Abstract
An apparatus including a bite frame and a bite shaped member is provided. The bite frame includes one or more arcuate frame elements defining an opening for accommodating a mesh element or the bite shaped member that receives a bite registration material for registering a bite impression. The bite shaped member has a geometrical body structure, upper and lower channels of configurable shapes, and upper and lower windows. The upper and lower windows are separated by a space for receiving and allowing flow of the bite registration material to register a vertical distance between the upper and lower jaws. An image processing system operably connected to the apparatus determines the three-dimensional relation between the upper and lower jaws with reference to temporomandibular joints using panoramic images of the upper and lower jaws, reference points provided by radio-opaque markers, three-dimensional scanned images of the bite impression, and three-dimensional head surface images.
