Our aim was to evaluate the effects of lateral cortical anchorage on the primary stability of implants subjected to immediate loading. Implants were placed into bovine bones with monocortical anchorage (implant placed through the cortical bone of the crest) and bicortical anchorage (the crest cortical bone plus one cortical bone on the lateral side). Loads of 25N and 50N were applied to the implants in different cycles. The implant stability quotient (ISQ) was measured before and after the cyclic loadings. Under 25N load there was no difference in ISQ between 1800 cyclic loading and preloading, but the values decreased significantly after 3600 cyclic loading in both groups (p<0.05). Under a 50N load the ISQ value after 1800 and 3600 cyclic loading decreased in the monocortical group (p<0.05), but there was no difference between 1800 cyclic loading and preloading in the bicortical group, and the ISQ in the bicortical group was higher than in the monocortical group after 1800 cyclic loading (p<0.05). Our results suggest that the stability of implants with bicortical anchorage decreased more slowly under higher loads.

How Does Diploic Space Thickness Change With Age?
J Craniofac Surg
January 2025
Division of Plastic and Reconstructive Surgery, The Warren Alpert Medical School of Brown University.
Background: Cranial defects from trauma, surgery, or congenital conditions require precise reconstruction to restore cranial vault integrity. Autogenous calvarial grafts are preferred for their histocompatibility and biomechanical properties, but their success depends on a well-developed diploic space. Although prior studies have described overall skull thickness development, less is known about how diploic thickness changes through adulthood.

Generating Virtual Bone Scans for the Purpose of Investigating the Effects of Cortical Microstructure.

Evaluating the contribution of microstructure to overall bone strength is tricky since it is difficult to control changes to pore structure in human or animal samples. We developed an open-source program that can generate three-dimensional models of micron-scale cortical bone. These models can be highly customized with a wide array of variable input parameters to allow for generation of samples with high similarity to CT scans of cortical bone or with specific geometric features.

Military training improves tibial density, structure, and estimated strength; however, men and women may adapt differently. Most work performed in military populations has assessed changes in bone health during initial entry programs, a timeframe at the beginning of a service member's career when bones may be more adaptable to a novel mechanical stimulus. The purpose of this investigation was to examine changes in tibial volumetric bone mineral density (vBMD), structure, and estimated strength, and biomarkers of bone metabolism (P1NP, osteocalcin, TRAP5b, sclerostin) between male and female candidates measured at the start and end of United States Marine Corps Officer Candidates School (OCS), a 10-week military training program attended by older service members (~ 25 y/o) who may have previous military experience.
