specific Embodiment approach 1

[0019] Specific implementation mode one: see figure 1 , the method for forming an orthodontic arch wire according to the specific embodiment is carried out according to the following steps: Step 1. The K-type thermocouple wire connected to the arch wire by spot welding is used to measure the processing temperature of the arch wire to be processed. The temperature reached by the arch wire under different currents, and the current-temperature curves of different types of arch wires are established, for example image 3 The current-temperature change curve of the nickel-titanium arch wire whose model is F1722 is shown; step 2, determine the model of the arch wire to be processed and the temperature of the arch wire to be processed; step 3, according to the current-temperature change curve obtained in step 1, Obtain the current value required by the archwire to be treated during heat treatment; Step 4, set the heating time for the archwire to be treated; Step 5, use a DC power sup...

specific Embodiment approach 2

[0020] Specific implementation mode two: see figure 1 The difference between this specific embodiment and specific embodiment 1 is that in step 1, during the measurement process, the heating time for each current value to the nickel-titanium arch wire is 7 seconds. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Specific implementation mode three: see figure 2 The orthodontic archwire forming device according to this specific embodiment consists of a central processing circuit 1, a digital Analog converter 7, power module 4, power supply module 6, first analog-to-digital converter 2 and first amplifying circuit 3 are composed; the current control signal output end of central processing circuit 1 is connected to the input end of digital-to-analog converter 7, digital-to-analog The output end of the converter 7 is connected to the power control end of the power module 4, the power module 6 provides a constant DC voltage for the power module 4, the constant current output by the power module 4 is supplied to the arch wire 5 to be processed, and the constant current output by the power module 4 is The feedback signal is amplified by the first amplifying circuit 3 and input to the input end of the first analog-to-digital converter 2, and the output end of the first analog-to-digita...

Abstract

The present invention relates to orthodontic arch filament forming method and apparatus, and is especially orthodontic arch filament heat treatment method and apparatus. The orthodontic arch filament heat treatment method and apparatus has a central processing circuit with stored arch filament heat treatment current-temperature curves. During heat treatment of arch filament, the central processing circuit controls the power output module to output required heating current so as to control the heating temperature while monitoring the real-time temperature and controlling the arch filament bending process effectively.

Description

technical field [0001] The invention relates to a novel heat treatment method and device for an orthodontic arch wire. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of life. Having beautiful and neat teeth not only improves a person's confidence in social interactions, but also prevents many oral diseases (such as severe dental caries, periodontal disease, etc.) etc.) occur. Therefore, the proportion of orthodontic treatment for patients with deformed dentition has greatly increased, especially for the growing adolescent population. The hottest field in medical research. [0003] At present, the development and progress of fixed orthodontic technology represents the general development trend of orthodontic technology. The most commonly used orthodontic arch wires in fixed orthodontic technology include stainless steel arch wire, nickel-titanium alloy arch wire and some non-ferrous metal ar...
