step 3, after the first button is pressed, the system enters a treatment state, at the moment, green lamps in display areas of 0, 1, 2, 3, 4 and 5 are flashed, and are respectively turned on and off for 0.5 second, and the operation is carried out in a circulating manner; when the detection sensor enters the middle and weak detection areas, the green light and the red light of the 0, 1, 2, 3, 4 and 5 display areas are both bright and present orange; when the detection sensor enters a strong detection area, a green light of the area 0 is on, and the buzzer sends out two long-time beep sounds to indicate that the implant is found; after marking, the next implant is continuously searched.
10. The method for detecting the position of the oral implant based on the constant current source as claimed in claim 9, wherein the step 3 further comprises the following frequency conversion operations:
the detection sensor is deeply inserted into the oral cavity, and the detection sensor socket is rotated to facilitate detection; pressing the treatment key, namely pressing the first key; the frequency gear is in the lowest gear, then the detection sensor is moved on the tooth surface of the tooth, if the detection sensor enters the planting area, the lamps in the display areas 1, 2, 3, 4 and 5 are orange, namely, the red lamp and the green lamp are simultaneously on; then, the movement is continued, when the detection sensor is positioned at the center of the implant, the green light of the 0 display area is on, and the other lights are not on; if the implant is not detected in the whole process, the frequency gear is gradually adjusted from the medium frequency gear to the high frequency gear under the control of the CPU through the frequency conversion processing of the frequency conversion module according to the selected gear until the implant is detected.
