Dental materials

must first complete four years of dental school. Classes that prepare you for this career include anatomy, physiology, microbiology and also classes that are more specified to orthodontist like dental anatomy and occlusion, pediatric dentistry and dental materials. One will also need at least two year of experience in clinics to know that one has had experiences with patients. In order to get a dental license an individual must graduate form an accredited dental school, and complete the written…

extracted from your mouth, and you have a gap where the missing tooth was located, one way you can fill in that gap is with a dental bridge. There are three primary types of dental bridges that your dentist may use to fill in that gap. The type of dental bridge that your dentist uses depends upon your unique situation. Here is a brief rundown of the three primary types of dental bridge options that your dentist may discuss with you. Traditional Bridge The type of bridge that your dentist is…

the terrified dental office. Patients fear pain and the perceived cost involved in comprehensive dentistry. The worst things a person can do is to wait for a toothache to get so bad where they have no choice but visiting the dental office. According to Paul J. Flaer, in his observation he states that, “Fear in approaching the dental visit may be generated by psychosocial factors such as history of bad experience(s) at the dentist and by the effect of poor representations of dental treatment in…

3. Occurrence of the Accident/Incident The freighter SS Fort Stinkine which is a cargo ship arrived at Bombay on Friday, 12 April, 1944 No one in the Dock area was aware about the dangerous cargo which she was carrying. Normally a red flag has to be flagged to indicate the explosive but avoided due to war time.Emergency A certificate has been issued by the Dock yard higher officials to unload it in priority basis. Unloading of the ship commenced immediately. However while unloading the lube…

This lab module covers the subjects of optical spectroscopy of gas discharges and bond stiffness of materials. Optical spectroscopy can be observed using different types of equipment, such as, a spectrometer, a light collecting fiber, and tubes of certain types of gas (He, H2O, H2 and O2). The data collected displays the peak wavelengths for each of the gases, which can be used to determine the energy released when the electrons change energy levels. Overall, it was interesting to see how…

tonnes finish in oceans (Parker 2015). Only 15% of the total plastic production is recycled. The rest of the waste ends up in oceans, beaches, rivers and streets. In fact, the so-called Pacific Garbage Patch is constituted entirely by remnants of this material. Plastics are produced from fossil fuels, a source of clean energy, which causes emissions of greenhouse gases, and non-renewable because in a few years its reserves will be exhausted. But a solution to the problem of plastic waste could…

building is going to take place. The subsoil has to be able to carry these loads. The primary loads are natural loads, forces due to gravity. That are as follows; Dead load This is the permanent elements of the structure, a consistent load as the materials of the house will always be there. The architect can calculate this load. The objects involved are; • Floors • Walls • Ceilings • Slabs • Columns etc Imposed or live load This is the load of all the people in the building, for example in a…

due to various reasons: Uncertainties in loading or environment Defects in material Inadequacy in design Deficiency in construction or maintenance The strength of materials can be increased significantly. But sometimes this comes at the cost of reduced ductility of the material. For example, strength of steel can be increased by manipulating the microstructure. But this increases the brittleness of the material. Thus, a member can fail catastrophically due to crack formation and…

strengths that materials can be tested on: Comprehensive strength and Ultimate Tensile strength. Ultimate Tensile strength is measured by how much stress can a material withstand, while being stretched or pulled apart before breaking, while comprehensive strength is how much van the material resists while being pushed in (together). There is also a Yield Strength- the point at which the material starts to slowly break and cannot come back to it’s shape. Before the yield point of a material, it…

CHAPTER- 5 ANALYSIS OF STEEL LEAF SPRING ________________________________________________________________ The aim of this analysis is to study the multi-leaf steel leaf spring under loading conditions and verify those results within the allowable limits. ANSYS software is used to analyze the stresses and strains by performing static analysis for the given leaf spring specifications and modal analysis is performed to determine the natural frequencies and mode shapes to asses the behavior of the…
