FIG. 1 is a bottom plan view of the maxillary teeth illustrating the palatal expander of the present invention positioned between the maxillary teeth; FIG. 2 is an elevational view of the maxillary teeth showing the palatal expander in the palatal cavity of the upper jaw and taken generally al...
shoot from tongue side, which is connected with basic plastic placed on the cap top on border which passes from chewing surface of the lateral teeth and cutting edge of cutters and canines, not reaching up to transition site of mucous membrane of alveolar shoot into the oral cavity bottom.ABU...

Even with PDL, the simulation will not show alveolar bone remodeling as the teeth are displaced, and the dental movement will be underestimated when using the FEM. As a result, incorporation of PDL still produces an imperfect model. Anterior-micro-implants-facemask (Ant-MI-FM) [−15°] ...
TURBOEXPANDERS 透平膨胀机 Turboexpander is a machine, which continuously converts kinetic energy into mechanical energy. This is done by expanding the high pressure gas from upstream to a lower pressure downstream through the expander. The high pressure gas causes the radial expander to rotate. Rot...
may pass the rotatable element, it is essential that the piston and the rotatable element be in a form which might be said to be roughly in the nature of paired gear teeth. Thus the piston would represent an internal tooth, designed to cooperate with external teeth on the rotatable element...
plate 40 and a bottom plate 39 with proximal ends pivotally connected to member 35 by pins 42. PLates 40 and 39 are each provided with a slot 41 (FIG. 5) for receiving member 35. Thus, ears 59 and 60 are formed on plates 40 and 39 with a pin 42 extending through each ear of ...
(a) Comparison of experiment and simulation; and (b) infrared imaging (IR) on the boiler side-plate. The oute(ra)channel on the boiler is a fluid channel. Fluid en(tber)s in the bottom right corner and exists in the top left corner. EGR flows from left to right. Figure 18. (a...
They found that the radial leakage decreased with the increase in groove depth because the opened grooves produced a continuous throttling effect on the fluid, jet expansion, and energy flow dissipation. Therefore, opening grooves on the top of the scroll teeth can significantly reduce the losses ...
