There are many problems in using the above instruments to extract teeth. First, the extraction operation mainly depends on the dentist’s experience and technology. It needs a long clinical training to master it proficiently. It is difficult for young doctors to master it. Second, if you encounter a broken tooth root, Above-mentioned instrument can't locate on the residual root, often very troublesome, needs to cut gingiva sometimes, brings a lot of misery to patient; The 3rd, no matter adopt tooth lifter, chisel, hammer or tooth extraction forceps etc. all can cause wound when extracting the residual root of anterior tooth The area is large, which brings pain to the patient and affects the appearance; therefore, it is necessary to seek a minimally invasive tooth extraction device.

The current minimally invasive tooth extraction uses the wedge force and slight rotational force of the minimally invasive tooth extraction knife to cut off the periodontal ligament and squeeze the alveolar bone to increase the gap at the same time, and then use the tooth extraction forceps to extract the tooth with a slight force, although this The minimally invasive tooth extraction method greatly reduces the damage to the periodontal tissue during the entire tooth extraction process.
