Title:
THREE-DIMENSIONAL DETECTION DEVICE AND POSITIONING METHOD FOR DENTAL IMPLANT BASED ON CONSTANT CURRENT SOURCE
Document Type and Number:
WIPO Patent Application WO/2023/010888
Kind Code:
A1
Abstract:
The present invention relates to the field of anti-interference and high-sensitivity gum implant detection, and in particular to a three-dimensional detection device and positioning method for a dental implant based on a constant current source. The three-dimensional detection device comprises a detection sensor, a detection sensor socket, and an implant positioning device, and two ends of the detection sensor socket are respectively connected to the detection sensor and the implant positioning device; the detection sensor comprises a PCB substrate and detection coils respectively disposed on the front and back surfaces of the PCB substrate, and the transverse and longitudinal sizes of the involute racetrack-shaped coil on the back surface are 0.1 mm smaller than those of the involute racetrack-shaped coil on the front surface; and the implant positioning device mainly comprises a CPU, a constant voltage source module, a state display control module, and a frequency conversion module which are powered by a power supply. The present invention has the advantages of being high in sensitivity, convenient to operate and accurate in positioning, and the problems that existing methods are long in period, inaccurate in positioning, and low in positioning speed, etc. are solved, thereby ensuring that a doctor rapidly and accurately finds an implant and implements an operation, and reducing medical negligence.
