Abstract
The present invention relates to the technical field of dental image display. It provides a dental image display method and a dental handpiece. First, a 3D tooth image is formed via scanning. Then, at each moving position, a light-sensing component and a first camera respectively collect the first and second partial dental arch images, and a positional association is established between them. When the dental handpiece operates in the oral cavity, a second camera captures a real-time image. Based on this image, the partial dental arch image targeted by the handpiece's working component is determined and displayed on the handpiece's screen. This invention overcomes the prior-art problem of blocked sight during operation, facilitating the doctor's work and enabling the handpiece to function as an oral mirror.
