Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a therapeutic grinding simulation device suitable for use in dental treatment, otorhinolaryngological treatment, and the like.

For example, when a tooth is subjected to grinding treatment using a handpiece in dental treatment, the amount of grinding and the damage caused by the grinding to the patient are mainly determined by the rotational speed of the handpiece and the pressing force of the handpiece against the tooth. Therefore, in order to obtain optimal grinding, it is necessary for the operator to understand these relationships. For example, the pressing force will differ between a user who is "A," and a user who is "B," based on the natural individual differences between the two. These individual differences include the fact that the angle and direction in which the handpiece is pressed against the tooth, in other words, the way it is used, vary depending on the operator's so-called "#".
Grinding power increases or decreases depending on the habit. Therefore, it becomes necessary for the operator to know, for example, the accurate amount of grinding per hour through self-diagnosis. Because excessive grinding of teeth? Of course, this is not something that should be desired from a medical point of view.
Grinding with excessive pressing force promotes a rise in tooth temperature, which has an adverse effect on the pulp tissue.

Particularly, this self-examination 11-1 is extremely important for medical students and inexperienced doctors in order to master the grinding technique. However, no matter how important such self-diagnosis is, it is necessary to avoid using actual human teeth, and it is necessary to perform it using a tooth model whose structure and hardness are similar to those of human teeth. The present invention provides a grinding simulation device having a 4i% performance for this purpose.

Furthermore, the rotation speed of handpieces differs depending on the micro motor, air turbine, air motor, etc., and even handpieces of the same type do not have the same rotation speed depending on the speed reducer and the amount of operation, so the amount of grinding also varies depending on the handpiece used. different.

The present invention provides a grinding device that can grasp changes in the amount of grinding due to the type of handpiece used and the increase/decrease in rotational speed.

Furthermore, in general, in handpiece grinding work, if the pressing force against the object to be ground is increased without performing any operation to change the rotation i& of the handpiece, the rotational speed will decrease, and if the pressing force is decreased, the rotational speed will increase. Even if the number of revolutions decreases by increasing the pressing force against the object to be ground, if the operator further increases the number of revolutions of the handpiece, it is possible to obtain the torque necessary for grinding. However, from the patient's point of view, excessive pushing force is felt as pain. In this way, the environment on the patient's side cannot be determined by detecting only either the handpiece rotation speed or the pushing force, but the relationship between both the handpiece rotation speed and the pushing force. A wide range of information about changing actual grinding operations must be considered. Therefore, this invention detects the rotational speed of the handpiece and the dental load (pushing force) at the same time, thereby determining the most appropriate rotational speed and pressing force for dental treatment, etc. The goal is to help people understand the relationship between

Furthermore, this invention enables self-diagnosis of the amount of grinding and openness during tooth grinding, and learning of grinding techniques, by displaying and transmitting various data associated with this grinding visually, audibly, and sensually. The purpose is to provide a grinding device that can provide diagnostics, etc.
