Description
Technical field
The present invention relates to medicine equipment Tooth snap-in force technical field of measuring equipment, and in particular to a kind of electronics occlusion is surveyed
Power device and its diaphragm type sensor head preparation method, it is mainly used in real―time precision measurment, mark, record, analysis mankind's mouth
Mechanical information during chamber masticatory movement on occlusal surface.
Background technology
Snap-in force also known as masticatory pressure, reflection is caused static pressure actually in lower tooth closing course.It is produced
The muscular strength that source of students is pulled to mandibular in lower jaw lifting muscle group, makes lower jaw tooth group form resistance to maxillary teeth group.Snap-in force
Be masticatory system different units between (muscle, bone and tooth etc.) result for acting synergistically, the power of periodontium can be reflected
Tolerance is learned, contributes to us to understand the health status of the tissues such as tooth body, periodontal, masseter, oral restoration, periodontal can also be controlled
Treat and orthodontic treatment curative effect makes evaluation.
The illness of stomatognathic system, such as disorders of temporomandibular joint, serious dentognathic deformity can all cause the notable of snap-in force
Reduce.The infant of juvenile chronic arthritis is found under study for action compared with normal child, and maximum biting force reduces, maximum occlusion
The duration of power shortens.In addition, the generation of the dental disease such as odentoschim, vertical root fractures can also influence snap-in force.Many scholars
While snap-in force and a variety of disease relationships is studied, also as the reference index of functional rehabilitation, for example, snap-in force was just once
The index cured as evaluation deciduous teeth dental pulp.In addition, using snap-in force, to determine, complete denture is suitable to hang down somebody
Straight distance.In fact, illness, which occurs, for any part of masticatory system may influence normal occlusion power, therefore snap-in force is also recognized
For be diagnostics port jaw systemic-function health important indicator.And snap-in force measurement is also therefore as the emphasis of a research.But mesh
Anteroclusion power measuring study is started late, and in existing system, data are extremely single, and (majority is only with maximum biting force numerical tabular
Show), still it is short of system, complete metering system.The measurement of traditional instrument and index of correlation can not remain tired to similar snap-in force
The pathological manifestations such as decline are judged difficult, snap-in force too early, more can not system, comprehensively analyze muscles of mastication mechanics it is special
Sign.
Snap-in force is one of important symbol for reflecting masticatory system health status, is always oral cavity to its quantitative measurment research
Medical science and biomedical hot issue.Because human body mandibular movement system is lever construction：During occlusion, temporomandibular joint
For fulcrum, rise jaw flesh and be force at ramus of mandible attachment, attach most importance at occlusion, so in occlusion, thin labial teeth stress is small,
Mechanics distribution close to big, the whole mandibular of stress of grinding one's teeth in sleep of fulcrum shows the feature of gradual change with the change of denture position.Sting
If measurement with joint efforts accurate positioning or can not be closed on tooth interference, can a small discrepancy leads to a great error.But at present relatively
Various weak points in terms of accurate positioning exactly be present in conventional snap-in force measurement.
In the prior art, a kind of occlusion force measuring instrument as disclosed in known patent CN204379289U, it includes being engaged mould
Tool, the front end for being engaged mould are provided with the measurement end of parallel flat suspension girder construction, and measurement end is symmetrically arranged outstanding including two
Arm support, demarcation groove is provided with pole bracket, sensor chip, sensor chip are provided with one of pole bracket
Connect sensor, sensor connection terminal display.During use, its can not precise positioning measurement weak point it is as follows：
First, flat cantilevered support structure does not meet the anatomical physiology of normal person's denture, can not avoid adjacent teeth.As shown in Figure 3
Lower jaw permanent teeth, in normal dentition, each tooth close proximity, wherein and it is seamless, during upper lower tooth closure, all teeth are had an effect jointly,
The biteplane of closing is formed (including symmetrical central incisor, lateral incisor, canine tooth, frist premolar, the second premolar teeth, the
One grinds one's teeth in sleep, second molar and third molar).So, using flat bracket measure when, often can not accurate measurement wherein some
Tooth (closes on tooth often to exert a force in biteplate this plane simultaneously), and cause that measured value reflects is stinging for some region
With joint efforts, measurement result poor specificity.If using curved design instead, the contact of adjacent teeth can be avoided, improves accuracy.Secondly,
Common slide-rule dial graticule simultaneously can not ensure the unification of measurement position.As shown in figure 3, the bilateral tooth of physiological denture is from point
Tooth (the 3rd) backward, there is cusp.As shown in figure 4, tooth itself composition does not only have very important thickness, width, also 4
Individual cusp (show 4 cusps on the downside of picture from two angles respectively in Fig. 4, be respectively it is remote in cheek it is sharp, it is near in cheek point,
The tip of the tongue and the remote middle the tip of the tongue near).Even if generic linear mark is placed under some cusp also extremely easily sliding.Other oral cavity is
The confined space closed after being opened before one, in actual measurement, implementer stretches into biteplate the molar region at subject oral cavity rear
When (first molar, second molar and third molar in Fig. 1), stopped by lip and cheek and tongue tissue, it tends to be difficult under direct-view
Whether observation grinds one's teeth in sleep corresponding occlusal position in mark；Even if can be placed under direct-view, when advising subject to be engaged dynamometry,
Muscle affects when subject has an effect, upperlip tends to close, and these all can hinder the observation of tester again, or causes occlusion to be surveyed
Test plate (panel) shifts again.Above various reasons cause position inaccurate, are actually difficult to ensure that the reliability and repeatability of measurement.
Again, the position for being engaged force measuring instrument knuckle is right-angle design, more sharp, and the sharp corner of its metallic weapon holds
Easily the mucous membrane of mouth of gauger is damaged.
