Definition: It is the condition in which no teeth is present in the oral cavity. It is not limited only on old patients, but also it can occur due to repeated extraction of teeth due to dental caries, or periodontal diseases. Moreover, the rates of edentulism increases as age increases, and in communities where they suffer from loss of education.
Sequelae (Consequences) of complete Edentulism:
I) Consequences on the Bony Structure: Fig:1: Bone loss in the edentulous area
Normally, teeth stimulate the surrounding bone by compressive and tensile forces, these forces have a piezoelectric effect (which is the ability of a material to give an electric charge in response to mechanical stress) on the crystals and durapatite that synthesize the inorganic

It affects the mandible more than the maxilla that will affect the facial appearance and substantial modifications in the soft-tissue profile (e.g protrusion of the mandible,lip and chin). Bone loss will accelerate, as long as the patient is not wearing a denture, and if the patient wears any poorly fitting soft tissue prosthesis. Teeth loss leads to remodeling and resorption of the surrounding alveolar bone, thus leading to atrophic edentulous ridges. Gender, hormones, metabolism, parafunction and ill-fitting dentures are considered as factors that increase the amount of bone …show more content…
• Decrease in the facial height Fig: 7: Comparison in the facial height (from dentulous to edentulous state)
• Loss of the labiomental angle which will create a harsh appearance.
Fig: 8: Labiomental angle
• Decrease in the vertical dimension, leading to pseudo-class III malocclusion.
• Rotation of the chin forward creates a prognathic facial appearance. Fig: 9: Chin Rotation
• Decrease in the horizontal labial angle at the lips' corner.
• This short facial appearance, allows the performance of higher bite forces, leading to greater bone loss.
• Thinning of the vermillion border of the lips. Fig:10: Vermillion border in edentulous patient
• Deepening of the nasiolabial groove in the upper lip, so the nose will appear larger and increase in the philtrum angle.
• Maxillary lip becomes longer due to loss of muscle tone.
• The attachment between the body of the mandible and the mentalis and buccinator muscle is affected due to bone atrophy. Fig: 11: Facial Appearance of an edentulous patient
IV) Nutritional Problems:
• Masticatory efficiency will
Beautiful scenery, delicious foods, and desirable accessories at your fingertips along with other enticements and wishes the mall offers as described by Carolyn Merchant as the modern Garden of Eden in her writing of “Eden Commodified.” Merchant is an award winning writer and professor at the University of California covering the subjects of environmental history and philosophy, making her an expert in the subject of human nature and our connection to the environment. She characterizes the combination of gardens, goods, and ornate architecture as heaven on earth a peaceful, clean, and orderly destination for rich and poor, old and young; however, is this really all she is saying?
All primates have essentially the same kinds of specialized mammalian teeth adapted to eating a wide variety of foods. Beginning at the front, each quadrant of the mouth has 2 incisors, 1 canine, and varying numbers of premolars and molars. The incisors are used like scissors for nipping off pieces of food. The pointed canines are for piercing and tearing. The premolars and molars, with their cusps, are used to grind and smash food. In platyrrhine species, there are 3 premolars and 2 or 3 molars. This results in a dental formula of 2.1.3.2 or 2.1.3.3. In contrast, all of the catarrhines have 2 premolars and 3 molars, making a dental formula of 2.1.2.3. The chimpanzee shown below is an Old World anthropoid species and, therefore, has a catarrhine dental formula.
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).
Did The Green Knight poem make allusions to Biblical tales? . Allusions is a vague description of a person, place or thing without being too specific. Allegory is a hidden meaning within a story that one has to discover on his or her own. Green Knight makes allusions towards the bibical tales of The Garden of Eden. The allegoring retelling of The Garden of Eden is apparent in the Green Knight in one big way, temptaion. The symbolic references from both stories are similiar in many aspects.
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.
There are many different diseases that can affect our skeletal system and Osteoporosis is one of them. Osteoporosis lessens bone strength and bone density (amount of bone mineral in bone tissue), which will lead to fragile bones. It mainly affect the hips, ribs, spine, and wrists. Male or female, at any age, can get this but it is mostly occurs in older women (Team, 2016). Osteoporosis is very common, there are more than 3 million cases a year. There are many causes/risk factors, symptoms, and some treatment cases. About 54 million Americans have Osteoporosis and low bone mass (Foundation, 2016).

The gum tissue begins pulling away from the teeth. This creates pockets that allow bacteria to build up, which leads to an infection. As your body fights the harmful bacteria, the bone and tissue holding the teeth in place begin breaking down. The pockets deepen and begin filling with pus. Once you reach this stage, you may need to have surgery to save your teeth. If not treated, the infection begins destroying the bone around the teeth. If the bones, tissue and gums supporting your teeth are destroyed, the teeth may begin to shift, loosen and/or fall out.
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...

In this paper I will clarify the relation between the integumentary system and the skeletal system. During this paper I will address how the two systems work together to maintain homeostasis and what occurs when balance is not maintained between the integumentary and skeletal system. During this paper I will explain how osteoporosis is directly linked between both the integumentary and skeletal system and ways to prevent or yield this disease.
Tactile: Contact with a toothbrush and other oral hygiene devices, eating utensils, periodontal and dental instruments, and friction from prosthetic devices.
