Introduction
So far, various techniques have been used for reconstruction and regeneration of maxillary and mandibular bone defects. Autogenous bone grafting, guided bone regeneration (GBR), distraction osteogenesis and nerve transpositioning are among these regenerative techniques (1-8). Decision making for the treatment could be influenced by the type, size and location of the bone defects (2, 3, 9, 10). GBR had high success rate in treating small alveolar defects such as dehiscence or fenestration. Regenerative bony walls around the defect with ingrowing blood vessels can begin osteogenesis (11) larger bone defects with insufficient regenerative walls and an low quality avascular bed need varied amount of autogeneous bone graft from extra oral or intra oral donor sites, however, the patient may suffer from complications in donor site as well as bone graft resorption.(10, 12-15)
Recent research has been focused on distinguishing the most successful augmentation surgery for restoring deficient bone (4, 16-18). Surgical techniques and survival of the bone graft has been vastly highlighted in the literature. ,However, the importance of recipient site on success rate of augmentation procedure has been less issued (16).
We have focused on recipient site characteristics in ABC classification (16) as follow:
1. Presence of vertical regenerative walls in both sides of the recipient site or one site which classified as A and B group respectively. Absence of regenerative walls in both side named C group. (Fig.1, 2 ).
2. Width of the base which divided to 3 groups: 1: More than 5 mm; 2: between 3-5 mm; less than 3 mm.
Sinus cavity and extraction sockets were totally excluded from this classification because the healing process h...

...treatments are considered despite of all the morbidities and possible graft resorbtions.
But with appropriate case selection and modifying a c3 defect to a A1, , autogenous regenerative walls are created that will lead to a simple and cost benefit treatment.
Conclusion
Amount of the vertical or horizontal augmentation, depicting high quality bone like tissue during reentry, success rate of the dental implants in bone graft area and cloudy histological figures, never can lead to make decision for selecting best treatment for the patients with deficient alveolar ridge, if we do not have detailed map of the recipient bone.
With ABC recipient site classification surgeons gain some insight in to regenerative potential of the surgical bed and can consider some modifications to help increasing of success rate of bone healing and decreasing morbidities of donor sites.
Bone Grafting: This process will help you if your jawbone isn’t strong enough to house a new implant. In general, it bone grafting is minimally invasive procedure.

Reconstruction using donor tissues will have two surgical sites and scars. Recovery takes a bit longer. But, they look more natural than implants. There is also no worries about implant ruptures or the need for future
There are many causes for needing a bone replaced, a common one being arthritis. The hip and knee are both effective bones in the body when uncompromised by osteoarthritis because they are structurally designed to manage stress from loading in effective ways. In hip and knee replacement surgery, common surgeries, there are advantages and disadvantages relating to recovery time and lasting bone health. By examining the structure and functionality of the knee and hip with an emphasis on artificial bone, researchers are continuing to expand upon the field of bone replacement surgery.
The lowermost part of the face, the chin, plays a significant role in maintaining the facial profile. A more younger, attractive and healthier look is achieved by a stronger chin. Chin augmentation using surgical implants tends to provide better balance to the facial features by modifying the underlying face structures. Proper jaw bone modification helps in achieving chin augmentation. More dramatic results are offered in the augmentation procedure which makes use of jaw implants rather than prosthetic implants. An aesthetic chin surgery aims to correct a weak chin in addition to improving the facial balance. Patients who have normal functioning teeth and jaw development are mainly recommended to undergo chin augmentation procedure which involves the use of implants. The dimensions of the jaw are altered by fixing a biocompatible implant over the bony part of the lower jaw. Depending upon the augmented region, you can either enhance the size of your face or can make your chin more strong or wide. Sometimes, inorder to keep a balance with the facial proportions, this surgery is combin...
Our own immune system such as macrophages help in restoring the damage in the heart for example, damage caused by myocardial infarction. Macrophages responsibilities are to clear the infarcted area and activate other cells, such as fibroblasts, endothelial cells and progenitor cells to help the healing process of the blood vessels (Mercola et al. 2011). Tissue regenerative in today’s world uses the stem cell technology to repair, replace and regenerate the cells of the injured organ or tissues. It is a combination of engineering principles and life sciences in order to create something that able to proliferate and regenerate as well as sustaining and improving its functions. This purpose can be achieved by applying functional cells, scaffolds supplementary, stimulate the growth and signal molecules to needed areas. The scaffold delivers as physical support for the cells as well as to function as organizer guiding the cell growth and differentiation (Leor et al. 2005).
They led an electronic and manual search to recognize studies reporting on the subject of accuracy of dental implant impressions. Pooled data were thoroughly analyzed. Factors affecting the accuracy of the implant impression were identified, and their influence on accuracy of the resultant cast was evaluated. The 76 researches that satisfied the inclusion criteria included 4 in vivo studies and 72 in vitro studies. Studies were categorized according to teeth loss; 41studies reported on completely edentulous and 35 studies on partially edentulous patients. They reached the conclusion that the pick-up technique is more accurate than the transfer for patients who have lost all of their teeth, but for partially-edentulous patients there was no significant difference in results between the two
The purpose the study is the presentation of successful use of Signafuse Bone Graft Putty in vivo. Fusion Products are commonly used in the field of Orthopaedics. They serve an important role as far as relieving pain and treating morbidities.
The human body endures a great deal of wear and injury during its lifetime. It is for this reason that the body has several tissues that are capable of regeneration. Bone is one of those tissues that receives extensive use so it is necessary that it is strong in order to carry out its functions; however, it will occasionally face injury. Although our bones are capable of regeneration, a new method would help the elderly and others that have a more difficult time healing after injury. I viewed a “TED Talk” lecture, which discussed a new way of regenerating bone with the help of our own bodies. Molly Stevens, the head of a biomaterials lab, presented “A New Way to Grow Bone” where she discussed a new technique called “in vivo bioreactor”. She also answered why this new procedure is beneficial. Researchers like Stevens are constantly trying to find innovative new techniques and they do this by asking questions. The question that Stevens presented in the video was an intriguing one: “Can we recreate the regeneration of bone on demand and transplant it?”.
In time, the jawbone may severely deteriorate to the point where there will not be enough bone for dental implants to be placed. That’s where bone grafting comes in. Bone grafting is a minor surgical procedure that is intended to build up new bone in the jaw area that is used to hold the teeth. This procedure prepares patients for future dental implants.
The musculoskeletal system is comprised of bones, joints, cartilage, tendons, ligaments, fascia and muscles. Together these body parts work to establish a framework that is the musculoskeletal system. This framework is what gives the body its shape, form, and figure. It stabilizes the body as well as supplies the structural support. The musculoskeletal body features not only provide a framework for your body but allows your ability to create movement. These movements are monitored by the musculoskeletal components which then determine your degree of flexibility. Overall the amount of energy your body uses comes almost entirely from these musculoskeletal functions. Which makes sense because it
The concept of Osseointegration by Branemark has opened up limitless possibilities and rehabilitation to the extent of involving not only single tooth or multiple teeth but also various developmental deformities and also extensive damage of jaws following injuries and resection of tumors. Dental implants have a long history dating back to prehistoric people where in they have used this technology (Bobbio A. Maya 1973, Tapia JL et al 2002). Dr.Norman Goldberg and Dr.Aaron Gershkoff did research on the use of dental implants and published an article in Dental digest in 1949 and a text book on dental implants in the year 1957. In 1965 Branemark an anatomy professor was the first to place dental implants and later on manufactured implants and drills under the compony named Bofors. Since the introduction of implants in dentistry it has become an esthetic, functional restoration which as a long term predictability (Scheller H 1998).
An edosteal implant is surgically placed in the bone can be used to replace a single or
This may be required in cases when the conventional root canal treatment is unable to save the tooth. It is a minor surgical procedure that involves the removal of the very tip of the tooth after which the gap is sealed. An apicoectomy also enables the endodontist to remove any infection or dead debris at the tip of the root. Once the canal is cleaned up and sealed, the risk of infection is very low. In some cases, the endodontist may use bone grafts or other implant techniques to assist with bone growth, especially in cases where the infection has left a big gap. In most cases, the tooth will be salvaged and normal function is
The Skeletal System, also known as the Skeleton make up a framework that support the body and protect the organs. The Skeleton consists of the bones and joints of the body. In the human body there is 300 bones at birth, these then fuse together to make 206 bones in a fully grown adult. The Skeleton is made up of two divisions: The axial and appendicular Skeleton.
