However, X-ray imaging can only detect cracks perpendicular to the X-ray beam, and cannot do anything to early longitudinal root cracks. X-ray imaging can only detect these cracks when they intensify and become pulp infection.

Abstract

The invention relates to an oral cavity scanning device and method based on high-frequency ultrasonic. The device is single-vibration-unit ultrasonic probe or a single-vibration-unit ultrasonic probefixed to a mechanical arm, wherein the single-vibration-unit ultrasonic probe is provided with a position sensor and utilizes a gel tooth socket made of ultrasonic gel. The method includes the steps of firstly, using the oral cavity scanning device to scan teeth and periodontal tissue face by face; secondly, using an ultrasonic image segmenting and rebuilding technology to segment and rebuild a target tooth section. The oral cavity scanning device and method has the advantages that tooth and periodontal tissue rebuilding can be achieved in a fast, efficient and zero radiation manner, image acquisition speed and accuracy in oral medicine are increased greatly, and the device and method is high in clinical practical value.

Description

technical field [0001] The invention belongs to the field of medical detection and medical equipment, and relates to an oral cavity scanning device and method. Background technique [0002] In the current clinical practice of stomatology, the methods of obtaining dental conditions mainly rely on making dental models, optical examinations and X-ray examinations. The dental model can visually see the condition of all the crowns, but the production is relatively time-consuming, has many steps, and will be affected by the oral environment. X-rays can diagnose some problems that are not noticeable in appearance, and can accurately see whether there is any abnormality in the condition of teeth. However, X-ray imaging is powerless for some hard tissue loss. Although the radiation dose of modern dental equipment is small, X-rays cannot be used for a long time, especially for patients such as pregnant women. Basically, X-rays are only used in emergency situations. Optical scanning ...
