Evaluating the Effect of Dental Filling Material and Filling Depth on the Strength and Deformation of Filled Teeth
ackground and aim: It is important to evaluate the effect of the type of filling material on deformation and strength of tooth after filling and also the effect of filling depth on quality of restoration of a decayed tooth. Material and Methods: The Orthopantomogram (OPG) of the first and second molars of a 28-year-old man was made and the teeth were 3D modeled. The stress-deformation analysis ...

متن کاملDevelopment and Demonstration of High Concentration Fill Technology on Utilization of Fly Ash as a Filling Material for Underground Coal Mines
A relatively new technology, high concentration backfilling, enables mining industry to think on the use of fly ash as underground back fill material. The advantages are enormous. Jharia and Ranigunj coalfields being the oldest in the country had adopted unscientific mining during pre-nationalization period. In many cases mining was conducted without proper stowing and that had resulted in seve...
متن کاملReducing Dehn filling and toroidal Dehn filling
It is shown that if M is a compact, connected, orientable hyperbolic 3-manifold whose boundary is a torus, and 7‘1, FZ are two slopes on i7M whose associated fillings are respectively a reducible manifold and one containing an essential torus, then the distance between these slopes is bounded above by 4. Under additional hypotheses this bound is improved Consequently the cabling conjecture is s...
متن کاملEffect of respiratory suspension on the computation of volume-based early peak filling rate to late peak filling rate ratio
Background In the intact circulation, changes in intrathoracic pressure and/or lung volume will simultaneously induce alterations in cardiac volumes, output, and contractility among other alterations [1]. In this study, we evaluate the impact of respiratory suspension on the computation of volume-based early peak filling rate (EPFR) to late peak filling rate (LPFR) ratio using peak velocitybase...
