Bone grafting

Bone grafting is performed to restore bone that has been lost due to injury, trauma, or disease. Injury may cause haematoma and bleeding from adjacent structures to occur. Haematoma is clotting of blood that occur in any specific region such as around the broken bone ends. This event is localized. Two ends involved are proximal and distal bone end which is the medium for osteonal healing (ossification) to occur. Ossification is the process of bone formation that is usually beginning at particular

Bone is the substance that forms the skeleton of body. It is composed chiefly of calcium phosphate and calcium carbonate. It is also serves as a storage area for calcium, playing a large role in calcium balance in blood. The main function of bone is they support and protect various of organs in body, stores blood cell and store minerals. Bone can be categorized as a fragile part in body. The replacement and repair of bone due to accident, cancer or bone defect is a major clinical challenge which

Bone Grafting and Sinus Lift with Your Prosthodontist in Oviedo, FL Getting dental implants is a wonderful solution for many individuals. Implants are placed in your facial bone, and they remain there permanently. The implants, which are tiny titanium screws, serve as prosthetic roots. Crowns are placed over the implants, so you also have prosthetic teeth. Unfortunately, not everyone has enough bone to support the placement of implants. This usually indicates bone loss due to advanced gum disease

months post-operatively (1). Bone resorption following tooth loss occurs in both a lingual and apical direction, resulting in an edentulous maxilla that is narrower with a loss of vertical height. This resorption is responsible for the edge-to-edge or reverses occlusal relation of the residual crests that is often observed in patients with completely edentulous maxillae (2). At times, ridge resorption in the maxilla is so severe that is necessary to augment the bone in order to place an implant

a material or technique must histologically demonstrate that bone, cementum and a functional periodontal ligament (a new attachment apparatus) can be formed on a previously diseased root surface. Bone grafts and their synthetic substitutes have been used in an attempt to gain this therapeutic endpoint. However, among the graft materials to date, only autogenous bone of extraoral or intraoral sources and demineralized freeze dried bone allograft have human histological evidence to include them as

I. INTRODUCTION The technique of grafting dates back to the beginning of agriculture. Although it can be labor-intensive, grafting has continued to be used in fruit and nut trees because of the immense benefits. Different plants produce different qualities of fruits and nuts, and not always consistently. And, because tree fruits are nearly impossible to reproduce from cuttings, grafting has become the most popular technique for fruit tree propagation. Grafting helps to produce a superior and highly

a) Describe THREE propagation techniques that could be used in Asexual plant propagation. Technique One: Budding Name of plant chosen: Citrus 1. The first step in Budding is to choose the rootstock and budwood for the citrus plant budding. When selecting the rootstock make sure it is healthy and strong and less than 7 years old but at least as tall as 30cm. Make sure bud is not a flower bud. 2. The next step is to prepare the rootstock for the budwood. The best way to do this is to cut a T-shape

Junctional epidermolysis bullosa (ep-i-der-mo-lie-sis bu-low-suh), also known as JEB, affects about 25,000 people in the US and roughly 500,000 people around the world. Most of these people are young children because JEB is often lethal and 40% of those with the disease do not survive until adolescence. JEB is a recessive genetic connective tissue disorder, but there are currently no genetic tests that can be done to see if parents may be carriers of the disease. Parents usually find out that they

Bone regeneration is a complex, well-orchestrated physiological process of bone formation, which can be seen during normal fracture healing, and is involved in continuous remodelling throughout adult life. However, there are complex clinical conditions in which bone regeneration is required in large quantity, such as for skeletal reconstruction of large bone defects created by trauma, infection, tumour resection and skeletal abnormalities, or cases in which the regenerative process is compromised

material and processes. Typically ceramics have been used in surgical replacements such as bones and teeth. These ceramics must be designed and optimized in order to perform in the body’s aggressive internal environment. Newer ceramics are being researched in order to improve structure, functionality, and life expectancy. Some ceramics like calcium phosphate ceramics increase the bioactivity by stimulating bone growth2. Some are designed to incorporate drugs that can be release by external stimuli
