the present article‚ the authors investigate the use of flame spheroidized hydroxyapatite particulates in a PEEK polymer for usage as bone analogue materials. Metallic implants have been used for orthopedic implants in the past‚ but polymeric implants have been explored due to stress-shielding issues associated with metallic implants. Wolf’s Law states that if bone is not subjected to mechanical stimuli‚ then it will be absorbed (Uhthoff and Dubuc‚ 1971). Therefore‚ it is important to develop a

Torus mandibularis is described as an unusual benign growth of the bone that protrudes from the lingual aspect of the mandibular alveolar process. These tori develop singly or multiply‚ unilaterally or bilaterally and most often on the premolar region. Mandibular tori are sharply demarcated anteriorly on periapical images and less dense as they extend posteriorly. There is no margin between the periphery of the torus and the surface of the mandible because the torus is continuous with the mandibular

10.1.1 Definition of Healthy Ageing Active ageing is the process of optimizing opportunities for health‚ participation and security in order to enhance quality of life as people age. It applies to both individuals and population groups. Active ageing allows people to realize their potential for physical‚ social‚ and mental well-being throughout the life course and to participate in society‚ while providing them with adequate protection‚ security and care when they need. The word “active”

Anatomy of Knee The knee is composed of 4 bones: the femur‚ tibia‚ fibula and patella. Every one of these bones are practical in the knee joint‚ aside from the fibula. The patellar tendon elongates from the inferior pole of the patella‚ as an extension of the tendon of the quadriceps femoris muscle to the tibial tuberosity. The role of the patella tendon is to transfer the force of the quadriceps muscles‚ much like a rope around a pulley‚ as your knee straightens. (John Miller‚ 2015) Definition

abundant mineral in the composition of bones and teeth. Approximately ninety-nine percent of all calcium in the human body is contained in the teeth and bones (Edwards‚ 58). The remaining calcium is stored in the plasma in two forms: ionized and non-ionized. Non-ionized calcium is bound to proteins (not diffusible through capillaries) or anions (diffusible through capillaries)‚ whereas ionized calcium is free and is found in the heart‚ central nervous system‚ and bones (Regulation of Calcium and Phosphate

The Shoulder Joint.The Shoulder is an enarthrodial or ball-and-socket joint. The bones entering into its formation‚ are the large globular head of the humerus‚ received into the shallow glenoid cavity of the scapula‚ an arrangement which permits of very considerable movement‚ whilst the joint itself is protected against displacement by the strong ligaments and tendons which surround it‚ and above by an arched vault‚ formed by the under surface of the coracoid and acromion processes‚ and the coraco-acromial

breathing difficulty). Osteoporosis: is a medical condition in which the bones become brittle and fragile from loss of tissue‚ typically as a result of hormonal changes‚ or deficiency of calcium or vitamin D. There typically are no symptoms in the early stages of bone loss. But once your bones have been weakened by osteoporosis‚ you may have signs and symptoms that include: back pain‚ loss of height over time‚ a stooped posture or a bone fracture that occurs much more easily than expected. A number of risk

lifestyle of a person plays a role. Lifestyle plays a role in arthritis because not maintaining a healthy body weight applies extra stress on joints which tears them down. Excessive repetitive movements play a role because it eventually deteriorates the bones as they rub against each other. Age plays a role in arthritis‚ because throughout your life your joints will do a ton of rubbing together and eventually will start deteriorating. Inflammation as a reaction to disease plays a role in arthritis because
