Influence of neutral zone in complete denture fabrication– A Case Report Abstract Completely edentulous patients wearing dentures since long time have a problem with decreased stability of their mandibular complete dentures because of severe resorption of lower edentulous ridge & altered neuromuscular control. By incorporating neutral zone technique in complete denture fabrication can overcome this problem. Keywords:- Condensation Silicone‚ Neutral Zone‚ Denture stability Introduction In edentulous

Scientists have leaped over a major hurdle in efforts to begin commercial production of a form of carbon that could rival silicon in its potential for revolutionizing electronics devices ranging from supercomputers to cell phones. Called graphene‚ the material consists of a layer of graphite 50‚000 times thinner than a human hair with unique electronic properties. Graphene’s properties are remarkable. Impermeable to gas‚ strongest two dimensional material ever tested‚ with a tensile strength

Lab: Flame Test Purpose: to determine the ID of 2 unknown substances Background Information: Every atom consists of a nucleus with tiny electrons whizzing around it. The further away from the nucleus they are‚ the more energy the electrons have. If a metal atom is heated‚ the electrons get enough energy to jump higher away from the nucleus‚ they become “excited”. When they fall back closer to the nucleus (back to their ground state)‚ they give off this extra energy as light. Why is the

The Spine Changes With Age And Causes Of Back Pain As we age‚ changes back - the spine to age. At the doctor will call signs of aging for degenerative changes. Such changes can be seen‚ among other things‚ on radiographs. With age‚ the joints will often gradually thinner cartilage. It called for cartilage wear or osteoarthritis‚ the x-ray called it usually intervertebralledsartros. The bone in the joints edges becomes stronger and the formation of "pimples". Even vertebral edges are over the years

Evelyn is a well-nourished 80-year-old woman with extensive medical history who recently suffered a femur head fracture that presented as osteoporosis. By definition‚ osteoporosis is a progressive bone disease that leaves the bones weak and unable to sustain any weight or pressure. Osteoporosis occurs when the body makes too little or not enough bone‚ causing the bones to break or fracture easily with a simple fall. Both the spongy and compact bone is affected when osteoporosis is present. The main

Investigation Followup PROCEDURE The purpose of this experiment is to test different minerals to see where on the Mohs hardness scale they would fit. My question and problem‚ “What mineral is the hardest out of all?” My hypothesis is by looking at all mine minerals‚ amethyst is the hardest mineral‚ followed by opal‚ than apatite‚ then halite‚ than graphite and the muscovite will be the softest mineral. To begin this experiment‚ I purchased and gathered all my materials
