Problems solved by technology

However, the traditional dental handpieces have the following problems in actual use: first, when the traditional dental handpieces are in use, especially the electric dental handpieces, because the motor generates a lot of heat when it works, it will wear the relevant parts in the dental handpieces for a long time. to adverse effects, resulting in easy damage after long-term use

Second, the high temperature of the motor increases the temperature on the surface of the mobile phone. During the operation, the doctor is likely to burn the patient's oral skin, posing a safety hazard.
