Problems solved by technology

Therefore, the actual position of the dentition is different from the occlusal point on the pressure-sensitive paper at the time of analysis, so there is a problem that the occlusal contact position information on the occlusal paper cannot be associated with the accurate position

Embodiment Construction

[0029] FIG. 1 shows a flow of an occlusal pressure analysis method S10 in one embodiment. It can be seen from Figure 1 that the occlusal pressure analysis method

[0030] The process S11 is a process of acquiring occlusal pressure data. That is, the occlusal pressure including the occlusal pressure distribution information is acquired

[0032] In addition, X, Y, P are obtained from the occlusal pressure detection unit

[0035] A more specific operation example is as follows.

[0045] The process S13 is a process of acquiring occlusal contact position data. That is, to obtain two occlusal contact position distributions showing

[0046] Here, the information source of the information showing the occlusal contact position distribution is not particularly limited, for example, such as

[0048] • A source of information showing the location of the occlusal contact on the intraoral photograph.

[0050] The information source of the occlusal contact position is shown on the shape data ...

Abstract

An object of the present invention is to provide an occlusal pressure analyzing device capable of measuring occlusal pressure with high positional accuracy using data obtained by a general-purpose method. For the formula of the arch, calculate the formula for the second arch based on the occlusal contact position data, calculate the transformation matrix that approximates the formula for the first arch to the formula for the second arch, and perform the position including the occlusal pressure data Information is transformed into new positional information by a transformation matrix, and occlusal pressure data including the new positional information is output.

Description

Occlusal pressure analysis device, occlusal pressure analysis program, and occlusal pressure analysis method technical field The present invention relates to a device for analyzing the occlusal pressure in the occlusal contact state of the upper and lower dentition, and the occlusal pressure Analysis program and occlusal pressure analysis method. Background technique [0002] As a means for measuring the nip pressure, pressure-sensitive paper (pressure-sensitive sheet) is known. By biting the pressure-sensitive paper by the subject, On the other hand, the pressure-sensitive paper is strongly pressed at the occlusal contact part of the upper and lower dentition, resulting in a visual change. According to pressure sensitive Depending on the type of paper, it is expressed by a difference in shade or color due to a difference in the magnitude of the nip pressure (contact pressure). so, The occlusal pressure of the upper and lower dentition can be known through the press...
