Description

Orthodontic measuring device based on power and torque sensor

Technical field

This utility model belongs to the orthodontics technical field, particularly a kind of measuring device of mouth cavity orthodontic corrective force.

Background technology

In the orthodontic treatment process, orthodontic force is to exist configuration difference to make the arch wire distortion produce restoring force between the actual arrangement shape through the reservation shape of arch wire and tooth to realize.Moving just because of orthodontic force and to the torque at impedance center of tooth realize, therefore studies the active force that arch wire in starting stage and the therapeutic process of orthodontic treatment applies tooth and torque aligns abnormal theory and clinical treatment has great importance.

Domestic orthodontic force measuring device is divided into in-vivo measurement device and in-vitro measurements device at present.For the serious tooth of dislocation, the in-vivo measurement device does not have enough degree of freedom to make the measurement face of device reach the face face with the bracket plane to contact, thereby can only carry out the in-vivo measurement after tooth comes into line.For in-vitro measurements, need before the measurement operator with arch wire and bracket colligation on the tooth mould, complicated operation; For serious wrong jaw abnormality, can't measure; Simultaneously, when in-vitro measurements, need measure orthodontic force indirectly, so certainty of measurement is relatively poor, and error is bigger by means of survey tools such as slide calliper rule.There is the multivariant commercial measurement of employing robot the orthodontic force of arch wire distortion to be measured abroad,, makes cost very expensive owing to adopted the mechanical arm of Automatic Control through force transducer.External report is in addition introduced, and strain gauge is integrated in the sensitive bracket, but each measurement all will be made the tooth mould, and cost is higher, and can only measure a tooth mould at every turn, the program complicacy.In addition, this method need be converted into corresponding power value through date processing with stress value by computer, and just abnormal doctor is not easy to grasp.

The utility model content

This utility model is intended to overcome the defective of prior art; Provide a kind of and can accurately confirm the upper jaw, single on lower jaw or whole three-dimensional space positions of teeth, realize in the body or the orthodontic measuring device based on power or torque sensor of external any or the upper jaw, lower jaw denture.

In order to solve the problems of the technologies described above, this utility model provides following technical scheme:

Orthodontic measuring device based on power and torque sensor; Comprise base for supporting, fixed underpan platform and main body measurement component; Be fixedly connected with the fixed underpan platform on the said base for supporting, be installed with 14 fixed legs on the front end curved edge of said fixed underpan platform; Said main body measurement component comprises vertical axle sleeve, holding ring, horizontal axle sleeve, horizontal feed axle, YOZ plane rotating shaft, XOZ plane regulating part and XOY plane trimming piece; Be socketed with the vertical axle sleeve that moves up and down on the said fixed leg; Said vertical axes puts and is connected with holding ring; The top clamping of said holding ring has horizontal axle sleeve; After said trunnion axis was enclosed within accurate location, horizontal axle sleeve two ends are socket horizontal feed axle, YOZ plane rotating shaft respectively, and said YOZ plane rotating shaft is accurately flexibly connecting with XOZ plane regulating part behind the location; Be socketed with the XOY plane trimming piece on the said XOZ plane regulating part; In the said XOY plane trimming piece microsensor is installed, said vertical axle sleeve and XOY plane trimming piece are regulated the direction of rotation of microsensor at XOY plane jointly, and said main body measurement component is accurately located the back according to different cases and connected through the flush end holding screw.

Further, said base for supporting is the shape of a hoof, and the center is installed with cylinder.

Further, said holding ring top is tabular and is provided with clamping hole.

Further, said YOZ plane rotating shaft one end cylinder, the other end is provided with the spill clamping part, and the clamping lower limb of clamping part both sides has corresponding circular hole.

Further, said XOZ plane regulating part bottom has circular port, and is corresponding with the circular hole of YOZ plane rotating shaft.

Compared with prior art, the utlity model has following beneficial effect:

The main body measurement component can provide three-dimensional fix accurately to any teeth plane, is applied to the location and the interior location of body of tooth mould.Select the number and the position of main body measurement component according to the needs of measuring, realize measurement any single, many or the upper jaw, lower jaw denture, and easy accessibility, be beneficial to cleaning and sterilizing and maintenance.Only also can select installing force or torque sensor to carry out independent measurement as required.Employing power and torque sensor can be realized the output of corona place power and moment fast and accurately.Because the planar any adjustability of sensor installation realizes in the body and external measurement, is not only applicable to clinical common case, also is applicable to the imaginary wrong jaw type in the scientific research.
