Alveolar bone wall thickness measuring device and alveolar bone wall thickness measuring method

Abstract

The invention provides an alveolar bone wall thickness measuring device and an alveolar bone wall thickness measuring method. The measuring device comprises a handle, a connecting sleeve and a metal detector, wherein the handle is provided with an inner cavity and a through hole communicating with the inner cavity; the connecting sleeve is detachably connected with the handle; the metal detector comprises a detection main body and a circuit; a circuit assembly is mounted in an inner cavity of the handle; and the detection main body is rotatably inserted into an inner hole of the connecting sleeve and passes through the through hole to form conductive contact with the circuit. During measurement, the detection main body and a drill bit of a planting machine are tightly attached to the inner wall surface and the outer wall surface of the alveolar bone wall respectively, signals from the drill bit are sensed through the detection main body, electric signals are output after the signals are processed and amplified through the circuit assembly, and the thickness of the alveolar bone wall is measured according to the strength of the output electric signals. By adopting the scheme, the thickness of the alveolar bone wall can be quickly and accurately measured, and the thickness of the alveolar bone wall can be measured in real time while the drill bit works, so that the risk that the alveolar bone wall is drilled through can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an alveolar bone wall thickness measuring device and an alveolar bone wall thickness measuring method based on the alveolar bone wall thickness measuring device. Background technique [0002] In the process of dental implantation, oral implants need to be implanted in the upper and lower jaws of the human body where the teeth are missing. After the wound is healed, dentures are installed on the upper part of the oral implants. When implanting, a cavity needs to be drilled in the alveolar bone with a drill bit, and then the oral implant is placed in the cavity. When drilling the alveolar bone, if the alveolar bone wall is drilled through, it will affect the combination effect of the oral implant and the alveolar bone wall and may also cause complications, which will eventually lead to implant failure. Measuring the thickness of the alveolar bone wall can reduce the risk...

AI Technical Summary

Problems solved by technology

[0003] At present, the alveolar bone wall thickness measurement device used is similar to a vernier caliper, the measurement speed is slow, the measurement result is inaccurate, and a claw needs to be extended into the cavity of the alveolar bone during the measurement process, so it cannot be measured while the drill is working bone wall thickness

However, if you stop to measure the thickness of the bone wall every time you use tools to drill a certain depth, it will undoubtedly prolong the implantation time and increase the pain of the patient. The thickness of the bone wall is roughly judged only by the doctor's experience, therefore, the risk of alveolar bone wall being drilled is still very high
