Fig 1.
The occlusal splint was rigidly attached to a target.
The trajectories of three spots within the target were recorded using the computerized, binocular, 3D trajectory-tracking device.
Fig 2.
The plaster cast assembly was rigidly fixed to the stage of a high-precision triaxial electronic translator.
The translation stage could move linearly along the x-, y-, and z-axes, as well as circularly in three planes (XOY, XOZ, and YOZ) with a recording accuracy of 0.001 mm.
Fig 3.
The curved (arc) trajectories of the three target spots in one plane were shown in white.
Fig 4.
The initial positions of the three target spots were shown in red.
The linear trajectories of the three target spots in three directions were shown in white.
