background: diabetes has become the next most widespread disease after cancer. recent studies have found that diabetes and moderate to severe vitamin d defi ciency are associated with reduced bone mineral content; therefore administration of vitamin d may correct these conditions. the purpose of this research is to compare the effect of vitamin d administration on bone to implant contact in dia...

results the rate of first-time successful spinal needle insertion was not significantly different between the clsp and tsp groups (62.9% versus 55.7%, p > 0.05). ease of landmark palpation in the clsp group was not significantly different from that in the tsp group (86.7% versus 76.4%, p > 0.05). the number of needle-bone contacts in both groups were not significantly different (p > 0.05). the ...

context a key determinant for clinical success is the diagnosis of the bone density in a potential implant site. the percentage of bone-implant contact is related to bone density, and the axial stress contours around an implant are affected by the density of bone. evidence acquisition a number of reports have emphasized the importance of the quality of bone on the survival of dental implants. t...

Cardiac tamponade following sternal puncture is fatal and is caused by an anomaly such as foramen sterni, fragility of the bone, or high pressure exerted by doctors on the bone. Contact pressure associated with bone marrow aspiration is unknown; therefore, we examined the contact pressure resulting from bone marrow puncture for aspiration. Prescale, a pressure-sensitive film, was used for measu...

OBJECTIVE The purpose of this study was to develop a model that accurately represents the interface between bone and basal implants throughout the healing process. STUDY DESIGN The model was applied to the biological scenario of changing load distribution in a basal implant system over time. We did this through finite element analysis (FEA, or finite element method [FEM]), using multiple mode...

This article introduces a new technique using histomorphometrics to estimate the extent of bone-to-implant contact that might be expected on an implant surface in relation to the quality of the surrounding bone. Two implant surfaces, one machined and one Osseotite, were compared on the same implant in the same patient Eleven of these custom-made 2-mm-diameter implants were placed in the posteri...

Despite the widespread use of cement as a means of fixation of implants to bone, surprisingly little is known about the micromechanical behavior in terms of the local interfacial motion. In this work, we utilized digital image correlation techniques to quantify the micromechanics of the cement-bone interface of laboratory-prepared cemented total hip replacements subjected to nondestructive, qua...

introduction : supplementation with minerals like calcium has been shown to be effective in preventing bone loss and increasing bone density. thus, it can be assumed that if calcium supplementation is paired with bisphosphonates, greater benefit can be achieved. in this context, we decided to perform this animal study on ovariectomized rats to assess whether bisphosphonate supplemented with cal...
