TITLE OF THE TOPIC BIOMECHANICAL STRESSES GENERATED WITHIN THE PERIODONTAL LIGAMENT IN SECONDARY TRAUMA FROM OCCLUSION – A THREE DIMENSIONAL FINITE ELEMENT ANALYSIS.</p><p>6. BRIEF RESUME OF THE INTENDED WORK – 7. 6.1 Need for the study –</p><p>Teeth and their supporting structures are subjected to severe occlusal forces of upto 50 1 kg during mastication . The presence of tissue fluids and arrangement of periodontal</p><p> ligament fibers are such that these intermittent heavy forces can be properly</p><p> accommodated (i.e. adaptive capacity) , without tissue destruction, but the effect of</p><p> masticatory forces on periodontal ligament with reduced bone height remains vague. 2 According to Pihlstrom et al , at given equal clinical attachment levels , teeth with</p><p> evidence of functional mobility and widened periodontal ligament space had about 10%</p><p> less radiographic support than teeth without these findings.</p><p>Based on this fact , the present study aims to assess the alveolar bone loss and its</p><p> consequences on periodontal ligament under normal masticatory loads. There are a few</p><p> clinical studies related to the present topic , may be due to lack of a reliable index for</p><p> measuring the degree of occlusal trauma to which the tooth is subjected.
