Primary stability is absence of mobility in the bone bed after mini-implant placement and depends on bone quality among other factors. Bone quality is a subjective term frequently considered as bone density. The aim of this preliminary study was to evaluate bone density in two bovine pelvic regions and verify the primary stability of miniscrews inserted into them. Forty bone blocks were extract...

This report assesses the results following sinus floor augmentation performed 14 years previously in which bovine bone xenograft material was used without implant insertion. After sinus floor augmentation, using a 20:80 mixture of autogenous bone and inorganic bovine bone material (Bio-Oss), bone biopsy specimens were taken from the grafted site, processed with Donath's sawing and grinding tech...

Progressive loss of bone mineral density around the femora! component of total hip replacement continues to pose a threat to long term prosthetic survival. A linear study was undertaken to measure bone mineral density on a monthly basis following total hip arthroplasty in 11 male patients. The opposite femur was used as the control measurement. Bone mineral density was unchanged at two mo...

The human bone is multiphase material consisting of collagenous matrix interspread with mineral crystals. Magnesium participates in the normal formation and remodelling of bone. Magnesium deficiency has been associated with a number of clinical disorders including osteoporosis. The present investigation focuses on quantitative estimation of magnesium, an inorganic constituent of bone and determ...

Dietary P supplied to feedlot cattle is important because an inadequate supply will compromise performance, whereas excess P may harm the environment. However, P requirements of feedlot cattle are not well documented. Therefore, 45 steer calves (265.2+/-16.6 kg) were individually fed to determine the P required for gain and bone integrity over a 204-d finishing period. The basal diet consisted ...

background: osteoporosis is a major public health concern around the world. it has been shown that bone mineral den­sity is correlated to anthropometric measures like height and weight, but this association may vary depending on ethnic and environmental factors. the aim of this study was to identify probable relations between anthropometric measures and bone mineral density. methods: in this po...

The mineral front consists of large populations of organically enshrouded calcified microspheres (filamentous clusters) about 1 micron in diameter and associated smaller numbers of variably dense nanospheres, 30 40 nm in diameter. The discrete objects persist and modulate in maturity, and may constitute a variable “qualitative” factor in the skeletal inorganic phase, exemplified by the biomecha...
