Abstract

Abstract A system for analyzing the occlusion condition by inspecting an occlusion condition diagnosing sheet including a pressure-sensitive composite recording sheet structure (Fig.2) having at least one surface coated with wax (24,26). The system comprises: a first scanner for reading the image of dental arch pattern recorded on wax; a second scanner for reading the color densities developed on the pressure-sensitive recording sheet structure; an occulusion pressure detector for converting the color densities into pressures; a graduation display device for converting the occlusion pressures into density graduations to display the same, and output device for outputting the dental arch pattern and/or distribution of the density graduations (Fig.15-20). Further provided is a system for analyzing the occlusion condition by inspecting an occlusion condition diagnosing sheet including a pressure-sensitive composite recording sheet structure. The system comprises a scanner for reading the color density, an occlusion pressure detector for converting the color densities into pressures, a processor for processing the pressures through one or more of plural processings, a mode selector for selecting particular processing mode and output device for outputting the result of processings.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 165 words
A system for analyzing the occlusion condition of a patient by inspecting an occlusion condition diagnosing sheet including a pressure-sensitive composite recording sheet structure and having at least one surface coated with a wax coating layer, comprising: (a) a first scanner for reading the image of dental arch pattern of the patient, the image being recorded on said wax coating layer; (b) a second scanner for reading the color densities developed on said pressure-sensitive composite recording sheet structure, the color densities being in proportion to the occlusion pressures applied by respective occluding teeth of the patient; (c) occlusion pressure detecting means for converting the color densities read by said second scanner into pressures; (d) graduation display means for converting the detected occlusion pressures into the density graduations to display the thus obtained density graduations; and (e) output means for outputting either one or both of said image of the dental arch of the patient and the distribution of said density graduations of respective occluding teeth.
Claim 2
Dependent Claim 44 words
The system of claim 1, wherein said output means comprises display means and wherein said image of the dental arch of the patient and the distribution of said density graduations of respective occluding teeth are displayed on said display means in the overlapping condition.
Claim 3
Dependent Claim 63 words
The system of claim 1, wherein a single scanner is provided to serve both as said first and second scanners such that said single scanner is operable to serve as said first scanner at any desired time and operable to serve as said second scanner at the time other than the time duration when it is used to serve as said first scanner.
Claim 4
Dependent Claim 55 words
The system of claim 1, wherein said wax coating layer has a color differentiated from the color developed on said pressure-sensitive composite recording sheet structure, and wherein said first scanner selectively senses the color of said wax coating layer and said second scanner selectively senses the color developed on said pressure-sensitive composite recording sheet structure.
Claim 5
Dependent Claim 24 words
The system of claim 1, wherein said graduation display means displays the change in occlusion pressure in terms of the change in color tone.
Claim 6
Dependent Claim 19 words
The system of claim 1, wherein said output means comprises a printer which may print out a printed image.
Claim 7
Dependent Claim 46 words
The system of claim 1, wherein said output means comprises display means for displaying the image of dental arch pattern in a certain color and for displaying the occlusion pressures in color tones different from said certain color used for displaying said image of dental arch.
Claim 8
Independent Claim 132 words
A system for analyzing the occlusion condition of a patient by inspecting an occlusion condition diagnosing sheet including a pressure-sensitive composite recording sheet structure having both surfaces sealingly covered with water-impermeable layers, comprising: (a) a scanner for reading the color density developed on said pressure-sensitive composite recording sheet structure, the color density being in proportion to the occlusion pressure applied by respective occluding teeth of the patient; (b) an occlusion pressure detector for converting the color densities read by said scanner into pressures; (c) a processor for processing the pressures through plural sorts of processing; (d) a mode selector means for selecting a particular processing from said plural sorts of processing; and (e) output means for outputting the result of operation processing carried out under the instruction fed through said mode selector.
Claim 9
Dependent Claim 65 words
The system of claim 8, further comprising: (f) graduation display means for converting the occlusion pressures detected by said occlusion pressure detector into the density graduations to display the thus obtained density graduations; and wherein said output means comprises display means for displaying the distribution of said density graduation of respective occluding teeth together with the result of operation processing carried out by said processor.
Claim 10
Dependent Claim 25 words
The system of claim 8, wherein said processor operates to find the geometric mean of the occlusion pressures in the dental arch of the patient.
