Bone Graft Research Paper

Describe two of the four varieties of grafts (autografts, isografts, allografts, and xenografts) and the steps taken to lessen graft rejections.

The recovery period after large scale injuries could be shortened. The effects are analyzed in an article that states, “True healing could occur thanks to the cloning of their own cells to help the recovery process” (“Pros and Cons” 5). Basically, the process of cloning healthy cells could be used as an aid in replenishing damage of unhealthy cells. This process, if it were to be actualized, could help recovery progress in anything from pulled muscles to the paralysis of an entire limb. In theory, the same research can be applied in other areas. If this technology is paired with stem cell research, it could result in a method of repairing physical damage. An article that focused on advances in biotechnology stated that “Another use of cloned stem cells could be the growth of replacement tissues in the laboratory” (LaPensee 15). Necrosis, apoptosis, and lymphocyte diapedesis all cause tissue damage or death. These tissues could be replaced by cloned cells of healthy tissues. This shortens recovery periods and leads to healthier tissue growth.

Bone remodeling This is where the body replaces old bone with new bone. The woven bone is replaced by lamellar bone. Osteoclasts remove small bone fragments and osteoblasts deposit spongy bone, converting it to compact

In Brazil 2009, there was an 18 year old boy that had half of his jaw and teeth removed because of a tumor. Scientists took some of his bone marrow and extracted the adult stem cells from it and formed an osteoblast, which is a bone forming cell. Six months after the osteoblast was injected, it started forming new bone material which filled the gaps (NIH Stem Cells). Stem cells could be a genius way to treat many diseases and disorders and it should be supported by everyone.

By having a bone graft procedure, we will restore the bone that you’ve lost in your jaw, which will make it possible to place implants. Having a bone graft will not only make it possible to place your dental implants, but it will also improve your appearance through giving you a full jawline.

Natural bone tissue possesses a nanocomposite structure that provides appropriate physical and biological properties. For bone tissue regeneration, it is crucial for the biomaterial to mimic living bone tissue. Since no single type of material is able to mimic the composition, structure and properties of native bone, nanocomposites are the best choice for bone tissue regeneration as they can provide the appropriate matrix environment, integrate desirable biological properties, and provide controlled, sequential delivery of multiple growth factors for the different stages of bone tissue regeneration. Bioactive polymer/hydroxyapatite (nano) composites are currently being intensively investigated as materials for promotion of bone tissue regeneration

We also offer bone grafting at Beaumont Family Dentistry. In some cases, a patient may not have enough jawbone in a certain area in order to place an implant. Our bone grafting procedure can solve that problem. We can use the latest technology to build up enough bone in the area in order to place your implant.

In 2011, Professor Susmita Bose, of Washington State University, modified a ProMetal 3D printer to bind chemicals to a ceramic powder, creating intricate scaffolds that promote the growth of bone in any shape. Prof. Bose’s goal is to, one day, be able to implant the bone scaffold with bone growth factors in such a way that the implant is dissolved by natural bone material in even load-bearing bone structures.

Bone is surrounded by a thin membranous layer of soft tissue called periosteum (Singh, 2017). When the bone breaks it bleeds from torn ends because of the disruption of the supplying blood vessels. And quite naturally the periosteum is also torn. A fracture hematoma forms and white blood cells march in to clean up the area that is injured. The periosteum is the primary source of osteoblasts, which plays a huge role in fracture healing (Singh, 2017). After the hematoma formation, the next step is callous formation with the formation of cartilage and bone and then the remodeling phase consisting of the osteoclasts and the osteoblasts reshaping the bone to its original state (Patton, 2012).

In treatment groups removal of the circular layer of periosteum was followed by omentalfree graft sandwich replacement The femoral head was relocated. The articular capsule and the gluteal muscles were sutured with vicryl 4-0 stitches. The skin was closed with nylon 4-0 stitches. The animals were euthanized by CO 2 inhalation after general anesthesia with ketamine-xylazine at 4, 12, 21, 28, 42 and 52 days after the surgery. Both femoral heads were harvested and the soft tissue was excised. The specimens were fixed in formalin for a week. Following decalcification in formic acid for two weeks, Paraffin blocks of 4 µm were cut, and the sections were stained with hematoxylin and eosin. All the histologic specimans were numbered randomly. The result of present study showed the omental free graft sandwich implantation can improve femoral head repair in experimentally induced

The trabecular bone is a form of osseous tissue that is found in the proximal and distal ends of long bones, along with the bones of the skull, pelvis, ribs and the vertebral bodies. The trabecular bone undergoes remodeling every two to eight months in order to accommodate the load of physiological stress and mechanical forces on the bone (Huiskes et al. 2000). Bone remodeling is the reshaping or replacement of bone during growth and following injuries such as fractures, but it also occurs in cases of micro-damage (Kini and Nandeesh, 2012). This supports Wolff’s Law, which states if loading on a particular bone increases, the bone will remodel over time to strengthen itself to resist that type of loading (Frost, 1994) The use of trabecular

The average union time for 29 patients who didn't undergo additional surgery was 9.97 months (2-36) with 9.81 for PFP and 10.15 for FFP (the mean union time for hemicortical resection was 6.5 months, while for those underwent two osteotomies was 11.77 months). There were 5 (14.7%) cases of nonunion. In 4 cases the non-union was treated by bone graft augmentation at the non-union site, while in 1 case the non-union was due to infection and the frozen autografts was removed with conversion to vascularised fibular

The basic concept for guided bone regeneration includes placing physical barriers to protecting the blood clot, maintaining the blood supply to the defect area, releasing growth factors, and isolating the bone defect to allow access for bone cells to cause bone regeneration.

Bone at the tissue level undergoes remodeling: it is continuously being resorbed and rebuilt (or formed). A negative balance between bone resorption and formation, frequently due to excessive resorption, is the basis of many bone diseases.

Lately, there is an emerging innovation whereby organs are created to form and increase in size by a process of inorganic accretion, from the patient’s cell. This field of medicine is known as the regenerative medicine. In addition to this, there are basically various types of regenerative medical
