Description
Technical field
The invention belongs to biologic medical mechanical meaurement device, relate to the measuring method that mankind's meshing functions is relevant.
Background technology
Gmatjpdumamics have another name called masticatory pressure, reflection be the static pressure in fact produced in lower tooth closing course.Its generation comes from lower jaw lifting muscle group and carries out tractive to mandibular bone, makes lower jaw tooth group form the muscular strength of opposing to maxillary teeth group.Gmatjpdumamics be masticatory system different units between (muscle, skeleton and tooth etc.) synergistic result, the mechanical resistance of periodontal tissue can be reflected, contribute to the health status that we understand the tissues such as tooth body, periodontal, masticatory muscles, also can make evaluation to Oral Repair, periodontal treatment and orthodontic treatment curative effect.
The illness of stomatognathic system, such as disorders of temporomandibular joint, serious malocclusion all can cause the remarkable reduction of gmatjpdumamics.Find that the infant of juvenile chronic arthritis is compared with normal children under study for action, maximum biting force reduces, and the persistent period of maximum biting force shortens.In addition, the generation of the dental disease such as odentoschim, vertical root fractures also can affect gmatjpdumamics.A lot of scholar, while research gmatjpdumamics and various diseases relation, also it can be used as the reference index of functional rehabilitation, and such as, gmatjpdumamics is just once by an index of curing as evaluation deciduous teeth dental pulp.In addition, somebody utilizes the vertical dimension that gmatjpdumamics is applicable to measure complete denture.In fact, any part generation illness of masticatory system all may affect normal occlusion power, and therefore gmatjpdumamics is also considered to the important indicator of diagnostics port jaw systemic-function health.And the emphasis also therefore becoming a research measured by gmatjpdumamics.But gmatjpdumamics measurement Research is started late at present, and in existing system, data very single (majority is only with maximum biting force numeric representation), are still short of system, complete metering system.The pathological manifestations such as the measurement of traditional instrument and index of correlation cannot maintain difficulty to similar gmatjpdumamics, gmatjpdumamics fails too early be judged, more cannot system, analyze the mechanical characteristics of muscles of mastication all sidedly.
Utility model patent (201420830767.2) has solved problem mechanical signal being converted to the signal of telecommunication, and just this utility model is only with terminal demonstration maximum and real-time change value.In actual measurement process, we find, the gmatjpdumamics of most of experimenter is difficult to keep stable, and display terminal change in value is exceedingly fast, and is difficult to counting.Especially when requiring " firmly stinging ", numerical value rising and attenuation change are difficult to hold.And during with maximum record, only summarize whole occlusion process with a maximum measurement data, be again incomplete.
Summary of the invention
Based on above-mentioned problem, we recognize and only use maximum and real-time change value to be comprehensive not to analyze the occlusion process of whole reality.Therefore, the present invention proposes comprehensive lasting gmatjpdumamics in regular hour section and measure, draw the method for the extreme value of gmatjpdumamics within a certain period of time, enhancing and the rate of decay and average gmatjpdumamics.Like this, more can resolve the occlusion situation of user comprehensively and accurately, thus the mechanical characteristics of experimenter's muscles of mastication can be analyzed more accurately, all sidedly.
Technical scheme of the present invention is a kind of based on computer assisted gmatjpdumamics measuring method, and comprise the steps: step 1, gmatjpdumamics measuring instrument is connected with computer, and described computer has analytical system and display system; Step 2, user carries out repeatedly firmly occlusion to the occlusion mould of gmatjpdumamics measuring instrument in time t; Described occlusion die nose is provided with the measuring instrument of U-shaped cantilever design, described measuring instrument comprises two symmetrically arranged pole brackets, wherein at least one pole bracket is provided with sensor chip, described sensor chip connecting sensor, described sensor connects terminal display system; Step 3, the described analytical system of described computer depicts the data in time t internal gearing power, and described data are the extreme value of gmatjpdumamics in time t, the rate of decay and average gmatjpdumamics; Step 4, the data of the described gmatjpdumamics in described step 3 are presented in the described display system of described computer.
Further, described sensor chip is arranged on the medial surface of pole bracket ShangUXing mechanism.
Further, described pole bracket is provided with demarcation groove.
Further, described occlusion mould rear end is provided with the groove for preventing sensor.
Further, described groove antetheca is provided with the through hole A passed for sensor input signal line, recess sidewall is provided with the through hole B passed for sensor outgoing signal line.
The beneficial effect that the present invention has:
1) method of the measurement that proposition one is new and analysis gmatjpdumamics, in traditional gmatjpdumamics measuring method, only can measure a maximum gmatjpdumamics or an instant gmatjpdumamics is to reflect the occlusion situation of use, the present invention is then by measuring at the extreme value of certain hour stage internal gearing power, enhancing and the rate of decay and average gmatjpdumamics, more can accurately resolve occlusion situation comprehensively.
2) have analytical system, the measurement data of gmatjpdumamics measuring instrument is by the record of analytical system and analysis thus directly show on the display system, intuitively can be well understood to the concrete condition of user gmatjpdumamics.
Other features and advantages of the present invention will be set forth in the following description, and, partly become apparent from description, or understand by implementing the present invention.
Description of the present invention and accompanying drawing are considered to illustrative and nonrestrictive; on the basis of technical scheme disclosed by the invention; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some of them technical characteristic to replace and distortion, these are replaced and are out of shape all in protection scope of the present invention.
