In this paper, SC mapping is integrated with the analytical tooth contour method (TCM) and with orthogonal field diagrams (OFD) to visualize the electric and magnetic field distributions.
Artglass crowns that restored the original tooth contour were cemented with 3 cements: zinc phosphate cement (ZnP), glass ionomer cement (GIC), or a resinous cement in combination with a dentinal bonding agent.
For the electromagnetic analysis, SC mapping is implemented both as a stand-alone method and as an integrated method with the tooth contour method and the orthogonal field diagram method.
To calculate the phase flux linkage as a function of the rotor position, the difference between two magnetic vector potentials located at the stator tooth contour (activated region) is considered.
The cusps of each tooth are then selected to start a local tooth contour and evolve until each tooth bottom is reached.
In TCM, the permeances between relevant tooth contours (TCs) have to be calculated as a function of rotor position.
Various tooth shapes make outlining tooth contours difficult.
This method involves three necessary steps of tooth cavity contour extraction, feature points identification and tooth surface deformation.
However, in FEM, the magnetic vector potential is assumed to be constant along the source-tooth border (contour) line.
This phenomenon not only causes an esthetic disturbance in the anterior region but it may also lead to poor oral hygiene in the posterior region, because molar teeth exhibit contours with prominent convexities leading to accumulation of plaque.
Echocardiographic visualization of the mitral leaflet ventricular septum contact during systole on 2D or M mode, or shark-tooth velocity contour in the LVOT on continuous Doppler flow are diagnostic for SAM.
