Occlusion correction improvement instrument and correction improvement method using the instrument

Abstract

An occlusion correction improvement instrument includes an upper mold-mounting member provided with a plate-shaped member that is parallel to a Camper's plane of an upper model having a makeup surface of a maxillary tooth row and with a plane parallel to the Camper's plane when the upper mold-mounting member has been mounted on the upper model; and a lower mold-mounting member mountable on a lower model having a makeup surface of a mandible tooth row and provided with a pin-shaped projection portion that can be fixed, with a position thereof adjusted from side to side and up and down, and with an adjustment member that can adjust a position of the lower mold-mounting member relative to the upper mold-mounting member on the plane parallel to the Camper's plane, with the projection portion abut on the plate-shaped member of the upper mold-mounting member.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an occlusion correction improvement instrument for making the occlusal treatment so that the maxilla and the mandible may make correct occlusion in the physiologic positional relationship between the cranial bone and the mandible bone and to an occlusion correction improvement method using the instrument. [0003] 2. Description of the Prior Art [0004] In the constitution of the occlusion section in a human body, the mandible bone and the mandible tooth row are suspended by means of muscles from the brainpan while the maxillary bone and the maxillary tooth row are attached to the brainpan. For this, even when the mandible section intrinsically has a correct relationship in occlusion relative to the maxillary section, there is a possibility of the mandible section deviating spontaneously from the maxillary section due to the common practice and bad habits of the chewing cycle during the...

Benefits of technology

[0013] To attain the above object, the present invention provides, a first aspect thereof, an occlusion correction improvement instrument comprising an upper mold-mounting member provided with a plate-shaped member that is parallel to a Camper's plane of an upper model having a makeup surface of a maxillary tooth row and with a plane parallel to the Camper's plane when the upper mold-mounting member has been mounted on the upper model; and a lower mold-mounting member mountable on a lower model having a makeup surface of a mandible tooth row and provided with a pin-shaped projection portion that can be fixed, with a position thereof adjusted from side to side and up and down, and with an adjustment member that can adjust a position of the lower mold-mounting member relative to the upper mold-mounting member on the plane parallel to the Camper's plane, with the projection portion abut on the plate-shaped member of the upper mold-mounting member.

Problems solved by technology

For this, even when the mandible section intrinsically has a correct relationship in occlusion relative to the maxillary section, there is a possibility of the mandible section deviating spontaneously from the maxillary section due to the common practice and bad habits of the chewing cycle during the mastication over a long period of time, the action of gravitational pull of the earth, etc.

Furthermore, the deviation of the mandible making the role of a balancer relative to the gravitational pull of the earth produces a distortion from the face to the whole-body posture or a change of the walking manner to possibly exert a burden onto the internal organs and possibly induce symptoms called “the indefinite complaints” that are physical complaints, such as general malaise, dizziness, headache, palpitation, diarrhea, etc.

Therefore, this has raised the problems that the results of improvement on the symptoms obtained by the occlusion treatment differs from one another and that the time required for the occlusion treatment is not constant.

Particularly, it has raised a serious problem to the patients that the technical levels of the dentists are not constant.

Furthermore, since patients have different symptoms, respectively, when they have undergone the same occlusion treatment by the same dentist, the same treatment effect could not be obtained.

In the case of performing the occlusion treatment for the purpose of attaining the physical restoration of the occlusion, when all the physical restoration is to be exclusively applied to the chopping type, persons performing the occlusion of the grinding type will encounter an additional occlusion dysfunction.

Since a superior dental arch on which the instrument is mounted, a desired position of the mandible teeth, etc. are not explicitly described in the prior art, no technical source that enables the mounted instrument to correct the positional relationship between the maxillary teeth and the mandible teeth to a correct one is disclosed.

Furthermore, since no method for manufacturing the instrument, the instrument is difficult to manufacture.

Since the differences among individuals on the upper and lower tooth rows are not taken into consideration, it is difficult to say that this gauge plate is an instrument that can realize ideal occlusion for individual patients, and there is a fair possibility of an individual difference in the occlusion treatment effect arising among the patients.

Furthermore, the gauge plate when a patient has performed occlusion between the upper and lower tooth rows is difficult to visually discern from the outside, resulting in difficulty to make correct measurement.

Moreover, since this gauge plate is an instrument having gauges inscribed on a plate at prescribed intervals, it cannot reply to the differences in width and length of the patients' tooth rows.

This means requirement of preparation of a great number of various kinds of gauge plates so as to deal with tooth rows of different sizes, resulting in occurrence of cumbersome measurement in compliance with patients and time consuming work.

What is worse, where there is no gauge plate suitable for a patient, correct measurement cannot be made.
