Description

[Detailed Description of the Invention] This invention provides dental training trainees, etc.
The present invention relates to a dental 11-person body position measuring device for measuring body position, and this learning device has a plurality of oral cavity bearings arranged at a minimum distance of 4 degrees, and each oral cavity bearing car is equipped with a chair.

When a trainee learns using a dental learning device configured in this manner, the scope of work is extremely narrow, and the student often has difficulty learning, making it difficult for the student to learn smoothly.

Therefore, the purpose of this invention is to provide a dental trainee's body position measuring device that eliminates that resistance and allows trainees who have resistance to learning with a dental learning device to smoothly enter into learning. shall be.

According to this invention, the dentist uses the oral cavity as a working point and controls the movement of the body around this point, that is, the range of circular movement of the chair, the positions of the elbows, shoulders, and cervical vertebrae, the direction of the line of sight, and the positions of the knees and hands. It can be measured with a measuring device and obtained in the dimensions of x1Y%Z axis, and by finding common points with the dental learning device using the measurement data and persuading them, learning resistance in the dental learning device can be obtained. ◇ Furthermore, since the movement of the entire body can be measured, this device can improve the training posture and can be used in dental practice.

In addition, by recognizing and convincing people that they have already performed treatment activities as a dentist and that the movements are within the range of i people, they will be able to smoothly enter into re)%/-2 with the above dental learning device without feeling any resistance. can.
