Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an occlusal diagnostic device suitable for diagnosing the occlusal state of an upper jaw and a lower jaw.
[0002]
[Prior art]
An occlusal diagnostic instrument generally used as a “relator” or “balancer” can not only obtain a lot of information about occlusion from a diagnostic model, but also determines the treatment policy, technical operation, and further of the diagnostic model. It is equipped with various functions such as standardization, and all oral diagnosis and treatment are carried out based on the diagnostic results of this diagnostic device.
[0003]
Whether the upper and lower jaws are occluded, that is, whether the teeth of the upper and lower jaws are in proper contact with each other is an essential element for maintaining health and the five senses. Since the occlusal pressure is evenly distributed through the teeth, there is no tissue damage and the normal functions (functions such as reflexes, nerves and muscles) can be performed normally. Left and right temporomandibular joints, specifically the movement of the muscles around the temporomandibular joints become uneven, causing delays in brain stimulation (information), responses from the brain (command transmission system), posture and facial appearance There is a problem that changes occur.
[0004]
The above-mentioned occlusal diagnostic device capable of diagnosing the right or wrong of an important occlusion is obtained by diagnosing upper and lower jaw diagnostic models made by injecting gypsum into an impression obtained from a patient. The upper and lower jaws are mounted facing each other up and down, and the upper and lower jaws are engaged with each other to diagnose the occlusion. Especially, the maxilla is in the correct position with respect to the skull. Whether or not it is in is an important point of diagnosis.
[0005]
FIG. 9 is a view of an upper jaw diagnostic model obtained from a patient as viewed from the bottom side. In the figure, MK is an upper jaw diagnostic model, MS is a mounting base integrally formed with this diagnostic model MK, MV is an incisor, PN is an incisor pin with a length of about 3mm that is formed by embedding a wire in the incisal papilla part at the time of model formation, ED and ED are left and right incisions (Hamarlarnotch), center line in the center Is the median palatal line marked, and the plane connecting the incisor pin PN of the incisor nipple and the three reference points of the left and right scissors marks ED and ED is H. I. P. In the plane, this H.D. I. P. After mounting the diagnostic model MK on the occlusal diagnostic device so that the plane is parallel to the 0 ° plane, the diagnostic model MK is compared with the 0 ° plane, so that all variations in the occlusal plane can be observed. ing.
[0006]
The circled number 1 shown in FIG. I. P. A normal example parallel to the plane is shown, a circled number 2 indicates a forward ascending, a circled number 3 indicates a respective abnormal example of a back up, and FIG. 11 shows an abnormal example of a left-right mutation, If these abnormal occlusal conditions are treated with the normal state of circled number 1 and the correct occlusal plane is given, tooth neutralization and temporomandibular joint neutralization in the oral cavity will occur, which may occur in the future. It can prevent waxy periodontitis, tinnitus, rhinitis, stiff shoulders, bronchial asthma, snoring, hearing loss, and temporomandibular disorders.
[0007]
[Problems to be solved by the invention]
However, when the conventional occlusion diagnostic device is diagnosed by comparing the mounted diagnostic model with the 0 ° plane, the occlusal diagnostic device is set against the occlusal plane plate horizontally set between the upper jaw base plate and the lower jaw base plate. Since the maxillary base plate on which the diagnostic model is mounted must be moved down to the position where the diagnostic model comes into contact with the knob while rotating the knob (see FIG. 8B), there is a problem that the operation is very time-consuming.
[0008]
In addition, a typical (normal) maxillary dentition has an H.D. as shown by a circled numeral 1 in FIG. I. P. When the diagnostic model MK is compared with the 0 ° plane of the occlusal plane plate as it is, the lower end of the incisor MV hits the occlusal plane plate and the entire diagnostic model MK is circled in FIG. The state shown in the attached numeral 2 , that is, the front ascending state, or conversely, the inclination shown in the circled numeral 3 in the figure becomes the rear ascending state. There is a problem that an error occurs in the diagnosis due to different states.
[0009]
Furthermore, in the conventional occlusal diagnostic instrument, since the lower jaw base plate on which the lower jaw diagnosis model is mounted has a fixed structure, the occlusion with the upper jaw diagnosis model cannot be adjusted after mounting, and the adjustment state (occlusion of occlusion) It was also impossible to measure deviation.
[0010]
Therefore, the technical problem of the present invention is to simplify the work of lowering the diagnostic model until it comes into contact with the 0 ° plane in diagnosing the occlusal state by comparing the diagnostic model mounted on the occlusal diagnostic device with the 0 ° plane. Saving labor and eliminating occlusal plane variation due to incisors.
[0011]
Furthermore, another technical problem of the present invention is to make it possible to adjust the position of the lower jaw diagnostic model and measure the deviation in the occlusal diagnosis of the upper jaw and the lower jaw.
