Abstract:

Analysis of stress concentration in bone tissues and screw dental implants was per-formed on a model of screw join of the implant and surrounding bone tissues under the action of normal and tangential loads. The computations were performed by the bounda-ry element method for the plane strain state. It was assumed that those hollows in the spongy bone, which had formed in the bone after the implant insertion, are conformed to the screw thread on the implant. Bone tissues are considered as an isotropic and homo-geneous linear-elastic materials. It has been found that with the increasing in the s

Abstract:

An original method for studying the morphometric characteristics of spongy bone tissue was proposed. Using this method the distribution of the density of the spongy bone tissue of the distal metaepiphysis of the radius was studied. A decrease in the content of spongy bone tissue along the longitudinal axis of the bone has been experimentally proved. Modeling the mechanical properties of spongy bone tissue, according to the known versions of models for the elastic modulus of discontinuous media, makes it possible to calculate the behavior of bone tissue in conditions of various types of interac

Our aim was to use stereology to quantify the volume fraction of osteocyte lacunes, volume fraction of large blood vessels, numerical density of osteocyte lacunes, volume of osteocyte lacunae and bone surface in series of micro-CT images representing samples of spongy and compact bone of human tibia. The spongy bone had a smaller volume fraction of osteocyte lacunes, a greater numerical density of bone lacunes, a smaller volume of the lacunes within the same bone volume and a greater bone surface density when compared to the compact bone. Stereology provided us with data on hierarchical organi

Abstract:

The development of bioactive and cell-responsive materials has fastened the field of bone tissue engineering. Gellan gum (GG) spongy-like hydrogels present high attractive properties for the tissue engineering field, especially due to their wide microarchitecture and tunable mechanical properties, as well as their ability to entrap the responsive cells. Lactoferrin (Lf) and Hydroxyapatite (HAp) are bioactive factors that are known to potentiate faster bone regeneration. Thus, we developed an advanced three-dimensional (3D) biomaterial by integrating these bioactive factors within GG spongy-lik

Abstract Some bones of the human skeleton are porous inside and resemble a sponge. The cancellous bone tissue forms the epiphyses of the long bones and practically the entire volume of the cancellous bones. It is known that the structural units of the spongy substance – trabeculae, are located along the lines of action of the greatest mechanical loads created by the muscles attached to the skeleton. If the load during life changes due to some reason, for example, injuries, the characteristics of the profession or lifestyle, then the cancellous bone rebuilds its structure in order to withstand

Living bone tissue, like many other connective tissues, is a structural material that adapts its form and microstructure to changing environmental loading conditions. Bone tissue adapts not only its shape, but also its density and the details of its microstructure including its anisotropy. The anisotropy of bone is adapted in both its degree or strength and in the orientation of its principal axes of symmetry. These adaptive features of bone tissue are often referred to as aspects of Wolff’s law, although, strictly speaking, the term “Wolff’s law” applies only to the structural adaptation of s

Abstract:

The new method of restoration of injured articular cartilage using plasty of intraoperative bone-cartilage defects with combined allograft based on biologic porous carrier and cell culture from stroma of costal cartilage. The transplantation of allogenic culture of chondroblast cells on demineralized spongy substance «Lioplast» ensure еру the formation of hyaline cartilage tissue on the site of defect and amplified development of microcirculatory network in subchondral bone. The heterotopic principle obtaining cellular material allows to perform low-traumatic operations.

MR bone imaging (also known as CT-like MRI) is a novel imaging technique with short TEs that was recently developed. It is capable of visualizing structures such as cortical bone, spongy bone, and calcification that are difficult to visualize using conventional MR imaging due to the low proton density and the very short T2- and T2* tissue.

Introduction: The lumbar lordosis angle measured by radiology under normal conditions is between 135-1400. Any deviation from the values is associated with a change in static-dynamic loads and should translate into a change in bone tissue within the lumbar-sacral border, which results from a change in the distribution of load forces acting on individual parts of the vertebral bodies. The aim: To determine the relationship between individual variants of lordosis (hypolordosis, hyperlordosis, norm) and the general density of the spongy part of individual vertebral bodies and in selected zones of

The article contains theoretical studies aimed at identifying the load and detecting the factors that have a negative impact on implants. One of the reasons behind implant disintegration is bone tissue resorption, which is due to overload. Direct measurements of the oral cavity stresses affecting the tissues around the implants are basically impossible. The purpose here is to choose the optimal inclination of the implant in relation to the vertical axis in view of mismatch of the mandibular and maxillary alveolar arches.

Atrophy of the alveolar process of the upper jaw and part of the lower jaw is often observed after the tooth extraction. The loss of bone tissue of the alveolar process of the upper jaw and part of the lower jaw in the postmenopausal period is associated with changes in the hormonal status of the female body, in particular with estrogen deficiency. It is known that bone remodeling occurs on the average at 5% in the cortical and at about 20% in the spongy layers of bone tissue annually. A characteristic peculiarity of bone remodeling is that this process is heterogeneous and different for each

Bone is a vascularized and connective tissue. The cortical bone is the main part responsible for the support and protection of the remaining systems and organs of the body. The trabecular spongy bone serves as the storage of ions and bone marrow. As a dynamic tissue, bone is in a constant remodelling process to adapt to the mechanical demands and to repair small lesions that may occur. Nevertheless, due to the increased incidence of bone disorders, the need for bone grafts has been growing over the past decades and the development of an ideal bone graft with optimal properties remains a clinic

Abstract:

Bioerosion trace fossils in bones are defined as biogenic structures that cut or destroy hard bone tissue as the result of mechanical and/or chemical processes. Under the premise that their paleoecological potential can completely be realized only through correct taxonomic assignment, this work focuses on the methodology for naming these biogenic structures. Thus, we propose the following ichnotaxobases in order to assist in naming trace fossils in bones: general morphology, bioglyphs, filling, branching, pattern of occurrence, and site of emplacement. The most common general morphologies are:

Ti-based alloys are widely used in medical applications. When implant devices are used to reconstruct disordered bone, prevent bone resorption and enhance good bone remodeling, the Young’s modulus of implants should be close to that of the bone. To satisfy this requirement, many titanium alloys with different biocompatible elements (Zr, Ta, Mo, Si etc.) interact well with adjacent bone tissues, promoting an adequate osseointegration. Four new different alloys were obtained and investigated regarding their microstructure, mechanical, chemical and biological behavior (in vitro and in vivo evalua
