferred through implant prosthetic components surrounding bone tissue. The stress distribution depends on several factors, such as load type, bone–implant interface, shape and materials fixture quality quantity bone. These aspects fundamental importance stability evaluate remodelling ca...

Matrix metalloproteinase (MMP)-9 has been shown to contribute to blood-brain barrier (BBB) disruption, infarct formation, and hemorrhagic transformation after ischemic stroke. The cellular source of MMP-9 detectable in the ischemic brain remains controversial since extracellular molecules in the brain may be derived from blood. We here demonstrate that bone marrow-derived cells are the major so...

Diabetes mellitus is known to have late complications including micro vascular and macro vascular disease. This review focuses on another possible area of complication regarding diabetes; bone. Diabetes may affect bone via bone structure, bone density, and biochemical markers of bone turnover. The aim of the present review is to examine in vivo from humans on biochemical markers of bone turnove...

I recently read an interesting article in Diabetes Care (1) that showed that treatment with dipeptidyl peptidase-4 (DPP-4) inhibitors could be associated with a reduced risk of bone fractures in type 2 diabetic patients. As the authors pointed out, since experimental data in animal models suggested that incretins such as glucagon-like peptide-1 (GLP-1) and gastric intestinal polypeptide (GIP) s...

We retrospectively reviewed 40 hips in 36 patients who had undergone acetabular reconstruction using a titanium Kerboull-type acetabular reinforcement device with bone allografts between May 2001 and April 2006. Impacted bone allografts were used for the management of American Academy of Orthopaedic Surgeons Type II defects in 17 hips, and bulk bone allografts together with impacted allografts ...
