Background

Dental forceps are instruments used to hold a crown or root of a tooth and to loosen and dislocate the tooth by wedging, rocking, twisting, and pulling. Currently, the forceps are generally divided into four categories, namely dental forceps, root forceps, breast forceps and other tooth extraction forceps.

The first mechanical forceps was designed by John Tomes in 1841 for dental treatment. Currently, the design concept of the tooth forceps is mature. However, in clinical practice, there are still many injuries caused by improper use of dental forceps or an emergency, and the injuries are mainly reflected in the following aspects: 1. uneven application of force by the dental forceps at the base of the teeth causes damage to the teeth; 2. the tooth forceps slide when used for teeth; 3. the tip of the tooth forceps is damaged, so that the patient inhales by mistake; 4. the forceps damage the adjacent teeth and gums.
